1. A mobile soil-working device comprising: a machine frame,a drive for at least one insertion tool that is capable of being moved up and down and inserted into the ground and pulled out again,the insertion tool being in a starting position at a predefined insertion angle (α) before insertion into the ground and, when in the ground, executing a pivoting movement, which is superposed on the up and down movement, about a first pivot axis in the direction of a first pivoting direction owing to the movement of the machine frame in the direction of travel,at least one returning means, which is coupled to the insertion tool and moves the insertion tool back into the starting position after its exit from the ground by pivoting the insertion tool in a second pivoting direction opposite to the first pivoting direction,wherein the returning means is coupled to at least one protective means, which allows pivoting of the insertion tool in the second pivoting direction beyond the starting position, such that the insertion tool is capable of being pivoted beyond the starting position by pivoting of the insertion tool in the second pivoting direction when it hits a hard object in the ground;wherein a stop is provided that limits the pivoting of the insertion tool in the second pivoting direction when the starting position is reached; andwherein a spring force of a spring means of the protective means is chosen such that the protective means allows the movement of the insertion tool beyond the starting position only when a force is exerted on the insertion tool that exceeds a predetermined force, wherein a plurality of tool holders are arranged side by side, each having a plurality of insertion tools mounted thereto, wherein one returning means is coupled to one tool holder, respectively, wherein a plurality of individual protective means are provided such that the plurality of individual protective means is coupled to each returning means and tool holder. 2. The soil-working device of claim 1, wherein the returning means coupled to the at least one insertion tool is coupled to the protective means via a second pivot joint. 3. The soil-working device of claim 1, wherein the protective means comprises at least a first pivot arm, wherein the first pivot arm is adapted to be pivoted in a third pivoting direction against the spring force of the spring means, wherein the returning means is coupled to the first pivot arm of the protective means via a second pivot joint. 4. The soil-working device of claim 3, wherein the second pivot joint of the returning means is adapted to be moved when the insertion tool is pivoted beyond the starting position, so that the first pivot arm of the protective means, which is coupled to the second pivot joint, can be pivoted in the third pivoting direction against the spring force of the spring means of the protective means. 5. The soil-working device of claim 1, wherein the returning means is a piston-cylinder unit. 6. The soil-working device of claim 1, wherein the tool holder is supported about the first pivot axis in a guide arm adapted to be moved up and down by the drive. 7. The soil-working device of claim 1, wherein a first pivot arm of the protective means is adapted to be pivoted in a third pivoting direction against the spring force of the spring means, wherein a protective means stop is provided that limits the pivoting of the first pivot arm in a fourth pivoting direction that is opposite to the third pivoting direction. 8. A method for working soil comprising: pulling or driving a soil-working device over a soil surface,inserting and pulling at least one insertion tool into and out from the soil, the insertion tool being coupled to a machine frame,wherein, prior to insertion into the soil, the insertion tool is in a starting position under a predefined insertion angle (α) and, when in the ground, performs a pivoting movement about a first pivot axis in the direction of a first pivoting direction due to the movement of the machine frame in the traveling direction, the pivoting movement superposing the up and down movement,wherein, after having left the soil, the insertion tool is returned back to the starting position with the aid of at least one returning means by pivoting the insertion tool in a second pivoting direction opposite to the first pivoting direction, andwherein hitting a hard object in the soil, the insertion tool is pivoted beyond the starting position by pivoting the insertion tool in the second pivoting direction by the aid of at least one protective means;wherein the insertion tool is pivoted beyond the starting position when a force is exerted on the insertion tool that exceeds a predetermined force; andwherein a plurality of tool holders are arranged side by side, each having a plurality of insertion tools mounted thereto, wherein one returning means is coupled to one tool holder, respectively, wherein a plurality of protective means are provided and an individual protective means in the plurality of protective means is coupled to each returning means and tool holder. 9. A mobile soil-working device comprising: a machine frame,a drive for at least one insertion tool that is capable of being moved up and down and inserted into the ground and pulled out again,the insertion tool being in a starting position at a predefined insertion angle (α) before insertion into the ground and, when in the ground, executing a pivoting movement, which is superposed on the up and down movement, about a first pivot axis in the direction of a first pivoting direction owing to the movement of the machine frame in the direction of travel,at least one returning means, which is coupled to the insertion tool and moves the insertion tool back into the starting position after its exit from the ground by pivoting the insertion tool in a second pivoting direction opposite to the first pivoting direction,at least one protective means, wherein the returning means is coupled to the protective means, which allows pivoting of the insertion tool in the second pivoting direction beyond the starting position, such that the insertion tool is capable of being pivoted beyond the starting position by pivoting of the insertion tool in the second pivoting direction when it hits a hard object in the ground;wherein a stop is provided that limits the pivoting of the insertion tool in the second pivoting direction when the starting position is reached; andwherein a spring force of a spring means of the protective means is chosen such that the protective means allows the movement of the insertion tool beyond the starting position only when a force is exerted on the insertion tool that exceeds a predetermined force, wherein a plurality of tool holders are arranged side by side, each having a plurality of insertion tools mounted thereto, wherein one returning means and one protective means is coupled to one tool holder, respectively, wherein an individual protective means is coupled to each returning means and tool holder. 10. A method for working soil comprising: pulling or driving a soil-working device over a soil surface,inserting and pulling at least one insertion tool into and out from the soil, the insertion tool being coupled to a machine frame,wherein, prior to insertion into the soil, the insertion tool is in a starting position under a predefined insertion angle (α) and, when in the ground, performs a pivoting movement about a first pivot axis in the direction of a first pivoting direction due to the movement of the machine frame in the traveling direction, the pivoting movement superposing the up and down movement,wherein, after having left the soil, the insertion tool is returned back to the starting position with the aid of at least one returning means by pivoting the insertion tool in a second pivoting direction opposite to the first pivoting direction, andwherein hitting a hard object in the soil, the insertion tool is pivoted beyond the starting position by pivoting the insertion tool in the second pivoting direction by the aid of at least one protective means;wherein the insertion tool is pivoted beyond the starting position when a force is exerted on the insertion tool that exceeds a predetermined force; andwherein a plurality of tool holders are arranged side by side, each having a plurality of insertion tools mounted thereto, wherein one returning means and one protective means is coupled to one tool holder, respectively, wherein an individual protective means is coupled to each returning means and tool holder, wherein the individual protective means is coupled to the returning means in such a manner as to allow pivoting of the insertion tool in the second pivoting direction beyond the starting position.
