1. A handheld power tool, comprising: a drive motor operable via a manual switch for driving a drive body which is associated with a mechanical percussion mechanism and coupled to a percussion member for driving an output shaft provided with a tool receptacle, an operating mode switchover element which is configured to switch over between a normal operation and a percussion operation of the percussion mechanism and which is coupled to the drive body being associated with the percussion mechanism,wherein an operating device, which is coupled to the manual switch and which is coupled to the operating mode switchover element is configured for operating the operating mode switchover element to switchover the operating mode switchover element between the normal operation and the percussion operation of the percussion mechanism by operating the manual switch,wherein the operating device includes a blocking element, a support member, and a spring element,wherein, upon displacement of the manual switch in the axial direction of the handheld power tool up to a predefined distance, the drive motor is operated and the handheld power tool is operated in the normal operation of the percussion mechanismwherein, upon displacement of the manual switch in the axial direction of the handheld power tool beyond the predefined distance, and upon axial displacement of the blocking element and of the support member, and upon elastic deformation of the spring element, the drive motor is operated and the handheld power tool is operated in the percussion operation of the percussion mechanism. 2. The handheld power tool according to claim 1, wherein the operating mode switchover element is designed to block an axial displacement of the percussion member during the normal operation of the percussion mechanism. 3. The handheld power tool according to claim 1, wherein the drive body is configured in a form of a sleeve having an interior in which the operating mode switchover element is mounted. 4. The handheld power tool according to claim 1, wherein the operating mode switchover element is configured in a form of a shaft which is axially displaceable in relation to the drive body. 5. The handheld power tool according to claim 1, wherein the operating mode switchover element is acted on by an associated first spring element in a first axial operating position associated with the percussion operation of the percussion mechanism. 6. The handheld power tool according to claim 5, wherein the operating device is associated with the spring element which is configured to act on the operating mode switchover element in a second axial operating position associated with the normal operation of the percussion mechanism. 7. The handheld power tool according to claim 6, wherein the first spring element has a first spring force which is smaller than a second spring force associated with the spring element. 8. The handheld power tool according to claim 6, wherein the blocking element is clamped by the spring element in an axial direction against the operating mode switchover element in order to act on the operating mode switchover element in the second axial operating position associated with the normal operation of the percussion mechanism. 9. The handheld power tool according to claim 8, wherein the support member is situated between the blocking element and the spring element. 10. The handheld power tool according to claim 9, wherein a gear which is drivable by the drive motor for driving the drive body is situated in the axial direction of the drive body between the blocking element and the support member. 11. A handheld power tool, comprising: a drive motor operable via a manual switch for driving a drive body which is associated with a mechanical percussion mechanism and coupled to a percussion member for driving an output shaft provided with a tool receptacle, an operating mode switchover element which is configured to switch over between a normal operation and a percussion operation of the percussion mechanism and which is coupled to the drive body being associated with the percussion mechanism, wherein an operating device, which is coupled to the manual switch and which is configured to enable a switchover of the operating mode switchover element between the normal operation and the percussion operation of the percussion mechanism by operating the manual switch, is provided for operating the operating mode switchover element,wherein the operating mode switchover element is acted on by an associated first spring element in a first axial operating position associated with the percussion operation of the percussion mechanism,wherein the operating device is associated with a second spring element which is configured to act on the operating mode switchover element in a second axial operating position associated with the normal operation of the percussion mechanism,wherein the operating device has a sliding element which is connected to the manual switch and is configured to elastically deform the second spring element to release the operating mode switchover element in a case of an axial displacement causable by an operation of the manual switch. 12. A handheld power tool, comprising: a drive motor operable via a manual switch for driving a drive body which is associated with a mechanical percussion mechanism and coupled to a percussion member for driving an output shaft provided with a tool receptacle, an operating mode switchover element which is configured to switch over between a normal operation and a percussion operation of the percussion mechanism and which is coupled to the drive body being associated with the percussion mechanism, wherein an operating device, which is coupled to the manual switch and which is configured to enable a switchover of the operating mode switchover element between the normal operation and the percussion operation of the percussion mechanism by operating the manual switch, is provided for operating the operating mode switchover element,wherein the drive body is configured in a form of a sleeve having an interior in which the operating mode switchover element is mounted. 13. A handheld power tool, comprising: a drive motor operable via a manual switch for driving a drive body which is associated with a mechanical percussion mechanism and coupled to a percussion member for driving an output shaft provided with a tool receptacle, an operating mode switchover element which is configured to switch over between a normal operation and a percussion operation of the percussion mechanism and which is coupled to the drive body being associated with the percussion mechanism,wherein an operating device, which is coupled to the manual switch and which is coupled to the operating mode switchover element is configured for operating the operating mode switchover element to switchover the operating mode switchover element between the normal operation and the percussion operation of the percussion mechanism by operating the manual switch,wherein the drive body is configured in a form of a sleeve having an interior in which the operating mode switchover element is mounted.
