1. An implement comprising a head part, a drive part adjoining the head part in a longitudinal direction, which drive part is associated with an actuating member which is drivable in opposite directions, which actuating member is coupled to a toggle lever mechanism via which mechanism an arm of a toggle-lever device is drivable, the drive part having an electric motor which drives the toggle lever mechanism via a transmission device, and wherein a worm is coupled to a shaft of the electric motor, which worm together with a worm gear wheel which is engaged by said worm is disposed in an interior space of the head part, a dog coupled to the worm gear wheel, and a swing pivot coupled to said dog, a longitudinal axis of said swing pivot being parallel to a shaft of the worm gear wheel, said swing pivot of the dog having coupled to it on diametrically opposite sides of the wheel two respective connecting levers which engage said pivot between them, each of the levers cooperating with respective members of the toggle lever mechanism.2. The implement according to claim 1, wherein the shaft of the worm is rotatably mounted in the interior space of the head part by two spaced apart bearings.3. The implement according to claim 1, wherein each connecting lever is comprised of two lever members the longitudinal axes of which are at a mutual oblique angle, an apex of this angle being disposed laterally of the longitudinal axis of the worm and being directed away from said axis so that when the implement is in its open position the lever members of each connecting lever extend around the shaft of the worm gear wheel at an overall angle of greater than 180°.4. The implement according to claim 1, wherein an end region of each of the connecting levers farthest from the dog and the swing pivot is rotatably coupled on a pin which bears respective guide rolls on the pin's respective end regions, each of the guide rolls being forcibly guided in rotational movement with a respective longitudinal guide groove, the grooves being formed in interior sides of a housing of the head part and extending mutually parallel and parallel to the longitudinal axis of the worm and the shaft of the worm, whereby a member of the toggle lever mechanism is disposed between the connecting levers, which member is rotatably mounted in the middle cross sectional plane across an axis of the pin.5. The implement according to claim 4, wherein each of the guide rolls is rotatably mounted using a bearing.6. The implement according to claim 1, wherein the shaft of the worm gear wheel extends outwardly from the head part, such extension being on at least one side of the head part, and such extension bearing at least one coupling being connectable to at least one hand lever for manual actuation of the implement.7. The implement according to claim 1, further comprising at least one sensor disposed in the interior space.8. The implement of claim 7, wherein the at least one sensor is one of a microswitch, an inductive switch, and a pneumatic switch.9. The implement of claim 7, wherein the at least one sensor is displaceable from the interior region of the head part.10. The implement according to claim 7, wherein the at least one sensor is disposed on a sheet metal piece thereby forming a single replaceable module.11. The implement according to claim 10, wherein said replaceable module is insertable into the inner space of the head part via a slot formed in the head part, said module sealing said slot impermeably with respect to the exterior of the head part.12. The implement according to claim 10, wherein suitable attachment means in the form of at least one of threaded blind holes, quick connections, and bores are provided on all four sides of the head part, whereby the replaceable module is insertable and removable when necessary without disturbing the mounting or operation of the tool, such insertion or removal being facilitated by slots for the module provided on each of the four sides of the head part.13. The implement according to claim 12, further comprising threaded attachment holes provided on both sides of each slot to permit a cover to be coupled over any unused slot.14. The implement according to claim 1, wherein the transmission device is self-locking.15. The implement according to claim 1, wherein the drive part is provided with a battery for an emergency power supply.16. The implement according to claim 1, wherein the worm and worm gear wheel are comprised of a plastic material.17. The implement according to claim 16, wherein at least one of the worm and worm gear wheel is produced from a block of plastic material which in the fluid state bears polytetrafluoroethylene flakes, whereby upon hardening said flakes are uniformly distributed in the mass of the supporting body in a maximally homogenous fashion, whereby when the interengaging surface areas the worm and worm gear wheel are subjected to machining and wear, these flakes become prominent or exposed.18. The implement according to claim 1, wherein the arm is a clamping arm of a toggle-lever clamping device.19. The implement according to claim 1, wherein the arm includes a welding electrode of a toggle-lever welding arm.20. The implement according to claim 1, wherein the arm is a broach.21. The implement according to claim 1, wherein the arm is a mandrel.22. The implement according to claim 1, wherein the arm is an impressing device.23. The implement according to claim 1, wherein the arm is a stamping device.
