Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a ground clamp provided by the present invention.

The utility model provides a ground clamp, including first splint 1, second splint 2, pivot 3, torsional spring 4 and shore device 5, first splint 1 links to each other through pivot 3 with second splint 2, has seted up first pinhole on the first splint 1, has seted up on the second splint with first pinhole complex second pinhole, and pivot 3 passes first pinhole and second pinhole. During clamping or unclamping of a workpiece, the first clamping plate 1 and the second clamping plate 2 rotate about the rotating shaft 3. The first clamping plate 1 and the rotating shaft 3 form a lever structure, and the second clamping plate 2 and the rotating shaft 3 form another lever structure.

As shown in fig. 1, the torsion spring 4 is sleeved on the periphery of the rotating shaft 3, one end of the torsion spring 4 abuts against the first clamping plate 1, the other end of the torsion spring 4 abuts against the second clamping plate 2, under the normal state of not clamping the workpiece, the distance between one end of the torsion spring 3 and the other end of the torsion spring is farthest, in the process of opening the clamping opening to clamp the workpiece, one end of the torsion spring 3 and the other end of the torsion spring are slowly close to each other until clamping the workpiece, and when loosening the workpiece, one end of the torsion spring 3 is separated from the other end of the torsion spring.

As shown in fig. 1, the first clamping plate 1 comprises a first clamping part 11 and a first handle part 12 which are connected, the second clamping plate 2 comprises a second clamping part 21 and a second handle part 22 which are connected, and the jacking device 5 comprises a mounting end and a free end, wherein the mounting end is rotatably connected with the second handle part 22. When the abutting force is insufficient, the top supporting device 5 is rotated until the free end of the top supporting device 5 abuts against the first handle part 12, then the top supporting device 5 is started to enable the top supporting device 5 to extend, in the extending process of the top supporting device, the first handle part 12 and the second handle part 22 are far away from each other, and according to the lever principle, the first clamping part 11 and the second clamping part 21 are close to each other to further clamp the workpiece. The top bracing device 5 can be selected from various devices, and in the embodiment, the top bracing device 5 is a telescopic rod.
