[0008] The utility model is further configured that the puncture needle is arranged on both sides of the slide block, and the clamping block is arranged in the middle position of the slide block.

[0009] The utility model is further configured that one end of the hook forms a hook portion corresponding to the slider, the other end of the hook is provided with a fixing platform, the fixing platform is provided with a threaded hole, and an adjusting screw is connected in the threaded hole.

[0010] The utility model is further configured that the hook is provided with a guide groove, the guide groove is arranged along the moving direction of the slider, and the slider is provided with a guide rod which is slidably matched with the guide groove.

[0011] The utility model is further configured that a nut is threadedly connected on the guide rod.

[0012] The utility model is further configured that a bolt is threadedly connected on the side of the sliding block, and also includes an electric connection hanging wire, wherein two ends of the electric connection hanging wire are electrically connected to the bolt and the guide rod respectively.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0014] The piercing grounding wire clamp provided by the utility model can pre-clamp the cable by the cooperation between the clamping block and the hook on the slider. As the slider moves, the clamping block gradually enters the groove, and the piercing needle gradually penetrates into the cable. In this way, since the cable is clamped and fixed by the clamping block in advance, the piercing needle can better penetrate into the cable to form a better electrical connection.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] For reference Figure 1-7 The utility model is described as follows:

[0025] Embodiment 1: A piercing grounding wire clamp comprises a hook 1 and a slider 2.

[0026] One end of the hook 1 forms a hook portion 11 corresponding to the slider 2, and the cross-section of the hook portion 11 is a semicircular ring. The other end of the hook 1 is provided with a fixing platform 12, which is a rectangular structure. The fixing platform 12 is vertically arranged with the hook 1, and a threaded hole 13 is provided on the fixing platform 12, and an adjusting screw 14 is connected to the inner thread of the threaded hole 13.
