[0038] Working principle: When installing the grounding device, first insert the grounding rod 1 into the position where the grounding device is installed, then screw the installation cover 3 onto the base 2, then place the connecting wire into the connecting tube 4, squeeze the connecting tube 4, and make the connecting tube 4 clamp the connecting wire. After placing the connecting wire into the connecting tube 4, move the closing box 509 to drive the slider 510 to slide on the surface of the slide rod 511, then squeeze the connecting tube 4 to fix the connecting wire, and then release the closing box 509. At this time, under the action of the elastic force of the first spring 512, the closing box 509 moves close to the push plate 504 and the fitting box 502. After the fixing of the connecting wire is completed, turn the screw 505 to make it rotate on the inner wall of the arc plate 503, and at the same time, the screw 505 rotates on the surface of the push plate 504, thereby controlling the push plate 504 and the rubber head 507 to push the connecting wire. The wiring moves closer to the fitting box 502 on the fixed plate 501 to cover the exposed part of the connecting wire. During this process, the stabilizing rod 506 slides on the inner wall of the arc plate 503 to prevent the push plate 504 from rotating. By setting the connecting plate 508, the closing box 509 can be connected to the fixed plate 501. By setting the sealing device 5, the connection between the grounding wire of the electrical equipment and the connecting tube 4 can be closed, so as to avoid the leakage of electricity due to the exposure of the connecting wire as much as possible, thereby further ensuring the safety of the staff.
[0039] When the rubber head 507 needs to be replaced, the control plate 64 is pushed to slide on the surface of the first limiting rod 65, so that the control plate 64 moves close to the arc plate 503. At this time, the push rod 63 moves away from the arc rod 67, and the restriction on the position of the limiting protrusion 62 is released. Under the action of the elastic force of the third spring 69, the limiting protrusion 62 slides on the surface of the second limiting rod 68, so that the limiting protrusion 62 moves away from the rubber head 507, and the restriction on the position of the rubber head 507 is released. The rubber head 507 is moved away from the push plate 504, and the rubber head 507 to be installed is placed. 07 moves close to the pointed protrusion 61, releases the control plate 64, and under the action of the elastic force of the second spring 66, the push rod 63 moves close to the arc rod 67, thereby pushing the limiting protrusion 62 to insert into the rubber head 507, restricting the rubber head 507, and completing the replacement of the rubber head 507. By setting the replacement device 6, the rubber head 507 can be conveniently replaced when it is worn or aged, thereby improving the convenience of replacing the rubber head 507 as much as possible and improving the efficiency of the staff in replacing the rubber head 507.
