[0037] Specifically, the linkage member 103 includes a handle 103a disposed outside the sleeve 101, the handle 103a is pressed by a rotating shaft 103a-1, and one end of the handle 103a is fixedly connected to an operating wire 103a-2.
[0038] Preferably, the linkage 103 further includes a first pulley 103b and a telescopic pulley 103c3c arranged on the inner wall of the sleeve 101, the first pulley 103b is fixedly connected to the inner wall of the sleeve 101, the telescopic pulley 103c3c includes a fixed column 103c-1 fixedly installed on the inner wall of the sleeve 101 and a second pulley 103c-3 fixedly connected to the fixed column 103c-1 through a second spring 103c-2, and the other end of the operating wire 103a-2 passes through the first pulley 103b and the telescopic pulley 103c3c
[0039] Preferably, the linkage member 103 further includes a second rack 103d disposed inside the sleeve 101 and located on the same side as the telescopic pulley 103c3c, one side of the second rack 103d is fixedly connected to the operating wire 103a-2, and the other side of the second rack 103d is fixedly connected to the inner wall of the sleeve 101 through a spring wire 103e.
[0040] Preferably, the linkage member 103 also includes a first gear G disposed inside the sleeve 101 and cooperating with the second rack 103d, the first gear G also cooperating with the first rack 102a-2, the first gear G rotates on a fixed pile 103f, the fixed pile 103f is fixedly connected to the inner wall of the sleeve 101, one fixed pile 103f is disposed on each side of the inner wall of the sleeve 101, and a second gear 103g is disposed on the other fixed pile 103f, and the second gear 103g cooperates with the first rack 102a-2
[0041] Preferably, the positioning member 202 includes a third pulley 202a disposed on the same side of the first pulley 103b, an unlocking line 202b fixedly connected to the unlocking button 201, and a positioning plate 202c disposed on the surface of the fixing pile 103f, the unlocking line 202b passing through the third pulley 202a and fixedly connected to the locking block 202d.
[0042] Preferably, the locking block 202d is fixedly connected to the positioning plate 202c through the third spring 202d-1, and the locking block 202d slides in the positioning plate 202c through the movable shaft 202e, and the locking block 202d can rotate through the movable shaft 202e.
[0043] Usage process: When installing the grounding wire head, hold the sleeve 101 with the palm of your hand, press the lower end of the handle 103a with four fingers, press toward the side of the sleeve 101, pull the operating line 103a-2 outward, and the second rack 103d moves to the lower right corner driven by the operating line 103a-2. At this time, the telescopic pulley 103c moves to the right side under the horizontal pulling force of the operating line 103a-2, so that the second rack 103d engages with the first gear G, driving the first gear G to rotate counterclockwise, and then drives the movable column 102a-1 to move upward, so that the chuck 102 moves upward.
[0044] Then release the handle 103a, the handle 103a is reset under the tension of the spring 23, the second rack 103d is reset under the action of the spring line 103e, and the telescopic pulley 103c loses the tension to the right and resets to the left, driving the second rack 103d to leave the first gear G, preventing the first gear G from rotating clockwise. Repeat this operation process, the clamp 102 will move upward until the conductor is clamped, and the operation can be continued at this time, the spring in the clamp 102 will be compressed, providing a suitable clamping force to ensure that the clamp 102a is fastened to the conductor and does not fall off.
[0045] When the movable column 102a-1 moves upward, the first rack 102a-2 drives the second gear 103g to rotate clockwise, wherein the locking block 202d allows the second gear 103g to rotate only clockwise but not counterclockwise to prevent the clamp 102 from moving downward. The specific principle is: the locking block 202d is always stuck in the second gear 103g under the action of the compression spring 21. When the second gear 103g rotates clockwise, the locking block 202d is activated by the movable shaft 202e and will be pushed outward. When the second gear 103g rotates counterclockwise, the locking block 202d cannot rotate, so the second gear 103g will be blocked by the locking block 202d, thereby preventing the second gear 103g from rotating counterclockwise.
[0046] When removing the ground wire head, just press the unlocking button 201. At this time, the operating wire 103a-2 pulls up the locking block 202d along the direction of the fixed pile 103f. The second gear 103g loses the lock spindle and can rotate counterclockwise, driving the movable column 102a-1 to move downward, driving the clamp 102 to move downward, and then the clamp 102a can be removed from the conductor.

[0049] Furthermore, the current transformer 301 is used to detect the current magnitude, which is directly displayed on the display 302 .
[0050] Usage process: The current transformer 301 can detect the current at the detection part, and the current is displayed on the display 302. Since the sleeve 301 and other parts are insulated, it is safe and convenient to use.
