[0025] The latch 18 can move up and down along the slide groove 20, one end of the latch 18 is installed in the ferrule 17, an arc groove 6 is provided on the inner side of the caliper body 3, and a pressing block 7 is inserted in the arc groove 6, screw holes 4 are reserved on both sides of the surface of the caliper body 3, and screws 5 are engaged and connected in the screw holes 4, a shift block 10 is fixed on the right side of the caliper body 3, and a frosted sheet 11 is pasted on the surface of the shift block 10;

[0026] Specifically, Figure 1 and Figure 2 As shown, fingers pinch the shift block 10 with the frosted sheet 11, so that the pliers body 3 embedded in the first ring 2 through the elastic shaft 8 is tilted up to insert the cable with the connecting accessories. After releasing the shift block 10, the elastic shaft 8 can guide the pliers body 3 to return to the original position for pressing. After completion, the latch 18 is pushed along the slide groove 20 of the hollow block 19 through the slot 9 and into the clamping sleeve 17, which can prevent the elastic shaft 8 from continuing to rotate and prevent the shift block 10 from being triggered inadvertently to separate the pliers body 3.

[0027] Embodiment 2: An inner cavity 16 is longitudinally arranged at the center of the connecting frame 14, and a spacer 27 is fixed at the center of the inner cavity 16. A guide rod 24 is welded to the upper and lower parts of the spacer 27 respectively. A sleeve 23 is sleeved on the outer part of the guide rod 24, and a push block 22 is fixed to the surface of the sleeve 23. A spring 25 is welded between the sleeve 23 and the spacer 27. The push block 22 is attached to the surface of the shift block 10.

[0028] The spring 25 is wound around the outside of the guide rod 24, the sleeve 23 can slide along the outer wall of the guide rod 24, the push block 22 can be embedded in the inner cavity 16 as the shift block 10 is squeezed, and the sleeve 23 and the guide rod 24 are symmetrically arranged at the top and bottom of the spacer 27;

[0029] Specifically, Figure 1 and Figure 3As shown, the surface of the shift block 10 is in contact with the push block 22. When the shift block 10 is pressed to open the pliers body 3, the push block 22 connected to the sleeve 23 is compressed, forcing the push block 22 to enter the inner cavity 16 along the guide rods 24 at the upper and lower parts of the spacer 27 and compress the spring 25. After the shift block 10 is released, the spring 25 that loses the compression can rebound and lift the sleeve 23 and the push block 22 to perform a reset operation.

[0030] Embodiment 3: A second ring 15 is provided on the right side of the connecting frame 14, and a sleeve handle 12 is movably connected to the second ring 15.

After the shift block 10 is released, the elastic shaft 8 can guide the pliers body 3 to reset and press. After the pressing is completed, the latch 18 is pushed along the slide groove 20 of the hollow block 19 through the slot 9 and into the card sleeve 17, which can prevent the elastic shaft 8 from continuing to rotate. Because the surface of the shift block 10 is in contact with the push block 22, when the shift block 10 is pressed to open the pliers body 3, the sleeve will be pressed. The push block 22 connected to the tube 23 forces the push block 22 to enter the inner cavity 16 along the guide rods 24 at the upper and lower parts of the spacer 27 and compress the spring 25. After the push block 10 is released, the spring 25 that loses the compression can rebound and lift the sleeve 23 and the push block 22. A connecting frame 14 is installed horizontally between the main plate 1 and the sleeve handle 12. After the crimping pliers are used, the connecting frame 14 hinged on the left side of the sleeve handle 12 can be rotated to pass the main plate 1, the clamp body 3 and other objects through the upper and lower through grooves 13 respectively and stay in the storage chamber 26, thereby shortening the length of the crimping pliers.
