[0029] Reference Figure 2 - Figure 4The right end of the support frame 2 is hinged with a hinged rod 5 for supporting the rotating rod 3, and the top of the hinged rod 5 is hinged with the rotating rod 3 for driving the moving plate 1 to rise. The left end of the rotating rod 3 is rotatably connected to the top of the moving plate 1, and the left end of the rotating rod 3 is fixedly connected with a connecting rod 4 for facilitating the operator to rotate the rotating rod 3. The distance between the hinged joint of the hinged rod 5 and the rotating rod 3 and the connecting rod 4 is greater than the distance between the hinged joint of the hinged rod 5 and the rotating rod 3 and the moving plate 1. The fixed assembly 6 also includes a rack 63 for driving the clamping block 61 to move. The front end of the rack 63 is fixedly connected to the rear end of the clamping block 61. When the rack 63 moves, the clamping block 61 will also move synchronously. The top of the sliding plate 65 is rotatably connected with a gear 64 for driving the rack 63 to move. The gear 64 and the rack 63 are meshed with each other. When the rack 63 moves left and right, it will drive the gear 64 to rotate.

[0030] Reference Figure 1 - Figure 3 , multiple groups of clamp blocks 61, rubber blocks 62, and racks 63 are provided. When fixing, multiple groups of clamp blocks 61 will synchronously fix the cable heads from both sides. Multiple groups of clamp blocks 61, rubber blocks 62, and racks 63 are arranged in a rotating array with the center line of the gear 64 as the rotation axis. Another group of racks 63 is also meshed with the gear 64. By rotating the gear 64, the two groups of racks 63 can be driven to move synchronously inward or outward at the same time.

The top of the rotating block 66 is fixedly connected with a knob 67 for facilitating the operator to rotate the rotating block 66.

[0032] Working principle: When the cable head needs to be removed, the device can be placed on the top of the cable head, and then the knob 67 can be rotated to drive the gear 64 and the rotating block 66 to rotate. The rotation of the gear 64 will drive the rack 63 to move to the middle position, and the rack 63 will drive the clamping block 61 to move to the middle position. The clamping block 61 will drive the rubber block 62 to tightly squeeze the outer wall of the cable head. When the rubber block 62 and the outer wall of the cable head are tightly fitted, the knob 67 can be loosened. At this time, the fixing spring 613 will push the fixing block 69 to make it fit into the inside of the fixing groove 68. At this time, the rotating block 66 will be fixed, and then the connecting rod 4 can be rotated to drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, it will drive the moving plate 1 to move upward through the hinged rod 5.
