[0029] When in use, the hard cable is passed through the cable hole 102 of the threading device body 1, and then the anchor column 202 is pressed downward to clamp the cable. In this process, the components undergo the following changes: the anchor column 202 is pressed, and the anchor column 202 pulls the connecting wire 2 to the outside of the threading device body 1, thereby reducing the length of the connecting wire 2 set in the annular groove 103, reducing the area surrounded by the connecting wire 2, and a plurality of friction blocks 201 are pressed against the cable, and the friction between the friction blocks 201 and the cable is increased. Provide the force required for clamping; when no external force is applied, the block 4011 is located in the through hole 301, and when the anchor column 202 moves downward, the chamfered head 2022 squeezes through the gap formed by the two opposing blocks 4011 until the slot 2021 of the anchor column 202 moves to a suitable position and cooperates with the block 4011, thereby limiting the position of the anchor column 202; multiple groups of blocks 4011 and slots 2021 are provided, which are convenient for use with cables of various specifications, thereby improving the flexibility of the device.

[0030] Example 2

[0031] See also Figure 1 , Figures 3 to 5The utility model provides a technical solution: a threading device for laying cables in a pipeline, a slot 302 is provided on the front of the switch box 3, an insertion shaft 5 is inserted in the slot 302, one end of the insertion shaft 5 is fixedly connected to a baffle 501, a side of the baffle 501 away from the insertion shaft 5 is fixedly connected to a movable plate 502, a reset spring 7 is sleeved on the insertion shaft 5, one end of the reset spring 7 is fixedly connected to the front of the switch box 3, and the other end of the reset spring 7 is fixedly connected to the baffle 501.

[0032] When it is necessary to remove the cable, the movable plate 502 is pressed down, the return spring 7 is further compressed, and the elastic potential energy is stored. The movable plate 502 drives the two connecting rods 6 hinged thereto to move, and the acute angle between the connecting rod 6 and the plug shaft 5 is enlarged. Since the end of the connecting rod 6 away from the movable plate 502 is hinged to the side plate 4, the two side plates 4 move back to back, resulting in the distance between the two side plates 4 being enlarged, thereby making the cooperation between the block 4011 and the slot 2021 invalid, so that the state of the anchor column 202 is restored to freedom, which facilitates disassembly and assembly; after the movable plate 502 is released, the return spring 7 releases the elastic potential energy, so that the side plate 4 returns to its original position; when no external force is applied, the return spring 7 in a compressed state plays a role, so that the two side plates 4 have a tendency to approach each other, ensuring the stable connection between the block 4011 and the slot 2021;

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
