[0036] Specifically, the second bevel gear 12 can be easily rotated through the knob 13, so as to mobilize the double-sided bevel gear ring 8 to rotate through the meshing transmission. At the same time, the device can be driven to move through the walking wheel 16. The device can be fixed by the fixing plate 14. When it needs to be moved, the armrest 21 can be pressed to lift the fixing plate 14 to move the device. By moving the armrest 21 and inserting the limit rod 23 into the corresponding reserved hole 22, the length of the armrest 21 can be fixed.

The rotation of the first conical gear 9 drives the threaded column 10 thereon to rotate, and drives the positioning sleeve 11 to move along the telescopic tube 7 through threaded connection. The positioning sleeve 11 fixes the pipeline. When the four positioning sleeves 11 are in contact with the inner wall of the pipeline, the inner side of the telescopic tube 7 is the center point of the pipeline. Then pass the cable through the positioning tube 6, start the motor 3 to drive the take-up wheel 4 to rotate, and then the center point of the pipeline can be threaded, realizing automatic alignment of the center point of the pipeline during threading. The cable is positioned so as to reduce the workload of the staff, and by rotating the take-up wheel 4 clockwise, the belt 206 can be used to drive the rotating wheel 205 to rotate, and the rotating wheel 205 drives the lower positioning roller 203 to rotate in a clockwise direction to assist in conveying the top cable. At the same time, the rotation of the positioning roller 203 drives the gear 204 to rotate, and the upper positioning roller 203 rotates counterclockwise through meshing transmission. The upper and lower positioning rollers 203 cooperate to position and convey the cable, so that the cable is automatically fixed and conveyed during threading, without the need for the staff to manually adjust the position, reducing the instability of manual operation, ensuring that the cable remains parallel to the center point, and thus improving the reliability of the device.
