[0030] There are two cable clamping blocks 14, and a protective pad 19 is fixedly connected to the outer side of the cable clamping block 14, and the protective pad 19 fits with the cable. This arrangement protects the cable to a certain extent and reduces the occurrence of damage to the cable caused by external force. There are two passive positive and negative screw rods 12, and the passive positive and negative screw rods 12 are evenly and symmetrically arranged on both sides of the active positive and negative screw rods 16. The second mounting block 17 is fixedly connected to the positioning cable clamp 5 and the steering cable clamp 10. This arrangement allows the cable clamping block 14 to slide more stably; the elastic adapter block 9 is arranged between a group of connecting blocks 6, and the first nut 8 is arranged on the outer side of the connecting block 6. This arrangement allows the elastic adapter block 9 to drive the steering cable clamp 10 to turn; a spring 3 is arranged on the inner side of the guide tube 2, and an arc-shaped clamp plate 4 is fixedly connected to the end of the spring 3 away from the inner wall of the guide tube 2, and the arc-shaped clamp plate 4 fits with the positioning cable clamp 5. This arrangement allows cable clamps of different sizes to be placed on the inner side of the guide tube 2.

[0031] Working process: when the hand hole well cable rapid laying device is used to lay the cable, the cable is placed between the cable clamping blocks 14, and the active positive and negative threaded rod 16 is rotated to make the active sliding screw sleeve 15 drive the cable clamping block 14 to slide, and the cable clamping block 14 drives the protective pad 19 to slide.

Then, the second nut 18 is spirally connected to the active positive and negative threaded rod 16 through a tool to fix the cable. When the cable clamping block 14 moves, the passive sliding screw sleeve 13 is driven to slide on the outside of the passive positive and negative threaded rod 12, thereby driving the passive positive and negative threaded rod 12 to rotate with the first mounting block 11, and the passive positive and negative threaded rod 12 clamps the cable. The block 14 can slide more stably, thereby realizing the ability to clamp cables of different sizes. Then, the steering cable clamp 10, the connecting block 6 and the positioning cable clamp 5 are passed through the guide tube 2 and the hand hole well body 1 in sequence. At this time, the arc-shaped clamp plate 4 on the inner side of the guide tube 2 fits with the steering cable clamp 10 and the positioning cable clamp 5. A spring 3 is arranged between the arc-shaped clamp plate 4 and the guide tube 2, so that cable clamps of different sizes can be placed in the guide tube 2. The elastic adapter block 9 and the threaded rod 7 are rotated to make the elastic adapter block 9 drive the steering cable clamp 10 to rotate, and the steering cable clamp 10 drives the cable to steer, so that the cable can be rotated at multiple angles. When the rotation is completed, the threaded rod 7 is limited by the first nut 8 so that it does not rotate, thereby completing the rapid laying of the cable.
