[0027] Working principle: First, the staff carries the auxiliary device by the handle 7, and moves synchronously with the device into a narrow space, such as a well. Then the staff inserts the end of the cable into the two semicircular through holes 12. When the cable moves into the arrangement groove 11, it will first contact the elastic member 5 and give pressure to the elastic member 5, so that the elasticity will shrink, thereby increasing the distance between the elastic member 5 and the second guide shaft 14. As the cable is continuously pushed, the movement direction of the cable will change, and it will gradually move along the elastic member 5 and contact the second guide shaft 14. Finally, The cable is discharged through the output slot 16 auxiliary plate, wherein when the cable is in contact with the second shaft 142 in the second guide shaft 14, the cable will synchronously contact with the first shaft 132 in the first guide shaft 13, and the existence of the first shaft 132 and the second shaft 142 can provide the cable with auxiliary sliding force during the process of the staff pushing the cable, thereby reducing the force used by the staff in pushing the cable, thereby increasing the efficiency of cable laying; at the same time, the setting of the first rotating shaft and the second rotating shaft can adjust the bending limit of the cable, which can play a role in protecting the cable; After the cable is laid, first, the staff disassembles the connection between the nut and the screw rod 43 axis on the second box body 3 and the second rod body 141, and disengages the connection between the first rod body 131 and the second box body 3 and the second rod body 141 and the screw rod 43 axis. Secondly, the staff can pull the second box body 3 outward to disengage the buckle structures 6 from each other, that is, the card block disengages from the card slot, wherein the existence of the hinge 2 provides a basis for the rotation of the second box body 3. After the second box body 3 is gradually separated from the first box body 1 as the staff pulls, the arrangement groove 11 will be exposed. Then, the staff can pull the cable to gradually separate the cable from the second guide shaft 14, the first guide shaft 13 and the circular plate through hole. After the cable is separated, the staff pushes the second box body 3 in the opposite direction to connect the second box body 3 with the first box body 1. Finally, the staff can complete the recovery of the auxiliary device through the handle 7.

[0028] It should be noted that the present invention only protects the mechanical part, and the related functions realized by the software control part are not within the protection scope of the present invention.
