The sliding mother seats 12 are sleeved on the upper and lower sides of the screw 15 in a limited manner. The screw 15 is in tooth engagement with the lower sliding mother seat 12. A limiting inner groove 13 is opened inside the lower sliding mother seat 12, and a servo motor 14 that can slide freely is arranged inside the limiting inner groove 13. Limiting sleeve seats 16 are fixedly installed at the four corners on the outer side of the sliding mother seat 12, and a limiting slide bar 17 is sleeved between the limiting sleeve seats 16 at the upper and lower corresponding positions. The limiting slide bar 17 is used as a guiding bar. During the meshing process of the screw 15 and the sliding mother seat 12, the sliding mother seat 12 can slide directionally on the limiting slide bar 17 to prevent deviation. A rod pressing module 18 is fixedly installed on the outer side of the lower sliding mother seat 12, and the rod pressing module 18 passes through the limiting inner groove 13 and is in contact with the servo motor 14;

[0022] The jaw assembly 2 includes a jaw seat 21, a meshing tooth 22, a rack seat 23, a positioning rod 24, a return spring 25 and a sliding clamp 26. A driving motor is fixedly installed inside the jaw seat 21, and a meshing tooth 22 is fixedly installed on the front shaft of the driving motor output. Rack seats 23 are symmetrically arranged on the upper and lower sides of the meshing tooth 22. The rack seats 23 are in engagement with the meshing tooth 22. The rack seats 23 are sleeved on the positioning rod 24, and the positioning rods 24 are fixedly connected to the inner wall surface of the jaw seat 21.

[0023] The working principle of the present utility model is:

[0024] When the utility model is in use, the driving servo motor 14 is driven to rotate the screw rod 15, so that the thread patterns between the screw rod 15 and the lower sliding base 12 are engaged, thereby driving the lower sliding base 12 to slide directionally on the limit slide rod 17, and the limit inner groove 13 is used to accommodate the linkage sliding occurring during the driving of the servo motor 14. Then, the driving motor inside the lower jaw assembly 2 is turned on, so that the meshing teeth 22 and the rack seat 23 are engaged, thereby enabling the sliding clamp 26 to clamp the steel frame on the power tower to fix the overall device. After the detection module 3 detects the current tightening state of the bolt, the servo motor 14 is mortgaged by the abutting rod module 18, thereby blocking the sliding of the servo motor 14. Then, the servo motor 14 is driven to rotate in the reverse direction again. At this time, the lower sliding base 12 remains fixed, and the screw rod 15 will push up the upper sliding base 12, and then drive the driving motor inside the upper jaw assembly 2, so that the meshing teeth 22 and the rack seat 23 are engaged, thereby enabling the sliding clamp 26 to clamp the steel frame on the power tower to fix the overall device, realizing the climbing of the device, realizing automatic detection, and isolating the safety hazards brought by manual climbing.
