As shown in fig. 2 to 5, in the present embodiment, the fixing assembly 21 includes a hanging rod 211, one end of the hanging rod 211 is disposed at the upper end of the lifting rod 1, and the other end of the hanging rod 211 is provided with a hook 2111 for hooking the corresponding cross arm 200, and as shown in fig. 8 to 9, the hanging rod 211 can be inserted from above one of the cross arms 200 to below the other cross arm 200 by using the hook 2111; as shown in fig. 9, when the hook 2111 is inserted from above the right cross arm 200 to below the left cross arm 200 and is hung on the left cross arm 200, the right cross arm 200 can support the hanging bar 211, that is, forms a lever fulcrum, and the left cross arm 200 and the hook 2111 form a limit fit, so that the hanging bar 211 is stably fixed on the two cross arms 200, that is, the connection and fixation between the upper end of the lifting bar 1 and the cross arm 200 are realized, and after the fixation, the hanging bar 211 does not shake, so that the stability is high.

In a specific operation, the two clamping arms 222 are driven to open mutually by the clamping driving piece 223, and then the two clamping arms 222 are held on the electric pole 100; the two clamping arms 222 are then driven toward each other by the clamping drive 223, so that the two clamping arms 222 are held tightly against the pole 100. When the climbing mechanism 3 moves the base 221 up and down, the two clamping arms 222 can slide up and down synchronously along the pole 100, and the roller 224 can convert sliding friction into rolling friction, so that the sliding resistance of the two clamping arms 222 is reduced.

By the arrangement mode, the whole arrangement of the climbing mechanism 3 can be more compact and reasonable.

In addition, in order to improve the maximum static friction force between the clamping wheel 33 and the lifting rod 1, the clamping wheel 33 can be made of materials with proper deformability such as rubber and silica gel, so that the clamping wheel 33 has proper deformability, and can be clamped on the lifting rod 1 more stably, namely, the stability is higher, and meanwhile, the clamping wheel 33 can be adapted to the lifting rod 1 with any shape through deformation, so that the universality is stronger; of course, the clamping wheel 33 is preferably shaped to fit the lifting rod 1 with higher stability.
