The compact carrier platform of claim 5, wherein: a ratchet wheel is coaxially and fixedly arranged on the winding shaft, a locking mechanism is also arranged on the clamping block provided with the tightening driving device, the locking mechanism comprises a pawl capable of moving in a reciprocating manner, and the pawl is provided with a working position and an avoiding position on the reciprocating movement stroke of the pawl;

the pawl is arranged at the working position and is used for being matched with the ratchet wheel so as to prevent the winding shaft from reversely rotating when the winding shaft forwardly rotates to tension the flexible hooping piece;

the pawl is arranged at an avoiding position and is used for avoiding the ratchet wheel so as not to prevent the winding shaft from reversely rotating when the flexible hoop needs to be loosened;

the locking mechanism further comprises a pawl driving structure for driving the pawl to reciprocate between the working position and the avoiding position.

7. The compact carrier platform of claim 6, wherein: and two guide telescopic structures are arranged on the same side of any two adjacent clamping blocks at intervals along the axial direction of the rod piece, and the flexible clamping piece is provided with a flexible clamping part arranged in the interval of the two guide telescopic structures arranged at intervals along the axial direction of the rod piece.

8. A compact carrier platform according to claim 1, 2 or 3, wherein: rolling parts are arranged at the edges of the clamping blocks, which are contacted with the flexible tightening parts.

9. A compact carrier platform according to claim 1, 2 or 3, wherein: the guiding telescopic structure comprises a guiding piece arranged on one of two adjacent clamping blocks and a guiding matching piece arranged on the other clamping block and matched with the guiding piece in a guiding way, and the guiding piece and the guiding matching piece can be separated in the process that the two corresponding clamping blocks are back to back.

10. A compact carrier platform according to claim 1, 2 or 3, wherein: the direction extending structure is including setting up the guide on one of them in two adjacent clamp splice to and set up on another with guide direction complex direction mating piece, at least one direction extending structure on the pole-climbing robot is the direction extending structure that can open and shut, and the guide of the direction extending structure that can open and shut articulates on a clamp splice in two adjacent clamp splice, and the removable fixed mounting of direction mating piece is on another clamp splice.
