The motor shaft of the driving motor is fixedly connected with a clamping rod 461, and the clamping rod 461 is located in the adjacent sliding cylinder 450. The top end of the screw rod 441 is provided with a universal joint 443, and the top end of the screw rod 441 is fixedly connected with the bottom end of the universal joint 443.

[0030] Embodiment Two

[0031] On the basis of Embodiment One, a rotating block 470 and a rubber plate 471 are arranged to increase the contact area between the rotating frame 420 and the outer side wall of the wind power tower cylinder.

One end of the torsional spring is fixedly connected with the one end of the rotating block 470, and the other end is fixedly connected with the one end of the rotating frame 420. The one side of the rotating block 470 is fixedly connected with a rubber plate 471. The one end of the rubber plate 471 is provided with a receiving groove 472, and the receiving groove 472 is provided with an electromagnet. The top surface of each pedal 200 is provided with a plurality of cutting grooves 201.

[0033] In the embodiment, the rotating block 470 always makes the adjacent rubber plate 471 move towards the wind tower under the action of the adjacent torsion spring. When the other end of the rotating frame 420 rotates towards the outer wall of the wind tower, the rubber plate 471 first contacts the outer wall of the wind tower, thereby increasing the contact area between the rotating frame 420 and the wind tower and improving the friction between the rotating frame 420 and the outer wall of the wind tower, thereby improving the supporting and fixing effect on the plurality of arc-shaped plates 100. Then the electromagnet in the plurality of rubber plates 471 is started. Since the wind tower is generally made of steel, the electromagnet can be adsorbed on the outer wall of the wind tower, further improving the supporting and fixing effect of the rotating frame 420 on the plurality of arc-shaped plates 100. The cutting groove 201 on the pedal 200 can increase the friction between the sole of the user and the surface of the pedal 200, and the user can also sit on the pedal 200 to rest.

[0034] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments but can be implemented in other embodiments without departing from the spirit or essential characteristics of the application. Consequently, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that, although the present specification is described in terms of embodiments, not every implementation embodies an independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
