The adjustment component 100 is used to manually adjust the degree of tightening between the entire footrest and the pole, and the anti-skid component 200 is used to automatically tighten the footrest when there is a tendency for the footrest to slide, so as to prevent accidents.

[0032] Specifically, the adjustment assembly 100 includes a climbing pole 101 and a movable pole 103 connected to the climbing pole 101 through a chain 102. Through the cooperation between the climbing pole 101, the chain 102 and the movable pole 103, the electric pole is fully surrounded, which is safer and more reliable.

[0033] The movable rod 103 slides on the climbing pole 101, and the wrapping radius of the pedal is adjusted by manually adjusting the tightening of the chain 102. As the movable rod 103 slides, the chain 102 will be pulled to extend, but because the other end of the chain 102 is connected to the telescopic spring 101c, it will wrap around the pole.

[0034] Preferably, the anti-slip assembly 200 includes a pressure sensor 201 and a control member 202 disposed in the climbing pole 101;

[0035] The pressure information received by the pressure sensor 201 is used to automatically adjust the wrapping radius of the pedal via the control unit 202 .

[0036] When in use, by adjusting the wrapping degree between the footrest and the electric pole, as the staff climbs, the pressure sensor 201 inside the footrest receives the contact force between the climbing pole 101 and the electric pole in real time, and continuously adjusts the tightening force.

[0037] Example 2

[0038] Reference Figures 2 to 5 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the climbing pole 101 includes a contact surface 101a, and an anti-skid pad H arranged on the contact surface 101a. The connection between the anti-skid pad H and the contact surface 101a is connected to the pressure sensor 201. The anti-skid pad H can be made of an anti-skid material with a high friction coefficient that can cope with ice surfaces, such as special rubber, etc. The pressure sensor 201 can be an MPX2010 model, and the pressure sensor 201 can transmit a signal to the motor 202a in real time. The motor 202a is also provided with a receiver that can receive the signal of the pressure sensor 201, and the adjustment parameters are set in advance. The setting of the parameters needs to be verified by experiments to verify the calculation results. The formula of the simulation experiment is as follows:

[0054] Preferably, the control member 202 includes a motor 202a capable of receiving a signal from the pressure sensor 201, and the motor 202a controls the rotation of the rotating rod 101b.

[0055] When in use, the staff presses the unlocking pile 103b to abut against the limiting pile 103a-1, so that the limiting pile 103a-1 is disengaged from the limiting groove A, and then can drive the sliding pile 103a on the movable rod 103 to slide on the climbing pole 101. After wrapping the pole, the climbing begins. During the climbing process, the tightness is manually adjusted;

[0056] During and after the climbing process, if there is a sliding tendency, the real-time monitoring of the pressure sensor 201 will control the motor 202a to tighten in real time to ensure the safety of the user.
