[0002] The anti-slip pole climber is a special tool used for climbing poles in industries such as electricity, communications, and radio and television, and is designed to improve the safety and efficiency of pole climbing operations. Common pole climbers usually include a footrest for placing the foot and a clamp provided on the footrest for clamping the pole, wherein both the footrest and the clamp are provided with rubber to generate sufficient friction with the pole. However, the prior art has the following problems: in icy and snowy weather, the surface of the pole is frozen, and there is not enough friction between the rubber and the surface of the pole. Therefore, it is necessary to design a climbing pole climber that is fixed to the pole by friction contact under normal conditions, and can be firmly nailed to the pole by sharp nails in rainy and snowy weather.

[0076] The anti-skid sleeve 2 of the anti-skid assembly 7 described in this case can switch the contact surface with the electric pole by rotating:

[0077] Step 1, push the anti-slip sleeve 2 forward to unlock its rotational freedom:

[0078] As the instruction manual Figure 5 , 6 As shown:

[0079] Push the anti-slip sleeve 2 forward, and the anti-rotation plug 22 drives the sliding collar 39, the blocking cross bar 38, the sliding insert 36, and the spring baffle 37 to overcome the damping of the return compression spring 35 and move forward;

[0087] The second round handle 42, the safety spindle 41, and the driving gear 43 are rotated to drive the driven gear 44 and the flat threaded disk 45 to rotate, and the flat threaded disk 45 drives the safety plug 46 to move outward;

[0088] The safety plug rod 46 is stopped in front of the anti-slip sleeve 2 to avoid accidental operation to unlock the rotational freedom of the anti-slip sleeve 2.

[0089] As a further embodiment, the damping of the anti-slip sleeve 2 is also adjusted:

[0090] Rotate the first round handle 32, the rotating core shaft 31 and the external threaded rod 33 to drive the driven nut 34 to move in the front-rear direction;

[0091] The driven nut 34 compresses the return compression spring 35 and adjusts the compression amount and elastic force of the return compression spring 35 in a normal state, thereby adjusting the damping of the anti-slip sleeve 2 when it moves.
