Compared to embodiment 1, further, the driving member 402b of the winding assembly 402 is configured to provide driving force, including rotation of the winding roller 402c-1 and the adjusting roller 402c-2 of the winding member 402c, the synchronizing wheel 402c-3 slides in the limiting groove 402c-21 through the protrusion T of the inner ring, and the adjusting roller 402c-2 is driven to rotate, so that the synchronizing wheel 402c-3 can be moved laterally on the adjusting roller 402c-2 passively, and reciprocate under the action of the circulating limiting groove 402c-21, so as to correspond to the winding and unwinding process of the winding rope 402a on the winding roller 402c-1, such that the winding rope 402a is wound on the surface of the winding roller 402c-1 in order. It should be noted that the difference in rotational speed between the wind-up roller 402C-1 and the regulating roller 402C-2 can be balanced by regulating the output of the differential C.
The wire binding member 402d is configured to drive the winding rope 402a wound out from the adjusting roller 402c-2 toward the middle, thereby unifying the wire-out or wire-winding direction of the winding rope 402 a. The tending roll 402d-1 is a symmetrical trumpet-shaped roll surface, so that the winding rope 402a has a tendency to move toward the middle of the tending roll 402d-1 during the rotation of the rope pulling, and the winding rope 402a is fed in or fed out from the middle by the further guiding roll 402 d-2.
The protection component 403 may be used for cleaning the outside of the winding rope 402a, where the winding rope 402a passes through the box body at the upper part of the protection box 403a and passes between the limiting members 403b, and is in rotational contact with the rolling wheels 403b-11 of the contact wheel plate 403b-1 in the limiting members 403b, that is, the two rolling wheels 403b-11 arranged in pairs can be attached to the surface of the winding rope 402a to move, and the state of the limiting members 403b is changed through the releasing and retracting process of the winding rope 402 a.
