Specifically, the inner ring 41 rotates unidirectionally relative to the outer ring 42 in a preset direction, that is, the inner ring 41 rotates unidirectionally relative to the outer ring 41 in a clockwise direction or a counterclockwise direction;

as shown in fig. 3, in a general situation, when the driving assembly 3 can be normally used, if it is necessary to recover and wind the cable around the drum body 21, the driving assembly 3 is started, the driving end 31 of the driving assembly 3 rotates in a direction shown by R1 in the drawing, that is, the driving end 31 of the driving assembly 3 rotates in a preset direction, and drives the inner ring 41 of the one-way bearing 4 to synchronously rotate in the direction of R1, the inner ring 41 applies a force to the outer ring 42 in the direction of R1, because the outer ring 42 of the one-way bearing 4 can only rotate relative to the inner ring 41 in the direction of R1, at this time, the driving end 31 of the driving assembly 3 can drive the one-way bearing 4 to synchronously rotate in the direction of R1, so as to drive the drum body 21 to rotate in the direction of R1, and recover the cable.

As shown in fig. 5, in an emergency, the driving module 3 cannot be normally powered on for use, that is, the driving module 3 is powered off, the driving end 31 of the driving module 3 cannot rotate, and thus the spool body 21 cannot be driven to rotate by the driving module 3, at this time, when a cable needs to be recovered, the operator drives the manual rocker 11 to rotate, the manual rocker 11 rotates and acts on an acting force of the outer ring 42 of the one-way bearing 4 to rotate in the direction shown by R1 in the drawing, that is, a force is provided to rotate the outer ring 42 of the one-way bearing 4 relative to the inner ring 41 in the preset direction, because the outer ring 42 of the one-way bearing 4 can rotate relative to the inner ring 41 in the direction R1, so that the spool body 21 can be driven to synchronously rotate in the direction R1 by the outer ring 42 of the one-way bearing 4, and the cable can be recovered. In addition, in the driving process, since the driving end 31 of the driving assembly 3 does not rotate, that is, the inner ring 41 of the one-way bearing 4 does not rotate, the driving end 31 of the driving assembly 3 does not affect the rotation of the one-way bearing 4, and the one-way rotation of the outer ring 42 of the one-way bearing 4 along the preset direction can be ensured.

By adopting the technical scheme, the one-way bearing 4 limits the rotation direction of the inner ring 41 relative to the outer ring 42, so that the winding drum main body 21 can still be rotated through the manual rocker 11 under the condition of power failure of the driving assembly 3, the usability of the winch 100 under various conditions is ensured, and the influence of failure of the driving assembly 3 on an operation task is reduced.
