[0002] A winch is a small and light lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects. The winch can lift vertically, or pull heavy objects horizontally or at an angle. The winch is divided into three types: manual winch, electric winch and hydraulic winch. It is mainly used for lifting or towing materials in construction, water conservancy projects, forestry, mining, docks, etc.

[0003] However, when the existing winch is in use, the wire rope after unwinding is easily compressed or the gap in the winding drum is too large, resulting in disordered winding of the wire rope, affecting the next use of the winch.

In view of the above problems, the inventor proposes a quick winch mechanism to solve the above problems. Utility Model Content
