Abstract
A double-speed multipurpose winch allowing a handle to be conveniently locked comprises a speed reduction box. A shifting fork is vertically arranged in the speed reduction box. One end of the shifting fork is connected with a shifting rod which is vertically arranged. The upper end of the shifting rod is connected with a speed regulation rod which is horizontally arranged. The speed reduction handle which is vertically arranged is connected to the speed reduction rod, the lower end of the speed regulation handle is provided with a locking head, a locking hole is formed in the speed reduction box, the locking hole is located below the locking head, and the inner diameter of the locking hole is matched with the outer diameter of the locking head. The handle can be quite conveniently lifted and locked, a user does not need to lift the handle by hand with large force any more, labor is saved, and operation is easy. The situation that danger of locking or even breaking caused when the speed regulation rod frequently bears axial force and deforms is avoided as well.
