Abstract
The utility model relates to a self-locking hand winder which comprises a sliding rod, a ratchet wheel and a pawl rod. A bobbin and a hand crank are coaxially mounted in the middle of one side of the ratchet wheel, the sliding rod is vertically arranged above the ratchet wheel, a bilaterally sliding supporting rod horizontally penetrates the middle of the sliding rod, one end of the supporting rod is rotatably connected with one end of the pawl rod, the pawl rod rotates around any point of the middle of a rod body of the pawl rod, and the other end of the pawl rod is fastened with saw teeth of an outer circular surface of the ratchet wheel. The self-locking hand winder is simple in structure and convenient to use, and the ratchet wheel is fastened through pawls, so that the winder can fix the lifting height of an object when in use.
Description
Technical field
The utility model relates to Winder field, particularly relates to a kind of self-locking type hand-operated winding device.
Background technology
