The invention provides a winch clamping-prevention structure, which belongs to the technical field of machinery and solves the problem that the existing winch worm wheel and a worm rod can be easily clamped. The winch clamping-prevention structure is characterized in that a winch comprises a support frame; the side part of the support frame is fixedly connected with a box body; a worm wheel and a worm rod which are mutually engaged are arranged in the box body; a belt wheel is arranged in the support frame in a penetrating way; in addition, one end of the belt shaft is connected with the worm wheel; the clamping-prevention structure comprises a left positioning lug boss, a right positioning lug boss, a left positioning sleeve and a right positioning sleeve; the left positioning lug boss and the right positioning lug boss are projected out of the two sides of the worm wheel; the left positioning sleeve is arranged outside the left positioning lug boss in a sleeving way; the right positioning sleeve is arranged outside the right positioning lug boss in a sleeving way; the inner peripheral wall of the left positioning sleeve is attached to the outer peripheral wall of the left positioning lug boss; the outer peripheral wall of the left positioning sleeve is attached to the inner peripheral wall of the box body; the inner peripheral wall of the right positioning sleeve is attached to the outer peripheral wall of the right positioning lug boss; the outer peripheral wall of the right positioning sleeve is attached to the inner peripheral wall of the box body. The winch clamping-prevention structure has the advantage that the worm wheel and the worm rod cannot be clamped.
