In order to accomplish the goal of the invention of the utility model, the utility model adopts following technical scheme:

A kind of winch handling device of the utility model, it comprises: pull bar, joystick, handgrip, brace, tooth rest, connecting lever, front-end bearing pedestal, rear bearing block and axle, front-end bearing pedestal and rear bearing block are supporting axle; Joystick is sleeved on the axle, drives axle and rotates together, and tooth rest is fixed on the front-end bearing pedestal; The upper end of tooth rest is a circular arc type, and several teeth are arranged on the circular arc, and handgrip is a perpendicular type spanner; Its end and the upper articulation of joystick, an end of its right angle end and brace is hinged, and the joystick bottom has a chute; Move in the joystick chute through a connecting pin bottom of brace, the other end of brace and the engagement of the tooth of tooth rest, and an end of connecting lever is sleeved on the axle; The lower end of the other end and pull bar is hinged, wherein: clump weight is housed on pull bar;

A kind of winch handling device of the utility model, wherein: said clump weight is fixed on the pull bar;

A kind of winch handling device of the utility model, wherein: the upper end of said clump weight is fixed on the pull bar through upper locking nut, and the lower end is fixed on the pull bar through lower locking nut;

A kind of winch handling device of the utility model, wherein: the winch handling device also comprises: spring, an end of spring is fixed on the right angle end of handgrip, and the other end is fixed on the brace.

The winch handling device of the utility model is compared with existing winch handling device, reach compact integral structure, laborsaving, comfortable perfection owing to below pull bar, increase the method for clump weight, and it also has following constructional feature:

1. compact integral structure, rapid operation, comfortable;

2. the draw rod positions space is bigger, and on pull bar, adding clump weight can not influence normal running from handgrip, safe and reliable;

3. clump weight is added on the pull bar, and the action effect of power is direct, and the position is lower, the interpolation of clump weight and dismantle more convenient;

4. clump weight adds jam nut up and down, can landing, there is not potential safety hazard;

5. simple in structure, be convenient to assembling.
