The lower end of the hook steel rope of the utility model surrounds down "? " Shape is installed in the big taper hole of the last young end opening that is provided with on the fixed mount, in taper hole fall "? " The middle vacancy of the hook steel rope of shape is provided with steel rope to moving back contract iron.

The drum shaft of the utility model pass on left captive nut and fixed mount installs and fixes, the right side of drum shaft installs and fixes through bolt of rear end plate and fixed mount.

Hook steel rope of the utility model and turnable being connected of lifting hook, hoist rope with lifting hook.

The beneficial effect of the utility model is: in light weight, simple in structure, easy to carry, safe and reliable.
