Portable hand-operated wring grinder

The utility model relates to a portable hand-operated wring grinder. A wring grinder bracket is arranged on a wring grinder base, a grinder roll is mounted on the wring grinder bracket, a ratchet wheel and a reduction gear are fixedly and coaxially connected in sequence from inside to outside at one end of the grinder roll, a reduction gear is fixedly and coaxially connected to the other end of the grinder roll, the reduction gears at the two ends of the grinder roll are meshed respectively with transmission gears sharing a common axial center and mounted on the wring grinder bracket, the two transmission gears are connected respectively with a stir hand, a ratchet pawl matched with the ratchet wheel is arranged on the wring grinder bracket, the ratchet pawl is repositioned through a ratchet spring on a ratchet pawl rotating shaft, a V-shaped bayonet for clamping and fixing an angle iron and a movable clamping seat corresponding to the V-shaped bayonet are arranged on the wring grinder base, and the movable clamping seat is connected with the wring grinder base through a bolt. By making the best of gear ratio, the utility model reduces the pulling force necessary for hoisting a conducting wire, thereby successfully preventing the conducting wire hoisting process from suffering such defects as large vertical load, time-consuming and labor-consuming hoisting, low work efficiency and poor safety in operations such as replacing a linear insulator, replacing a wire clamp, etc. The utility model is portable, simple to operate, good at safety, and has the effects of improving efficiency and saving manpower.
