The invention aims to solve the problem that an existing manual processing hammer handle is labor-consuming, and discloses a mechanical hammer handle machining and manufacturing device. The mechanicalhammer handle machining and manufacturing device comprises a sleeve, a first connecting rod, a supporting plate, a supporting rod, a sleeve box, a fastening screw, a rotating disc, a rotating shaft,a base, a motor, a second connecting rod, a screw cap, a spiral spring, a sliding rod, a scraper and a guide ring. The mechanical hammer handle machining and manufacturing device is small in size, convenient for machining a small amount of hammer handles, and capable of replacing manpower, and the problem that a small amount of hammer handles consume resources by using large processing equipment is solved, is more energy-saving and reasonable in design and is worthy of popularization.
