A light single button multi-function electric hammer comprises a body, a motor, a rotation set assembly (1), a cylinder assembly (6), a torque spring (2), a knob (26), a gearwheel and a transmission mechanism of torque clutch. The transmission mechanism of torque clutch comprises a pinion (7), a gear clutch (8), a middle shaft (10), a hammer crosspiece clutch (9), a swing rod bearing (11) and a primary gear (12). The pinion is movably fitted with the middle shaft; the pinion meshes the large end teeth of the gearwheel and matches with the inner teeth of the gear clutch. The gear clutch meshes the small end teeth of the gearwheel and is fitted with the teeth shaft of the middle shaft. The gear clutch and the hammer crosspiece clutch are movably fitted with the teeth shaft of the middle shaft. The swing rod bearing is movably fitted with the middle shaft and is connected with the cylinder assembly through the swing rod. Matched concavo and convex slots are set on the hammer crosspiece clutch and swing rod bearing. The primary gear is tightly fitted with the middle shaft. The knob is connected with an operating mechanism linked to the large teeth end of the gearwheel, the gear clutch and the hammer crosspiece clutch. The electric hammer enables a simple and compact structure, flexible and convenient conversion, low cost, safe and reliable use. |
