Abstract

A multifunction electric hammer comprises a front-end component and a back-end component. A transmission shaft component (11) of the front-end component comprises a transmission shaft (12), a gear (49) sheathed on the transmission shaft (12), a swing rack bearing (13), a clutch (15) endwise slipping to be meshed or separated with the swing rack bearing (13) and a sliding axle tooth (18). An impacting shaft component (5) of the front-end component comprises an impacting shaft (6), a gear (8) driving the impacting shaft (6) to turn, a piston (9) driving the drill to move along the axial direction. The multifunction electric hammer also comprises a hammer sliding plate (20) sliding axially along the transmission shaft (12), a drill sliding plate (21), a first sliding plate spring (19) connecting the hammer sliding plate (20) with the base (10), and a second sliding plate spring (19') connecting the drill sliding plate (21) with the base (10). The hammer sliding plate (20) is connected with a side guide (33) for sliding the sliding axle tooth (18) to move axially. The drill sliding plate (21) is connected with a side guide (34) for sliding the clutch (15) to move axially. The invention realizes the transformation of the four functions containing hammering, regulating angle, hammering drill and drilling by a button, and has a compact structure, reliable action as well as convenient installation and use.

Description

Technical field [0001] The present invention is a multi -functional hammer in the mechanical industry in the field of electric tool technology, which involves a single hammer, angle adjustment, hammer diamond, and diamond. Background technique [0002] The existing electric hammer of the conversion between hammer, hammer diamonds, diamonds, angle adjustment and other functions with a single knob. When adjusting the function of the hammer drill to the angle of the hammer and the hammer function conversion, the gear component of the kit on the output shaft needs to be promoted.Move, when the hammer and angle adjustment function is changed to the hammer drill function, the gear component relies on the reset spring to promote the reset.The gear component has the function of deduction protection. It consists of gears, shaft sleeves, springs, gear circles, etc. Therefore, the gear component is large, the portion is heavy, and the corresponding pressure of the corresponding reset sprin...
