Abstract:
A multifunctional electric hammer (100) comprising: a housing (4), a motor (13) provided within the housing (4), a support shaft (1) driven by the motor (13), a function switching part (102), and an output part (103). The output part (103) is provided with a first gear (5) arranged at the left extremity of the support shaft (1) and a reciprocating part (6) arranged at the right extremity. The function switching part (102) is provided with a first pair of clutch sleeve cylinders (2) sleeved on the support shaft (1) and meshed with the support shaft (1), a switching plate (3) supported on the clutch sleeve cylinders (2), and a function knob (8). Slide rails (4a) for accommodating either side of the switching plate (3) is provided on the inside of the housing (4). The function knob (8) drives the switching plate (3) to move left or right along the slide rails (4a) so that the clutch sleeve cylinders (2) mesh with or disengage from the reciprocating part (6), thus achieving the effect of structural simplicity and saving costs when positioning the switching plate (3).
