<p>A multifunctional electric tool 100 includes: a housing 1, a motor 11 provided in the housing 1, a spindle 24 which is driven to rotate by the motor 11, and a working shaft 51 which extends to the outside of the housing 1. An active impacting block 31 is provided on the spindle 24, it rotates with the spindle 24 and moves axially relative to the spindle 24. A passive impacting block 41 is provided on the working shaft 51, it rotates with the working shaft 51 and moves axially relative to the working shaft 51. A first end tooth 311 is provided on the active impacting block 31, and a second end tooth 411 is provided on the passive impacting block 41; the active impacting block 31 drives the passive impacting block 41 to rotate through the cooperation of its first end tooth 311 and the second end tooth 411 of the passive impacting block 41; the electric tool 100 also includes a function changeover knob 44, and the function changeover knob 44 can selectively restrict the axial movement of the passive impacting block 41 relative to the working shaft 51 between a first position and a second position, so as to achieve the switch between a first function and a second function. The function changeover mechanism is simple in structure, low cost to manufacture, convenient to operate and can save labor.</p> |
