Title: ELECTRIC TOOL
Abstract:
An electric tool, comprising: a housing (110); a motor (120); a working shaft (130); a hydraulic impact unit (140) for enabling the working shaft (130) to intermittently rotate and comprising a rotating member (142) fitted onto the working shaft (130); a switching component (160) comprising a clutch member (161) and an operating member (162) driving the clutch member (161). The clutch member (161) is capable of switching between a first position and a second position; the clutch member (161) is at the first position to connect the working shaft (130) and the rotating member (142), and the rotating member (142) rotates to drive the working shaft (130) to continuously rotate; the clutch member is at the second position, and is disconnected from at least one of the working shaft (130) and the rotating member (142), and the rotating member (142) rotates to drive the working shaft (130) to intermittently rotate; the clutch position of the clutch member (161) is at the side of the hydraulic impact unit (140) distant from the motor. Only the sealing between one end of the rotating member (142) and the working shaft (130) needs to be considered, and the sealing between the hydraulic impact unit (140) and the working shaft (130) can be ensured.
