Abstract
Discloses are a power tool and a clutch assembly. The power tool includes a housing; a motor; and a transmission assembly, driven by the motor and including a clutch assembly. The clutch assembly includes an intermediate shaft, and an elastic member and a clutch block that are sleeved on the intermediate shaft. A front end of the elastic member is supported on the intermediate shaft, and a rear end of the elastic member is supported on the clutch block. The clutch block includes: a gear; a friction plate; and a nut. The gear rotates relative to the friction plate and the nut, in response to a driving force of the motor for driving the gear being greater than a sum of a friction force between the gear and the friction plate and a friction force between the gear and the nut.
