Abstract
An electric hammer includes a housing, an electric motor, an output assembly, an impact assembly, a mounting shaft, a clutch assembly, and a switching assembly. The mounting shaft is rotatable about a second axis. When the electric hammer is in the drill mode, a sleeve of the output assembly rotates. When the electric hammer is in the hammer drill mode, the sleeve rotates and an impact block of the impact assembly reciprocates in the sleeve. The switching assembly is configured to switch the clutch assembly between a first state and a second state and includes a switching element. The switching element includes a forced end and a drive end, the output assembly moving along a first axis drives the forced end to move, and the drive end is configured to drive the clutch assembly to be switched to the first state.
