Clutch device for hand held electric hammer

The utility model relates to a clutch device for a hand-held electric hammer to make the hand-held electric hammer have the function of an electric chisel. The clutch device comprises a gas cylinder, a bevel gear wheel sheathed on the gas cylinder and capable of sliding along axial direction, a propping and pushing mechanism and a fixed block. A spring which can drives the bevel gear wheel to demesh from a driving bevel gear wheel is sheathed on the gas cylinder on the plane position of the bevel gear wheel, and the propping and pushing mechanism is a rotary type slope structure. The propping and pushing mechanism drives the bevel gear wheel to move axially by utilizing inclined-plane motion generated in rotation; when the bevel gear wheel is engaged with the driving bevel gear wheel, the electric hammer is in operating state; when the bevel gear wheel and the driving bevel gear wheel are demeshed from each other under the action of a spring force, the electric hammer operates to play the function of an electric chisel.
