The at least one clutch element (130A, 130B) is constituted to operatively connect, in a clutched state, the driving rod (14) to the pusher device (12) for driving the pusher device (12) by the electric drive device (141). The clutching device (13) is actuatable to assume an unclutched state in which the operative connection between the driving rod (14) and the pusher device (12) is released. Herein the clutching device (13) comprises a lock element (19) for locking the at least one clutch element (130A, 130B) in the clutched state.
