Abstract
The toothed section of the sliding socket (5) is continuous. For uncoupling, the socket is moved in direction towards the eccentric sleeve (6). When uncoupled, a locking unit (17) on the sliding socket is in connection with a holder (18) on the connecting rod (7), so that the eccentric sleeve is held non-turnable relative to the connecting rod. The locking unit consists of a projection, and the holder consists of a recess, to accommodate it when the socket is in uncoupled position. The socket has an untoothed guide section (19) and the driver ring (13) has guide section (20).
