A locking cartridge is supported on the carriage of a linear movement unit, which carriage is movable and positionable on at least one guide rod. The locking cartridge contains two clamping members of identical construction which are oriented symmetrically to each other with respect to a plane perpendicular to the guide rod and which have head pieces seated on the guide rod, as well as cam surfaces facing away from said head pieces and serving for spreading the clamping members apart by means of a spreading pin so that the head pieces are clamped to the guide rod. The spreading pin is held by an annular sleeve surrounding the clamping members and acted upon by a pressure member against the bias of a coil spring. The pressure member is located at the bottom of a cylindrical casing into which a fluid line opens. |
