ABSTRACT:
A locking device having a tubular body, in which a stationary nut member is fixed and a lead screw is threadedly engaged with and through the stationary nut member. A lock nut member is threadedly engaged about the lead screw and biased by a biasing element to a frictional contact with the stationary nut member, so that a friction is caused between those two nut members, thereby preventing a relative threaded movement between the lead screw and the stationary nut member and thus normally setting this locking device in a locked state. The lock nut member may be rotated by an operation element about the lead screw against the biasing element so as to bring the lock nut member itself out of contact with the stationary nut member, thereby allowing the relative threaded movement between the lead screw and stationary lock member for an unlocking purpose.
