ABSTRACT:
An automobile steering wheel lock consists of an elongated tube member, a housing, an elongated rod member and a lock mechanism. The improvement of the automobile steering wheel lock is in the lock mechanism which is inserted in a lower chamber of the housing. The lock mechanism is combined by a locking member, a sleeve, a bearing member and an actuator. The sleeve defining a hollow cylinder has a bottom groove mounted by a projection of the locking member. The bearing member having a bottom cylindrical projection retained by a powerful spring is capable of passing through the sleeve and being inserted in a central circular groove of the projection of the locking member. A plurality of lugs disposed on the external wall of the actuator and corresponding to a plurality of race ways in the internal wall of the sleeve are capable of being moved by following the curvy ways of the plurality of race ways when the actuator is pushed up or drawn down, by which the bearing member controlled by the actuator and the powerful spring will protrude into or be withdrawn from one of a plurality of annular grooves of the elongated rod member so as to lock or unlock the automobile steering wheel lock. Moreover, a locating member combined by a set pin and a spring and disposed in a pin hole of the rear portion of the elongated rod member may prevent the elongated rod member from being completely drawn out of the elongated tube member.
