Lock assembly for gear shifter
 A lock assembly for a gear shifter of a vehicle includes a base plate mounted to a floor of the vehicle adjacent to the gear shifter, a base frame mounted on the base plate, and a motor mounted on the base frame and having an output bevel gear. A pair of mount plates are spaced on the base frame. A hollow holder is movably mounted on two guiding bars which parallelly extend between the mount plates. A holder block is provided inside the hollow holder. A guiding sleeve mounted on the base plate receives a screw therein. An end of the screw extends out of the guiding sleeve and engages with a holder for securely holding the gear shifter and for moving therewith. A screw member is rotatably mounted in one of the mount plates. The screw member includes a bevel gear end which meshes with the bevel gear of the motor, a right hand thread portion which engages with the hollow holder, and a left hand thread portion which engages with the holder block. A housing is provided to enclose the lock assembly and has an opening through which the gear shifter passes. The screw is locked between the hollow holder and the holder block when the motor is activated to turn in one direction. The screw is unlocked when the motor is activated to turn in another direction.
