Automobile gear shiftlever lock

A gear shift lock for a gear shiftlever of an automobile with a manual transmission, the gear shift lock comprising:

• a gear shiftlever seat (10) for securely receiving the gear shiftlever (11) therein so as to allow the gear shiftlever (11) to extend out therefrom;
• a strike plate ring (20) firmly mounted on top of the seat (10) and having a through hole (21) defined therethrough;
• a latch tube (30) with a flange (31) detachably engaged with a periphery defining the through hole (21) of the ring (20), a protrusion (32) formed beneath the flange (31) to be alternatively received in the through hole (21) and a shoulder (33) formed inside the tube (30);
• a spring (40) a first end of which is compressibly abutted to the shoulder (33) so as to alternatively push the tube (30);
• an adjustment ring (50) threadingly engaged with a top portion of the rube (30);
• a retaining tube (60) securely connected with a free end of the gear shiftlever (11) by inserting through the strike plate ring (20), the tube (30), the spring (40) and the adjustment ring (50) and abutted by a second end of the spring (40);
• wherein the retaining tube (60) has a pair of notches (61) diametrically defined in a top face thereof, a pair of diametrically defined L shaped slots (62) each being apart from either one of the notches (61) and a keyway (63) defined in an outer periphery thereof;
• a hollow core (70) securely engaged with the tube (30) and having the spring (40) and the retaining tube (60) movably received therein and having a keyhole (71) rotatably defined in a face (701) formed to close one end of the core (70), an extension (72) integrally rotatable with the keyhole (71) and having a pair of studs (721) diametrically protruding out therefrom to alternatively correspond between the pair of L shaped slots (62) and the notches (61), a pin (73) extending into the inside of the core (70) and corresponding to the keyway (63) of the retaining tube (60) and a pair of opposite bosses (74) symmetrically protruding out from the outer periphery thereof;
• a handle (80) having a path (81) defined to receive the core (70) therein and a pair of symmetrically defined tracks (82) in a face defining the path (81) to correspond to the pair of bosses (74);
• wherein the rotation of the keyhole (71) together with the extension (72) will allow the studs (721) to alternatively align between the notch (61) and the L shaped slots (62) and a lift movement of the handle (80) will move the studs (721) to the bottom of the L shaped slots (62) and the protrusion away from the through hole (21) of the strike plate ring (20) thereby allowing free movement of the gear shiftlever (11);
• wherein the rotation of the keyhole (71) will alternatively drive the studs (721) to be retained/free by the L shaped slots (62).
