Locking structure for an automobile transmission shift lever

A locking structure for locking a transmission shift lever of an automobile, comprising:

• a base member having a central through hole and a concave slot formed therein, mounted to an upper end of the shift lever in a relatively movable manner by having the upper end extending through the central hole of the base member, the upper end of the shift lever that extends through the central hole of the base member comprising a upper truncated-conic portion and a circumferential groove formed thereon below the truncated-conic portion;
• a cover member secured to the base member by fastening means to define therebetween a space, the cover member having a first channel and a second channel formed therein;
• a locking driver received in the first channel of the cover member, having a rotatable driving rod securely connected on the front end of the locking driver, the rotatable driving rod being rotatable by a key through the locking driver;
• a driving member having a through hole connected to the driving rod of the locking driver, the driving member being arranged above the concave slot of the base member so that the driving member may be rotatable by the key via the driving rod;
• a biasing spring positioned on one end of the concave slot of the base member;
• a hook member adapted to lock the shift lever at the circumferential groove or unlock the shift lever, controlled by the driving member;
• and
• a shift enabling button, in the form of an elongated bar, movably received within the second channel with an outer end thereof exposed outside the second channel of the cover member, the enabling button having a slot adapted to receive therein the upper end of the shift lever, the button slot having formed therein at a lower portion thereof an inclined surface to be in contact and engagement with the truncated-conic portion of the shift lever so that by moving the shift enabling button toward the second channel of the cover member, the engagement forces the shift lever downward to further allow the shift lever to switch to a different position when the driving member is at an unlocked position.
