Abstract: A multi-stage motorcycle lock includes a locking seat, a guide rod, a combination lock with numbers thereon, a retaining seat, a stopper, a protecting sleeve, a telescopic rod, a stud lock rod, etc. Each of plurality of eccentric holes of the combination lock is formed with a confining ring, and the locking means of the telescopic rod is eccentric. The eccentric design causes that the lock only has only correct number. The eccentric holes are rotated through 180 degrees, the locking means of the telescopic rod is stopped by the confining rings of the combination lock so that the telescopic rod can not protrude out or reduce inwards. Thereby, the effect of burglar-proof is achieved. There are two locking stages so as to have a preferred burglar-proof is achieved. The locking and unlocking of the present invention are not performed by using any key. Thus the operation is convenient.

Abstract: A steering wheel lock comprises a lock mount, a retaining rod, a combination lock, a lock knob, a lock sleeve, a retractable rod and a pin set. The double locking function provided by the combination lock and the lock knob makes decoding much more difficult. It is an additional locking mechanism that a pin set composed of a long pin and two short pins can be inserted into the pin holes within the combination lock. An extra code set specifying the alignment configuration of the pin holes is then needed to open the lock.
