Steering wheel lock

A steering wheel lock comprises a lock mount 2, a retaining rod 3, a combination lock 4, a lock knob 5, a lock sleeve 6, a retractable rod 7 and a pin set 8. The double locking function provided by the combination lock 4 and the lock knob 5 makes decoding much more difficult. It is an additional locking mechanism that the pin set 8 composed of a long pin 80 and two short pins 81,82 can be inserted into pin holes 412, 422, 442, 452 within the combination lock. An extra code set specifying the alignment configuration of the pin holes 412, 422, 432, 442, 452 is then needed to open the lock.
