The combination lock has a toothed combination wheel, and three-way locking means (2) formed with the shaft of the combination lock. A three-extension key (3) corresponds to the key hole of the locking means and a rear locking pin normally pokes into the rear portion of the key hole of the locking means. The combination lock is derived from a conventional combination lock, which comprises a rotating knob (11), a dial (12) and a fixing disc (13). The rotating knob and dial are fixed to the pin tumbler cylinder (21) of the locking means. The lock is coaxially formed with three combination wheel (14-16), each wheel being respectively formed with a slot (14a-16a) thereon so as to be lined up for opening as it is engaged with a latch (17) inter-related to the safe handle. |
