ABSTRACT:
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to a locking device for the trigger of a pistol, and in particular, relates to a locking device comprising a first and a second clipping seat to mount the trigger and the trigger guard of a pistol, such that the trigger cannot be operated unless the locking device is unlocked.
b) Description of the Prior Art
ROC patent publication no. 272 628 entitled “locking apparatus for trigger” relates to a locking apparatus comprising a fixing seat and an engaging seat. A cover is used to covers the fixing seat, and a pad is provided to one edge of the fixing seat. The engaging seat, adjacent to the fixing seat, is also provided with a pad, characterized in that a locking core is provided to the fixing seat and forms integrally with a combination shaft as one unit. One lateral edge of the combination shaft is provided with a ratchet face and the combination shaft can be inserted into a recess within the engaging seat, and the ratchet face is in engagement with the ratchet face of the stopping block of the engaging seat. This provides a locking to the trigger. When the two ratchet faces are separated, it is at a unlocking position.
The drawback of the above locking apparatus is that a key is needed to insert into the locking core to rotate the combination shaft so that the two ratchet face will separate from each other. If the key is unavailable or lost, the trigger cannot be operated. Another disadvantage is that a locksmith has to be hired to unlock the locking apparatus. Thus, it incurs expenses for such an operation.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a locking device for the trigger of a pistol comprising a first and a second clipping seat, wherein the first clipping seat is provided with a hollow slot having a stopping block mounted with a plurality of ratchet wheels, the second clipping seat is provided with a locking seat and a geared-shaft slot, and a number combination locker is provided to the locking seat, a geared-shaft is provided to the geared-shaft slot and is mounted with a plurality of ratchet wheels, and the geared-shaft is adapted for the hollow slot, characterized in that a cut face is provided to the circular end of the geared-shaft and the top face of the geared-shaft is provided with a rotating button, and when the cut face is restricted by the control board of the number combination locker, the geared-shaft cannot be rotated and the trigger is at the locking position, and when the number wheels of the number combination locker is rotated to a correct number, the control board is free to retract and the cut face of the geared-shaft is not engaged with the control board, the geared-shaft is free to rotate, and the ratchet wheel of the geared-shaft and the ratchet wheel (
42
) with the stopping block (
17
) are thus disengaged, and the trigger is at the unlocking position.
It is yet another object of the present invention to provide a locking device for the trigger of the pistol, wherein the combination numeral of the number combination locker to unlock the locking device can be re-adjusted or re-set.
