Press, the lock is mounted on the door panel to lock the door panel, which is a necessary device for indoor security protection. The common lock form is a manual mode operator including a combination of an external lock, an internal lock and a lock bolt, which is often unable to be correctly inserted in a dimly lit place, and is inconvenient due to the time and place.

The automatically controlled motor-type electronic lock, because the stroke of the tongue is electronically controlled, and is a fixed trajectory, without the above-mentioned manual lock problem. When the motor type electronic lock is used for the door lock, it is usually embedded in the door panel, and an opening for the lock tongue is opened at the corresponding lock hole to fix the lock tongue and the lock hole.

However, when the above-mentioned motor-type electronic lock is used, the following problems and defects are indeed to be improved:

First, the power source of the locking tongue for telescopic movement is generally the screw driven by the motor. When the motor rotates, the screw gradually expands and protrudes, and slowly pushes the locking tongue outward. In this push action, it is necessary to provide the space required for the screw extension stroke, so that the space in which the lock specific product can be reduced is limited, but the space usually has no other effect and is very wasteful of space.

Second, the motor of the lock can only push the lock tongue, so it is generally a low-power motor, in other words, its rotation speed is slow, and the pitch of the motor screw used for the small-volume lock is also small, so that the motor needs to be rotated for at least several seconds to complete. The bolt is pushed out so that the unlocking action is very slow.
