Although this technical scheme can realize two kinds of operation modes of key manual drive and motor automatic drive, the structure is more complicated, and this technical scheme realizes the transmission that in-process relates to between a plurality of spare parts for comparatively loaded down with trivial details when the lock body assembly, manufacturing cost is higher, and the lock body is bulky, and the suitability is not strong enough, in case breaks down, dismantles the maintenance more troublesome, and it is also inconvenient, laborsaving to use simultaneously.

In addition, in order to facilitate the user to quickly open the drawer after unlocking, a spring is usually arranged behind the drawer, so that the drawer automatically pops up after unlocking. The design increases the pretightening force applied to the lock tongue, if the motor torque is insufficient, the pretightening force applied to the lock tongue is too large to open the drawer, so that the service life of the motor is influenced, and higher requirements are put forward on the power of the driving motor.
