Therefore, the arrangement mode can drive the rotating shaft to rotate by the driving motor, further drive the rotating spring to compress or extend, and the rotating spring is fixed in the lock tongue cavity and can drive the lock tongue to move up and down along the axial direction of the rotating shaft.

Preferably, the rotary spring is selected to be bi-directional, i.e. the rotary spring a33 has a space between adjacent wires, and it is because of the space that the spring can be compressed, otherwise it cannot be compressed if there is no space.

Therefore, the type of the rotary spring and the space length of the lock tongue cavity can be reasonably selected according to the running distance range of the lock tongue.

Preferably, the rotating spring with no space between adjacent spring wires can be selected for practical use, in which case the rotating spring can only work in a stretched state, but only the magnitude of the stretching deformation is different. When the rotating spring is in a natural state, the rotating spring is just positioned at the lowest end position corresponding to the lock tongue, namely the locking position, the rotating motor drives the rotating shaft to rotate, so that the rotating spring can be stretched, and at the moment, the lock tongue moves upwards to unlock the lock. This application allows the rotating spring to be in a natural state at all times in the locked state, and to be in a stretched state at all times after unlocking, and the travel length of the bolt is equal to the maximum stretched length of the rotating spring. In practical application, the lock core in a common lock is in a locking state for a long time, so that the mode has the advantages that the rotating spring is in a natural state for a long time, the rotating spring is favorable for keeping good working characteristics, and the defect is that the running length of the lock tongue is limited.
