The electronic locks in the prior art are electronic components that realize the electric control function in the lock body, and the locking and unlocking actions of the oblique tongue and the square tongue in the lock body can be controlled and triggered by the electronic components, and then the extended functions such as escape locks are realized through the internal mechanical parts. Due to the assembly position arrangement of the internal mechanical parts and components of the electronic locks on the market, the movement of the lock tongue cannot be directly detected by the corresponding sensor. It is necessary to transmit the movement of the lock tongue to the sensor through additional parts to trigger the electronic lock to realize the automatic locking and unlocking function. The traditional method is to add a sliding rod between the square tongue and the sensor inside the lock body. The sliding rod moves after contacting the rotated square tongue and collides with the sensor to trigger the automatic driving function of the lock body. The sliding rod uses a spring to realize the reset function. This structure requires a large installation and movement space to be reserved inside the lock body, which makes the volume of the lock body too large, affecting the applicability of the lock body; at the same time, the structure of the sliding rod has the problem of getting stuck or not sliding in place during the sliding process, affecting the use effect of the lock body; and in traditional electronic locks, the sensor is fixed on the circuit board by the cooperation between the screws / nuts, and the positional relationship between the sensor and the trigger parts and components cannot be adjusted. Different sensors will produce signal tolerances due to the manufacturing or assembly errors of the trigger parts and components, which makes the electronic lock hysteresis when working.

Different from the prior art, which uses a sliding rod that slides horizontally or vertically as a component of the trigger sensor, in the present invention, the shift member 9 is connected to the lock housing 1 by rotation, and the magnetic connection between the magnetic link 10 and the square hole pull shaft 4 is used to make the shift member 9 rotate with the square hole pull shaft 4. In the case of the present invention, when the square hole pull shaft 4 rotates upward, the magnetic link 10 is pushed upward and rotates clockwise. At this time, the trigger rod 11 swings toward the sensor 6 and squeezes the elastic lever 12 to trigger the sensor 6.
