The handle 19 is installed just corresponding to the clearance opening 5, and the position of the handle 19 does not need to be moved back, and the base can be embedded in the door panel instead of being set on the outside of the lock body. This can reduce the exposed part of the base, or even achieve complete embedding, which is suitable for most door panels, does not require thickening the door panel, and reduces the difficulty of installation. The large-sized base and the small-sized base in this embodiment are relative, and are not limited to a certain range. There are mini base handles 19 on the market, and the corresponding base here is small in size. The other is the base in this application, which can be used as the base of a hidden handle 19, so that the handle 19 is stored in the base. At this time, the length and thickness of the base need to be increased. The corresponding base here is large in size. The large-sized base is not limited to the function of hiding the handle 19 mentioned in this embodiment, and this application is just an example.

[0027] The operating mechanism 4 includes an arc-shaped rack 6, a transmission gear 7 and a driven reset member 8 for linkage with the handle 19.

A clearance step 37 is formed between the lock frame 35 and the magnetic lock tongue 3 on one side facing the contact sensor 36. When the movable seat 2 is in the locked position, the contact sensor 36 corresponds to the position of the clearance step 37 and the contact sensor 36 does not contact the lock frame 35. When the magnetic lock tongue 3 is retracted into the lock shell 1, it just touches the contact sensor 36, which indicates that the magnetic lock tongue 3 is in an unlocked state. When the magnetic lock tongue 3 extends out of the lock shell 1, it is misaligned with the contact sensor 36. Since the clearance step 37 is set, the contact sensor 36 and the lock frame 35 are away from each other, which indicates that the magnetic lock tongue 3 is in a locked state. In this embodiment, a built-in circuit board (not shown in the figure) can be electrically connected to the contact sensor 36, an alarm module can be set on the circuit board, or communication between the circuit board and the mobile phone APP can be set, and the mobile phone APP can remotely know the current state.
