Specifically, the transverse pin 31 drives the positioning pin 33 to move through the protruding portion 311.

Optionally, the holding space 322 is a first groove structure or a first hole structure.

Alternatively, relief space 321 is a second slot structure or a second aperture structure.

By providing the holding space 322 and the relief space 321 in a groove structure or a hole structure, it is possible to reduce resistance generated during operation and to make the movement of the horizontal pin 31 and the vertical pin 32 with the positioning pin 33 smoother.

Specifically, the holding space 322 and the relief space 321 are located on both sides of the axial plane of the vertical pin 32, respectively. By this arrangement, the spatial layout inside the lock body 10 can be set appropriately, and thus the positioning pin 33 can be driven easily by the cross pin 31 in the course of the positional change.

As shown in fig. 1 to 7, the locking assembly 30 further has a plurality of restoring members 34, and the restoring members 34 corresponding to the transverse pin 31, the positioning pin 33 and the vertical pin 32 are respectively provided with the restoring members 34, and the restoring members 34 corresponding to the transverse pin 31 provide restoring forces to the transverse pin 31 extending into the mounting holes 11 of the first locking groove 41 and the second locking groove 42, the restoring members 34 corresponding to the vertical pin 32 provide restoring forces to the vertical pin 32 moving to the lock cylinder assembly 20 side, and the restoring members 34 corresponding to the positioning pin 33 provide restoring forces to the positioning pin 33 moving to the vertical pin 32 side.
