A lock tongue opening 3 is formed at the front end of the lock case 1 for the magnetically attracted lock tongue 2 to extend out. A lock tongue plate 4 is connected to the rear end of the magnetically attracted lock tongue 2. A square core 5 is rotatably arranged inside the lock case 1. A lock tongue dial 6 is sleeved on the square core 5, and the lock tongue dial 6 rotates synchronously with the square core 5. A guiding wall 7 is provided on the lock tongue plate 4. The front end of the guiding wall 7 is provided with a V-shaped inclined guide surface 8 with an opening facing forward. The inclined guide surface includes two inclined guide sub-surfaces 9, and the two inclined guide sub-surfaces 9 are symmetrically arranged up and down; A dial protrusion 10 is fixed on the lock tongue dial 6, and the dial protrusion 10 abuts against the front end of the inclined guide surface 8.
[0035] By symmetrically arranging the two inclined guide sub-surfaces 9 up and down, the same unlocking function can be realized whether the lock tongue dial 6 is dialed up or down. Therefore, during installation, the up and down directions can be randomly selected for installation, and normal unlocking can be achieved, which is convenient for installation.
[0036] Both sides of the lock tongue plate 4 are in sliding fit with the two side walls of the lock case 1. Through the above settings, the structure of the lock body can be simplified, and there is no need to additionally provide a lateral movement guiding component for the lock tongue plate 4.
