In order to further improve the adsorption effect of the magnet 33 on the lock core 32, the size of the magnet 33 can be greater than the radial cross-sectional size of the lock hole 31, so that the magnet 33 can completely cover the lock hole 31. Further, in order to increase the smoothness of the lock core 32 sliding into the concave hole 11, the radial cross-sectional size of the lock hole 31 can be not greater than the radial cross-sectional size of the concave hole 11, so that the lock core 32 can smoothly slide into the concave hole 11 from the lock hole 31, thereby improving the unlocking effect.
[0032] Further, in order to improve the efficiency of unlocking, an anti-skid groove 14 can be arranged on the outer side of the base 1, the anti-skid groove 14 is an anti-skid groove or an anti-skid protrusion, and then when the user rotates the base 1, the anti-skid groove 14 can increase the friction with the fingers, so that the rotating operation is more efficient and convenient.
