Referring to fig. 5 to 9, a magnetic lock according to the second embodiment of the present invention includes a pressing plate 201, a locking member 202, a bearing member 206, a first rotating shaft 203, a locking pin 204, and an elastic member 205. The bearing member 206 is provided with a first shaft hole 207, the pressing plate 201 is provided with a second shaft hole 212, and the first rotating shaft 203 penetrates through the first shaft hole 207 and the second shaft hole 212 at the same time, so that the pressing plate 201 can rotate by taking the first rotating shaft 203 as a rotation center. The carrier 206 has a receiving groove 208 formed on one side wall thereof. The pressing plate 201 is provided with a first through hole 211, and the lock pin 204 penetrates through the first through hole 211. The elastic member 205 abuts against the other side wall of the carrier 206 and the lock pin 204, so that the lock pin 204 is accommodated in the accommodating groove 208 in the locked state. The locking member 202 is fixedly connected to the bottom surface of the pressing plate 201 through one end thereof, so that when the pressing plate 201 is in the locking position, a gap between the bottom end of the locking member 202 and the bottom surface of the bearing 206 can accommodate a component to be locked. The lock pin 204 is made of a material with magnetic attraction property.

Wherein, the tail end 245 of the pressing plate 201 is a semi-cylindrical surface. In this case, the rear-end engagement piece 235 is in smooth contact with the rear end 245 of the pressure plate 201 both in the process of applying the force to temporarily lock the accommodating piece 238 with the pressure plate 201 and in the process of applying the force to disassemble the temporary lock between the accommodating piece 238 and the pressure plate 201, so that the smoothness in the force application process can be increased and the service life of the accommodating piece 238 can be prolonged.

In addition, the first aperture 246 can be formed between the upper contact surface 243 of the first rib 232 and the upper panel 234 through smooth transition, and the second aperture 247 can be formed between the tail end 245 of the pressing plate 201 and the upper panel 234 through the semi-cylindrical surface, so that the problem that the temporary locking between the accommodating member 238 and the pressing plate 201 is difficult to disassemble due to excessively dense negative pressure can be avoided.

Wherein the magnetic pole and the accommodating piece are integrated into a whole. In this case, the unlocking key does not cause the parts to be discarded due to the separation between the magnetic pole and the housing 238. In this embodiment, the magnetic poles are disposed in the magnetic pole packet 248 on the right side of the receiving member 238, and the magnetic pole packet 248 is fixedly connected to the receiving member 238.
