[0002] Patent document CN221284827U discloses a magnetic snap fastener, which includes a male snap fastener and a female snap fastener. A slot is formed on one side of the female snap fastener, and a connecting post is fixedly installed on one side of the male snap fastener. A locking block is fixedly installed at one end of the connecting post, and the surface of the locking block engages with the inner wall of the slot. An installation cavity is formed inside the female snap fastener, and a locking assembly for engaging and fixing the locking block into the slot cavity is installed inside the installation cavity. The locking assembly fixes the position of the female snap fastener. The male snap fastener can be locked onto the female snap fastener through the locking assembly. A magnetic component is provided between the locking block and the slot, which can cooperate with the locking assembly to lock and fix the male snap fastener onto the female snap fastener. However, this magnetic snap fastener is prone to slippage under lateral pushing force during use, and the magnetic force of the magnet is not concentrated, resulting in a loose engagement. Furthermore, the outer shell of this magnetic snap fastener is made of metal sheet, making it prone to surface scratches during use and rust formation between adjacent metal components, affecting its aesthetics and service life. Therefore, it is necessary to optimize the structure of this magnetic snap to overcome the above-mentioned defects. Utility Model Content
