Protection structure for quickly connecting and inserting treatment head bayonet socket

The protection structure comprises the bayonet socket located on main equipment, a window is formed in the position, corresponding to the bayonet socket, of a machine shell, a guide rail in the vertical direction is fixedly arranged on the machine shell, a baffle is installed on the guide rail in a vertical sliding mode, and an electromagnet is fixedly installed on the position, above the baffle, of the machine shell. A limiting contact is fixedly connected or integrally arranged on a push rod of the electromagnet, a limiting hole matched with the limiting contact is formed in the baffle, an electromagnetic suction cup is fixedly installed above the electromagnet, and when the limiting contact is located in the limiting hole, the electromagnetic suction cup is powered on, and the baffle can be attracted to the electromagnetic suction cup. Power sources of the electromagnetic attraction head and the electromagnet are connected to a direct-current power supply of the main body equipment, and the positive electr
