Product Name: Acoustic Magnetic Hammer

The principle of Nanjing Rich Electronics' acoustic magnetic small hammer is composed of a steel needle, a plastic shell, and a lock core. The lock core is actually a simple device formed by three steel balls, a steel ring, and a spring. The steel balls are normally in a closed state under the thrust of the spring. When the steel needle is inserted, the steel ball is tightly fastened in the gap of the steel needle. The opening of this acoustic magnetic small hammer mainly relies on the magnetic steel of more than 12000GS to suck the three steel balls that are stuck in the steel needle out of the lock core, and the steel needle can be smoothly pulled out from the magnetic buckle. Magnetic steel with a size of over 12000GS and magnetic properties is a commonly used strong magnetic tool by cashiers. Most supermarkets use this button to effectively prevent theft of goods.
