Do you know the structure of the well-known nail shooter?

Nail loading structure

The buttstock uses a more common nail-shooting device. The nails are pasted side by side on a long strip. This is a nail belt installed in the magazine, which can transport bullets to the "barrel". The spring at the bottom of the magazine pushes the stapler strap into the barrel. When the hammer is lowered, the hammer will separate one of the nails so that the wood can be driven into the gun. When the hammer device returns to the top, the spring pushes the next nail into position.

One of the advantages of this system is that the glue helps fix the nails. When nailing in wood, strong friction heats the glue to its melting point. When the nails are in place, the glue quickly hardens and will soon merge into the surrounding wood.

For this nail gun , the motor is only to pull the nail gun, and the real hammering work is done by the coil spring.

The spiral tube is a very reliable hammering device. The spiral tube is a very simple electromagnet, which is widely used in various machinery.

If you have read the working principle of electromagnets, you will know the basic principle of electromagnetic equipment: electromagnetic waves generate magnetic fields around wires. Coiling up a live wire can increase the magnetic field. Just like a constant, the magnetic field of an electromagnet has polarity-a "north" pole and a "south" pole. If the two poles of the two magnets pointing to the north are close, they will repel each other; if the two magnets guide poles are close, they will also repel each other; but if the two magnets are pointed to the north and the two ends of the guide are close, they will repel each other. attract each other.

With an electromagnet, you can change the direction of the poles. Just change the direction of the current, and the north and south points of the electromagnet will change accordingly.

The spiral tube is an electromagnetic coil with a sliding piston inside. This piston is made of magnetic material in a nail gun. When the current flows in one direction, the electromagnetic field and the magnetic piston will repel each other and push each other. But when the direction of the current changes and the poles of the magnetic field are reversed, the electromagnetic field will pull the piston back. Some spiral tubes pull the piston back through a spring device.
