Abstract
The invention relates to a lubricating structure for a head of a staple gun. The lubricating structure comprises a gun shell and an air cylinder disposed in the gun shell. An air storage chamber, corresponding to the periphery of the air cylinder, is arranged inside the gun shell. A pressure relief hole communicating the air storage chamber with the inside of the air cylinder is formed in the lower end of the air cylinder. An oil inlet is formed in the surface of the gun shell, with one end communicated with the air storage chamber and the other end connected with an automatic oil supply unit. Since the head of the staple gun is provided with the oil inlet communicated with the inner cavity of the air cylinder and connected with the automatic oil supply unit, the automatic oil supply unit is capable of providing lubricating oil to the inner cavity of the air cylinder automatically to keep the inner cavity of the air cylinder lubricated sufficiently, friction force is reduced effectively, heat generated from friction force is reduced greatly, and abrasion of parts inside the head is also reduced greatly.
