Mounting structure for staple guns

摘要

An improved mounting structure for staple guns includes a plastic sleeve fitted around a cylinder of the staple gun for dividing an air chamber into an upper air chamber and a lower chamber. The plastic sleeve is comprised of a metal plate and a plastic body and may be fitted between two raised rings on the cylinder. Due to the plasticity of the plastic sleeve, the plastic sleeve may firmly adhere to the inner wall of the air chamber and the cylinder may be firmly positioned therein.
