BACKGROUND

Staple guns are widely used in the decoration industry. Based on different driving sources, staple guns are divided into electric staple guns, pneumatic staple guns, gas-powered staple guns, manual staple guns, etc. The pneumatic staple guns and the electric staple guns use electric power or air compressors as power sources to drive striking pins in air cylinders of the staple guns to do striking motion to drive staples in a staple magazine into objects or shoot staples out. Although operations are easy, a fixed power supply or a set of air compressor equipment is required, which can consume more electric energy and is extremely unsafe and inconvenient because of a long power cord.
