[0002] An air compressor is a device used to compress gas. An air compressor is similar in construction to a water pump. Most air compressors are reciprocating piston, rotary vane or rotary screw.

[0003] At present, when most air compressors are in use, their piston parts are driven by a drive mechanism installed outside to work with a pulley to compress the air. However, since the pulley is directly exposed to the outside world when running at high speed, the existing protection structure is to set a wrapped outer frame at the pulley for protection. However, if the pulley assembly is offset or has other problems, it is inconvenient to disassemble and install the outer frame, and its protection range is small, and it is impossible to protect the external piston assembly and the drive mechanism at the same time, and the protection effect is poor. Therefore, it is necessary to design a gas compressor safety protection device that is easy to install and disassemble and has good protection effect to solve the above problems.
