The invention relates to a file threading device for human resource management, which comprises a device body and a partition plate fixedly mounted on the device body, and further comprises an air cylinder and an ejector pin mechanism, the air cylinder comprises an outer cylinder and a piston rod sleeved with the air cylinder, and the outer cylinder is communicated with the ejector pin mechanism through an air pipe and a flow divider; the gas compression cylinder is formed by the outer cylinder and the piston rod and is connected with other ejector pin mechanisms through the gas pipe and the flow divider, through compressed gas in the gas cylinder, after the ejector pin mechanisms complete perforating of files, the vent hole descends to coincide with the through hole of the relay sleeve, and the file perforating efficiency is improved. High-pressure gas accumulated in the outer cylinder originally is instantly released into the ejector pin through the relay sleeve and the vent hole and is sprayed out from the
