ABSTRACT:
An adjusting device for a nail gun includes a magazine, a shaft, a disc feeder and a positioning assembly. The shaft is mounted in the magazine and has two sliding grooves longitudinally formed respectively in the shaft and multiple positioning recesses formed on the sliding grooves. The disc feeder includes a rotating disc and a sleeve mounted around the shaft and has two mounting holes each corresponding to a positioning recess. The positioning assembly includes a clamp and an E-clip having two stops. The clamp is mounted in the sleeve and has two clamping arms each having a boss. The stops are mounted respectively in the mounting holes, respectively abutting the clamping arms and held by the E-clip. Therefore the magazine can be adjusted in one direction at multiple stages by pulling up and in the other direction by pressing the clamp that releases the stops for easy adjustment.
