A sheet punching machine assembly is provided to simplify the structure and simply adjust height of a punching needle, to simply and quickly adjust a hole die penetrated by the punching needle, to improve convenience by modifying the connecting structure of an air supply hose, and to thereby prevent the air supply hose from being separated and easily transfer a punching unit. In a sheet punching machine assembly(100), an adjusting unit comprises a fixing boss(130) fixed with a body(101,109) and penetrated by a moving rod to have a screw thread on the outer peripheral surface; a rubber ring combined at a random position of the screw thread; a hollow adjusting knob(150) screw-combined at the fixing boss and formed with a protrusion on the upper end of the inner surface to penetrate the moving rod; and a connecting bush supported on the protrusion of the adjusting knob to be combined with an end of the moving rod. The position of the adjusting knob is maintained by the rubber ring. |
