A punching machine comprises the followings: a main body(100) including a fixing unit(110) with a guide groove(111) formed vertically at a side, and an inserting unit(120) supporting a paper inserted; a punching unit(200) including a lifting unit(210) inserted between the fixing unit and the inserting unit to be lifted, with a guide protrusion(211) to closely contact the guide groove at a side, and a punching unit(220) located above the lifting unit, with more than one punching pin protruded downward to punch the paper inserted to the inserting unit; a drive unit(300) including a drive motor(310) moving the punching unit up and down to move the lifting unit and to punch more than one hole on the paper by lowering the punching pin from up to down; and a height adjusting unit(400) installed on the main body to adjust lifting height of the punching unit, including an adjusting plate, a support bolt, and a switch to stop the drive motor. |
