| description | The present invention belongs to the technical field of puncher, specifically involving EG-1680 Three hole electric puncher, including the base, punching device, rotating shaft and drive unit; there are at least 2 sets of said punching devices, including the support frame arranged on the base and the punching assembly that moves up and down along the said support frame; the said rotating shaft can be connected with the support frame through rotation; the rotating shaft is furnished with appropriate eccentric cams that drive the punching assembly to move up and down; the staggered arrangement of eccentric cams enables the punching assemblies to asynchronously move up and down during the rotation of rotating shaft; the said drive unit is designed to drive the rotating shaft to rotate; the asynchronous vertical motion of various punching assemblies helps to save labor, thereby alleviating the requirements for motor output power and gear strength; this product is compact in structure, easy to use, cost effective, and stable in function. |
