ABSTRACT:
A main shaft in this device may rotate reciprocatingly within a certain angle to make a row of punch blades up and down reciprocatingly, of which one end is set pivotally inside one end of an aligned manual shaft which is bearing a winding handle on the other end. And, both shafts may rotate separately or synchronously by removing/inserting a pin from/into the coaxial dual shaft. i.e., the main shaft can be driven by either electric motor or manpower to have the papers punched. The manual shaft is always driven by manpower to have the bindings opened so as to bind paper. This device has a margin guiding member to fix the papers in position before punching, and also has a binding size indicating member to quickly indicate the proper size
umber of bindings being needed.
