Abstract
A paper punch has an inner punch and an outer punch movably received with respect to each other. The outer punch has a first contour punch so as to be able to punch a hole in a piece of paper with the same contour as that of the first contour punch, and the inner punch has a second contour punch so as to punch a small hole in a piece of paper with the same contour as that of the second contour punch. Because the second contour punch moves first and the first and the second contour punches are placed concentrically, a piece of paper is then able to be punched twice by the first and the second contour punches to have an attractive shape.
Claims18
A paper punch comprising:
- a handle (10);
- a base (30) pivotally connected with the handle (10) and having a housing (320), a first hole (360) defined to communicate with the housing (320), a paper slot (38) defined to communicate with the first hole (360) and a bottom cover (35) connected with the base (30) and provided with a second hole (351) in communication with the first hole (360);
- a core (40) snugly received in the housing (320) and having a large housing (422), a paper slot (46) corresponding to the paper slot (38), an outer channel (48) defined to communicate with the large housing (422) and multiple protrusions (440) extending out from a bottom thereof;
- an outer punch (50) movably received in the large housing (422) and having a first contour punch (52) extendably and movably received in the large housing (422), an inner channel (520) defined to communicate with the outer channel (48) and a small housing (542);
- an inner punch (56) contacted by the handle (10) and movably received in the small housing (542) and having a second contour punch (560) extendably and movably received in the small housing (542), the inner channel (520) and the outer channel (48);
- an abutting member (70) movably received in the outer channel (48) of the core (40) and having an inner hole (76) corresponding to the outer channel (48) and the inner channel (520) thereby allowing the second contour punch (560) to extend therethrough;
- a supporting member (80) detachably connected with the core (40) and having the abutting member (70) received therebetween;
- and
- the second contour punch (560) being able to extend through the small housing (542), the inner channel (520), the large housing (422), the outer channel (48), the paper slot (46) and into the inner hole (76) while the first contour punch (52) being able to extend into the paper slot (46).
