Description

TECHNICAL FIELD

[0001] The utility model relates to paper punching tool technical field, more specifically, it is a paper punch. BACKGROUND

[0002] In the aspect of handmade, the fixing method of paper has always been an important consideration factor. Traditionally, most of the handmade books or DIY papers are fixed by adhesives, such as glue, double-sided tape, etc. However, with the pursuit of individualization, handmade traces and unique style, the traditional adhesion method gradually appears monotonous and lacks creativity.

[0003] In order to cater to this market demand, a new method of fixing paper by wire tying has emerged. This wire tying fixing method not only has heavy handmade traces and unique style, but also can effectively avoid the problem of page falling, thereby greatly improving the practicability and ornamental value of handmade books or DIY papers.

[0004] However, this fixing method needs to punch holes in the paper stack. The traditional sewing needle is small in diameter, which is not easy to punch holes in the paper and is not convenient to hold, which makes the handmade more difficult. In addition, there is a safety hazard in the process of threading the paper, because the small needle tip is easy to prick the fingers, which increases the risk of operation. SUMMARY

[0005] The utility model provides a paper punch, which can conveniently take out the punching needle from the paper stack and reduce the risk of production.

[0006] The above-mentioned purpose is realized by the following technical scheme:

[0007] A paper punch comprises a seat body, a mouth is arranged on the seat body, an elastic sheet is fixedly connected to the lower end of the seat body, a crack is arranged on the elastic sheet and located in the mouth, a clamping container is fixedly clamped by the elastic sheet in the crack, an elastic column is inserted into the clamping container, and an insertion slot is arranged in the elastic column.

[0008] The clamping container is U-shaped.

[0009] A flange is formed on the side of the top of the clamping container away from the elastic column in the radial direction.

[0010] An arc groove is formed at the corner of the bottom of the clamping container.

[0011] A limiting seat is fixedly connected to the upper end of the seat body, a straight piece and a punching needle are slidably connected to the limiting seat, and the top of the straight piece can press on the top of the punching needle.

[0012] The straight piece is cylindrical.

[0013] The punching needle is a cylindrical body with a needle tip at the bottom, or a cuboid with a blade at the bottom.

[0014] The upper side of the punching needle is provided with a threading hole.

[0015] The spacing of the threading hole gradually decreases from bottom to top.

[0016] The seat body is connected with a screw head through thread cooperation, and the screw head is located at the front side of the limiting seat.

[0017] The paper puncher has the beneficial effects that:

[0018] The position of the mouth is protruded from the desktop, and the bottom of the punching needle is received by the clamping container and the elastic column, so that the punching needle is still in the paper, and the static friction is large, the clamping container can be pinched, the elastic column is used to extrude the punching needle, the clamping of the punching needle is completed, the punching needle is pinched, and the punching needle is easily taken out from the paper stack.

[0027] The paper puncher combines Figures 1 to 6, including the seat body 1, the left rear side of the seat body 1 is provided with a longitudinally extending mouth 2, the seat body 1 is fixedly connected with an elastic sheet 3 made of silica gel material or rubber material through an adhesive, the elastic sheet 3 is provided with a split 4 located at the center of the mouth 2, a U-shaped clamping container 5 is inserted into the split 4 to expand the split 4, and the clamping container 5 is clamped by the elastic force of the elastic sheet 3. Preferably, the top of the clamping container 5 extends radially outward to form a flange 6, and the flange 6 is used to abut against the top of the elastic sheet 3. The clamping container 5 is inserted with an elastic column 8, the elastic column 8 is provided with a slot 9, the opening area of the slot 9 decreases from top to bottom, or a chamfered surface is formed at the top edge of the slot 9. The slot 9 is used for the insertion of a punching needle 12. In use, a stack of paper is placed on the seat body 1, the punching needle 12 carrying a wire material is inserted into the slot 9 from top to bottom through the stack of paper and into the mouth 2, and finally into the slot 9. The clamping container 5 is pinched with two fingers, so that the clamping container 5 is deformed, the opening of the clamping container 5 is reduced, the elastic column 8 made of rubber material is squeezed and shrunk, the elastic column 8 squeezes the punching needle 12, and the frictional force generated can carry the punching needle 12, so that pinching the clamping container 5 is equivalent to pinching the punching needle 12, so as to increase the force receiving area and facilitate the downward extraction of the punching needle 12 from the stack of paper. The size of the clamping container 5 and the flange 6 can be just matched with the mouth 2, or the clamping container 5 and the flange 6 form a circular shape, which is convenient for alignment with the center of the circular-shaped mouth 2.

[0028] Preferably, an arc slot 7 is formed at the bottom of the clamping container 5 and at the corner, so that the clamping container 5 is easily deformed by pinching to reduce the U-shaped opening.

[0029] In order to facilitate the punching needle 12 to penetrate the paper and enter the slot 9, the upper end of the seat body 1 is fixedly connected with a limiting seat 10, a straight piece 11 and the punching needle 12 are slidably connected on the limiting seat 10, so that the top of the straight piece 11 can press on the top of the punching needle 12, and after pressing the straight piece 11, the straight piece 11 pushes the punching needle 12 to penetrate the paper. When the punching needle 12 is a cuboid, it only has a longitudinal degree of freedom and is arranged directly above the slot 9, so that the punching needle 12 easily enters the slot 9 after descending.

[0030] The upper side of the punching needle 12 is provided with a threading hole 12a. The spacing of the threading hole 12a gradually decreases from bottom to top, so that the wire can be clamped at the top of the threading hole 12a.

[0031] Reference Figure 1 , 2 and 7, the seat body 1 is threadedly connected with a screw head 13, the screw head 13 is located on the front side of the limiting seat 10, the screw head 13 can be clamped on the desktop, i.e. the table top 14, in cooperation with the seat body 1, and the to-be-punched object 15 is a stack of paper.
