The hand-held paper puncher with this structure has the advantages of small size, simple structure, and convenient use. It can be carried out and punched paper at any place and time. It is very useful for organizing materials and binding documents. With a suitable tool, it can also punch holes in thin rubber sheets, plastic sheets and other materials, which provides great convenience for users.

Description

A hand-held paper hole punch

technical field

The utility model relates to an appliance for punching holes on paper, which belongs to the technical field of stationery.

Background technique

Punching holes on paper is often needed in copywriting work, such as binding documents, materials, etc., generally use a puncher, the puncher is based on the principle of leverage, the handle is pressed down, and the handle drives the punching rod on the paper The upper hole is punched, and the front end of the push rod has a hollow circular blade. This hole punch is easy to use and is especially suitable for a small amount of paper punching work in offices and other places. However, this hole punch has structures such as a chassis, a support, and a handle, which takes up a large space and cannot be carried outside, which limits its use place and use time.

Utility model content

The technical problem to be solved by the utility model is to provide a hand-held paper hole puncher with simple structure, small volume and portable.

The technical scheme that solves the above-mentioned technical problem is:

A hand-held paper hole puncher, which consists of a handle and a push rod. The push rod is a cylindrical metal rod fixedly mounted on the front end of the handle. There is a paper scrap groove on the side wall, and the paper dust groove communicates with the hollow cavity of the annular blade.

In the above-mentioned hand-held paper puncher, the outer diameter of the annular blade has a taper, and the outer circumference of the annular blade is threaded.

The above-mentioned hand-held paper puncher, the length of the ejector pin is 80-100mm, the diameter of the ejector pin is 4-6mm, the diameter of the front edge of the annular blade is 3-4mm, the length of the annular blade is 4-6mm, paper scraps The length of the groove is 12-16mm.

The hand-held paper puncher with this structure has the advantages of small size, simple structure, and convenient use. It can be carried out and punched paper at any place and time. It is very suitable for organizing materials and binding documents. It can also punch holes in thin rubber sheets, plastic sheets and other materials, which provides great convenience for users.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is A-A sectional view.

The markings in the figure are as follows: handle 1, ejector rod 2, annular blade 3, paper waste trough 4.

Detailed ways

Shown in the figure, the utility model is made up of handle 1, push rod 2.

The push rod 2 is a cylindrical metal rod fixedly mounted on the front end of the handle 1, and the front end of the push rod 2 has a hollow annular blade 3. The outer diameter of annular blade 3 has a taper, and its rear end is equal to the diameter of push rod 2, and the diameter of its front end is less than the diameter of push rod 2, and the inner diameter of the hollow cavity of annular blade 3 is equal before and after, so that the cutting edge of annular blade 3 Form a sharp circular ring-shaped blade.

On the side wall of the ejector rod 2 at the rear of the annular blade 3, a paper dust groove 4 is opened, and the paper dust groove 4 communicates with the hollow cavity of the annular blade 3. The function of the scrap chute 4 is: the circular scraps cut off by the annular blade 3 enter the hollow cavity of the annular blade 3, and then are discharged from the scrap chute 4 connected by the hollow cavity to the outside.

In order to be more convenient for punching, especially punching holes on thicker rubber and plastic sheets is more labor-saving, and the outer circumference of the annular blade 3 can also be processed with threads.

The size of an embodiment of the present utility model is:

The length of the ejector pin is 80mm, the diameter of the ejector pin is 6mm, the diameter of the front edge of the annular blade is 4mm, the length of the annular blade is 5mm, and the length of the paper scrap groove is 14mm.
