Description

Manual paper cutter

Technical Field

The utility model mainly relates to the field of paper cutting, in particular to a manual paper cutting machine.

Background

The cutter is a conventional product and is used to handle the paper cutting requirements at the end of printing. The cut paper is typically handled by a paper cutter. The operation of the paper cutter is simple, and the requirement on the environment is not high. Generally, a power supply is adopted in a common office to guarantee that the work can be carried out by supplying power. However, the electric cutter needs to be energized, and is inconvenient to carry. For some small cuts, such laborious cutting is not required.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a manual paper cutter which comprises a rotary cutter 1 and a cutter body 2, wherein a rotary structure is arranged in the cutter body 2 and is connected with the cutter 1;

the rotating structure comprises a driving gear 5, the driving gear 5 is meshed with a rack 4, a pushing handle 3 is arranged at the bottom of the rack 4, the pushing handle 3 is pushed to drive the rack 4 to slide back and forth, the driving gear 5 is meshed with a driving wheel on a first rotating shaft 6, a driven wheel of the first rotating shaft 6 is meshed with a driving wheel of a second rotating shaft 7, a driven wheel of the second rotating shaft 7 is meshed with a driving wheel of a third rotating shaft 8, a helical gear 9 is arranged at the other end of the third rotating shaft 8, the helical gear 9 is meshed with a second helical gear 10, and the second helical gear 10 is connected with a cutter 1 through a rotating shaft.

Preferably, the first rotating shaft 6, the second rotating shaft 7, and the third rotating shaft 8 are sequentially fixed to two fixing blocks in the machine body 2.

Preferably, one end of the rack 4 is fixed on the machine body 2 through a spring. When the push handle 3 pushes the rack to move, the rack rebounds to the original position when the push handle 3 is not acted.

Preferably, all the driven wheels and the driving wheels have the same structure and the same size.

Preferably, a through hole is formed in the back of the machine body 2 close to the rack 4, and the pushing handle 3 penetrates through the through hole and moves in the through hole.

The utility model has the beneficial effects that:

this simple structure, through setting up a plurality of rotation axes, the epaxial gear intermeshing of rotation increases the displacement of rack, increases the number of revolutions of cutter, carries out the rotary cutting to the paper, is applicable to tailorring of small batch volume paper.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.

As shown in fig. 1-2, the present invention includes:

a manual paper cutter comprises a rotary cutter 1 and a machine body 2, wherein a rotary structure is arranged in the machine body 2 and is connected with the cutter 1;

the rotating structure comprises a driving gear 5, the driving gear 5 is meshed with a rack 4, a pushing handle 3 is arranged at the bottom of the rack 4, the pushing handle 3 is pushed to drive the rack 4 to slide back and forth, the driving gear 5 is meshed with a driving wheel on a first rotating shaft 6, a driven wheel of the first rotating shaft 6 is meshed with a driving wheel of a second rotating shaft 7, a driven wheel of the second rotating shaft 7 is meshed with a driving wheel of a third rotating shaft 8, a helical gear 9 is arranged at the other end of the third rotating shaft 8, the helical gear 9 is meshed with a second helical gear 10, and the second helical gear 10 is connected with a cutter 1 through a rotating shaft. In this embodiment, all the driven wheels and the driving wheels have the same structure and the same size.

The first rotating shaft 6, the second rotating shaft 7 and the third rotating shaft 8 are sequentially fixed on two fixing blocks in the machine body 2. One end of the rack 4 is fixed on the machine body 2 through a spring. When the push handle 3 pushes the rack to move, the rack rebounds to the original position when the push handle 3 is not acted. The back of the machine body 2 close to the rack 4 is provided with a through hole, and the pushing handle 3 penetrates through the through hole and moves in the through hole.

When the paper cutting device is used, the pushing handle 3 is pushed, the pushing handle 3 drives the driving gear 5 to rotate, then the second bevel gear 10 is driven to rotate, and finally the cutter is driven to rotate to cut paper.

This simple structure, through setting up a plurality of rotation axes, the epaxial gear intermeshing of rotation increases the displacement of rack, increases the number of revolutions of cutter, carries out the rotation cutting to the paper.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
