[0005] As a preferred embodiment of the above solution, the slot width decreases from far away from the cutter end to close to the cutter end.

[0006] As a preferred solution of the above solution, the slot includes a groove and a rectangular through hole, and the rectangular through hole is located at the center of the bottom surface of the groove and passes through the slider.

[0007] As a preferred solution of the above solution, a handle is provided on the upper end of the insert, and the handle matches the groove.

[0008] As a preferred solution of the above solution, a magnetic attraction sheet is provided on the lower end surface of the handheld portion and the bottom surface of the groove.

[0009] As a preferred solution of the above solution, the limit baffle is provided with a plurality of placement slots for inserting pieces, and the placement slots are provided with magnetic sheets.

[0010] As a preferred solution of the above solution, a scale is provided on the base.

[0011] As a preferred solution of the above solution, a locking nut is provided on the slider.

[0012] As a preferred embodiment of the above solution, each width change of the slot corresponds to a different paper specification.

[0013] The advantages of the utility model are that the slots with step-wise width changes are provided, and the limit baffle can be quickly moved to a specific paper specification in conjunction with the insert piece, without the need to compare the limit baffle and the scale, and the use is convenient.

[0017] The technical solution of the present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0018] Example:

[0019] This embodiment is a paper cutter, such as Figure 1 As shown, it includes a base 1, a cutter 2, a guide rail 3 and a limit baffle 6. The base 1 is provided with a scale, the cutter 2 is rotatably set on one side of the base 1, the guide rail 3 is fixedly set on the base 1, a slider 5 is slidably set on the guide rail 3, and a locking nut 7 is provided on the slider. The limit baffle 6 is connected to the slider 5, and a plurality of placement grooves 9 are provided on the limit baffle 6. Inserts are placed in the placement grooves 9. The guide rail 4 is provided with a slot 4 with a stepped width. The slot width decreases from the end away from the cutter to the end close to the cutter. The slider 5 is provided with a slot 8 for inserting the insert. The insert extends into the slot through the slot, and different inserts match the various widths of the slot.

[0020] The slot includes a groove and a rectangular through hole, wherein the rectangular through hole is located in the center of the bottom surface of the groove and passes through the slider. Figure 2 As shown, the upper end of the insert 11 is provided with a handle 10, which matches the groove and is a waisted cylindrical shape. The lower end of the handle and the bottom of the groove are provided with a magnetic sheet. The placement groove has the same structure as the slot and also has a magnetic sheet inside. The magnetic sheet can attract the insert to the placement groove or slot to prevent it from falling.

[0021] Each width change in the slot corresponds to a different paper size. In this embodiment, the slot width changes in four steps, and each step from left to right corresponds to paper sizes of B5, A5, B6, and B7, respectively. Correspondingly, four inserts are provided, each corresponding to paper sizes of B5, A5, B6, and B7, and the width of each insert matches the four widths of the slot. For example, when you need to cut out A5-sized paper, you only need to insert the insert corresponding to A5 into the slot, and then translate the slider from left to right. When the slider moves to the slot corresponding to A5, the slider cannot continue to move right due to the presence of the insert. At this time, the edge of the limit block is aligned with the A5 scale on the base, achieving quick alignment and convenient operation. When you need to cut out paper sizes other than B5, A5, B6, and B7, do not insert the insert into the slot and operate it according to traditional paper cutter. The paper cutter in this embodiment is capable of quickly moving the limit baffle to a specific paper specification by setting slots with step-wise width changes in conjunction with the insert, and can conveniently cut out paper of specific commonly used specifications.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
