When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When the number of an element is referred to as "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0026] like Figure 1-4 As shown, in the present embodiment, a safety paper cutter and its soft PVC pad are provided, including a sliding plate 2, a buckle seat 3, a pressing shell 1 and a circular cutter 4. The pressing shell 1 is elastically connected to the buckle seat 3. When the pressing shell 1 is pressed down, the circular cutter 4 will move downward at the same time. The buckle seat 3 is slidably connected to the sliding plate 2. A pair of reverse buckle seats 9 are arranged on the buckle seat 3 to limit the direction in which the pressing shell 1 slides on it. The pressing shell 1 is covered on the buckle seat 3, specifically half-covering the upper part and the side of the buckle seat 3. The circular cutter 4 is fixedly connected to the inner side wall of the pressing shell 1, and the circular cutter 4 abuts against the extended edge of the sliding plate 2, so that the circular cutter 4 can ensure cutting in a straight line when cutting, and can accurately align the position to be cut when cutting paper.

[0027] In this embodiment, the sliding plate 2 is further provided with a plurality of through holes 5, and these through holes 5 are all in different shapes. Because sometimes the sliding plate 2 needs to be used as a ruler, when the user needs to draw shapes on paper, he can draw according to the shapes of the through holes 5.

[0028] In this embodiment, the sliding plate 2 is provided with an integrally formed buckling strip 6 extending upward, the buckling seat 3 is buckled on the buckling strip 6, and the buckling seat 3 is slidingly connected to the sliding plate 2 through the buckling strip 6. Both sides of the buckling strip 6 are symmetrically provided with inwardly recessed sliding grooves so that the buckling seat 3 can rely on the sliding grooves to move horizontally.

[0029] In this embodiment, a pair of spring limiting columns 8 are integrally formed and extended downward at the top of the inner wall of the pressing housing 1, and the pair of spring limiting columns 8 are sleeved with springs 7. The buckle seat 3 is extended upward to form a pair of reverse buckle seats 9. The bottom of the spring limiting column 8 is threadedly connected with a bolt 12 for abutting against the inner wall of the top of the reverse buckle seat 9. The spring limiting column 8 passes through the reverse buckle seat 9 and is slidably connected to the reverse buckle seat 9. The two ends of the spring 7 are respectively abutted against the inner wall of the pressing housing 1 and the top side wall of the reverse buckle seat 9. When the pressing housing 1 is pressed, the spring 7 will be compressed, and when no pressure is applied, the spring 7 will recover and make the pressing housing 1 move upward to achieve the effect of resetting.

[0030] In this embodiment, the buckle seat 3 is provided with an integrally formed cutter guard plate 11 extending outwardly. The cutter guard plate 11 is used to provide protection for the cutter to prevent the circular cutter 4 from being scratched by the outside when not in use. It is worth mentioning that when there is no need to cut paper, the circular cutter 4 is contained in the cutter guard plate 11. When it is necessary to cut paper, pressing the pressing housing 1 can make the circular cutter 4 extend downward to below the cutter guard plate 11, thereby achieving the cutting effect.

[0031] The pressing or rebounding reset of the pressing shell 1 is controlled by two springs 7. Even if the two springs 7 are compressed asynchronously, the circular cutter 4 can be used normally when it is tilted downward. The contact between the circular cutter 4 and the paper is also a straight line contact. Compared with the tilting downward movement of other cutter heads, the paper will not be wrinkled. Therefore, even if it is tilted downward, the normal cutting of the paper can be guaranteed.

[0032] In this embodiment, a circular slot is integrally formed on the inner side wall of the pressing housing 1, and an insert block 10 for inserting into the circular slot is fixedly provided on the circular cutter 4, and the circular cutter 4 is fixedly connected to the buckle seat 3 through the insert block 10. The insert block 10 is interference-fitted with the circular slot, so that the circular cutter 4 and the pressing housing 1 are fixedly connected together, and the circular cutter 4 and the pressing housing 1 can move up and down together.

[0033] In this embodiment, the soft PVC pad is in contact with the bottom surface of the sliding plate 2. The use of the soft PVC pad can increase the cutting stress of the cutter, increase the thickness of the paper to be cut, and protect the desktop from being scratched.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered as within the scope of this specification. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
