[0024] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1-6 As shown, a paper cutter includes a housing 1 and at least two sets of wheels 2 provided at the bottom of the housing 1. A cutter assembly 3 for cutting paper is provided at the bottom of the housing 1. The cutter assembly 3 is provided between each set of wheels 2. The cutter assembly 3 includes a blade clamp 31 provided at the lower end of the housing 1. A blade 32 is assembled in the blade clamp 31. The blade 32 is vertically arranged along the cutting direction, and the blade head of the blade 32 is tilted forward. The cutting edge of the blade 32 is arranged toward the bottom of the housing to achieve cutting of paper.

[0027] This solution provides a housing 1 and a wheel 2. During the paper cutting process, the rolling wheel 2 is used as a guide structure to improve the smoothness of the cutting. In addition, when the wheel 2 rolls on the paper surface, it can also flatten the surrounding area of ​​the paper, further improving the paper cutting effect. The blade 32 is hidden between the wheel 2 under the housing 1 and is protected by a blade clamp 31. The housing 1 and the wheel 2 themselves have a certain protective effect to prevent the blade 32 from cutting the user.

[0028] The blade clamp 31 extends forward along the front end of the cutting direction to form a paper scraping end 33. In this solution, the blade edge of the blade 32 is set to be inclined upward, so the blade edge is hidden between the blade clamp 31 and the shell 1 and will not be exposed to the outside to cause danger. Therefore, there is no need for storage protection, and the paper scraping end 33 is set to scoop up and support the paper, and the blade 32 cuts the paper from bottom to top. Compared with the top-down cutting method of the traditional paper cutter, this bottom-up cutting method will not cut the supporting platform under the paper.

[0029] The housing 1 comprises an upper housing 11 and a lower housing 12, which are connected to each other, and a chassis 13 disposed at the bottom of the lower housing for mounting the wheels 2 and the blade holder 31. A snap ring is provided on the lower housing 12, and the bottom of the upper housing 11 is connected to the lower housing 12 by fitting over the snap ring. This method can be achieved by a snap connection or other fixing components.

[0030] A flat handle is provided on the upper shell 11 , and the flat surface of the handle coincides with the vertical plane where the blade is located, making it convenient to hold the blade for cutting operations.

[0031] The bottom of the chassis 13 is recessed upward to form a bottom groove 131 for accommodating the cutter assembly 3, and the bottom groove 131 is further recessed upward to form a fixing groove 132 and a mounting seat 133, wherein clamping parts are provided on both sides of the blade clamp 31, and the clamping parts are inserted into the fixing groove 132 to clamp the blade 32. In order to simplify the disassembly and assembly steps of the blade 32, the disassembly and assembly of the blade 32 are integrated with the disassembly and assembly of the blade clamp 31. When installing the blade clamp 31, the clamping part of the blade clamp 31 is inserted into the fixing groove 132 to clamp the blade 32, and then the blade clamp 31 can be fixed.

[0032] A docking seat 34 is provided at the rear end of the blade clamp 31 along the cutting direction. The docking seat 34 is inserted into the mounting seat 133 and fixedly connected by a self-tapping screw 4 .

[0033] The wheels 2 have two groups, front and back, and the blades 32 are located on the central axis between each group of wheels 2. They are guided by the wheels 2 and press down the paper during the guiding process to make the surrounding paper flatter. Setting the blades 32 on the central axis of the wheels 2 can make the force on the paper more balanced.

[0034] The specific implementation method is as follows: when cutting paper, the paper is flattened, the upper shell 11 is held and the paper cutter is moved along the preset cutting path. First, the paper scraping end 33 scoops up the edge of the paper, and then the wheel 2 is pressed on the paper. When the wheel 2 rolls, the paper scraping end 33 slightly lifts the paper, and the blade 32 cuts the paper from bottom to top.

[0035] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
