Description

12211H V. Description of the invention (1) The technical field to which the invention belongs Device This case is a cutting device, especially for cutting paper. Prior art

Please refer to the first figure, which is a schematic diagram of the appearance and structure of a commonly used paper cutting device 'where the paper cutting device i 〇 has a sliding groove 丨 i, a sliding object 1 2' wherein the sliding object 12 has The cutting element (such as a blade, not shown in the figure) at the bottom can slide along the slide handle. When using the paper cutting device 10, 'the user only needs to place the paper in the space 111 below the sliding object 12' and then press the sliding object 丨 2 to make the cutting element contact the paper 'and press the sliding object and It can slide back and forth on the slide rail 丨 丨 to drive the cutting element to cut the paper to achieve the purpose of cutting paper. However, due to the structural design of the conventional paper cutting device, the user must press down the sliding object 12 to make the cutting element contact the paper downward, but increasing the downward pressure will cause an increase in friction force, and then the sliding object 12 ^ slip The difficulty of sliding back and forth is increased, which makes the operation difficult for the user. And how to improve the lack of conventional methods is to develop the invention content of this case.

1221111 device, which is used to place a piece of the sheet; a slide; a sliding element is arranged on the square turner 'carrying the moving element on the slide rail' against the starting position of the cut and converted to a V. Description of the invention (2) The case includes: a slide back and forth on a placement platform; a component that drives the user to connect the cutting body to a rotator and switch back to the starting point. There is an elastic piece on the rotator, and the rotator moves upwards according to the upper and lower angles. The starting position of the cutter is downward and the torsional force according to the upper system. The rotator is regarded as a cutting and placing platform for a cutter and moves; When a force rotates, the device pushes down against the rotator and the position where the external force disappears. The above-mentioned conception of the slide is designed. The present structure resists the return force of the external force. The above-mentioned concept, this slope structure, when the transition to the roof abuts to contact the above-mentioned concept, this spring, connects the user outside to contact the sliding element, the elastic force. The ruling described in the case can be followed by the ruling described in the case when the sliding element is lost. When the rotator in the bomb case is accepted as the position, the ruling described in the sheet case is applied to the rotator. The force rotates from the sheet; in between, when the system cuts the extract, its rail is fixed on it, and it can be along the slide rail, and it is subject to the sliding cutter, which is subject to the working position, and An elastic user is provided with the rotary cutting device, wherein the sliding element slides back and forth. The cutting device, wherein the cutting device is provided on the cutting device, when the user provides the cutting device for the sheet structure, wherein the user of the rotator rotates by external force and the slope structure gradually changes the cutting device, wherein the elastic body And the sliding element, when the starting position is switched to the working position

I2211H V. Description of the invention (3) A twist occurs at the $ position, and when the user loses the external force of the rotator, the restoring force of the torsion spring will cause the rotator to rotate back to the starting position. According to the above concept, this case In the cutting device, the sheet 1 is paper. : According to the above-mentioned concept, the cutting device described in this case, wherein the cutting includes a cutter. To explain this case with a simple diagram, the following diagrams and detailed explanations can be used to get a deeper understanding of the first picture: it is a commonly used paper-cut package.
