[0021] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an office paper cutter, including a paper cutting board 1, two fixing blocks 2 are fixedly installed on one side of the outer wall of the paper cutting board 1, a limiting rod 3 is fixedly installed between the opposite sides of the outer walls of the two fixing blocks 2, the outer wall of the limiting rod 3 is movably sleeved with a fixing bracket 4, the top of the fixing bracket 4 is threadedly connected with a screw rod 5, the top of the screw rod 5 is fixedly installed with a handle 6, the bottom of the screw 5 is rotatably connected with a pressing plate 7, the top of the fixing bracket 4 is provided with two through holes 8, the inner walls of the two through holes 8 are movably inserted with connecting rods 9, and the bottoms of the two connecting rods 9 are fixedly connected to the top of the pressing plate 7.
[0024] The effect achieved by the entire embodiment 1 is that the office paper to be cut to a size is placed on the cutting paper board 1, and then the handle 6 installed on the top of the screw rod 5 is rotated to make it rotate downward on the top of the fixed bracket 4. Since a pressing plate 7 is rotatably connected to the bottom of the screw rod 5, two through holes 8 are opened on the top of the fixed bracket 4, and two connecting rods 9 are installed on the top of the pressing plate 7 and are movably inserted in the two through holes 8, so that the pressing plate 7 can be driven to move downward stably and limit the office paper on the cutting paper board 1, and then the two connecting rods 9 are fixedly sleeved with a limiting ring 10, so that the two connecting rods 9 will not be separated from the fixed bracket 4, and then when the user needs to cut the office paper, there is no need to hold down the office paper with hands, which reduces the user's fatigue intensity and improves the qualified rate of office paper cutting. It also reduces the problem of user operation safety, thereby improving the use effect of the office paper cutter.
[0025] Embodiment 2, as Figure 2-Figure 4As shown, the outer walls of the two connecting rods 9 are movably sleeved with limit rings 10, a forward and reverse motor 11 is fixedly installed on the other side of the outer wall of the cutting board 1, a threaded rod 12 is fixedly installed on one side of the outer wall of the forward and reverse motor 11, and the inner wall of the fixed bracket 4 is threadedly connected to the outer wall of the threaded rod 12, a limit column 13 is fixedly installed on the other side of the outer wall of the cutting board 1, and the outer wall of the threaded rod 12 is movably inserted into the inner wall of the limit column 13, two electric push rods 14 are fixedly installed on the inner wall of the fixed bracket 4, and the output ends of the two electric push rods 14 are fixedly installed with alignment plates 15, a paper cutting tool 16 is fixedly installed on the other side of the outer wall of the cutting board 1, and a plurality of scale marks 17 are provided on the top of the cutting board 1.
[0026] The effect achieved by the entire embodiment 2 is that when the office paper to be cut is placed on the cutting board 1, the forward and reverse motor 11 installed on the other side of the outer wall of the cutting board 1 is started according to the size of the office paper, so that it drives the threaded rod 12 to rotate inside the limiting column 13. Since the fixed bracket 4 is not only threadedly connected to the threaded rod 12, but also movably sleeved on the limiting rod 3, the fixed bracket 4 can move stably on the limiting rod 3 and the threaded rod 12 at the same time, and move it to a suitable position as needed, and then start the two electric push rods 14 installed on both sides of the inner surface of the fixed bracket 4, so that it drives the two alignment plates 15 to move relative to each other, and tidy up the office paper, and then limit it, which can adapt to limited cutting of office paper of different sizes, has high practicality, and further improves the use effect of the office paper cutter.
[0027] Working principle: First, place the office paper to be cut on the cutting board 1, and according to the multiple scale marks 17 on the cutting board 1, it can be placed in a suitable position, and then start the forward and reverse motors 11 to drive the fixed bracket 4 to move on the limit rod 3 and the threaded rod 12 at the same time until it is moved to a suitable position above the office paper, and then start the two electric push rods 14 to drive the two alignment plates 15 to move relative to each other and align the office paper, and then use the handle 6 to rotate the screw 5 threadedly connected to the fixed bracket 4. Since the bottom of the screw 5 is rotatably connected with a pressure plate 7 and is movably inserted in the two through holes 8, The connecting rods 9 are all installed on the top of the pressing plate 7, so that the pressing plate 7 can move downward stably and limit the office paper on the cutting board 1. Through the action of the two limiting rings 10, the two connecting rods 9 will not be separated from the fixed bracket 4. Finally, the user uses the paper cutting tool 16 to cut the limited office paper. The user does not need to press the office paper with his hands, which reduces the user's fatigue intensity. When the paper cutting tool 16 is used to cut it, the user's operating safety problem is also reduced, and the qualified rate of cutting office paper is improved, thereby improving the use effect of the office paper cutting tool.
[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
