[0022] Please see Figures 1-4 An electric paper cutter includes an electric scissor body 1, a cutting auxiliary mechanism 2 on the outside of the electric scissor body 1, a fixed frame 201, a movable frame 203 above the fixed frame 201, the inner wall of the fixed frame 201 being fixedly connected to the outer surface of the electric scissor body 1, anti-slip pads 4 being fixedly connected to both sides of the electric scissor body 1, and several identical anti-slip protrusions 5 being fixedly connected to the side of the two anti-slip pads 4 that are far apart from each other. By setting the anti-slip protrusions 5, the anti-slip properties of the outer surface of the anti-slip pads 4 can be increased. By setting the anti-slip pads 4 and the anti-slip protrusions 5, the anti-slip properties of both sides of the electric scissor body 1 can be increased, thereby increasing the stability when holding the electric scissor body 1.

[0023] Two electric telescopic rods 202 are fixedly connected to the inner wall of the fixed frame 201. The telescopic end of each electric telescopic rod 202 is fixedly connected to the bottom surface of the movable frame 203. A movable clamp 204 is provided below the movable frame 203. Two limiting slide rods 3 are fixedly connected to the upper surface of the fixed frame 201. The outer surface of each limiting slide rod 3 is slidably connected to the inside of the movable frame 203. By setting the limiting slide rods 3, the movable frame 203 can slide up and down inside the movable frame 203, thereby increasing the stability of the movable frame 203 relative to the fixed frame 201.

[0024] Three guide rods 205 are fixedly connected to the upper surface of the movable clamp 204. The outer surface of each guide rod 205 is slidably connected to the interior of the movable frame 203. A return spring 206 is sleeved on the outer surface of each guide rod 205. The two ends of each return spring 206 are in contact with the bottom surface of the movable frame 203 and the upper surface of the movable clamp 204, respectively. A support 6 is fixedly connected to the front of the electric scissors body 1. A pull rod 7 is fixedly connected to the inner wall of each support 6. By setting the pull rod 7, a rotation base surface can be provided for the hanging structure inside the support 6. By setting the support 6 and the pull rod 7, the entire electric scissors can be suspended and placed together with the above-mentioned hanging structure.

[0025] A controller 207 and a self-reset switch 208 are fixedly connected to the upper surface of the electric scissors body 1. The controller 207 can be an MCU or an Arduino series, which is small in size, low in cost, and low in power consumption, making it suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminals of various electrical components through digital output pins and control the power of various components through analog output pins. Specific control logic and timing can be implemented by writing code. The self-reset switch 208 adopts existing mature technology. When an external force is applied to it, the switch contacts close, and the circuit is connected. After the external force disappears, the elastic element will cause the contacts to quickly return to the open state, realizing the automatic reset function. Then, with the cooperation of the controller 207, pressing the self-reset switch 208 can control the blades of the electric scissors body 1 to move closer to each other for cutting, and releasing the self-reset switch 208 can move the blades of the electric scissors body 1 away from each other to prevent accidental cutting. The support 6 is provided with a lifting ring 8 inside. The inner wall of the lifting ring 8 is rotatably connected to the outer surface of the pull rod 7. By setting the lifting ring 8, it can rotate around the outer surface of the pull rod 7 inside the support 6, thus facilitating the hanging of the entire electric scissors.

[0026] An elongated button 209 is fixedly connected to the bottom surface of the electric scissors body 1. The elongated button 209 also adopts the same mature technology as the self-resetting switch 208. When an external force is applied to it, the switch contacts close, the circuit is connected, and after the external force is removed, the elastic element will cause the contacts to quickly return to the open state, realizing the automatic reset function. Thus, when the electric scissors body 1 is held, the elongated button 209 will be pressed. At the same time, with the cooperation of the controller 207, the two electric telescopic rods 202 will return to their original extended state. The state gradually contracts, causing the fixed frame 201 and the movable clamp 204, which are separated from each other, to move closer to each other. Only when the elongated button 209 is released will the controller 207 control the two electric telescopic rods 202 to extend again. The electric scissor body 1, the two electric telescopic rods 202, the self-reset switch 208 and the elongated button 209 are all electrically connected to the controller 207 through wires. The upper surface of the fixed frame 201 is fixedly connected to the first silicone pad 9, and the bottom surface of the movable clamp 204 is fixedly connected to the second silicone pad 10.

[0027] The working principle of this utility model is as follows: When in use, hold the electric scissors body 1 so that the fixed frame 201 is positioned below the paper to be cut, ensuring the paper is flat. Then, press the elongated button 209, causing the controller 207 to control the two electric telescopic rods 202 to shorten simultaneously. This causes the movable frame 203 and the movable clamp 204 to gradually approach the fixed frame 201. The fixed frame 201 and the movable clamp 204 then clamp the paper to be cut. The guide rod 205 sliding up and down inside the movable frame 203, and the return spring 206 being compressed by the movable clamp 204 and the movable frame 203, allow the fixed frame 201 and the movable clamp 204 to clamp papers of different thicknesses. Thus, at this point... Pressing the self-reset switch 208 causes the controller 207 to control the scissor head of the electric scissors body 1 to precisely and perfectly cut the paper held by the fixed frame 201 and the movable clamp 204, which greatly improves the cutting effect and expands its cutting application scenarios. When the scissor head of the electric scissors body 1 needs to open again, simply release the press of the self-reset switch 208. When the entire scissors needs to be removed from the paper, simply release the press of the long button 209. The design of the entire electric paper cutting scissors effectively solves the problem that the lack of a clamping auxiliary structure to improve cutting accuracy makes it difficult to guarantee the cutting precision of the scissors, thus affecting the cutting effect and limiting its cutting application scenarios.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
