[0025] Force the shift lever 306 to move to one side, and then through the cooperation of the inclined surface on one side of the bottom end of the clamping plate 304 and the inclined surface on one side of the helical teeth 303, the force spring 305 can move upward and the force spring 305 is compressed. Therefore, force is required to move the clamping plate 304 to prevent the clamping plate 304 from moving randomly during the pencil sharpening work. The movement of the adjusting slider 307 can drive one end of the blade body 4 to move, so as to achieve the effect of adjusting the use angle of the blade body 4, and then different types of pen cores can be sharpened for use, making the pencil sharpener more practical.

[0026] It should be noted that by lifting the shift lever 306, the force - giving spring 305 is separated from the helical tooth 303. The force - giving spring 305 will be compressed, and then the shift lever 306 is moved to one side, so that the adjusting slider 307 drives one end of the blade body 4 to retract, enabling the blade body 4 to return to the horizontal state.

[0027] Refer to Figure 1 and Figure 2 A chip - collecting box 101 is slidably arranged at the bottom end of the pencil sharpener housing 1. An opening - closing door 102 is rotatably arranged on one side of the pencil sharpener housing 1. A pen - clamping assembly 103 is embedded on one side of the opening - closing door 102. A pen - inserting port 104 is arranged on one side of the pen - clamping assembly 103. The opening - closing door 102 is fixed to one side of the pencil sharpener housing 1 by a magnet. A handle 201 is fixedly arranged on one side of the tool rest 2. A short - circuit post is arranged between the tool rest 2 and the handle 201, and the short - circuit post penetrates and is rotatably arranged on the other side of the pencil sharpener housing 1.

[0028] Insert the pen into the interior of the pencil sharpener housing 1 through the pen - inserting port 104, and the pen - clamping assembly 103 fixes the pen. The pen - clamping assembly 103 is a prior art and will not be elaborated here. Subsequently, rotate the handle 201, and the handle 201 drives the tool rest 2, the angle - adjusting structure 3, the blade body 4, and the cleaning brush 5 to rotate around the circumference together through the short - circuit post, thereby performing the pencil - sharpening work.

[0029] Refer to Figure 2 and Figure 3 At the other end of the blade body 4, a connecting rod 401 is fixedly arranged. The two ends of the connecting rod 401 are rotatably arranged with a transfer bracket 402. On the other side of the transfer bracket 402, a rotating cutter gear 403 is fixedly arranged. A first tooth ring 6 is meshed on the outside of the rotating cutter gear 403. On the outside of the first tooth ring 6, clamping blocks 601 are symmetrically fixedly arranged. A connecting frame 602 is detachably arranged on the outside of the clamping blocks 601, and the connecting frame 602 is detachably arranged on both sides inside the pencil sharpener housing 1. It also includes a cleaning brush 5. The cleaning brush 5 is arranged outside the blade body 4. The cleaning brush 5 is rotatably arranged on one side of the transfer bracket 402. On the outside of the other end of the cleaning brush 5, a fixed brush holder 502 is rotatably arranged. At the other end of the cleaning brush 5, a rotating brush gear 501 is fixedly arranged. The fixed brush holder 502 is detachably arranged at the tops of the upper cover frame 301 and the transfer bracket 402. At one end of the cleaning brush 5, a rotating brush gear 501 is fixedly arranged. A second tooth ring 7 is meshed on the outside of the rotating brush gear 501. The outer diameter of the second tooth ring 7 is the same as that of the first tooth ring 6. On the outside of the second tooth ring 7, clamping blocks 601 are symmetrically fixedly arranged.

[0030] Among them, when the blade body 4 makes a circumferential movement, it will drive the rotating cutter gear 403 to move together. Through the cooperation of the rotating cutter gear 403 and the first tooth ring 6, the rotating cutter gear 403 will rotate during the circumferential movement, thereby driving the transfer bracket 402 and the blade body 4 to rotate together, thus performing the pencil - sharpening work on the pen.

[0031] When the upper cover frame 301 rotates circumferentially, the rotary brush gear 501 will cooperate with the second toothed ring 7, so that the rotary brush gear 501 can rotate and drive the cleaning rotary brush 5 to rotate. The rotation of the cleaning rotary brush 5 can clean the pen shavings outside the blade body 4, prevent the pen shavings from affecting the pencil sharpening work of the blade body 4, and thus improve the pencil sharpening quality.

[0032] The working principle of the present utility model is as follows: Insert the pen into the interior of the pencil sharpener housing 1 from the pen inlet 104, and the pen clamping assembly 103 fixes the pen. The pen clamping assembly 103 is a prior art and will not be elaborated here. Subsequently, rotate the handle 201, and the handle 201 drives the tool holder 2, the angle adjustment structure 3, the blade body 4 and the cleaning rotary brush 5 to rotate circumferentially together through the short connection column. Among them, when the blade body 4 performs circumferential movement, it will drive the rotary cutter gear 403 to move together. Under the cooperation of the rotary cutter gear 403 and the first toothed ring 6, the rotary cutter gear 403 will rotate during circumferential movement, thereby driving the adapter frame 402 and the blade body 4 to rotate together, so as to perform the pencil sharpening work on the pen;

[0033] When performing pencil sharpening work on the pen according to different writing requirements, forcefully open the opening and closing door 102 and rotate it to one side. The opening and closing door 102 is fixed by a magnet, so it is convenient to open and close. Then, forcefully move the shift lever 306 to one side. Further, through the cooperation of the inclined surface on one side of the bottom end of the clamping plate 304 and the inclined surface on one side of the helical tooth 303, the biasing spring 305 can move upward and the biasing spring 305 is compressed. Therefore, force is required to move the clamping plate 304 to prevent the clamping plate 304 from moving randomly during the pencil sharpening work. The movement of the adjusting block 307 can drive one end of the blade body 4 to move, so as to achieve the effect of adjusting the use angle of the blade body 4, and then different types of pen cores can be sharpened for use, making the pencil sharpener more practical. By lifting the shift lever 306, the biasing spring 305 is separated from the helical tooth 303, and the biasing spring 305 will be compressed. Then, move the shift lever 306 to one side, so that the adjusting block 307 drives one end of the blade body 4 to retract, so that the blade body 4 can return to the horizontal state;

[0034] When the upper cover frame 301 rotates circumferentially, the rotary brush gear 501 will cooperate with the second toothed ring 7, so that the rotary brush gear 501 can rotate and drive the cleaning rotary brush 5 to rotate. The rotation of the cleaning rotary brush 5 can clean the pen shavings outside the blade body 4, prevent the pen shavings from affecting the pencil sharpening work of the blade body4, and thus improve the pencil sharpening quality.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
