[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] Please see Figure 1-5 A pencil sharpener tip adjustment mechanism includes a base 1, a slot 2 at the bottom of the base 1, a rotating rod 3 movably connected inside the base 1, a knob 4 fixedly connected to the bottom end of the rotating rod 3, a sliding groove 5 inside the knob 4, a spring block 6 installed inside the knob 4, a receiving frame 7 fixedly connected to the top of the rotating rod 3, and pencil sharpening boxes 8 fixedly connected to the outer wall of the receiving frame 7. The base 1 and the receiving frame 7 form a rotating structure through the rotating rod 3 and the receiving frame 7, and the base 1 and the knob 4 form a rotating structure through the rotating rod 3 and the knob 4 form a sliding structure through the sliding groove 5 and the spring block 6, and the spring block 6 is engaged with the base 1 through the slot 2. The receiving frame 7 is cross-shaped. The four pencil sharpening boxes 8 have pencil tip receiving slots of different diameters inside, which can facilitate the adjustment of the pencil tip tip thickness according to the actual pencil sharpening needs.

[0027] Please see Figure 1-5 A pencil sharpener tip adjustment mechanism is provided. The pencil sharpener box 8 has a mating groove 9 and a threaded hole 10 inside. A blade 11 is installed on the outer wall of the pencil sharpener box 8. A bolt 12 is movably connected inside the pencil sharpener box 8. The pencil sharpener box 8 is engaged with the blade 11 through the mating groove 9, and the pencil sharpener box 8 is threadedly connected to the bolt 12 through the threaded hole 10, which facilitates the disassembly and replacement of the blade 11.

[0028] Please see Figure 1-5A pencil sharpener tip adjustment mechanism is disclosed. The base 1 has a slot 13 inside, and a groove 14 is formed on the inner side wall of the slot 13. A chip collection cover 15 is installed on the outer wall of the base 1, and a protrusion 16 is fixedly connected to the outer wall of the chip collection cover 15. A pencil insertion hole 17 is formed inside the chip collection cover 15. The base 1 is engaged with the chip collection cover 15 through the slot 13, and the groove 14 is symmetrically arranged with the central axis of the slot 13. The protrusion 16 is engaged with the base 1 through the groove 14, and the protrusion 16 is elastically set to facilitate the collection and cleaning of waste chips generated during pencil sharpening.

[0029] Working principle: During use, rotating the knob 4 causes the slot 2 to press against the spring block 6, causing the spring block 6 to retract into the slide groove 5 and release the limit on the knob 4. This drives the rotating rod 3 to rotate, causing the pencil sharpener 8, which is fixedly connected to the outer wall of the receiving frame 7, to rotate. When the pencil sharpener 8 of the desired tip thickness aligns with the pencil insertion hole 17, the spring block 6, under the action of the spring, can be locked into the corresponding slot 2 for a limiting action. The pencil is then passed through the pencil insertion hole 17 and inserted into the pencil sharpener 8. Rotating the pencil sharpens it, causing the shavings to fall into the shavings collection hood 15. Collect the chips and pull the chip collection cover 15 upwards.
