The adjusting mechanism 4 includes a push block 43 slidably disposed in the slide hole 16, and a dial 42 slidably disposed in the limit hole 14 and driving the limit rod 41 to move. The limiting rod 41 is detachably connected with the pushing block 43. By rotating the dial 42, the limiting rod 41 and the pushing block 43 move towards the pencil sharpening hole 12, so that the length of the pencil extending into the mounting groove 11 is shortened, and the pencil sharpener can machine a thick pencil head.

As shown in fig. 2 and 4, an end of the dial 42 facing the pencil sharpening hole 12 is a slope, and the stopper rod 41 abuts against the slope of the dial 42. Five arc-shaped grooves 421 are formed on the inclined surface of the dial 42, so that the limiting rod 41 can be embedded into the arc-shaped grooves 421, and the effect that the dial 42 is not easy to move in the machining process of the pencil sharpener is achieved. When the limiting rod 41 is inserted into the different arc-shaped grooves 421, the distance between one end of the limiting rod 41 close to the pencil sharpening hole 12 and the pencil sharpening hole 12 is different, so that the thicknesses of the pencils processed by the pencil sharpener are different.

As shown in fig. 2 and 4, a circular shaft 31 is fixedly connected to one end of the handle 3 away from the pencil sharpening hole 12, the dial 42 is sleeved on the circular shaft 31, and a rocker 422 is fixedly connected to one end of the dial 42 away from the axis of the circular shaft 31, so that a user can conveniently drive the dial 42 to rotate by hand through the rocker 422. The handle 3 is provided with an adjusting groove 32, and the rocker 422 can move in the adjusting groove 32, so that the maximum distance of rotation of the rocker 422 along the axis of the circular shaft 31, namely the maximum distance of rotation of the dial 42 along the axis of the circular shaft 31, is limited.

As shown in fig. 2 and 4, three clamping holes 34 are formed in the handle, a protection plate 33 for covering the dial plate 42 is arranged at one end, away from the fixing ring 2 of the pencil sharpening hole 12, of the handle 3, three clamping blocks 35 embedded into the three clamping holes 34 are fixedly connected to the protection plate 33 respectively, five scale grooves 36 are formed in one end, away from the handle 3, of the protection plate 33, and a user can know which thickness of pencil can be machined by the pencil sharpener at present. Further, the scale slots 36 may be of different sizes to facilitate viewing and judgment by the user.

As shown in fig. 1, 2 and 5, the limiting rod 41 is provided with a guide slot 411, and the lower end of the pushing block 43 is fixedly connected with a guide block 435 embedded in the guide slot 411. So that the limiting rod 41 drives the pushing block 43 to move together when moving. The tool rest 1 is provided with two positioning holes 19, and the two positioning holes 19 are respectively located at two ends of the sliding hole 16. The tool rest 1 is provided with a pressing block 432 covering the sliding hole 16, two ends of the pressing block 432 are respectively and fixedly connected with an inserting block 433, and the two inserting blocks 433 are respectively arranged through the two positioning holes 19. A triangular block 434 is fixedly connected to one end of the side edge of the insert 433, which is far away from the pressing block 432. The insert 433 is inserted into the positioning hole 19 so that the pressing piece 432 is connected to the tool holder 1. The corner block 434 has a guiding function when the insert 433 is inserted into the positioning hole 19, and the triangular block 434 abuts against the tool holder 1 after the triangular block 434 passes through the positioning hole 19, thereby preventing the press block 432 from being separated from the tool holder 1.

As shown in fig. 2 and 5, a placement groove 15 is formed at one end of the tool holder 1 away from the pencil sharpening hole 12, a disc 412 is fixedly connected to the limiting rod 41, and the disc 412 slides in the placement groove 15. The limiting rod 41 is sleeved with a spring 17, and two ends of the spring 17 are respectively abutted with one end of the tool holder 1 far away from the pencil sharpening hole 12 and the disc 412, so that the limiting rod 41 is abutted with the dial 42 more tightly. The dial 42 is driven to rotate, the spring 17 is compressed when the dial 42 pushes the limiting rod 41 to move towards the pencil sharpening hole 12, and when the dial 42 rotates reversely, the spring 17 is reset to push the limiting rod 41 to move away from the pencil sharpening hole 12. The spring 17 and the disc 412 are provided so that the stopper lever 41 is always abutted against the dial 42 during rotation of the dial 42.

As shown in fig. 2 and 3, the positioning disc 18 is fixedly connected to the tool holder 1, and the positioning groove 23 for embedding the limiting disc is formed in the fixing ring 2, so that the pencil is prevented from being chipped during processing from entering between the handle 3 and the fixing ring 2, and the adjusting mechanism 4 is prevented from being affected.

The working principle is as follows: the thick pencil needs to be machined, the rocker 422 is driven to rotate the dial 42, the dial 42 is rotated to push the limiting rod 41 and the push block 43 to move towards the pencil sharpening hole 12, and meanwhile, the disc 412 pushes the spring 17 to compress. Then the pencil is inserted into the pencil sharpening hole 12, the handle 3 is driven to drive the hob 13 to rotate so as to machine the pencil, and therefore a thick pencil is obtained.

The thinner pencil needs to be processed, the rocker 422 is driven to rotate the dial 42, the dial 42 rotates, the spring 17 resets, the limiting rod 41 is pushed to move away from the pencil sharpening hole 12, and therefore the pushing block 43 moves away from the pencil sharpening hole 12. And then the pencil is inserted into the pencil sharpening hole 12, and the handle 3 is driven to drive the hob 13 to rotate so as to machine the pencil, so that a thinner pencil is obtained.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
