Description

Technical Field

[0001] This utility model belongs to the field of pencil sharpener technology, and in particular relates to a pencil sharpener with a pen grip height guide. Background Technology

[0002] Pencil sharpeners, also known as pencil shavings, are essential stationery for students. They come in simple single-hole and double-hole designs, as well as a locomotive-style design. The locomotive style offers advantages such as automatic feeding, automatic shavings collection, and effortless use.

[0003] To improve students' pen grip standards, it is necessary to mark the pen grip position to constrain the grip position. However, existing pencil sharpeners can only sharpen the pencil. Since the overall length of the pencil will shorten after each sharpening, the pen grip position will also change with the change in length. Obviously, a fixed pen grip height guide structure cannot meet the needs.

[0004] To address the aforementioned issues, this application proposes a pencil sharpener with a pen grip height indicator. Utility Model Content

[0005] The purpose of this invention is to provide a pencil sharpener with a pen grip height guide, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pencil sharpener with a pen grip height guide, comprising a pencil sharpener body, a clamping component at the front end of the pencil sharpener body, a mounting box at the front end of the clamping component, a partition on the side of the mounting box near the clamping component, two sets of circumferentially distributed slotting components inside the mounting box, each slotting component creating an annular groove on the outside of the pencil, and pressing components symmetrically arranged on the side of the mounting box to cooperate with the two sets of slotting components, the slotting components contacting the pencil through the pressing of the pressing components, and an adjusting component for adjusting the slot height between the mounting box and the two sets of slotting components; each slotting component contains a V-shaped blade, the V-shaped blade having a blade edge at the front end and rounded corners on both sides to chamfer the ends of the annular groove, and a chip removal groove on the inner side of the V-shaped blade for easy chip removal.

[0008] Furthermore, the adjusting component includes an adjusting wheel rotatably disposed at the front end of the mounting box and a lead screw rotatably disposed between the mounting box and the partition, as well as an adjusting seat threaded onto the outside of the lead screw, with the two sets of slotted components circumferentially distributed and installed on the adjusting seat.

[0009] Furthermore, both the adjusting wheel and the mounting box have through holes for inserting a pencil. The adjusting wheel is located inside and at the front end of the mounting box. Multiple lead screws are distributed circumferentially along the adjusting wheel, and all of the lead screws simultaneously engage with the adjusting seat threadedly.

[0010] Furthermore, a gear ring is provided on the outer side of the inner side of the adjusting wheel, and a gear that meshes with the gear ring is provided at one end of the lead screw.

[0011] Furthermore, the grooving component also includes a connecting plate fixed to the V-shaped blade and sliding through the adjusting seat, a pressure plate fixed to the other end of the connecting plate, and a first spring disposed between the pressure plate and the adjusting seat.

[0012] Furthermore, the pressing component includes a slide fixed to the inside of the mounting box and the partition, a pressure seat sliding in the slide, a second spring fixed to one end of the pressure seat and passing through the side of the mounting box, and a second spring supported between the inside of the mounting box and the pressure seat and sleeved on the outside of the guide rod.

[0013] Furthermore, a push block is fixed to the end of the guide rod away from the pressure seat. The push block is located on the side of the mounting box, and the pressure seat covers the adjustment range of the adjustment component and the slotted component.

[0014] This utility model has the following beneficial effects:

[0015] This utility model provides an installation box at the front end of the clamping component, and then sets a slotted component and a pressing component inside the installation box. When the pencil is sharpened, it is not pulled out and rotated in the opposite direction. At the same time, the pressing component is pressed and the slotted component is driven to form an annular groove on the pencil. The annular groove guides and constrains the grip position, thereby achieving the purpose of correcting the grip height.

[0016] This invention provides an adjustment component between the mounting box and the slotted component. The adjustment component can adjust the position of the slotted component without affecting the cooperation between the slotted component and the pressing component. This allows it to adapt to different hand sizes during the growth stage of students and to a wider range of age groups, thus improving both adaptability and practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-9 As shown, this utility model is a pencil sharpener with a pen grip height guide, including a pencil sharpener body 1, a clamping component 2 at the front end of the pencil sharpener body 1, a mounting box 3 at the front end of the clamping component 2, a partition 31 on the side of the mounting box 3 near the clamping component 2, two sets of circumferentially distributed slotted components 5 inside the mounting box 3, the slotted components 5 opening annular grooves on the outside of the pencil, and pressing components 6 symmetrically arranged on the side of the mounting box 3 to cooperate with the two sets of slotted components 5, the slotted components 5 contacting the pencil through the pressing of the pressing components 6, and an adjusting component 4 for adjusting the slot height is also provided between the mounting box 3 and the two sets of slotted components 5; a V-shaped blade 51 is provided in the slotted component 5, the V-shaped blade 51 has a blade edge 511 formed at the front end, and rounded corners 512 formed on both sides to chamfer the two ends of the annular groove, and a chip removal groove 513 is provided on the inner side of the V-shaped blade 51 to facilitate chip removal.

[0033] The adjusting component 4 includes an adjusting wheel 41 rotatably disposed at the front end of the mounting box 3, a lead screw 42 rotatably disposed between the mounting box 3 and the partition 31, and an adjusting seat 43 threaded onto the outside of the lead screw 42. Two sets of slotted components 5 are circumferentially distributed and installed on the adjusting seat 43. In this embodiment, the front end of the adjusting wheel 41 is placed outside the mounting box 3 to facilitate the adjustment of the slotted components 5. The adjusting wheel 41 and the mounting box 3 can be connected by a damped rotation to better ensure the stability after adjustment.

[0034] Both the adjusting wheel 41 and the mounting box 3 have through holes for inserting pencils. The adjusting wheel 41 is located inside and at the front end of the mounting box 3. Multiple lead screws 42 are distributed circumferentially along the adjusting wheel 41. These multiple lead screws 42 are threadedly engaged with the adjusting seat 43. A gear ring 411 is provided on the inner and outer sides of the adjusting wheel 41. One end of the lead screw 42 is provided with a gear 421 that meshes with the gear ring 411. In this embodiment, one gear ring 411 drives multiple gears 421 and drives multiple lead screws 42 to rotate simultaneously and engage synchronously with the adjusting seat 43. The multiple lead screws 42 are adjustable and also provide support.

[0035] The grooving component 5 also includes a connecting plate 52 fixed on the V-shaped blade 51 and sliding through the adjusting seat 43, a pressure plate 53 fixed at the other end of the connecting plate 52, and a first spring 54 disposed between the pressure plate 53 and the adjusting seat 43. In this embodiment, the V-shaped blade 51 automatically disengages from the pencil under the action of the first spring 54.

[0036] The pressing component 6 includes a slide 61 fixed to the inside of the mounting box 3 and the partition 31, a pressure seat 62 sliding in the slide 61, a second spring 64 fixed to one end of the pressure seat 62 and passing through the side of the mounting box 3, and a second spring 64 supported between the inside of the mounting box 3 and the pressure seat 62 and sleeved on the outside of the guide rod 63. In this embodiment, when the second spring 64 is reset, the pressure seat 62 does not contact the slotted component 5.

[0037] In this embodiment, the guide rod 63 has a push block 65 fixed at the end away from the pressure seat 62. The push block 65 is located on the side of the mounting box 3. The pressure seat 62 covers the adjustment range of the adjustment component 4 and the slotted component 5. In this embodiment, the push blocks 65 are two symmetrically distributed on the side of the mounting box 3. This utility model is adapted to pencil sharpeners with the clamping and pressing blocks of the clamping component 2 located on the side. In actual use, it is necessary to press the push blocks 65 on both sides and the side button on the side of the clamping component 2 at the same time. By covering the adjustment range of the slotted component 5 with the pressure seat 62, no matter where the slotted component 5 is adjusted within this range, pressing the pressing component 6 can push the slotted component 5 to contact the pencil and open the annular groove.

[0038] Understandably, the combination of the slotted and pressing components creates a ring mark on the outside of the pencil after it has been sharpened, which guides and constrains the height of the grip, helping to correct the grip posture. Secondly, the mounting box allows for adjustment of the slotted component without affecting the cooperation between the slotted and pressing components, thus adapting to the use of students at different growth stages and age groups.

[0039] A specific application of this embodiment is as follows: In the reset state, the pressing component 6 does not contact the slotted component 5, and the slotted component 5 does not contact the pencil. When the pencil sharpener body 1 is in use, the clamping component 2 is pulled out from the front end of the pencil sharpener body 1 and clamps the pencil. The pencil is sharpened by the pencil sharpener body 1. At this time, the pencil is not removed. The pressing component 6 is pressed and the slotted component 5 is pushed to contact the pencil. At this time, the pencil is rotated in the opposite direction, thereby opening an annular groove on the pencil. After releasing the pressing component 6, the slotted component 5 automatically disengages from the pencil, and then the pencil can be removed. To facilitate the reverse rotation of the pencil, as follows: Figure 1 and Figure 3 The button of the clamping component 2 shown is located on the side. When the pressing component 6 is pressed, its button is pressed at the same time, thereby detaching the clamping component 2 from the pencil.

[0040] The grooving component 5 and the pressing component 6 work together: Pressing the pressing blocks 65 on both sides at the same time causes the pressure seat 62 to slide in the slide seat 61 via the guide rod 63. The guide rod 63 is stretched, and the front end of the pressure seat 62 pushes the pressure plate 53. The connecting plate 52 slides in the adjusting seat 43 and pushes the V-shaped blade 51 to contact the pencil. As the pencil rotates, the blade 511 grooves, and the rounded corner 512 rounds the two ends of the groove. The debris after grooving is discharged through the chip discharge groove 513 and falls into the chip groove in the mounting box 3. After a period of use, the chip groove can be removed from the side of the mounting box 3 and emptied.

[0041] The adjustment of the adjusting component 4 is achieved by rotating the adjusting wheel 41 from the front end of the mounting box 3. After the gear ring 411 rotates, it drives the lead screw 42 to rotate in the mounting box 3 through meshing with the gear 421. The moving force generated by the lead screw 42 meshing with the adjusting seat 43 drives the adjusting seat 43 and the slotted component 5 to move and adjust their positions.
