When in use, rotate the gear to lift the top cover, insert the pencil, and then squeeze the pencil sharpener several times to complete the work of sharpening the pencil.

Description

Combination structure of push-type pencil sharpener for one-handed operation

technical field

The utility model relates to a combination structure of a pencil sharpener, more specifically, relates to a combination structure of a single-handed pressing type pencil sharpener.

Background technique

The used pencil sharpener on the existing domestic market mainly contains two kinds: a kind of is the ubiquitous hand-operated pencil sharpener on the market, and another kind is the traditional simple pencil sharpener that only has a blade. These two types of pencil sharpeners require two-handed operation during use, and the disadvantage of this setting is that it does not take into account the crowd who can only operate the pencil sharpener with one hand.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a convenient and humanized single-hand operation push type pencil sharpener combined structure.

The one-handed push-type pencil sharpener combination structure includes: top cover, gear, rack, dust-proof compartment, coiler, central connection gear, plastic shell, extruded parts, torsion spring and dust box; all The above-mentioned ascending gear is placed in the groove of the plastic shell, interlocks with the ascending rack, and the rack is connected with the top cover at the same time. The top of the top cover has a bayonet for putting a pencil; the dust-proof interlayer is a cylindrical hollow structure, which is set on the outside of the coiler; the coiler and the dust-proof interlayer are glued to the central connecting gear; the extruded part and the plastic The casings together form the casing of the pencil sharpener, and a rack is embedded in the middle of the extruded part, and the rack is connected with the intermediate gear.

The beneficial effect of the utility model is: to help the person who can only sharpen the pencil with one hand complete the behavior of sharpening the pencil. When in use, rotate the gear to lift the top cover, insert the pencil, and then squeeze the pencil sharpener several times to complete the work of sharpening the pencil. The one-handed push-type pencil sharpener avoids the problems of "must operate the pencil sharpener with both hands" and "difficult to fix the pencil sharpener" in other types of pencil sharpeners, and solves the difficulties of special people when sharpening pencils. A whole new user experience.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. Although the utility model will be described in conjunction with preferred embodiments, it should be understood that it does not mean that the utility model is limited to the embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

As shown in Fig. 1, the one-handed push-type pencil sharpener combined structure of this embodiment includes: a top cover 9, a gear 7, a rack 2, a dust-proof compartment 6, a coiler 5, a central connection gear 4, a plastic shell, Extrusion part 1, torsion spring 3 and dust box 10; said ascending gear 7 is placed in the groove 8 of the plastic shell, interlocks with ascending rack 2, and rack 2 is connected with top cover 9 at the same time. The top of the top cover 9 has a bayonet socket for putting in a pencil; the dust-proof interlayer 6 is a cylindrical hollow structure, which is set on the outside of the coiler 5; the coiler 5 and the dust-proof interlayer 6 are stuck on the central connection gear 4; The extruded part 1 and the plastic shell together form the shell of the pencil sharpener, and the middle of the extruded part 1 is embedded with the rack 2, and the rack 2 is connected with the intermediate gear 7.

When in use, turn the gear 7, the rack 2 connected with the top cover 9 will rise, and then insert the pencil into the top opening. When sharpening a pencil, hold the sharpener in the palm of your hand and squeeze the extrusion parts 1 located on both sides towards the center. After being squeezed again, the shrinkage of the extruded part 1 will drive the movement of the rack 2, so that the rack 2 is pushed close to the central connection gear 4. The central connection gear 4 therefore rotates, and drives the rotation of the curling knife 5 simultaneously, thereby begins to sharpen the pencil. The remaining shavings and lead ash of the pencil sharpener can be blocked inside by the dustproof interlayer 6, and fall into the dust bag 10. The pencil sharpening can be completed by repeatedly extruding the extruding part 1.

After completing the pencil sharpening, the dust bag 10 can be taken out from the bottom by opening the cover for cleaning.

The appearance of the complete combined structure of the pencil sharpener is shown in Figure 6.
