Abstract

A kind of pen tip thickness regulating mechanism of pencil sharpener, including knife rest, it shakes the hand, push rod and adjuster, knife rest is mounted on the front end shaken the hand and is fixed by gear ring, what push rod was axially movable runs through setting in shaking the hand, the front end of push rod is protruded into knife rest to limit the depth that pen tip protrudes into knife rest, adjuster is installed in rotation on rear end of shaking the hand, and it is coaxially disposed with push rod, in adjuster projection it is multiple have offset cooperation with the end of push rod, for adjusting the tooth position of push rod stroke, tooth position is alternatively arranged along arc-shaped, and tooth position height is gradually increased, adjuster is by rotating the adjusting for making the tooth position of different height and the inconsistent realization of push rod to push rod axial direction shift motion.The utility model is structurally reasonable compact, and operation is very easy, and rotary regulator is only needed to achieve that the adjusting for protruding into the position of knife rest to push rod, to realize that the thickness to pen tip after cutting is adjusted, compared with existing structure, the gear of adjusting is more, structure is simpler, operates also more convenient.

Description

A kind of pen tip thickness regulating mechanism of pencil sharpener

Technical field

The utility model relates to a kind of stationeries, and in particular to a kind of pen tip thickness regulating mechanism of pencil sharpener.

Background technique

Pencil sharpener cuts that the pen or shape tool is deep to be liked by students as a kind of, and pencil sharpener generally comprises main body, pencil holding mechanism, knife Frame and rocker arm, in use, pencil is fixed with pencil holding mechanism, pen can be cut by shaking with hands rocker arm.Traditional pencil sharpener cannot The thickness length of pen core is adjusted, the thickness for cutting pen tip after pen is the same.Also occurs adjustable pen tip at present The pencil sharpener of thickness, as " penknife directly pushes away two-level pen tip thickness tune for the Chinese patent of Patent No. 201711286308.7 Save mechanism and penknife ", it is by the clever structure cooperation between button, guide sleeve and guide rod, button is pressed by user's hand Press operation, by pushing a button to reach guide rod in two axial positions, i.e., the position under first state be pencil point compared with Position when thin；Position under second state is position when pencil point is thicker, and the position that push rod protrudes into knife rest is cut to limit The thickness of rear pencil point is cut, guide rod is fixed with the push rod that can limit pencil point thickness.This pencil sharpener passes through straight button push Mode meet the requirements of the thicker shelves of pencil point and the thinner shelves of pen tip, but it only has two gears, cannot as needed into Row is multistage to be adjusted.

Summary of the invention

Technical problem to be solved in the utility model is provided a kind of structurally reasonable tight for the above-mentioned state of the art Gather, the thickness of pen tip can be carried out multistage adjusting pencil sharpener pen tip thickness regulating mechanism.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of pen tip thickness of pencil sharpener is adjusted Mechanism, including knife rest, shake the hand, push rod and adjuster, knife rest are mounted on the front end shaken the hand and are fixed by gear ring, push rod can be moved axially Dynamic runs through setting in shaking the hand, and the front end of push rod is protruded into knife rest to limit the depth that pen tip protrudes into knife rest, and adjuster can turn It is mounted on rear end of shaking the hand dynamicly, and is coaxially disposed with push rod, it is characterised in that: the multiple ends having with push rod of projection in adjuster Offset cooperation, the tooth position for adjusting push rod stroke, and tooth position is alternatively arranged along arc-shaped, and tooth position height is gradually increased, and is adjusted Device is by rotating the adjusting for making the tooth position of different height and the inconsistent realization of push rod to push rod axial direction shift motion；

The adjuster is rotatably arranged in the rear end shaken the hand by cover board, and the rear end shaken the hand is equipped with circular concave, adjusts The front end face of section device is equipped with the convex edge that offsets with the rear end circular concave shaken the hand, cover board upper shield on the convex edge of adjuster with shake Hand is connected and fixed；

The convex edge of the adjuster is equipped with notch, is equipped with an elastic arm in the position of notch, is convexly equipped on elastic arm One stuck point, circumferential on the front end face of cover board to be equipped with multiple gear card holes with stuck point cooperation, adjuster passes through stuck point and gear card The multistage gear limit of rotation is realized in the cooperation in hole.

As an improvement, the adjuster is in the lid cap-like structure of front opening, the rear end being equipped in adjuster for push rod is inserted The stepped hole entered, tooth position are arranged circumferentially on the step surface of stepped hole in segmental arc, and the projection of rear end side and the tooth position of push rod offset Block, the rear portion of push rod, block front be equipped with a bulge loop, be arranged with a spring in the middle part of push rod, spring supporting is in bulge loop Front end and the inner wall shaken the hand between, there is push rod and move backward the trend to offset with adjuster always.

As an improvement, the tooth position is arranged on the step surface in adjuster in rotational symmetry in semicircular arc, after push rod The block at end is symmetrically arranged two.

Further, the tooth position is 6~10, and the number of gear card hole is identical as tooth position, and gear card hole is in semicircular arc Interval is uniformly distributed.

Further, the front edge of the cover board is equipped at intervals with several connection buckles, and the circular concave shaken the hand, which is equipped with, to be supplied The card hole of connection buckle insertion, cover board are connected and fixed by way of clamping with shaking the hand.

Finally, the outer surface of cover board is flush with rear end of shaking the hand after the cover board and connection of shaking the hand.

Compared with the prior art, the advantages of the utility model are: setting adjuster, it is equipped in adjuster and putting back-end The tooth position for contradicting cooperation is moved axially by the rotation forces push rod of adjuster, so that the depth that pen tip protrudes into knife rest is limited, it is real The thickness of existing pen tip is adjusted；Tooth position is multiple simultaneously, and the multistage of pen tip thickness may be implemented and adjust.The utility model is structurally reasonable Compact, operation is very easy, and rotary regulator is only needed to achieve that the adjusting for protruding into the position of knife rest to push rod, thus realization pair The thickness of pen tip is adjusted after cutting, and compared with existing structure, the gear of adjusting is more, and structure is simpler, and operation is also more square Just.
