Abstract

The utility model relates to a pencil clamping device for the pencil sharpener that comprises a pencil clamping back cover, a pencil clamping turnplate with an operation handle and a pencil clamping front cover buckled on the pencil clamping back cover; wherein, the pencil clamping back cover, the pencil clamping turnplate and the pencil clamping front cover are provided with a through hole for passing of the pencil. The utility model is characterized in that: the pencil clamping back cover is provided with a bulge loop taking a pencil hole as the center; the edge wall of the disc type pencil clamping turnplate is buckled on the bulge loop and oriented; three clamping blocks are orientated between the pencil clamping turnplate and the pencil clamping back cover and are in linkage with the pencil clamping turnplate and are evenly arranged around the pencil hole on the pencil clamping back cover; and a returning spring is arranged between the pencil clamping turnplate and the pencil clamping back cover. Edge wall of the pencil clamping turnplate is buckled on the bulge loop of the pencil clamping back cover taking the bulge loop as an axis, thus the cooperating area is large, the coaxial degree is good during rotating and disadvantage of partial abrasion is unlikely to exist; besides, the three clamping blocks are arranged between the pencil clamping turnplate and the pencil clamping back cover, thus the integrity is stronger, the pencil can be clamped more stably and a smaller pencil point can be sharpened.

Description

The penknife pencil holding mechanism

Technical field:

The utility model relates to the stationery field, particularly a kind of improvement of penknife pencil holding mechanism.

Background technology:

Existing penknife comprises being built-in with cuts the support that pen revolves cutter, pencil holding mechanism, pencil holding mechanism is by the pen clip bonnet, ribbon gymnastics is made a spindle clamp rotating disk and is formed with the pen clip protecgulum that is fastened on the pen clip bonnet, the pen clip bonnet, offer the through hole that pencil passes on pen clip rotating disk and the pen clip protecgulum, the pen clip bonnet is evenly equipped with three projections around the pencil hole, the pen clip rotating disk is set on three projections and locatees, and can do the rotation of certain angle around three projections, be provided with the arcuation back-moving spring between pen clip rotating disk and pen clip bonnet, three clamp block teeth and are positioned on three projections, it is provided with a protruding axle towards pen clip rotating disk one side, protruding axle can insert in the pen clip rotating disk breach, the spinning movement of pen clip rotating disk can drive three clamping block teeth and rotate around positioning convex column separately synchronously, and the pen clip protecgulum be located on the pen clip bonnet three clamping block teeth and pen clip rotating disk are clipped in wherein location.The pen clip bonnet is provided with two to three pins backwards, and pin inserts in the support, and is arranged with spring on pin, and spring one end contacts in the support inboard, pencil holding mechanism is remained be close to support; During work, pulling lever that the pen clip rotating disk exposes rotates an angle with the pen clip rotating disk and spurs pencil holding mechanism and leave support one spacing, described pen clip rotating disk drives three clamping block teeth and opens, and revolves the cutter place until support in the reservation pencil hole of inserting panel, pen clip rotating disk and pen clip bonnet of waiting to sharpen a pencil; Shed external force, the pen clip rotating disk drives three clamping block teeth and clamps pencil shaft under the effect of back-moving spring, and revolving cutter can ream the pencil surface of having good positioning, and in addition, pencil and pencil holding mechanism constantly go forward one by one under the effect of pin spring, till cutting.

Because its pen clip rotating disk of pencil holding mechanism of above-mentioned penknife is a laminated structure, and be positioned on the pen clip bonnet as pivot point by three projections, frequent use is very easily with three projections and the distortion of pen clip rotating disk contact surface abrasion, in addition, three clamp block teeth and also only are hung in the breach of pen clip rotating disk by short protruding axle, stressedly also easily deviate from, and then influence is normal uses.

Summary of the invention:

The purpose of this utility model is in order to overcome the deficiency of traditional penknife, and it is bigger to design a kind of pen clip rotating disk and pen clip bonnet mating surface, clamps block teeth and is located at penknife pencil holding mechanism between pen clip rotating disk and pen clip bonnet.

Task of the present utility model is finished like this: a kind of penknife pencil holding mechanism, comprise the pen clip bonnet, ribbon gymnastics is made a spindle clamp rotating disk and is fastened on pen clip protecgulum on the pen clip bonnet, the pen clip bonnet, offer the through hole that pencil passes on pen clip rotating disk and the pen clip protecgulum, it is characterized in that the pen clip bonnet is that the center is provided with a bulge loop with the pencil hole, the edge ring wall of discoid pen clip rotating disk be located on the bulge loop locatees, be positioned with three between pen clip rotating disk and pen clip bonnet with pen clip rotating disk interlock and be distributed on the clamping block teeth on pen clip bonnet pencil hole week edge, be provided with back-moving spring between pen clip rotating disk and pen clip bonnet.Pen clip rotating disk edge ring wall be located on the pen clip bonnet bulge loop, with the bulge loop be axle not only mating surface is bigger, axiality is good during rotation, and is not prone to the defective of concentrated wear, in addition then, three clamp block teeth and are located between pen clip rotating disk and pen clip bonnet, globality is strong.

The utlity model has compact conformation, reasonable in design, pen clip rotating disk and pen clip bonnet adopt the sleeve location, and axiality is good, rotate more flexibly, and the location clamps block teeth betwixt, the reliable in action that links, and pen clip is more firm, can cut a more pin of refinement.

Below in conjunction with concrete legend the utility model is described further.
