Description
Technical field
The utility model relates to a kind of pencil sharpener, and what especially relate to a kind of pencil sharpener advances pen device automatically.
Background technology
Traditional pencil sharpener generally includes organism; Be provided with a hand at the rear side of body and induce clamper; The clamper of inducing that draws back in advance towards the body rear capable of using of waiting to sharpen a pencil grips; And when swing handle rotates, induce clamper can be constantly towards body by giving, be fed on the position of cutting waiting to sharpen a pencil.At the state of inducing clamper to be in to draw back, but when also not having clamping to be sharpened a pencil, when swing handle during by turn automatically closing make that at the body rear user's hand is crushed.
For this reason; Someone has designed a kind of by name: the patent of " pencil sharpener and a tool feed mechanism thereof " (Chinese patent number: 200720176514.8); It includes the fixed mount that can be installed in the pencil sharpener body, be combined on the fixed mount and can be with respect to a rotating disk of fixed mount rotation, and is hubbed on the fixed mount and maintains each other and can sleeve of pen be held several feedback wheel shafts of the spacing of passing through; When rotating disk rotated through driving, a feedback wheel shaft also can be driven synchronously, so will in pencil sharpener, presenting feeding via the tool that a feedback wheel shaft grasps, to carry out stock removal action.This design has solved traditional pencil sharpener predisposition preferably and led the technical problem that clamper possibly crush user's hand, and is simple in structure, easy to use, therefore obtains the extensive approval in market.
But, to cut in the process actual, a feedback wheel shaft rotates under the driving of rotating disk; Even after pencil sharper has been got well; Pencil is not cut if the user feels this moment, continues to make dial rotation, and a feedback wheel shaft still can drive pencil and inwardly advance pen; Make that pencil is excessively cut, cause unnecessary waste.
Summary of the invention
The purpose of the utility model be a kind of pencil sharpener is provided for the deficiency that solves above-mentioned existence advance pen device automatically, through spring is set, and make that pencil can stop to cut after cutting between rotating disk and fixed mount, prevent that pencil from excessively being cut.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of pencil sharpener advance pen device automatically; Comprise fixed mount and the rotating disk that which is provided with, offer sleeve joint hole on the fixed mount, rotating disk is provided with axle sleeve; Described axle sleeve is located in the sleeve joint hole rotationally; Also be articulated with gear shaft on the fixed mount, gear shaft rotates under can driving in the rotation of rotating disk, it is characterized in that: be arranged with spring on the described axle sleeve and between rotating disk and fixed mount.During use; The utility model and body, cut the assembling of set of knives and swing handle, swing handle drives and cuts set of knives and rotate, and cuts set of knives and drives axle sleeve and dial rotation; The rotating disk gear shaft is rotated; Gear shaft drives pencil motion in the body, when pencil touches when cutting set of knives, cuts set of knives pencil is cut.After pencil sharper was good, pencil withstood and cuts set of knives, at this moment; Have bigger resistance on the pencil, gear shaft is owing to having frictional force thereby also have bigger resistance with pencil, owing to be arranged with spring between rotating disk and the fixed mount; When gear shaft receives big resistance when motionless, contact with gear shaft in the dial rotation process and receive reaction force, and then compress spring; Make to occur skidding between rotating disk and the gear shaft that pencil advances pen no longer inward, effectively protect pencil excessively not cut.
As preferably, described rotating disk is provided with bulge loop, and bulge loop is positioned at axle sleeve one side and with the outside that is located in axle sleeve, the maximum gauge of said spring is less than the diameter of bulge loop.Bulge loop be provided with the non axial shift position that is beneficial to restraining spring, guarantee the stability of product structure.
