Description
Technical field
The utility model belongs to field of mechanical technique, be related to a kind of pencil sharpener more particularly to a kind of pencil sharpener it is automatic into
Move back pen device.
Background technique
Nowadays, automatic pencil sharpener is used by more and more people, and requirement of the people for pencil sharpener ease for use is also got over
Come higher, the pencil sharpener on existing market, which is substantially all, thus has had automatic entrance-exit function.Such as application No. is
A kind of automatic pencil sharpener disclosed in 201420437278.0 into pen device, it includes that bracket, turning wheel and two axis connect
Installation axle on bracket is successively arranged with gear and idler wheel in two installation axles, and the gear in two installation axles is centrosymmetric,
Gear is engaged with the rack gear on turning wheel, idler wheel and gear respectively with installation axle clearance fit, when turning wheel rotation, gear to
Idler wheel is mobile and presses with a side of idler wheel, and two idler wheels are close to each other and are clamped in pencil side, while two idler wheels exist
It is rotated under the frictional force effect of corresponding gear, it in this way will be by pencil under the action of two frictional force between idler wheel and pencil
It is automatically fed into penknife and planes.
However the automatic pencil sharpener into pen device or using similar structures inlet duct all there is it is identical not
Foot place: the spacing between two installation axles is fixed and invariable, so that the spacing between two idler wheels is also to immobilize and nothing
Method is adjusted, and is also fixed and invariable to be formed by the space passed through for pencil between two idler wheels, this is thus caused to fill into pen
It sets and is only applicable to be formed by the pencil that space matches between two idler wheels, i.e., be only applicable in a kind of pencil of specification, therefore suitable
It is poor with property.
Summary of the invention
The purpose of this utility model be in view of the above-mentioned problems existing in the prior art, propose a kind of pencil sharpener it is automatic into
Pen device is moved back, the technical problem to be solved is that how to improve applicability, meets the automatic entrance-exit pen of different size pencil.
The purpose of this utility model can be realized by the following technical scheme:
The automatic entrance-exit pen device of pencil sharpener, including fixed frame and on the inside of the fixed frame and the turntable that can rotate,
It is provided through channel on the turntable, is arranged in parallel with two shafts on fixed frame at passway, is covered in two shafts
It is connected to castle wheel and pen feeding wheel, two castle wheels are set to the opposite end of two shafts, two castle wheels can be driven to rotate when turntable rotation
And along place shaft it is close to each other or separation, and when two castle wheels mutually close to when two pen feeding wheels can be pushed close to each other and turn
It is dynamic, which is characterized in that this automatic entrance-exit pen device further includes damper box, and fixed frame is fixed in damper box, and damper box is equipped with
The through-hole opposite with channel is equipped with the adjustment disk being able to rotate in damper box, is respectively connected in two shafts mutually fixed with adjustment disk
