It is dynamic to be equipped with the first sliding block and the second sliding block.
First sliding block and the second sliding block are respectively equipped with the first positioning column and the second positioning column, and the top base is equipped with the
Three positioning columns and the 4th positioning column.
First spring one end is connect with the second positioning column, and the other end is connect with third positioning column, the second spring
One end is connect with the first positioning column, and the other end is connect with the 4th positioning column.
First sliding block is equipped with the first locating slot with the cooperation sliding of the first track, and second sliding block is equipped with and second
Second locating slot of track cooperation sliding.
First slider bottom is equipped with the first rack gear, and second slider bottom is equipped with the second rack gear.
The top base rotation is equipped with gear wheel, first rack gear and the second rack gear and engages simultaneously with gear wheel.
First sliding block and the second sliding block are respectively equipped with the identical locking card slot of shape.
The locking card slot is equipped with guiding surface, and setting guiding surface is conducive to preferably strut 2 cunnings when pencil insertion
Block.
Using the above structure, the utility model has the following advantages that compared with prior art, in use, pencil insertion first
Between sliding block and the second sliding block, strut the two, since 2 sliding blocks are engaged each by rack gear with gear wheel, so both sides are torn open
The distance opened must be the same, and the positioning of prior art three-jaw may be filled in pencil position deviation itself and grab lead
The power of hand influences and not can guarantee the accurate generation bias of centering, after the complete extraction of pencil sharper, passes through the first spring and second
Spring force plus gear wheel guidance under so that the first sliding block and the second sliding block return is offseted again.The utility model uses gear
The connection type of rack gear, the relatively reliable stabilization of structure, and also centering is more accurate, and this structure can be with application diameter difference
Pencil, and avoid the prior art need Manual press open three-jaw the step of.

Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Locking mechanism in a kind of gear mesh, including the first spring 12, second spring 13, top base 7, be parallel to each other and be fixed on
The first track 8 and the second track 9 of top base 7, first track 8 and the sliding of the second track 9 are equipped with the first sliding block 10 and the
Two sliding blocks 11.
First sliding block 10 and the second sliding block 11 are respectively equipped with the first positioning column 14 and the second positioning column 15, the upper base
Seat 7 is equipped with third positioning column 16 and the 4th positioning column 17.
Described first spring, 12 one end is connect with the second positioning column 15, and the other end is connect with third positioning column 16, and described
Two springs, 13 one end is connect with the first positioning column 14, and the other end is connect with the 4th positioning column 17.
First sliding block 10 is equipped with the first locating slot 18 with the cooperation sliding of the first track 8, and second sliding block 11 is set
There is the second locating slot 19 with the cooperation sliding of the second track 9.
First sliding block, 10 bottom is equipped with the first rack gear 20, and 11 bottom of the second sliding block is equipped with the second rack gear 21.
The top base 7 rotation be equipped with gear wheel 22, first rack gear 20 and the second rack gear 21 simultaneously with gear wheel 22
Engagement.
First sliding block 10 and the second sliding block 11 are respectively equipped with the identical locking card slot 28 of shape.
The locking card slot 28 is equipped with guiding surface 29, and setting guiding surface 29 is conducive to preferably strut when pencil insertion
2 sliding blocks.
Using the above structure, the utility model has the following advantages that compared with prior art, in use, pencil insertion first
Between sliding block 10 and the second sliding block 11, strut the two, since 2 sliding blocks are engaged each by rack gear with gear wheel, so two
While the distance dismantled must be it is the same, and the positioning of prior art three-jaw may be filled in pencil position deviation itself and
The power for grabbing pencil hand influences and not can guarantee the accurate generation bias of centering, after the complete extraction of pencil sharper, passes through the first spring 12
Add with 13 elastic force of second spring makes the first sliding block 10 and 11 return of the second sliding block offset again under the guidance of gear wheel 22.This reality
With the novel connection type using rack-and-pinion, the relatively reliable stabilization of structure, and centering is more accurate, and this structure can
With the different pencil of application diameter, and avoid the step of prior art needs Manual press to open three-jaw.
2 lockings card slot 28 forms ellipse or diamond shape close to rear.
