It is cumbersome that yet the chip of existing pencil sharpener band is collected the box folding; Be the disclosed a kind of pencil sharpener that has box of Chinese patent of CN201338489Y like Granted publication number; Comprise the box body that is socketed to form by cover and end box; Be provided with the tool-post structure of blade and pen-rolling hole, the cover lower surface is provided with the draw-in groove that can match with tool-post structure, and tool-post structure is socketed in the draw-in groove.During use, the pen bits are deposited in the box body, in the time of still need toppling over the pen bits when box body is full or in the use, the operation of folding box body is cumbersome, gives to have used and has brought inconvenience.

The utility model content

The utility model technical problem to be solved provides a kind of folder formula pencil sharpener, can topple over the pen bits through the mode of pushing loam cake, and is easy to operate.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of folder formula pencil sharpener; Comprise base, be fixed on the interior cutter core of said base, it is characterized in that: also comprise with said base composition being used to hold a loam cake of the container of bits; The rear portion of said loam cake is and can be hinged on the said base press-startedly, and the aft bulkhead of said base or said loam cake is provided with the pencil import and export that are communicated with said cutter core.

According to an aspect of the utility model, the rear portion of said base bilateral wall is respectively equipped with the bearing pin that extends internally, and covers the position corresponding with said bearing pin on said and is provided with the axis hole that supplies said bearing pin to pass, and two arms of torsion spring are located in respectively on the said bearing pin.Pour out for the pen bits through pushing the front portion of lifting loam cake, and get back to initial position through the reset force of torsion spring.

The rear portion of said loam cake is provided with the convexity that is used to increase friction, pushes loam cake when user-friendly.

According to another aspect of the utility model, the rear portion of said base bilateral wall is respectively equipped with groove, covers on said with the corresponding position of said groove and is provided with the rotating shaft with said groove coupling, and said rotating shaft places in the said groove.Pour out for the pen bits through pushing the front portion of lifting loam cake, and get back to initial position through the gravity of self.

The rear portion of said loam cake and the two side of said base are provided with the convexity that is used to increase friction, push loam cake when user-friendly and grip pencil sharpener.

Compared with prior art; The advantage of the utility model is: be employed in hinged loam cake on the base that is fixed with the cutter core; Formed a container that is used to hold the pen bits with base, and owing to be hinged, the rear portion that only need push loam cake just can be opened this container and toppled over the pen bits; And need not the operation that both hands are dismantled lid and so on, use very convenient.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment 1

Referring to Fig. 1-Fig. 3, according to a kind of folder formula pencil sharpener of first embodiment of the utility model, comprise base 1 and be hinged on the loam cake 2 on the base 1 that cutter core 3 is fixed in the base 1.Base 1 aft bulkhead is provided with pencil and imports and exports 11, is communicated with the pen-rolling hole 31 of cutter core 3.

The rear portion of base 1 two side is respectively equipped with the bearing pin 12 that extends internally, and is provided with axis hole 21 with bearing pin 12 corresponding positions on the loam cake 2, passes for bearing pin 12 and realizes the hinged of base 1 and loam cake 2, forms folder formula structure thus.Two arms 41 of torsion spring 4 are located in respectively on the bearing pin 12, and loam cake 2 is passed in its rear end.The rear portion of loam cake 2 is provided with the convexity 22 that is used to increase friction, so that push loam cake 2 when using.

When needs cutting pencil; Pencil is imported and exported 11 through pencil extend in the pen-rolling hole 31 of cutter core 3 and cut, this moment, the pen bits were deposited in the container that base 1 and loam cake 2 form, in the time of need toppling over the pen bits when container in the full or use; The rear portion that only need push loam cake 2 is referring to Fig. 4.Because base 1 is hinged with loam cake 2, then this moment loam cake 2 the front portion lift and form crumb mouth 13, pen is considered thus crumb mouth 13 to be worth doing and is poured out.After having toppled over the pen bits, because the reset force of torsion spring 4, upwards lift thus at the rear portion of loam cake 2, and the front portion of loam cake 2 falls sealing crumb mouth 13.

Embodiment 2

Referring to Fig. 5-6, according to a kind of folder formula pencil sharpener of second embodiment of the utility model, comprise base 1 ' and be hinged on the loam cake 2 ' on the base 1 ' that cutter core 3 ' is fixed in the base 1 '.Loam cake 2 ' aft bulkhead is provided with pencil and imports and exports 21 ', is communicated with the pen-rolling hole 31 ' of cutter core 3 '.

The posterior medial of base 1 ' two side is respectively equipped with groove 11 '; Loam cake 2 ' goes up and groove 11 ' the corresponding position is provided with outward extending rotating shaft 22 '; Groove 11 ' preferably with the circle of rotating shaft 22 ' coupling; Not only be convenient to rotating shaft 22 ' and rotated within it but also make things convenient for rotating shaft 22 ' location, formed folder formula structure thus.The rear portion of loam cake 2 ' and the two side of base 1 ' are provided with the convexity 4 ' that is used to increase friction, conveniently to push and to grip when using pencil sharpener.Alternately, also can groove 11 ' be located at the outside of sidewall, rotating shaft 22 ' then extends internally and places in the groove 11 '.

When needs cutting pencil; Pencil is imported and exported 11 ' through pencil to extend in the pen-rolling hole 31 ' of cutter core 3 ' and cuts; This moment, the pen bits were deposited in the container of base 1 ' and loam cake 2 ' composition; In the time of need toppling over the pen bits when container in the full or use, the rear portion that only need push loam cake 2 ' is referring to Fig. 7.Because base 1 ' is hinged with loam cake 2 ', then this moment loam cake 2 ' the front portion lift and form crumb mouth 12 ', pen is considered thus crumb mouth 13 ' to be worth doing and is poured out.After having toppled over the pen bits, the front portion of loam cake 2 falls sealing crumb mouth 12 ' under the gravity effect.

The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection domain of the utility model.
