Abstract
An improved cutting tool structure for pencil sharpener comprises a pedestal, a cutter and a shaft sleeve and is characterized in that, a pencil insert section is arranged at one end of the pedestal; a shaft rod is arranged at the other end thereof; a long hole is formed on one side face of the pencil insert section; two corresponding lugs respectively extend from one side of the pedestal in positions close to both ends; the cutter is arranged between the two lugs and parallel to the pedestal and is provided with a spiral cutting section and a gear section arranged at one end of the spiral cutting section; and the shaft sleeve is movably combined with the shaft rod of the pedestal and a ring tooth section engaged with the gear section of the cutter is arranged on the inner surface of the shaft sleeve. The cutting tool structure can increase the contact area between the ring tooth section of the shaft sleeve and the gear section at one end of the cutter, thus improving the structure strength of the cutting tool. Accordingly, the cutting tool structure can bear larger rotation gravity during use, thus prolonging the service life of the cutter tool for the pencil sharpener.
Description
Technical field
The utility model relates to a kind of cutter structure of pencil sharpener, refers to a kind of cutter structure of modified pencil sharpener especially.
Background technology
The pencil sharpener cutter (as shown in Figure 1) of general usefulness, comprise a pedestal 4 with penholder portion 41, one side of said pedestal 4 is provided with a mobilizable circular knife portion 5 of tilting, one end of said circular knife portion 5 is provided with a gear 51, and said pedestal 4 activities are incorporated in the axle sleeve 6, and the inner face of said axle sleeve 6 is provided with the circular tooth part 61 that meshes with gear 51; Thus, can cooperate with required pencil sharpener, allow pencil insert penholder portion 41 after, rotate said pedestal 4, make said pedestal 4 drive circular knife portions 5, allow the gear part 51 of circular knife portion 5 one ends on the circular tooth part 61 of axle sleeve 6 around rotation, by the pencil in the 5 rotary cut penholder portions 41 of circular knife portion.
Though the cutter of above-mentioned pencil sharpener commonly used can reach the effect of rotary cut pencil, but because said circular knife portion 5 is sides that are obliquely installed at pedestal 4, therefore, when circular tooth part 61 engagements of the gear 51 of said circular knife portion 5 one ends and axle sleeve 6, the two contact area of said gear 51 and circular tooth part 61 is less, the occlusal surface B deficiency that causes gear 51 and circular tooth part 61, can't obtain preferable support, make that the structural strength of said cutter is relatively poor, and cause circular tooth part 61 can't bear bigger rotational gravity under long-term use, thereby the situation of wearing and tearing takes place.
Therefore the cutter of known pencil sharpener exists the problem that above-mentioned wearing and tearing cause the weak point in service life.
Summary of the invention
Main purpose of the present utility model is to be to overcome the deficiencies in the prior art, and a kind of cutter structure of modified pencil sharpener is provided, and increases the circular tooth part of axle sleeve and the contact area of sharpener one end gear part, to promote the structural strength of cutter.
The technical scheme that the utility model addresses the above problem is: a kind of cutter structure of modified pencil sharpener, comprise pedestal, sharpener and axle sleeve, it is characterized in that: an end of described pedestal is provided with a penholder portion, the other end is provided with an axostylus axostyle, one side of said penholder portion is provided with a slotted hole, and the position of contiguous two ends of said pedestal one side is extended corresponding two lugs respectively; Described sharpener is located between said two lugs and is parallel with said pedestal, also is provided with a circular knife portion and is located at the gear part of circular knife portion one end; Described axle sleeve combines with the axostylus axostyle activity of described pedestal, and the inner face of said axle sleeve is provided with the circular tooth part with the engagement of the gear part of sharpener.
The past axostylus axostyle direction of described penholder portion is gradually-reducing shape.
Be respectively equipped with a perforation on described two lugs.
The centre of described sharpener is provided with the movable respectively axle on described two lugs of two ends.
The advantage of the utility model tool is to increase the circular tooth part of axle sleeve and the contact area of sharpener one end gear part, promotes the structural strength of cutter, thereby can bear bigger rotational gravity in use, reaches the service life that prolongs the pencil sharpener cutter.
Description of drawings
Fig. 1 is the state generalized section of the cutter structure of the pencil sharpener used always.
Fig. 2 is a three-dimensional appearance schematic diagram of the present utility model.
Fig. 3 is a perspective exploded view of the present utility model.
Fig. 4 is a state generalized section of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is illustrated further.
See also shown in Fig. 2～4, Fig. 2～4 are respectively three-dimensional appearance schematic diagram of the present utility model, perspective exploded view of the present utility model and state generalized section of the present utility model.Shown in Fig. 2～4, the cutter structure of a kind of modified pencil sharpener of the present utility model comprises a pedestal 1, a sharpener 2 and an axle sleeve 3.
One end of described pedestal 1 is provided with a penholder portion 11, the other end is provided with an axostylus axostyle 12, described penholder portion 11 is a gradually-reducing shape toward the axostylus axostyle directions, and a side of described penholder portion 11 is provided with a slotted hole 111, and the position of contiguous two ends of described pedestal 1 one sides is extended corresponding lug 13 respectively, is respectively equipped with a perforation 131 on each lug 13.
The centre of described sharpener 2 is provided with axle 21, two ends of described axle 21 are located at respectively in the perforation 131 of described two lugs 13, make described sharpener 2 activities between two lugs 13 and parallel, and described sharpener 2 is provided with a circular knife portion 22, an and gear part 23 that is located at described circular knife portion 22 1 ends with pedestal 1.
When the utility model is used, can be arranged on the pencil sharpener of electrodynamic type or hand, and make described pedestal 1 be connected (not shown) with power-jdriven gear or wind.When using, pencil is inserted in the penholder portion 11, rotate pedestal 1 again, make pedestal 1 drive the sharpener 2 of one side, allow the gear part 23 of sharpener 2 one ends on the circular tooth part 31 of axle sleeve 3 around rotation, to utilize circular knife portion 22 on the described sharpener 2 to carry out the rotary cut of pencil in the penholder portion 11 by slotted hole 111, and owing to described sharpener 2 cooperates two lugs 13 and is parallel shape with pedestal 1, make the gear part 23 of described sharpener 2 one ends be meshing with each other with the circular tooth part 31 of bigger contact area and axle sleeve 3, by increasing the occlusal surface A between gear part 23 and the circular tooth part 31, make sharpener 2 can bear bigger rotational gravity when rotating, thereby can promote the structural strength of described cutter.
In sum, the cutter structure of modified pencil sharpener of the present utility model can increase the circular tooth part of axle sleeve and the contact area of sharpener one end gear part, by promoting the structural strength of cutter, thereby can bear bigger rotational gravity in use, reach the service life that prolongs cutter.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique under the situation that does not break away from spirit and scope of the present utility model, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
