Abstract
The utility model relates to a screw-blade pencil sharpener, comprising a plastic knife seat and a screw blade, wherein a conical sharpening hole is arranged in the plastic knife seat, the side surface of the sharpening hole is provided with a chip removal seam, and the plastic knife seat is provided with the screw blade near the chip removal seam. The upper end and the lower end of the screw blade are respectively provided with a locating slot, and the locating slot of the lower end has no a buckling function and only is a process slot in blade manufacturing. The screw blade is fixed on the plastic knife seat by a knife-buckling slot and a buckling device. The screw-blade pencil sharpener has the advantages that the structure adopts a simple plastic component structure and a single-edge blade, and no screw is used for fixing, so the trouble that a common pencil sharpener must use the screw is avoided, and the cost is saved; the labor is saved on function, a pencil lead is not easily broken, and the pencil lead consumption is saved; from the mechanical structure, the blade breaks through the design of the traditional pencil sharpener, and the cutting force adhering to the pencil lead is fully decomposed, so the pencil lead has soft stress and is not easily cut off or broken.
Description
Technical field
The utility model relates to a kind of screw blade pencil sharpener.
Background technology
The market mainly contains two kinds of pencil sharpener cored structures at present, is respectively circular knife blade milling cutter pencil sharpener core peace cutter single blade pencil sharpener core.The former advantage cutting effect is good, and the shortcoming volume is big, and the cost height uses and carry all inconveniences; Latter's advantage is simple in structure, and cost is low; Easily disconnected pen core when shortcoming is cutter cutting pencil causes waste.
The utility model content
The purpose of this utility model provides a kind of screw blade pencil sharpener, has overcome that the pencil sharpener core volume was big in the past, and the cost height uses and carries all inconvenient or an easily disconnected core and to eat meat many, the shortcoming of waste resource when cutting.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of screw blade pencil sharpener, comprise plastics tool rest and screw blade, be provided with taper in the described plastics tool rest and cut a hole, the side of cutting a hole is provided with the chip removal seam, be provided with screw blade near chip removal seam place on the plastics tool rest, it is characterized in that: the two ends up and down of described screw blade are respectively equipped with locating slot, the plastics tool rest is provided with swaging clamp groove and the positioner that matches with locating slot, and screw blade is fixed on the plastics tool rest by swaging clamp groove and positioner.
The beneficial effects of the utility model are: adopted simple plastic part structure and hilted broadsword angle of throat sheet on the structure, need not screw and fix, removed the trouble technology that general pencil sharpener will be tightened up a screw from, saved cost; Laborsaving on the function, pen core is frangibility not, has economized the consumption of pencil-lead, and blade has been broken through conventional roll graver design from mechanical structure, has fully decomposed the cutting force that is attached on the pen core, makes that pen core is stressed softly to be not easy to be cut disconnected or to fracture.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation view of the described screw blade pencil sharpener of the utility model embodiment; Fig. 2 is the structural representation view of the screw blade of the described screw blade pencil sharpener of the utility model embodiment; Fig. 3 is the structural representation view of the plastics tool rest of the described screw blade pencil sharpener of the utility model embodiment; Fig. 4 is the structural representation view of the described screw blade pencil sharpener of the utility model embodiment.
Among the figure: 1, plastics tool rest; 2 screw blades; 3, locating slot; 4, chip removal seam; 5, positioner; 6, cut a hole; 7, swaging clamp groove.
The specific embodiment
Shown in Fig. 1-4, the described a kind of screw blade pencil sharpener of the utility model embodiment comprises plastics tool rest 1 and screw blade 2, is provided with taper in the described plastics tool rest 1 and cuts a hole 6, the side of cutting a hole 6 is provided with chip removal seam 4, stitches 4 places near chip removal on the plastics tool rest 1 and is provided with screw blade 2; The two ends up and down of described screw blade 2 are respectively equipped with locating slot 3, plastics tool rest 1 is provided with swaging clamp groove 7 and the positioner 5 that matches with locating slot 3, the locating slot 3 of described screw blade 2 lower ends is not have the screens function, operation groove when just making blade, swaging clamp groove 7 wraps up screw blade 2 lower ends fully, do not allow screw blade 2 displacement or on turn over, screw blade 2 is fixed on the plastics tool rest 1 by positioner 5 simultaneously, removed the trouble technology that general pencil sharpener will be tightened up a screw from, save cost waste material resource not again, be used for common pencil sharpener and electronic pencil sharpener not only can reduce cost, reach the effect of circular knife blade milling cutter pencil sharpener again, be applied to the pencil sharpener industry and be not only save resource but also environmental protection.
