Abstract

The utility model relates to a pencil sharpener, belonging to the technical field of school supplies. A multifunctional pencil sharpener comprises a frame, wherein a planer tool is inlaid in one side of the frame; the other side of the frame is provided with a first groove and a second groove; the lower side of the planer tool is provided with a first pencil sharpener rest and a second pencil sharpener rest respectively; the first pencil sharpener rest is provided with a short blade; the second pencil sharpener rest is provided with a curve blade; and an included angle between the curved blade and a horizontal line is between 3 and 5 DEG. According to the multifunctional pencil sharpener, two kinds of blades are arranged in the same frame, so that square pencil points can be sharpened, pencil points with different lengths and different gradients can be sharpened as required, and the pencil sharpener greatly facilitates work and study of people and saves time and labor.

Description

A kind of multi-functional pencil sharpener

Technical field

The utility model relates to pencil sharpener, belongs to the study article technical field.

Background technology

At present, all kinds of examinations or other place pencil commonly used to square nib, existing on the market have the propelling pencil of square nib and a common pencil of circular nib; Uses common pencil generally all need roll up and cut, but the nib that common pencil sharpener rolls out all is circular that very difficult volume is cut out square nib with pencil sharpener; Waste time and energy, as shown in Figure 9 in addition because ordinary blade is all long, and do not have flexibility; So the nib that this pencil sharpener rolls out is too short, sharp excessively, is inconvenient to use.

Summary of the invention

The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, can rolls up the multi-functional pencil sharpener of the circular nib of cutting out square nib and having gradient.

The utility model is realized through following technical scheme:

A kind of multi-functional pencil sharpener; Its special character is to comprise framework 1, and framework 1 one sides are inlaid with planing tool 2, and framework 1 opposite side has first groove 7 and second groove 8; The below of planing tool 2 is respectively arranged with the first volume graver frame 3 and the second pencil sharpener frame 5; Be equipped with on the first volume graver frame 3 on shortened cutting blade 4, the second pencil sharpener framves 5 curved blades 6 is installed, curved blades 6 is 3-5 ° with horizontal angle.

The multi-functional pencil sharpener of the utility model is provided with two kinds of blades in same framework, so both can roll up and cut out square nib, also can roll up the nib of cutting out different length and different gradients as required, greatly facilitates people's work and study, and is time saving and energy saving.

The specific embodiment

Provide the specific embodiment of the utility model below with reference to accompanying drawing, be used for the formation of the utility model is done further explain.

Embodiment 1

The multi-functional pencil sharpener of present embodiment with reference to figure 1-7, comprises framework 1; Framework 1 one sides are inlaid with planing tool 2; Framework 1 opposite side has first groove 7 and second groove 8, and the below of planing tool 2 is respectively arranged with the first volume graver frame 3 and the second pencil sharpener frame 5, on the first volume graver frame 3 shortened cutting blade 4 is installed; On the second pencil sharpener frame 5 curved blades 6 is installed, curved blades 6 is 3 ° with horizontal angle.

Operating procedure: 1. operating personnel at first are placed on pencil to roll up on first knife rest and cut, and the nib shape that volume is cut out is as shown in Figure 5; 2. pencil is placed in first groove again, pen core is placed on the planing tool two corresponding surfaces to pen core planes repeatedly, the nib shape of producing is as shown in Figure 6; 3. will go up the pencil that a step processes again and be placed in second groove, and pen core will be placed on the planing tool two other corresponding surface to pen core plane repeatedly, the nib final form that processes is as shown in Figure 7, is square nib.

Embodiment 2

The structure of the multi-functional pencil sharpener of present embodiment is the same with embodiment 1; With reference to figure 1-4, Fig. 8; When different is to use pencil is placed directly in to roll up on second knife rest and cuts, the nib shape that volume is cut out is as shown in Figure 8, and the nib shape is more mellow and fuller; Suitable length, rather than the point of cutting out like ordinary blade volume so, short.

The multi-functional pencil sharpener of above embodiment is provided with two kinds of blades in same framework, so both can roll up and cut out square nib, also can roll up the nib of cutting out different length and different gradients as required, greatly facilitates people's work and study, and is time saving and energy saving.

Claims
