CN2628284Y - Pencil sharpener - Google Patents

Abstract

The utility model relates to a multiple pencil sharpener comprising a chassis, a groove and knife blades. The characteristics lie in that the rectangular blade and the T-shaped blade are fixed on the chassis through a bolt and that the knife edges cling to the inclined tangent line of a taper hole. The groove on the chassis inosculates with the rectangular blade; the T-shaped blade is fixed on one side of the chassis. The utility model has simple structure and low cost and is easy to carry; when a pencil is sharpened, the pencil core is not easy to break.

Description

Compound pencil-knife

Technical field

The utility model relates to stationery, more specifically relates to a kind of compound pencil-knife

Background technology

Existing pencil-knife has two types: the first kind is a plain edition straight knife sheet pencil-knife, and the advantage of this cutter is small volume and less weight, and is easy to use, easy to carry, and production cost is low, and price is cheap, is suitable for the generality consumer.When weak point is to cut pencil, the pencil-lead easy fracture, sometimes in addition pencil sharper intact, do not cut one yet, cause the wasting of resources, reason is that the straight knife sheet makes pencil one side stressed, and pencil-lead is immalleable.Another kind of is the two-way rotating cam cutter of luxury handle type pencil-knife, and the advantage of this cutter is that cutting speed is fast, and is effective.But there are 3 deficiencies: the one, the production cost height, price is more expensive, and is general all more than 15-50 unit/only, unsuitable general consumer demand.The 2nd, pencil easily is cut too much, but the lead for retractable pencil length that causes is limited, easily causes the wasting of resources.The 3rd, volume is big, and heaviness is not portable.

Summary of the invention

The purpose of this utility model just is to overcome the shortcoming and defect that prior art exists, and inherits its advantage separately again.The purpose of this utility model is to provide a kind of compound pencil-knife, can not only save production cost relatively, knock down price, and when cutting continuous lead for retractable pencil, lead for retractable pencil cutting length can be controlled, easy to carry, cost is low.

The purpose of this utility model is achieved in that plain edition straight knife sheet is transformed into short rectangular blade, so both avoided pencil-lead to be fractureed because of immalleable.Only relate to the wooden part of pencil during cutting, lead for retractable pencil by Shape reed cutter cuts in the other direction, and lead for retractable pencil length, thickness are followed one's inclinations adjustable.

The utility model compared with prior art has the following advantages and effect: simple in structure, easy to make, cost is low, and when cutting continuous lead for retractable pencil, lead for retractable pencil thickness length is adjustable, and is easy to carry.

Description of drawings

Fig. 1 is compound pencil-knife structural representation.

Wherein: 1-pedestal, 2-conical bore, 3-groove, 4-blade, the screw of 5-fixed blade, 6-blade, 7-reed-type sharpener, 8-cutting mouth.

The specific embodiment

As shown in Figure 1, the utility model mainly is made up of the screw 5 of pedestal 1, fixed blade, conical bore 2, groove 3, blade 4, cutting mouthfuls 8, and the rectangular blade 4 that will punch with screw 5 is fixed on the pedestal 1 and gets final product.Pedestal 1 is trapezoidal, and blade 4 is rectangular, and its blade 6 parts are close on the line of cutting sth. askew of conical bore 2.Rectangular blade 4 is primarily aimed at the wooden partial design of flexible on the pencil; Reed-type Shape blade 7 is primarily aimed at the pencil-lead design of easy fracture.Reed-type

Shape blade 7 is fixed on the side of pedestal 1, and is relative with the rectangular blade edge of a knife.

Claims (2)

1, a kind of compound pencil-knife, it is made of pedestal (1), groove (3), it is characterized in that with screw (5) rectangle blade (4) being fixed on the pedestal (1), and blade (6) is close on the line of cutting sth. askew of conical bore (2), groove (3) on the pedestal (1) coincide with rectangular blade (4) The shape blade is fixed on pedestal (1) one side.

2, a kind of compound pencil-knife according to claim 1 is characterized in that pedestal (1) is trapezoidal, and blade (4) is rectangular, and blade (7) is
