Specific embodiment

The utility model embodiment discloses a kind of knife rest of pencil-knife, is equipped with briquetting, can prevent the knife of pencil-knife Piece end occurs Texturized, and then avoids occurring breaks down, pencil and breaks core and the problems such as knife rest damages.The utility model Embodiment also discloses a kind of pencil-knife, applies above-mentioned knife rest, can prevent the butt curl of blade from deforming, avoid occurring Breaks down, pencil break core and knife rest the problems such as damaging.

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

- Fig. 6 is please referred to Fig.1, the utility model embodiment provides a kind of knife rest of pencil-knife, including frame body 101 and pressure Block 102, frame body 101 are equipped with blade mounting surface 111；Briquetting 102 is fixed on frame body 101, and briquetting 102 is used to hold out against blade 103 end simultaneously makes the end of blade 103 be adjacent to blade mounting surface 111.

The knife rest that the utility model embodiment provides has briquetting 102, and briquetting 102 is used to hold out against the end of blade 103 simultaneously The end of blade 103 is made to be adjacent to blade mounting surface 111, can prevent the end of blade 103 from occurring when by the active force of pencil It is Texturized, and then avoid occurring that blade 103 damages, pencil breaks core and knife rest the problems such as damaging.

In the knife rest of above-mentioned pencil-knife, briquetting 102 and the gap size of blade mounting surface 111 are preset value, to prevent briquetting Gap between 102 and mounting surface is excessive and can not realize that the end by blade 103 is compacted to and be close to blade mounting surface 111.

Preferably, in above-mentioned knife rest, preset value is set as the thickness of blade 103.

In order to facilitate the manufacturing, in above-mentioned knife rest, briquetting 102 is set as being an integral structure with frame body 101.Certainly pressure Block 102 may also be configured to 101 split of frame body, and briquetting 102 modes such as is connected by fixing piece, is bonded and being fixed on frame body 101, the present embodiment is not specifically limited.

In above-mentioned knife rest, briquetting 102 is set as at least two, wherein, the first end of the first briquetting 102 and blade 103 It is corresponding that (i.e. the first briquetting 102 is used to hold out against the first end of blade 103 and the first end of blade 103 is made to be adjacent to blade mounting surface 111), corresponding with the second end of blade 103 (i.e. the second briquetting 102 is used to hold out against the second end of blade 103 simultaneously to the second briquetting 102 The second end of blade 103 is made to be adjacent to blade mounting surface 111).

The utility model embodiment also provides a kind of pencil-knife, including knife rest and the blade 103 for being installed on knife rest, In, knife rest is the knife rest that above-described embodiment provides.
