Abstract

The invention discloses a carving knife which comprises a knife handle and a knife head. The knife head is provided with a sharp part, a blunt part and a tip part. The knife head is installed on a connecting base, the connecting base is connected with the knife handle, the sharp part and the blunt part are located on two sides of the knife head respectively and integrally continuously distributed along the two sides, the carving edge of the sharp part is crossed on the tip part with the abrasion edge of the blunt part, and an arc-shaped part is further arranged between the connecting base and the tip part to enable the sharp part and the blunt part to be bent inwards. Any part of the sharp part on one side of the carving knife can be carved, and the abrasion edge of the blunt part on the other side of the carving knife performs edge and corner abrasion conveniently and easily while a landscape tree is carved; the arc-shaped part is arranged between the connecting base and the tip part to enable the sharp part and the blunt part to be bent inwards, the knife head can enter groove corners inside a carved object due to the arrangement of the arc-shaped part, the carving edge of the sharp part is adopted to carve and trim the groove corners, and the abrasion edge of the blunt part is also utilized simultaneously to abrade the internal groove corners.

Description

A kind of graver

Technical field

The present invention relates to engraving equipment technical field, especially relate to and can curve inwardly, to inner and the outside graver that carries out comprehensive engraving.

Background technology

Modern requires increasing to the quality of life, need to carve landscape tree, to meeting its aesthetic standard, but existing graver used, designs unreasonablely, and inconvenient operation, during engraving, generally will be held in the hand graver for a long time; Sharp knife and blunt knife use back and forth simultaneously, and tool changing operation is loaded down with trivial details, and time length is unfavorable for grasping operation.

In Chinese patent literature CN202806129U, disclose a kind of graver, the technical scheme of employing is to comprise cutter head and handle of a knife, the removable connection of described cutter head and handle of a knife; Described cutter head afterbody is provided with Connection Block; Handle of a knife comprises that main handle and secondary handle form, and the front end of main handle is provided with the tensioning mouth extending out, and secondary sleeve is threaded on main handle and with main handle, and the upper end of secondary handle is the contraction mouth of interior receipts, and the tensioning mouth of main handle front end is positioned at the contraction mouth of secondary handle upper end.

The shortcoming of technique scheme is, can not wear and tear to object, and can only carve object surface in engraving, cannot carve inner.

A kind of graver is disclosed again in Chinese patent literature CN203046695U, the technical scheme adopting is to comprise cutter hub, it is characterized in that: described cutter hub one end has cutter head, the other end has handle of a knife, cutter hub mid portion caves inward, sunk part outer wall has antiskid thread, both sides, cutter head one end have respectively the sharp edge of a knife and dull edge, the beneficial effect of its generation is to be rationally provided with and to control screw thread on cutter hub, be convenient to hold operation, cutter head both sides are respectively equipped with sharp knife edges and blunt edges, easy to operate, this technical scheme Shortcomings is that the extension of blunt edges falls short of, can not well to object, wear and tear and cannot carve inner.

Therefore, being necessary to work out a kind of novel graver can carve and can wear and tear to object in engraving inner.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of easy to use, simple and reasonable, the graver of can be simultaneously landscape tree outside and internal access corner being carved and being worn and torn.

For solving the problems of the technologies described above, the technical solution used in the present invention is, this graver comprises handle of a knife and cutter head, described cutter head has sharp portion, blunt portion and tip, described cutter head is contained on Connection Block, described Connection Block is connected with handle of a knife, described sharp portion and blunt portion lay respectively at the both sides of cutter head, the whole continuous distributed along both sides, the engraving edge of sharp portion and the wearing and tearing edge of described blunt portion intersect at tip, also have a curved portions sharp portion and blunt portion are curved inwardly between Connection Block and tip.

Cutter head has sharp portion, blunt portion and tip, sharp portion and blunt portion lay respectively at the both sides of cutter head, along both sides overall distribution, the engraving edge of sharp portion and the wearing and tearing edge of described blunt portion intersect at tip, the beneficial effect of its generation is any position of the graver one sharp portion of side to be carved landscape tree, the wearing and tearing edge, blunt portion of its opposite side, operating personnel can carry out water caltrop wearing and tearing when landscape tree is carved, convenient and simple; Between Connection Block and tip, also having a curved portions curves inwardly sharp portion and blunt portion, owing to being provided with curved portions on cutter head, cutter head can be entered comprise the internal access corner of the engraving object of landscape tree, adopt the Dui Gou corner, engraving edge of sharp portion to carve and repair, also with the wearing and tearing edge of blunt portion, can wear and tear to inner limes marginis angle simultaneously.

Adopt the graver of technique scheme, easy to use, simple and reasonable, can landscape tree outside and internal access corner be carved and be worn and torn simultaneously.

Further improve and be, on described handle of a knife, be provided with groove, in described groove, guide shaft is installed, between described guide shaft one end and described Connection Block, a pair of bevel gear being meshed is installed, adopt such setting, the beneficial effect of its generation is, the propelling movement by guide shaft is mobile cutter head fast, make cutter head be shifted in the internal access corner of engraving object, conversion engraving angle simultaneously.

Further improve and be, be provided with the burr of arranging by rule on described wearing and tearing edge, described burr is continuous distributed thereon, is provided with the roughness that burr has increased wearing and tearing edges at wearing and tearing edge, makes its abrasive effect better.

Further improve and be, tooth pitch between described bevel gear is 2-4mm, tooth pitch is defined as to 2-4mm, the beneficial effect of its generation is, make the movement of cutter head quickly and orderly in narrow and small space, ditch corner, can not be shifted because tooth pitch is excessive too large, can not move because tooth pitch is too little slowly yet, cause operating personnel to grip guide shaft overlong time.

Further improve and be, on described handle of a knife, to have hand protection layer, the beneficial effect of its generation be to be conducive to improve the comfort of operating personnel's hand to cover.
