Abstract
The utility model discloses an inner-quadrangular-hole single-sided arc chisel head with a right angle, which comprises a joint, a chisel body and a chisel head part, wherein an inner quadrangular hole matched with a chisel handle is formed in the joint; the chisel handle can be fixed with the chisel head through the hole in an inserting manner; the joint and the chisel body can be integrally formed, can be connected in a welding manner or connected by threads; single-sided chisel body edges are arranged on the two sides of the chisel body; single-sided chisel head edges are arranged on the chisel head part; a single-sided arc edge is arranged at a connecting part of the chisel body edge on one side of the chisel body and the chisel head edge; and a single-sided right-angle edge is arranged at a connecting part of the chisel body edge on the other side of the chisel body and the chisel head edge. The joint is provided with the inner quadrangular hole, so that the chisel handle can be fixed with the chisel head through the hole in an inserting manner, and has a circumferential limiting function; the chisel head can be dismounted and separated from the corresponding handle; replacement among the chisel heads in different types can be conducted; and a space for putting tools is saved.
Description
Technical field
The utility model relates to a kind of chisel head of pedion circular arc band right angle of interior tetragonal hole.
Background technology
Chisel is a kind of speciality cutter that the craftsman master workers often use when being used for the handicraft of materials such as various wooden, the beautiful matter of sculpture, Shi Zhi.Present chisel generally comprises handle and chisel head, and the afterbody of described chisel head embeds in the handle and fixes, and described chisel head comprises afterbody, blade, and cutter head, the cross section of blade is rectangular, and cutter head comprises blade and the edge of a knife.The chisel of above prior art has the following disadvantages: chisel head and handle are fixing non-dismountable, handle damages and just causes whole chisel to be difficult to use even scrap, because cutter head is generally the plane, can only processing plane, if run into shape such as right angle, the arc angling etc. of processing varying cross-section, then can't the time processing moulding, can only process several times with chisel, increase process time, make that processing is time-consuming, and the shape that processes does not satisfy normal requirement.
The utility model content
Technical problem to be solved in the utility model is to overcome the shortcoming of above prior art: a kind of chisel head for the directly machine-shaping of specific cross section, saving of work and time, replaceable chisel handle is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: the chisel head at the pedion circular arc band right angle in tetragonal hole in a kind of, it comprises joint, blade and cutter head, described joint is provided with an interior tetragonal hole that matches with the chisel handle, the chisel handle can plug together fixing by this hole and chisel head, described joint can one-body moldedly also can be welded to connect or be threaded with blade, described blade both sides are equipped with the blade blade of single face, described cutter head is provided with the cutter head blade of single face, the blade blade of described blade one side and the junction of cutter head blade are set to the single face curved blade, and the blade blade of blade opposite side and the junction of cutter head blade are set to single face right angle blade.
As preferably, described joint and described blade are one-body molded.One-body molded that joint is connected with blade is more firm, and has simplified the manufacture craft of described cutter head.
As preferably, the degree of depth of described jack is between 2cm～5cm.This degree of depth can prevent the user in operating process because of the chisel arbor to inertia force excessive, and chisel handle and cutter head are thrown off, also guaranteed synchronism and stability when the chisel handle drives cutter head and rotates in a circumferential direction simultaneously.
As preferably, described in the hole depth in tetragonal hole be 3cm.
The beneficial effects of the utility model are: after adopting above structure, the utility model is concrete following advantage compared with the prior art: because described joint is provided with tetragonal hole in, the chisel handle can plug together fixing by this hole and chisel head, and has circumferential attributive function, the chisel head can be separated with corresponding handle dismounting, carry out the replacing between the dissimilar chisel heads, saved the space of the instrument of putting, can change handle after the chisel handle damages simultaneously continues to use, save cost, described cutter head blade is the single face sword and becomes R circular arc band square, the described cutter head edge of a knife constitutes by a circular arc with a straight flange, cutter head both can have been processed regular corner and also can process irregular arc corner like this, made the processing saving of work and time.
