Abstract
The utility model provides a single-sided arc right-angled heptagonal spline chisel bit. The chisel bit comprises a tool bit main body and a joint, wherein one end of the tool bit main body is connected with the joint, and a first blade is arranged at the end part of the other end; second blades are arranged on the upper side surface and the lower side surface of the tool bit main body; the first blade and the second blades are single-sided blades; the joint between the second blade on the upper side of the tool bit main body and the first blade is set to be a single-sided arc-shaped blade; the joint between the second blade on the lower side of the tool bit main body and the first blade is set to be a single-sided right-angled blade; an insertion hole used for being in plug-in connection with the tool shank of a chisel is formed in the joint; the insertion hole is a heptagonal spline hole. The chisel bit can directly process and shape the specific cross section with less time and effort, and the chisel shaft can be replaced.
Description
Technical field
The utility model relates to cutter, specifically is heptangle flower type chisel head in a kind of pedion circular arc band right angle.
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, handle of a knife, and cutter head, the cross section of handle of a knife 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: provide a kind of for heptangle flower type chisel head in the pedion circular arc band right angle of the directly machine-shaping of specific cross section, saving of work and time, replaceable chisel handle.
The technical solution of the utility model is: the utility model provides heptangle flower type chisel head in a kind of pedion circular arc band right angle, and it comprises cutter head body and joint; Described cutter head body one end is connected with joint, other end end is provided with first blade, the side up and down of described cutter head body is equipped with second blade, described first blade and second blade are the single face blade, second blade of the upside of described cutter head body and the junction of first blade are set to the single face curved blade, second blade of the downside of described cutter head body and the junction of first blade are set to single face right angle blade, be provided with the jack of pegging graft for the chisel handle of a knife in the described joint, described jack is heptangle flower type hole.
The shape of cross section in described heptangle flower type hole is connected and composed by the interior concave arc that seven radiuses equate.
After adopting above structure, the utlity model has following advantage: because the joint area of heptangle flower type chisel head is provided with jack in this pedion circular arc band right angle, the heptangle flower type hole that the interior concave arc that the shape of jack is equated by seven radiuses connects and composes, the chisel handle of a knife can plug together fixing by this hole and chisel head like this, and has circumferential attributive function, the chisel head can be separated with the dismounting of chisel handle of a knife, carry out the replacing between the dissimilar chisel heads, saved the space of the instrument of putting, can change the chisel handle of a knife after the chisel handle of a knife damages simultaneously continues to use, save cost, first blade of described cutter head is the single face sword and becomes R circular arc band square, constitute 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.
As preferably, described cutter head body and joint are formed in one, and the chisel header structure is firm like this, and is not fragile.
As preferably, the degree of depth of described jack is between 5cm～10cm, this degree of depth can prevent that the user is excessive because of the axial inertia force of handle of a knife in operating process, and handle of a knife and cutter head are thrown off, and has also guaranteed synchronism and stability when handle of a knife drive cutter head rotates in a circumferential direction simultaneously.
