Abstract
The utility model discloses a chisel head with an internal triangular pattern hole, which comprises a chisel body (1), wherein an edge face (1.1) is arranged on one side of the head of the chisel body (1); an edge opening for machining is formed at the front end of the edge face (1.1); a joint (2) is arranged at the tail of the chisel body (1); the joint (2) and the chisel body (1) are formed integrally; the joint (2) is axially provided with a plughole (2.1) matched with a chisel handle in an inserting connection manner; the plughole (2.1) is the internal triangular pattern hole; the edge face (1.1) is formed by connecting a right-angle half edge face (1.1.1) and an R arc half edge face (1.1.2); and one side of a right-angle side of the right-angle half edge face (1.1.1) is connected with the R arc half edge face (1.1.2). The chisel head is convenient to replace and convenient to carry, and saves time and labor.
Description
Technical field
The utility model relates to the engraving tool technical field, specifically is a kind of chisel head with interior bougainvillea type hole.
Background technology
Chisel, a kind of hand tools that people use always when being engraving.Present chisel generally comprises chisel head and the handle that is connected, and mostly the chisel head is to be fixed on the handle, thereby one can only be the chisel head a kind of specification.In order to satisfy the needs of different occasions, the carpenter has to prepare many chisel, carry and use all very inconvenient.And because chisel head and handle are non-dismountable, and handle damages easily, in case handle damages, whole chisel has been scrapped with regard to whole, very wastes.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of and changes conveniently, the chisel head in bougainvillea type hole in the band time saving and energy saving, easy to carry.
For solving the problems of the technologies described above, the chisel head in bougainvillea type hole in the band that the utility model provides, comprise blade, the monolateral sword face that is provided with of the head of described blade, the front end of described sword face is provided with the cutting edge for processing, the afterbody of described blade is provided with joint, and described joint and described blade are one-body molded; Described joint is provided with the jack that cooperates for the grafting of chisel handle vertically, and described jack is interior bougainvillea type hole; Described sword face is formed by connecting by band right angle half sword face and R circular arc half sword face; Right-angle side one side of described band right angle half sword face is connected with R circular arc half sword face.
After adopting above structure, the utility model compared with prior art has the following advantages:
Because the afterbody of the blade of the chisel head in bougainvillea type hole is provided with the joint in bougainvillea type hole in the band in the band of the present utility model, joint and blade are one-body molded; Can realize removable connection the between cutter head and the chisel handle, and can quickly and easily cutter head and handle be carried out circumferentially spacingly by interior bougainvillea type hole, prevent that the chisel head from rotating to deviate from from handle.When handle of a knife is damaged or changes the chisel head according to need of work, fast changeable.The many usefulness of one cutter, easy accessibility, and also volume is little, in light weight, carries very convenient when especially going out operation.In addition, described sword face is formed by connecting by band right angle half sword face and R circular arc half sword face, has enlarged the scope of application of chisel.
As a kind of improvement of the present utility model, the dual-side of described blade is equipped with the side edge face; The side of described side edge face is the side edge mouth.After adopting this kind structure, but the also operation of described side edge face enlarges the scope of application of chisel more.
As another kind of improvement the of the present utility model, the degree of depth of described jack is 3 ~ 5mm.After adopting this kind structure, can be well cutter head and handle be carried out circumferentially spacing, prevent that cutter head from rotating to deviate from from handle.
Also have a kind of improvement as of the present utility model, described joint is cylindrical.After adopting this kind structure, the cylinder-shaped joint surface is more smooth, and the user can not hurt hand when changing cutter head.
