Abstract
The utility model discloses a quadrangular spline chisel head. The quadrangular spline chisel head comprises a tool bit body (1) and a joint (2), wherein the cross section of the tool bit body (1) is rectangular; one end of the tool bit body (1) is connected with the joint (2); a semicircular first blade (3.1) is arranged at the end part of the other end of the tool bit body (1); second blades (3.2) are respectively arranged on the upper side surface and the lower side surface of the tool bit body (1); the first blade (3.1) and the second blades (3.2) are single-side blades and are perpendicular to each other; an included angel of 30-40 degrees is formed between the blade surface of the first blade (3.1) and the rear surface of the tool bit body (1); a quadrangular spline inserting hole (4) for being inserted with a cutter body of a chisel is formed in the joint (2), and is formed by four semi-circular arcs with the same radius arranged in a tangent manner. According to the utility model, the chisel head is firmer, high in utilization ratio and high in efficiency during processing irregularly shaped products.
Description
Technical field
The utility model relates to cutter, specifically is a kind of interior four corner piece type chisel heads.
Background technology
Chisel is the instrument that the craftsman master worker adopts when being used for chiseling and carving materials such as various wooden, stone matter, beautiful matter, but present chisel is to be fixed together by chisel head and handle, because the handle of chisel damages easily, in case handle damages, whole chisel is scrapped being used with regard to being difficult to, the utilization rate of chisel head is low, can cause the great wasting of resources like this.Be exactly that chisel cutter head of the prior art is generally square spigot in addition, some need processing several times when irregularly shaped in processing, and working (machining) efficiency is low.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of firmer, utilization rate is high and the higher interior four corner piece type chisel heads of efficient during the irregular product of machining shape.
The technical solution of the utility model is: four corner piece type chisel heads in a kind of, and it comprises cutter head body and joint; The cross section of described cutter head body is rectangle; Described cutter head body one end is connected with joint, other end end is provided with first blade of semicircular in shape, the side up and down of described cutter head body is equipped with second blade, described first blade is single face blade and vertical with second blade, the angle at the sword face of first blade and the cutter head body back side is 30～40 degree, be provided with the jack of pegging graft for the chisel blade in the described joint, described jack is four corner piece type holes; Described four corner piece type holes constitute by the equal semi arch of four radiuses is tangent.
After adopting above structure, the utlity model has following advantage: because the joint area of four corner piece type chisel heads is provided with jack in being somebody's turn to do, the tangent four corner piece type holes that constitute of semi arch that the shape of jack is equated by four radiuses, handle can be plugged in the four corner piece type holes like this; If handle damages, can be convenient for changing handle, the utilization rate height of cutter head, and can change different cutter heads.Described cutter head body one end is connected with joint, other end end is provided with first blade of semicircular in shape, the side up and down of described cutter head body is equipped with second blade, described first blade is single face blade and vertical with second blade, like this front can processing plane or the bottom surface be the groove on plane, one-shot forming, easy to process, efficient is higher during the irregular product of utilization rate height and machining shape.
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.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is implemented to be further described.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, interior four corner piece type chisel heads of the present utility model, it comprises cutter head body 1 and joint 2; It is characterized in that: the cross section of described cutter head body 1 is rectangle; Described cutter head body 1 one ends are connected with joint 2, other end end is provided with first blade 3.1 of semicircular in shape, the side up and down of described cutter head body 1 is equipped with second blade 3.2, described first blade 3.1 is single face blade and vertical with second blade 3.2, the angle at the sword face of first blade 3.1 and cutter head body 1 back side is 30～40 degree, be provided with the jack 4 of pegging graft for the chisel blade in the described joint 2, described jack 4 is four corner piece type holes; Described four corner piece type holes constitute by the equal semi arch of four radiuses is tangent.
Described cutter head body 1 and joint 2 are formed in one.
The degree of depth of described jack 4 is between 5cm～10cm.
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in the utility model protection domain.
