Abstract
A chisel head with a right-angle internal quadrangle comprises a chisel body (1), a chisel edge (2) and a joint (3), wherein the cross section of the chisel body (1) is trapezoidal; one end of the chisel body (1) is connected with the joint (3); the chisel edge (2) is arranged at the other end of the chisel body (1); the chisel edge (2) is symmetrical along a width bisector of the chisel body (1); an edge face (2.1) of the chisel edge (2) is V-shaped; an included angle a between the edge face (2.1) and a horizontal plane is 45 DEG; and a plughole (4) for splicing a handle with the chisel head is formed in the joint (3) and is an internal quadrilateral hole (4.1). Since the handle can be spliced in the quadrilateral hole, if the handle is damaged, the handle can be replaced conveniently; the utilization ratio of the set chisel head is high; when the processed cross section has a certain included angle, the once forming can be achieved; and the processing is more time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of cutter, particularly relates to tetragonal chisel head in the band right angle.
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, causes the great wasting of resources; Secondly, because cutter head is flat cutter head, under specific situation during the different cross section of processing, can't the time processing moulding, can only process several times with chisel, and the shape that processes can't meet the demands, also increased process time simultaneously, waste time and energy.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of firmer, utilization rate is high and tetragonal chisel head in the band right angle of the higher and replaceable handle of efficient during the irregular product of machining shape.
The technical solution of the utility model is: tetragonal chisel head in a kind of band right angle, and it comprises blade, blade and joint, the cross section of described blade is trapezoidal; One end of described blade is connected with joint; Described blade is located on the other end of blade; Described blade is along blade width bisector symmetry; The sword face of described blade is V-shaped; The angle a of described sword face and horizontal plane is 45 degree; Described joint is provided with the jack for handle and the grafting of chisel head; Described jack is interior tetragonal hole.
The utlity model has following advantage as can be seen according to such scheme: because the joint of tetragonal chisel head is provided with jack in this band right angle, handle just can be plugged in the hole like this, if damaging appears in handle, also can be convenient for changing handle, and when the processing cross section is in a certain angle, namely can one-shot forming process, make processing more time saving and energy saving.
As preferably, described blade and joint are formed in one, and such chisel header structure can be very firm, and is not fragile.
As preferably, the degree of depth of described jack is 2cm～6cm, 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 enforcement of the present utility model is further described.
Tetragonal chisel head in a kind of band right angle, it comprises blade 1, blade 2 and joint 3, it is characterized in that: the cross section of described blade 1 is trapezoidal; One end of described blade 1 is connected with joint 3; Described blade 2 is located on the other end of blade 1; Described blade 2 is along blade 1 width bisector symmetry; The sword face 2.1 of described blade 2 is V-shaped; Described sword face 2.1 is 45 degree with the angle a of horizontal plane; Described joint 3 is provided with the jack 4 for handle and the grafting of chisel head; Described jack 4 is interior tetragonal hole 4.1.
Described blade 1 and joint 3 are formed in one.
The degree of depth of described jack 4 is 2cm～6cm.
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.
Claims (3)
