Abstract
The utility model discloses a double-sided flat chisel bit with an enneagonal hole, which comprises a connector (2), a chisel body (3) and blades (5), wherein the connector (2) is integrated with the chisel body (3); an insertion hole (1) in plug-in connection with a chisel rod is formed in the connector (2), and is the enneagonal hole matched with the chisel rod; the cross section of the chisel body (3) is rectangular; one end of the chisel body (3) is connected with the connector (2); and the blades (5) are arranged at the other end and on two side walls of the chisel body (3); each blade (5) is formed by intersecting two inclined planes (4) that are both inclined with the plane of the chisel body; and the blade (5) at the end of the chisel body (3) comprises two corner blades that are right-angled blades. After the structure is adopted, all that is needed is to unplug the chisel bit and insert another chisel bit, the chisel body can be replaced, therefore, the operation is convenient; and meanwhile, all that is needed is to carry the chisel body, the chisel bit can be carried, the weight of a handle is reduced, and the carrying is convenient.
Description
Technical field
The utility model relates to the engraving tool technical field, specifically is a kind of flat cutter head of two-sided chisel with interior nonagon hole.
Background technology
Chisel, a kind of hand tools that people use always when being engraving, traditional chisel generally is made up of handle and knife bar, and the end of knife bar is cutter head, usually according to concrete instructions for use and precision, cutter head is divided into single face cutter head for horizontal sliding, be used for the two-sided cutter head of punchinging.Usually, the single face cutter head is used for fine finishining, and it is mainly used in pushing away the plane; And two-sided cutter head is used for roughing, and it can be punchinged fast.But there is following shortcoming in this chisel with two-sided cutter head: because handle and knife bar are fixing non-removable, when need to change different chisels under different operating positions, therefore, people need carry many chisel when engraving, and Heavy Weight is very inconvenient.
The utility model content
Technical problem to be solved in the utility model is, a kind of interchangeable bit is provided, thus the flat cutter head of two-sided chisel in nonagon hole in the band easy to use.
For solving the problems of the technologies described above, the flat cutter head of two-sided chisel in nonagon hole comprises joint, blade and blade in the band that the utility model provides, and joint and blade are one-body molded; Joint is provided with for the jack of pegging graft with the chisel knife bar, the interior nonagon hole of described jack for matching with the chisel knife bar; The cross section of described blade is rectangle, and an end of blade links to each other with joint, and the other end of blade and two sidewalls are blade, and described blade all forms with the inclined-plane of blade plane inclination is crossing by two; The blade of described blade end comprises two corner blades, and these two corner blades are the right angle blade.
The angle on two inclined-planes of described formation blade is 60 °～90 °, and wherein Zui Jia angle is 90 °.
Described have knuckle near the blade on the blade sidewall of joint.
After adopting above structure, the utility model compared with prior art, have the following advantages: because cutter head and being connected of knife bar have been adopted removable grafting, in other words, the chisel knife bar is outer nonagon, and joint is interior nonagon hole, like this, as long as when changing cutter head, pull up cutter head, plug other one cutter head got final product, easy to operate; Simultaneously, it is just passable also only need to carry cutter head when carrying, and has reduced the weight of handle, and it is also convenient to carry.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of the flat cutter head of two-sided chisel in nonagon hole in the utility model band of Fig. 1～shown in Figure 4 as can be known, it comprises joint 2, blade 3 and blade 5, joint 2 is one-body molded with blade 3, joint 2 is provided with for the jack 1 of pegging graft with the chisel knife bar, the interior nonagon hole of described jack 1 for matching with the chisel knife bar.The cross section of described blade 3 is rectangle, and an end of blade 3 links to each other with joint 2, and the other end of blade 3 and two sidewalls are blade 5, and described blade 5 is intersected by two inclined-planes 4 that all tilt with the blade plane and forms.The blade 5 of described blade 3 ends comprises two corner blades, and these two corner blades are the right angle blade.
The angle on two inclined-planes 4 of described formation blade 5 is 60 °～90 °, and in the present embodiment, the angle on two inclined-planes 4 of described formation blade 5 is 90 °.
Described have knuckle 6 near the blade 5 on blade 3 sidewalls at joint 2 places.
