Abstract
The utility model discloses a multifunctional cutter bit for a hardware screw driver. The multifunctional cutter bit comprises a head portion, a step portion and a cutter tail portion, wherein the cutter tail portion and the step portion are coaxially arranged with the head portion, and the outer diameter of the step portion is larger than that of the cutter tail portion and the head portion. The head portion comprises a cutting edge and a columnar part, wherein the cutting edge is used for a clamping opening of a screw cap to insert, and the columnar part is used for connecting the cutting edge and the step portion. The columnar part and the cutter tail portion are both regular polygon prisms, and the tail portion of the cutter bit can be arranged in a through hole in a rotating disc. Moreover, in the using process, the ejecting rod is utilized to push the cutter bit in a blocking portion in an assembly hole, and the blocking portion abuts against an assembly hole, and therefore the multifunctional cutter bit is normally used.
Description
Technical field
The utility model relates to a kind of cutter head, refers to especially a kind of multi-functional five metals screwdriver cutter head.
Background technology
The five metals chasing tool is a kind of hardware ﹠ tools commonly used, the patent No. is in the utility model of ZL200620064061-5, a kind of Multi-functional hardware has been described, this screwdriver comprises handle, rotating disk and working head, dial rotation is installed in the front end of handle, working head is fixed in the fixing hole on the rotating disk, rotating disk then fixedly on the handle, although the chasing tool of this structure can concentrate in together several working heads and chasing tool, has been save the tool box by alignment pin, but this structure is very loaded down with trivial details when selecting working head, need to unclamp alignment pin, then rotary turnplate is selected suitable working head, then alignment pin is being installed, like this, repeatedly relax alignment pin, cause easily the alignment pin aperture to become large, and whole work is to the support holding capacity that relies on alignment pin, alignment pin is very easy to damage so, and impact is used.In addition, because rotating disk is installed in the handle front end, the volume of handle front end just seems larger so, at all can't be in deep hole demounting bolt, thereby the scope of application of having limited to this hardware ﹠ tools.And for solving the problems of the technologies described above, a kind of like this five metals chasing tool has appearred, this chasing tool comprises handle, securement head and the working beam that is arranged on the securement head, described securement head is provided with installation cavity, be rotatablely equipped with the rotating disk of column in the described installation cavity, described securement head is provided with the knob of rotary turnplate, the cylinder of described rotating disk is provided with at least two through holes that run through the turntable rotation center, one end of each through hole is fitted with cutter head, described working beam is provided with is convenient to the pilot hole that cutter head passes through, the end of pilot hole is provided with stopper, described handle is provided with the slide opening coaxial with pilot hole, described through hole can be with pilot hole, slide opening is communicated with, be slidingly fitted with in this slide opening and pass through hole and head on the push rod of cutter head to the pilot hole, described handle is provided with axial slide, is provided with the push button that connects push rod in the chute, and the described leading portion of holding chute is provided with the arc-shaped slot that holds push button.Obviously, the working head that the chasing tool of this structure can't be suitable on the market all is column structure cutter heads of same external diameter, therefore, is necessary to provide a kind of cutter head of new structure.
The utility model content
Technical problem to be solved in the utility model is: a kind of multi-functional five metals screwdriver cutter head is provided, the afterbody of this cutter head can be installed in the through hole of rotating disk, and utilizes in use push rod to promote cutter head to enter stopper and normal use that leans pilot hole in the pilot hole.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of multi-functional five metals screwdriver cutter head comprises head, stage portion and cutter afterbody, described cutter afterbody, stage portion and the coaxial setting of head; The external diameter of described stage portion is greater than the external diameter of cutter afterbody, head, and described head comprises that this column position and cutter afterbody are positive polygon prism for the stylolitic part of the cutting edge that inserts the cap nut upper latch notch and connection cutting edge and stage portion.
As a kind of preferred scheme, the breech face of the rear end face of described stage portion, cutting edge and cutter afterbody is equipped with the magnetic position.
As a kind of preferred scheme, described column position and cutter afterbody are positive six prisms, and outside dimension equates.
After having adopted technique scheme, effect of the present utility model is: since this cutter head comprise head,, stage portion and cutter afterbody, described cutter afterbody, stage portion and the coaxial setting of head; The external diameter of described stage portion is greater than the external diameter of cutter afterbody, head, described head comprises the stylolitic part for the cutting edge that inserts the cap nut upper latch notch and connection cutting edge and stage portion, this column position and cutter afterbody are positive polygon prism, therefore, when not using, the cutter afterbody of cutter head is inserted in the through hole of rotating disk, stage portion is adjacent to the edge, hole of through hole, and when need using, promote push rod, push rod heads on cutter head and leaves that through hole enters into pilot hole until the front end face of stage portion withstands on the stopper, then push button is rotated to arc-shaped slot.Push rod and stopper are fixed cutter head like this, and cutter head can use.Like this, the cutter head of this structure has satisfied the use of this special multi-functional five metals screwdriver, has guaranteed that this chasing tool selects cutter head quick, reasonable stress.
Again because the breech face of rear end face, cutting edge and the cutter afterbody of described stage portion is equipped with the magnetic position, therefore, when off position, the cutter afterbody of cutter head is by magnetic force and push rod absorption, and be pulled in the through hole by push rod, and when the cutter afterbody of cutter head enters in the through hole, the magnetic force of stage portion again with the hole of cutter head and through hole along absorption, thereby can rotate effectively reliably with rotating disk.
