Description
Technical field
The present invention relates to a kind of cutter head, be meant that especially a kind of multi-functional five metals screwdriver uses cutter head.
Background technology
The five metals chasing tool is a kind of hardware & tools commonly used, and the patent No. is in the invention of ZL200620064061-5, has described a kind of adjustable multifunctional hardware & tools, and this screwdriver comprises handle, rotating disk and working head; Dial rotation is installed in the front end of handle, and working head is fixed in the fixing hole on the rotating disk, and rotating disk is then by alignment pin fixedly on the handle; Though the chasing tool of this structure can concentrate in together several working heads and chasing tool, has save the tool box, this structure is very loaded down with trivial details when selecting working head; Need unclamp alignment pin, rotary turnplate is selected suitable working head then, then at the installing and locating pin; Like this, relax alignment pin repeatedly, cause the alignment pin aperture to become big easily; And whole work is to the support holding capacity that relies on alignment pin, and alignment pin is very easy to damage so, and influence is used.In addition, because rotating disk is installed in the handle front end, the volume of handle front end just seems bigger 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 is arranged at the working beam on the securement head; Said securement head is provided with installation cavity, is rotatablely equipped with the rotating disk of column in the said installation cavity, and said securement head is provided with the knob of rotary turnplate; The cylinder of said rotating disk is provided with at least two through holes that run through the rotating disk pivot; One end of each through hole is fitted with cutter head, and said working beam is provided with is convenient to the pilot hole that cutter head passes through, and the end of pilot hole is provided with retaining portion; Said handle is provided with the slide opening coaxial with pilot hole; Said through hole can be communicated with pilot hole, slide opening, is slidingly fitted with in this slide opening to pass through hole and head on the push rod in cutter head to the pilot hole, and said handle is provided with axial slide; Be provided with the push button that connects push rod in the chute, the said 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.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of multi-functional five metals screwdriver to use cutter head, the afterbody of this cutter head can be installed in the through hole of rotating disk, and utilizes push rod to promote to lean in the cutter head entering pilot hole retaining portion and normal use of pilot hole in use.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of multi-functional five metals screwdriver is used cutter head, comprises head, stage portion and cutter afterbody, said cutter afterbody, stage portion and the coaxial setting of head; The external diameter of said stage portion is greater than the external diameter of cutter afterbody, head, and said head comprises and be used to insert the cutting edge of cap nut upper latch notch and the stylolitic part that connects cutting edge and stage portion that this column position and cutter afterbody are positive polygon prism.
As a kind of preferred scheme, the breech face of the rear end face of said stage portion, cutting edge and cutter afterbody is equipped with the magnetic position.
As a kind of preferred scheme, said column position and cutter afterbody are positive six prisms, and outside dimension equates.
After having adopted technique scheme, effect of the present invention is: since this cutter head comprise head,, stage portion and cutter afterbody, said cutter afterbody, stage portion and the coaxial setting of head; The external diameter of said stage portion is greater than the external diameter of cutter afterbody, head, and said head comprises and be used to insert the cutting edge of cap nut upper latch notch and the stylolitic part that connects cutting edge and stage portion that 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, and 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 through hole and enter into pilot hole and withstand in the retaining portion until the front end face of stage portion, then push button is rotated in the arc-shaped slot.Cutter head is fixed by push rod and retaining portion 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 said stage portion is equipped with the magnetic position; Therefore, when off position, the cutter afterbody of cutter head is through 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.
