Description

A kind of cutter

Technical field

The utility model relates to a kind of technical field of cutter.

Background technology

Cutter is a kind of common hand tools, is commonly used to cut paper, leather, plastic sheet or hardboard etc.Existing cutter kind is a lot; Convenient in order to change blade, a lot of cutters that occur on the market have the function that can load and unload blade, are 200920117976.1 Chinese patent " but cutter of a kind of automatic tool changer sheet " like the patent No.; Comprise shell and blade; Be provided with the magnetic push broach piece that can slide along the length direction of shell in the shell, be provided with vertical and the suitable blade storeroom of shape blade in the shell, magnetic push broach piece constitutes the bottom surface of blade storeroom; The head of shell is provided with out the edge of a knife; Magnetic push broach piece has upwardly extending push button, and the upper edge of shell is provided with the groove that pushes away along the outer cover length direction, and push button stretches into and pushes away in the groove, and the front end that pushes away groove has a horizontal groove that turns, and the bearing of trend that turns groove deviates from the blade storeroom.During use blade is pull-in on the magnetic push broach piece, magnetic push broach piece is pushed away forward through promoting push button, thus also drive simultaneously adhesive again the blade on the magnetic push broach piece push away forward blade released out the edge of a knife.When push button be pushed into groove foremost the time, push button pulled turns in the groove, then magnetic push broach piece produces rotation to a certain degree, thereby can blade be taken off.This structure more complicated; Also be provided with torsion spring between magnetic push broach piece and the rotating shaft, the torsion spring time has been grown yielding, thereby reduces the service life of cutter; And there is not a shift function; Can not position by the needs of blade collapsing length when using, and assembling is also cumbersome, also needs further to improve.

Summary of the invention

The utility model technical problem to be solved is to the above-mentioned state of the art and a kind of cutter simple in structure, easy to assembly is provided, and can carry out the gear location by the needs of blade collapsing length when using.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of cutter; Comprise that one has the housing of medium altitude chamber, have bar hole on the sidewall of housing one side, a knife rest places in the room of housing slidably; Knife rest is provided with can be with the blade of knife rest synchronization telescope; It is characterized in that: the front end of said housing have one can supply knife rest to stretch out opening, be provided with a push button in the said bar hole slidably, the inner end of this push button and knife rest elasticity are joined; And can drive the knife rest slip; Two middle side parts up and down of push button are provided with and the inboard of the bar hole card base that offsets of edges at two ends up and down, and the inwall of both sides up and down of said bar hole is provided with some groups and can supplies the card base of push button to embed the gear groove that positions, be provided with in the position parallel, the front portion of knife rest with push button one be used to change blade the tool changing switch.

As improvement; Said knife rest is to be involuted by tool rest bracket and knife rest loam cake, and wherein the inboard of tool rest bracket is provided with the suction cutter groove of magnetic, and the cutter head of said blade stretches out outside the knife rest; Blade is adsorbed in the suction cutter groove of tool rest bracket, and locks through being located at the tool changing switch that covers on the knife rest.

As improvement; The rear portion of said knife rest loam cake offer one can supply push button to place slot; The inboard of said tool rest bracket is provided with corresponding socket; The slot that the knife rest loam cake is passed in the inner end of said push button is plugged on the socket of tool rest bracket, and between socket and push button, is supported with a spring, the trend that the edges at two ends that makes push button have outside all the time ejection and bar hole offsets.

Improve again; The top of said blade is provided with bayonet socket; Said knife rest loam cake offers an installing hole corresponding to the position of blade bayonet socket, and said tool changing switch can be limited in the installing hole up and downly, fixes through being located at the inboard pad of knife rest loam cake; Be provided with flange with the blade bayonet fittings in the upper end of tool changing switch; Be supported with a back-moving spring above the flange and between the knife rest inwall, making the tool changing switch have the trend that moves downward all the time with the blade bayonet locking, the bottom of said tool changing switch is provided with the flange that hand is dialled of being convenient to of outside turnover.

Improve, the gear groove of said bar hole both sides is three groups, is located at the two ends and the centre position of bar hole respectively again.

Further improve; The front portion of said tool rest bracket up and down both sides form one

the type groove; The both sides up and down of said knife rest loam cake form

the type projection that cooperates with it; After said tool rest bracket and knife rest loam cake are involutory, connect fixing through screw.

Further improve, said housing is to be involuted by base and loam cake, and the outside of said base also is compounded with plastic bottom flap and base protection sleeve, and the outside of said loam cake is compounded with upper plastic cover cover plate and loam cake sheath.

At last, be socketed with the transparent broach shell that is used to protect on the cutter head of said blade.

Compared with prior art, the advantage of the utility model is: need not to form guide rail, guide groove in the housing, only need during assembling the knife rest housing of packing into is got final product, simplified the mould structure of housing like this, make process and assemble all very convenient; The push button that slides through of knife rest positions, and is very easy to use, when needing to change blade, need not shell is taken apart, as long as upwards promote the tool changing switch, just can blade be unloaded fast.The utility model is simple in structure, easy to assembly, not only can change blade fast, and can carry out the gear location by the needs of blade collapsing length when using.
