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 shell; Being provided with in the shell can be along the magnetic knife rest of outer cover length direction slip, and the positive front portion of magnetic knife rest forms the suction cutter groove that is used to place blade, and the head of said shell is provided with the opening that supplies blade flexible; It is characterized in that: said magnetic knife rest be provided with one have the trend of popping up push button; The upper edge of said shell is provided with the groove that pushes away along the setting of outer cover length direction, is provided with the some groups of gear grooves that can supply push button location on the both sides inwall of groove pushing away, and the both sides of said push button are provided with this gear groove and cooperate the card base that positions; Said push button is located at through the magnetic knife rest and is pushed away in the groove; And drive the magnetic knife rest and slide along pushing away groove, the card base through both sides cooperates with said gear groove and positions simultaneously, thus the flexible gear that reaches of realizing blade is located.

As improvement; Said shell is to be involuted by protecgulum and bonnet; The inboard of said protecgulum and bonnet forms the guide rail that can supply the magnetic knife rest to embed and slide, and the both sides of said magnetic knife rest are provided with the convexity that embeds guide rail, above the rear portion of magnetic knife rest, offers one and can supply the slot of push button plant; Bottom support at slot and push button has a spring, the trend that push button is had pop up all the time.

As improvement; The top of said blade is provided with bayonet socket; The back side of said magnetic knife rest is provided with the lock dog movable up and down of corresponding locking with blade bayonet socket position; The upper end of said lock dog is provided with the flange with bayonet fittings, and the lower end of lock dog is provided with the right angle flange of outside turnover, between right angle flange and magnetic knife rest, is provided with a back-moving spring; Make lock dog have the trend that moves downward all the time with the blade bayonet locking, the position of stretching out lock dog under the state of putting in place fully corresponding to blade in the front portion of protecgulum be provided with one be used to open lock dog the tool changing switch.

As improvement; The front portion of said protecgulum offers an installing hole, and said tool changing switch can be connected in the installing hole up and downly, and the both sides of tool changing switch are provided with the elasticity card base that offsets with the installing hole inboard; The bottom of tool changing switch is provided with the flanging of inside turnover; The top edge of this flanging just in time offsets with the lower limb of the right angle flange of said lock dog, between the top of flanging and installing hole, is supported with switch spring, makes the tool changing switch have the trend that moves downward all the time; When the tool changing switch moved upward, said flanging drove on the lock dog and transfers from one place to another under escort the locking except that the lock dog blade.

Improve again; Form the opening consistent on the said bonnet with blade shapes; And hinged fastening has one to be equipped with the cutter lid on the bonnet of the outside of opening, said be equipped with cutter lid and bonnet fasten the back form supply that blade stores be equipped with the cutter groove, and be provided with the flexure strip that offsets with blade, magnetic knife rest in the inboard that is equipped with the cutter lid.

Improve again, the outside of said bonnet be provided be equipped with that the cutter lid cooperates can about movable switch, an end and bonnet that said cutter fully covers are hinged, the other end is fixed with the snapping that cooperates of switch through catching groove.

Further improve, the said outside that is equipped with the cutter lid be provided with one can be used for clamping clip.

At last, the inboard two ends of said protecgulum are provided with some joint pins, and said bonnet is provided with corresponding connection counterbore, and said protecgulum is connected fixing with bonnet through screw.

Compared with prior art, the advantage of the utility model is: easy to use, only need press and promote forward push button can drive the magnetic knife rest to front slide; Be pull-in on blade on the magnetic knife rest simultaneously also along with shell is stretched out in slip; Movable during when push button to the gear groove, can position by the needs of blade collapsing length when using, when needing to change blade; Then press and promote forward push button until the end that pushes away groove; Need not shell is taken apart,, just can blade be unloaded fast as long as upwards promote the tool changing switch.The utility model is simple in structure, easy to assembly, not only has fully the cutter function, can change blade fast, and can carry out the gear location by the needs of blade collapsing length when using.
