The specific embodiment

Combine embodiment, accompanying drawing that the present invention is further described at present:

Present embodiment comprises 2 guide rails, 2 guide rail fixed blocks, slide block 6, knife rest bar 12, connecting rod 13, folder cutter groove 4 and cutter holders 3; Wherein drive disk assembly and kinematic system are included in slide block inside; Can't see inner mechanical device from the outside, meet the succinct requirement attractive in appearance of home-use kitchen tools.The global design outward appearance is: slide block slidably reciprocates on two parallel guide rails, and wherein one is smooth guide rail 9, and another root is the band tooth guide rail 7 of band saw dentation groove; The two ends of two guide rails are separately fixed on right-hand member guide rail holder 8 and the left end guide rail holder 14; Wherein smooth guide rail is used the holding screw fixation; Band tooth guide rail can be around its axis direction rotation; Thereby the tooth of ratchet on can getaway is free to slide, and the adjusting rod of stirring band tooth guide rail right-hand member can be controlled the interlock of tooth and ratchet or separate; Right-hand member guide rail holder 8 and left end guide rail holder 14 are separately fixed at the right ends of common chopping board, and the steel plate of " L " shape is all arranged in their back; The horizontal segment of steel plate be clipped in chopping board below; The groove that vertical section has strip can change the height of steel plate and tighten with the hand nutting; The distance that changes right-hand member guide rail holder 8 and left end guide rail holder 14 goes for the chopping board of different in width, and the distance of right-hand member guide rail holder 8 and left end guide rail holder 14 bottom surfaces and " L " shape steel plate horizontal segment goes for the chopping board of different-thickness.

Knife rest bar 12 is connected on the slide block with connecting rod 13 1 ends; The other end connects to form parallelogram formula quadric chain with folder cutter groove; Hinged with pin between them, the pin axis is parallel with the axis direction of guide rail, and promptly the knife rest bar is determined by slide block with the transverse movement of folder cutter groove; Because will make slide block drive that all parts are moved to the left on it through transmission system when lifting kitchen knife,, under the knife rest bar, designed a stage clip and reached labour-saving purpose when kitchen knife is lifted so need overcome certain resistance when kitchen knife lifts; In the middle of the folder cutter groove is cutter holder; The effect of cutter holder is to clamp kitchen knife; Double roller is housed on the cutter holder, can in the elongated slot of folder cutter groove, rolls moving freely before and after promptly kitchen knife also can be realized when cutting the dish up and down; Such design is the custom that moves forward and backward kitchen knife when people cut the dish in order to meet, and kitchen knife is cut better.Because the rolling of roller in elongated slot do not receive any restriction, thus knife rest and kitchen knife move forward and backward be fully by the user cut the dish the custom determine.Clip to move each other between back kitchen knife and cutter holder and be equivalent to an integral body; Kitchen knife and cutter holder are made the double roller of as a whole usefulness and are fixed in the elongated slot that presss from both sides the cutter groove; Double roller can slide front and back in elongated slot, but transverse movement also promptly can only be followed the slide block move left and right by the restriction of folder cutter groove.Common kitchen knife is fixed on the cutter holder in the folder cutter groove; Folder cutter groove and knife rest bar adopt parallelogram connection-rod hinged; Obtain the reciprocally swinging of knife rest bar through moving up and down of kitchen knife; The knife rest bar be fixed on can the slide block of move left and right on, slide block can be on long guideway move left and right, be carved with a gang saw dentation groove on the anterior guide rail.The non-self-locking screw rod that the swing of knife rest bar drives on it moves up and down, and moving up and down of screw rod will drive the nut rotation, the fork that is being connected on the nut, and the other end and the ratchet of fork are hinged, and the swing of fork will drive ratchet move left and right on band tooth guide rail.Ratchet can streak on the hypotenuse of tooth when the knife rest bar moved downward, but return will be stuck on the straight flange of sawtooth, and anti-sliding piece is moved to the left, and had realized that slide block is unidirectional intermittently of knife rest bar to move.Cover on the sawtooth in the ratchet moving range with an outer cover simultaneously, and together move with slide block, the right-angled trapezium thin plastic sheet that this outer cover is 10 π mm by a right angle waist length is rolled into, and rotating outer cover is covered sawtooth amount in the scalable ratchet moving range.Thereby will can not be stuck in the amount of feeding that does not influence slide block on the sawtooth sliding on the outer cover at the part ratchet that covers in, can guarantee like this no matter what but the sawtooth length of its useful amount of exercise for not hidden by outer cover in its range of movement ratchet move.So can change the amount of feeding that the scope that hides is regulated kitchen knife through rotating outer cover; The effect of outer cover simultaneously also has: make the amount of feeding of oscillating quantity and slide block of knife rest bar irrelevant; Because no matter how many oscillating quantity of knife rest bar in its designed range be; To guarantee that all ratchet can move in the largest motion scope of its design, so the amount of feeding of slide block is promptly artificially controlled by the user by the outer cover decision fully.

During use guide rail is fixed on the common chopping board, again with being clamped on the knife rest of common kitchen knife level, the kitchen knife that can move up and down by the usual action of cutting the dish will equally spacedly intermittently move left when kitchen knife moves up and down, and cuts out the uniform dish of width.If want to change the width of cutting the dish, the adjusting thumb wheel on rotary slider top can be selected the width wanted, and alternative scope is 1mm-20mm.Kitchen knife can only unidirectionally left move; Promptly cut the dish from right to left, this also meets most of people's custom, when switching to high order end; Be rotated down 90 ° to the toothed one side of band tooth guide rail; Can realize separating of ratchet and tooth, push back right-hand member to kitchen knife and will be with the tooth guide rail to go back to again, make ratchet and tooth interlock just can continue to have cut the dish.
