The specific embodiment

Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:

The 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 from the outside inner mechanical device, meet the succinct requirement attractive in appearance of home-use kitchen tools.Global design outward appearance is: slide block slidably reciprocates on two parallel guide rails, and wherein one is smooth guide 9, and another root is the band tooth guide rail 7 with zigzag groove; The two ends of two guide rails are separately fixed on right-hand member guide rail holder 8 and left end guide rail holder 14, wherein smooth guide 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, stirs with the adjusting rod of tooth guide rail right-hand member and can control the interlock of tooth and ratchet or separated; Right-hand member guide rail holder 8 and left end guide rail holder 14 are separately fixed at the two ends, left and right of common chopping board, have the steel plate of " L " shape after them; 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 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 and connecting rod 13 one end are connected on slide block, the other end connects to form parallelogram-type quadric chain with folder cutter groove, hinged with pin between them, pin axis is parallel with the axis direction of guide rail, and knife rest bar is determined by slide block with the transverse movement of folder cutter groove; Because will make slide block drive all parts on it to be moved to the left by transmission system while lifting kitchen knife, so need to overcome certain resistance when kitchen knife lifts, under knife rest bar, designed a stage clip and reached labour-saving object when kitchen knife is lifted; In the middle of folder cutter groove, it is cutter holder, the effect of cutter holder is to clamp kitchen knife, Double-row-roller is housed on cutter holder, can in the elongated slot of folder cutter groove, roll, be moving freely before and after 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 can make kitchen knife cut better.Because the rolling of roller in elongated slot is not subject to any restriction, so moving forward and backward of knife rest and kitchen knife is to be accustomed to determining by cutting the dish of user completely.Clip between rear kitchen knife and cutter holder and mutually can not move and be equivalent to an integral body, kitchen knife and cutter holder are done in the as a whole elongated slot that is fixed on folder cutter groove with Double-row-roller, Double-row-roller slides before and after can be in elongated slot, but transverse movement limits by pressing from both sides cutter groove, also can only follow slide block and move left and right.Common kitchen knife is fixed on the cutter holder in folder cutter groove, folder cutter groove and knife rest bar adopt parallelogram connection-rod hinged, by moving up and down of kitchen knife, obtain the reciprocally swinging of knife rest bar, knife rest bar is fixed on the slide block that can move left and right, slide block can move left and right on long guideway, on anterior guide rail, is carved with row's saw-tooth grooves.The swing of knife rest bar drives the non-self-locking screw rod on it to move up and down, the moving up and down drive nut rotation of screw rod, and the fork that is being connected on nut, the other end and the ratchet of fork are hinged, and the swing of fork moves left and right drive ratchet on band tooth guide rail.When knife rest bar moves downward, ratchet can streak on the hypotenuse of tooth, but return will be stuck on the straight flange of sawtooth, and anti-sliding piece is moved to the left, and having realized slide block is the unidirectional intermittent movement of knife rest bar.With an outer cover, cover on the sawtooth in ratchet moving range 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 adjustable ratchet moving range.Thereby at the part ratchet covering in, will be on outer cover slide and can not be stuck in the amount of feeding that does not affect slide block on sawtooth, can guarantee like this no matter ratchet moves the how many but sawtooth length of its useful amount of exercise for not hidden by outer cover in its range of movement.So can change the amount of feeding that the scope hiding regulates kitchen knife by rotating outer cover, the effect of outer cover simultaneously also has: make the oscillating quantity of knife rest bar and the amount of feeding of slide block irrelevant, because no matter the oscillating quantity of knife rest bar in the scope of its design is how many, all by guaranteeing that ratchet can move within the scope of the largest motion of its design, therefore the amount of feeding of slide block is determined by user's manual control by outer cover completely.

During use, guide rail is fixed on common chopping board, then by being clamped on 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 spaced intermittent movement left when kitchen knife moves up and down, and cuts out the uniform dish of width.If want, change the width of cutting the dish, the adjusting thumb wheel on rotary slider top can be selected the width of wanting, and alternative scope is 1mm-20mm.Kitchen knife is single-way moving left, cut the dish from right to left, this also meets the custom of most people, when switching to high order end, band toothed one side of tooth guide rail is rotated down to 90 °, can realize the separated of ratchet and tooth, kitchen knife be pushed back to right-hand member and again band tooth guide rail is gone back to, make ratchet and tooth interlock just can continue to have cut the dish.
