The specific embodiment

Embodiment 1

Shown in Fig. 1～4, novel cutting knife described in the utility model has handle of a knife 1, tool rest 2 and blade 3.

Above-mentioned handle of a knife 1 comprises between the first handle plate 11 that is fastenedly connected and the second handle plate, 12, the first handle plates 11 and the second handle plate 12 and leaves the space; And the inboard that is provided with first stiffener, 13, the second handle plates 12, the inboard of the described first handle plate 11 is provided with second stiffener, 14, the first stiffeners 13 and second stiffener 14 is provided with in opposite directions.

Above-mentioned tool rest 2 is arranged in handle of a knife 1 space and with handle of a knife 1 and is slidingly connected, and blade 3 is installed in tool rest 2 one ends; And the inboard of described first stiffener 13 and second stiffener 14 is respectively equipped with a slide rail 15, two slide rails 15 are corresponding in opposite directions to be provided with, the both sides of tool rest 2 are respectively equipped with one and are embedded the slide block 21 that slides against in the slide rail 15, and slide block 21 can guarantee that with being used of slide rail 15 the mobile of tool rest 2 carries out according to setting track.

Above-mentioned tool rest 2 also is provided with the elasticity holding mechanism 4 that controls tool rest 2 and handle of a knife 1 locking or release with the correspondence position of handle of a knife 1, elasticity holding mechanism 4 comprises: elasticity push switch 41, its middle part is rotationally connected with the other end of tool rest, both ends are respectively press-side 411 and holding end 412, be provided with in the press-side 411 and guarantee that press-side 411 is tending towards elastic component upwards, holding end 412 is provided with the card protruding 414 that extends to elasticity push switch both sides; Draw-in groove 42, it is located at the top of first stiffener 13 and second stiffener 14, is used with card protruding 414.Wherein, described elastic component is a back-moving spring 413, and its two ends contact cooperation with press-side 411 bottoms with tool rest 2 contacts respectively; Described draw-in groove 42 is three pairs, every pair of corresponding in opposite directions respectively top of being located at first stiffener 13 and second stiffener 14 of draw-in groove 42.
