The utility model relates to a single-edge folding knife. The utility model is characterized primarily in that a grab handle section is flat-shaped, a spring lamination is arranged on the grab handle section, and the edge of one side of the grab handle section is opposite to the edge of a blade and provided with a protective element which forms a sliver-shaped convex barrier strip. Thereby, the utility model has the advantage that the utility model guarantees the safety of using and carrying, and the edge of the blade is not easy to be damaged.
Description
The utility model relates to a kind of single-blade jack knife.
At present, the jack knife of commonly using 1, as Fig. 1, shown in 2, because of after long-term the use, causing distortion slightly or loosening unavoidably, cause the blade can't be closely superimposed when amounting to shank part 2 planes, and formation gap 21, when caused in gap 21, blade was in two and faces empty state when amounting to, and causing has at any time by the danger of blade incised wound, so, when the user is gripping or taking or when carrying jack knife, be easy to be hurt because of touching sharp sword accidentally, and when jack knife and other article are placed jointly, also can be hindered by its sharp sword, simultaneously, this sharp sword itself also may be because of being worn and torn with other blunt friction collisions; Moreover when this jack knife and other article were placed jointly, if the article that are flat or tapered are arranged, then the utmost point had and can insert gap 21, and gap 21 is become greatly gradually, caused distortion to reach to become flexible phenomenon to be on the rise, and then made jack knife danger more.
In view of this, the purpose of this utility model provides a kind of single-blade jack knife of improvement, and it is to be provided with protecting component on shank part, and sharp sword contacts with extraneous when amounting to block blade, avoids jack knife to hurt sb.'s feelings or thing.
The purpose of this utility model is achieved in that a kind of single-blade jack knife of improvement; comprise the blade that shank part and one end articulate; it is characterized in that: shank part is plane; and a shell fragment is set on it, on shank part one lateral edges relative, is provided with the protecting component of elongated protruding blend stop again with the sharp sword of blade.
Described protecting component is that arc line type, its this arc line type cross sectional dimensions of being in shank part one side projection are up big and down small, and and shank part on form a strip groove between the plane.
Described protecting component is made up of several sections strip blend stops separately.
Owing to adopt such scheme: guarantee the safety using and carry, simultaneously also easy damaged not of the sharp sword of blade.
