Abstract

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 single-blade jack knife of improvement

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.

Below in conjunction with drawings and Examples the utility model is further specified.

The jack knife outside drawing that Fig. 1 commonly uses;

The jack knife side schematic view that Fig. 2 commonly uses;

Fig. 3 is the utility model first embodiment outside drawing;

Fig. 4 is the utility model second embodiment outside drawing;

Fig. 5 is the A enlarged drawing of the utility model second embodiment Fig. 4;

Fig. 6 is the utility model the 3rd embodiment outside drawing;

Among the figure: 30. shank parts, 31. blades, 312. sharp swords, 34. protecting components

First embodiment, as shown in Figure 3, this jack knife 3 is to be provided with a slice to be plate shaped shank part 30, one end appropriate position of this shank part 30 is pivoted with a blade 31, this shank part 30 is provided with the hole of a hollow out in the appropriate position of adjacent central, make shank part 30 below form a shell fragment 32, the one end system of this shell fragment 32 is upwards and curved slightly shape, to make it have elasticity, and then make shell fragment 32 form a stop section 33 at the one end, this stop section 33 just can lean with open blade 31 bottom ora terminalis 311, is fixed can borrow stop section 33 after making this blade 31 open.

Shank part 30 when blade 31 is amounted to and the side faced of sharp sword 312 places of blade 31 be provided with a protecting component 34 along the edge.This protecting component 34 is elongated and has the blend stop of height slightly; when blade 31 is amounted to; protecting component 34 just can block the sharp sword 312 of blade 31; sharp sword 312 can't be contacted with the external world fully; that is no matter the user is to grip; take or when carrying jack knife 3; all can keeping out because of protecting component 34; and can not touch sharp sword 312; and other and this jack knife 3 common article of placing also can not hindered by sharp sword 312; simultaneously; this sharp sword 312 itself also can exempt from other blunts and decrease, so protecting component 34 can reach the purpose of protection user's hand and sharp sword 312 itself simultaneously.

Second embodiment; as shown in Figure 4; protecting component 40 also can be elongated and has blend stop 41 highly slightly; this blend stop 41 is to be from bottom to top and towards the camber line shape of shank part direction on a side of relative shank part 4; this camber line shape extends to form up big and down small protecting component 40 gradually; make and form a strip groove 42 between protecting component 40 and shank part 4 planes; when blade is amounted to; sharp sword can embed in the groove 42 fully; make it except that avoiding sharp sword hurts sb.'s feelings, also can prevent the problem of excesssive gap between blade and the shank part 4.

The 3rd embodiment; as shown in Figure 5, protecting component 50 also can be had highly and be the strip blend stop 51 of equidistant arrangement, spacing 52 sizes of this blend stop 51 by several shows; to guarantee that the user is difficult for touching sharp sword and causes injured to be the suitable distance of principle, to make protecting component 50 can bring into play protective effect.
