Description
Technical field
The utility model relates to the parts of cutter, is specially a kind of spacing handle of a knife of jackknife, belongs to the daily living article technical field.
Background technology
In people's daily life, the use of cutter is very general, as fruit knife etc., deposits and avoid accidentally injuring the people for convenience, and most of small-sized cutters all are designed to foldable structure, like this can be with its folding after using.Existing folding cutter normally is made of handle of a knife and blade, and blade is rotatable to be connected on the handle of a knife, is provided with in handle of a knife be used to the groove of depositing blade.Now at present when blade and handle of a knife are installed, great majority are to adopt lock-button that the two is coupled together, and also be with spring and realize location to blade on lock-button.But owing to the elastic force of spring can weaken gradually along with the frequent use of cutter, so traditional jackknife in use for some time, and blade can become loosening after launching, and is difficult to its accurate location, can influence the normal use of cutter like this.If want to make the blade rechuck, the most frequently used method is exactly to realize by the elastic force of reinforcement spring, requires great effort very much but this can cause again when the open and close cutter, has also brought inconvenience for the user.
The utility model content
At above-mentioned deficiency of the prior art, main purpose of the present utility model be to provide a kind of can be with its accurate spacing handle of a knife of location when blade launches, this spacing handle of a knife also have simultaneously stability better, use light advantage.
The technical solution of the utility model is: a kind of spacing handle of a knife of jackknife, comprise the handle of a knife that is provided with the blade groove, two sidewalls at the blade groove are provided with for the locating hole that connects blade, it is characterized in that, be provided with positioning boss in the blade groove, this positioning boss is positioned at blade groove inwall and close described locating hole.
Further technical scheme also is provided with detent in two inside sidewalls of described blade groove.
Further technical scheme respectively is provided with two detents in two inside sidewalls of blade groove.
Further again, described detent is bar-shaped trough, and its cross section is rectangle.
Further again, described detent is arranged in parallel in the both sides of described locating hole.
Further again, the degree of depth of described detent is 0.5～1cm.
The utlity model has following beneficial effect:
1, accurate positioning: spacing handle of a knife of the present utility model is by arranging positioning boss in the handle of a knife inboard, can reach with corresponding blade on locating piece cooperate chucking, can after blade turns to the position of launching fully, be located like this and block, avoid its generation to rock, simultaneously, also by the medial surface at spacing handle of a knife detent is set, it is matched with positioning convex on the blade connecting ring, thereby further strengthened the accuracy of location.
2, stability better: because handle of a knife of the present utility model adopts the location structure of clamping, the stability after cutter launches can not be subjected to the influence of service time and fluff movingly, therefore has job stability preferably.
3, easy to use, laborsaving, only the less power of need just can realize the expansion of cutter and fold.
Description of drawings
Fig. 1 is the structural representation of the spacing handle of a knife of the utility model jackknife.
Fig. 2 is the edge structure schematic diagram supporting with spacing handle of a knife of the present utility model.
Among the figure, 1-blade groove, 2-handle of a knife, 3-blade, 4-locating hole, 5-locating piece, 6-positioning boss, 7-detent, 8-connecting ring, 9-positioning convex.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As depicted in figs. 1 and 2, a kind of spacing handle of a knife of jackknife comprises the handle of a knife 2 that is provided with blade groove 1, and described blade groove 1 is used for placing blade 3 when folding.Be provided with for the locating hole 4 that connects blade 3 at handle of a knife 2, during installation, alignd with locating hole 4 in the center of circle of connecting ring 8 on the blade 3, get final product by the rotating shaft connection then.In handle of a knife 2, be provided with for the positioning boss 6 that cooperates screens with the locating piece 5 on the blade 3.In the utility model, locating piece 5 on the blade 3 is two and the symmetrical left and right side of being located at connecting ring 8, and 6 of positioning boss arrange one, when blade 3 turns to open mode, locating piece 5 and the positioning boss 6 in left side push against, thereby the angle to blade is spacing, and at this moment blade and handle of a knife are straight line substantially; When folding blade, locating piece 5 and the positioning boss 6 on right side push against, and its position that pushes against just is that blade is taken in the position in the blade groove 1 fully.
Referring to Fig. 1 and Fig. 2, also be provided with detent 7 at the medial surface of described blade groove 1, described detent 7 be located at positioning convex 9 on the connecting ring 8 when being in deployed condition and folded state, cooperate chucking respectively.In the utility model, on medial surface on the blade groove 1 and following medial surface, respectively be provided with two detents 7.Described detent 7 can be rectangle, also can be circular or other shapes.Described detent 7 respectively on place medial surface separately the center with respect to locating hole 4 be symmetrical arranged.Use for convenient, the degree of depth of described detent 7 is 0.5～1cm, when expansion and closed blade, can not require great effort very much like this, also can play stable locating effect simultaneously.The utility model on the basis, location of positioning boss 6, has further strengthened locating effect by detent 7 is set, and stability and durability are all better simultaneously.
Operation principle: when launching blade, locating piece 5 and the positioning boss 6 in connecting ring 8 left sides push against, and with blade 3 location, simultaneously, positioning convex 9 snaps in respectively in the corresponding detent 7, strengthens locating effect; When folding blade, locating piece 5 and the positioning boss 6 on connecting ring 8 right sides push against, and with blade 3 location, simultaneously, after positioning convex 9 reverse rotations, snap in respectively again in the corresponding detent 7, realize locating.
Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, although the applicant has been described in detail the utility model with reference to preferred embodiment, those skilled in the art is to be understood that, those are made amendment to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of the claim scope of the present utility model.
