Description
Technical field
The utility model relates to a kind of folding cutter, is specially a kind of syndeton for 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 syndeton of location when blade launches, this syndeton also have simultaneously stability better, use light advantage.
The technical solution of the utility model is: a kind of syndeton for jackknife, it is characterized in that, comprise the connecting ring that is solidified as a whole with blade, be furnished with the locating piece of two projectioies at the anchor ring of described connecting ring, two locating pieces line centered by the axis of connecting ring, symmetric arrangement, described axis and blade are perpendicular.
Further technical scheme also is provided with positioning convex in the upper and lower end face of described connecting ring.
Further technical scheme, the upper and lower end face of described connecting ring is respectively arranged with two described positioning convex.
Further again, described positioning convex is rectangular block.
Further again, the thickness of described positioning convex is 0.5～1cm.
The utlity model has following beneficial effect:
1, accurate positioning: syndeton of the present utility model is by arranging locating piece at connecting ring, can after blade turns to the position of launching fully, be located and block, avoid its generation to rock, simultaneously, also by the side at connecting ring positioning convex is set, its detent with the handle of a knife inboard is matched, thereby further strengthened the accuracy of location.
2, stability better: because the utility model all is the location structure that adopts 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 used for the structural representation of the syndeton of jackknife for the utility model.
Fig. 2 is the structural representation with the supporting handle of a knife of the utility model syndeton.
Among the figure, 1-blade, 2-connecting ring, 3-handle of a knife, 4-positioning boss, 5-locating piece, 6-positioning convex, 7-locating hole, 8-blade groove, 9-detent.
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 syndeton for jackknife comprises the connecting ring 2 that is solidified as a whole with blade 1, and described connecting ring 2 is used for cooperating with locating hole 7 on the handle of a knife 3.During installation, alignd with locating hole 7 in the center of circle of connecting ring 2 on the blade 1, get final product by the rotating shaft connection then.Be provided with for the locating piece 5 that cooperates screens with the positioning boss 4 on the handle of a knife 3 at described connecting ring 2.In the utility model, locating piece 5 on the blade 1 is two and the symmetrical and arranged on left and right sides of being located at connecting ring 2, and 4 of positioning boss arrange one, when blade 1 turns to open mode, locating piece 5 and the positioning boss 4 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 4 on right side push against, and its position that pushes against just is that blade is taken in the position in the blade groove 8 fully.
Referring to Fig. 1 and Fig. 2, also be provided with positioning convex 6 in the side of described connecting ring 2, described positioning convex 6 be located at detent 9 on the handle of a knife 3 when being in deployed condition and folded state, cooperate chucking respectively.Described positioning convex 6 respectively has two on the upper ring surface of connecting ring 2 and following anchor ring.In the utility model, described positioning convex can 6 is rectangle, also can be circular or other shapes.Described positioning convex 6 on anchor ring separately all the center of circle with respect to described anchor ring be symmetrical arranged.Use for convenient, the degree of depth of described positioning convex 6 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 locating piece 5, has further strengthened locating effect by positioning convex 6 is set, and stability and durability are all better simultaneously.
Operation principle: when launching blade, locating piece 5 and the positioning boss 4 in connecting ring 2 left sides push against, and with blade 1 location, simultaneously, positioning convex 6 snaps in respectively in the corresponding detent 9, strengthens locating effect; When folding blade, locating piece 5 and the positioning boss 4 on connecting ring 2 right sides push against, and with blade 1 location, simultaneously, after positioning convex 6 reverse rotations, snap in respectively again in the corresponding detent 9, 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.
