Abstract
The utility model belongs to the technical field of the hand tool technique and specifically relates to a double offset ring spanner in formula of controlling oneself, handle portion and head including integrated into one piece, the head includes plum blossom section and the changeover portion that is used for connecting plum blossom section and handle portion, the plum blossom section includes integrated into one piece's straight section and conic section, the contained angle alpha of the both sides line of conic section center cut is 7 -9. The utility model provides a double offset ring spanner in formula of controlling oneself, the plum blossom section has set up integrated into one piece's straight section and conic section, and the contained angle alpha of the both sides line of conic section center cut is 7 -9, and after the spanner inserted the screw head of a nail, conic section was owing to size difference, to the interior plum blossom formation extrusion of the head of a nail in the head of a nail to reach self -sustainedly, it is effectual to control oneself, and has the persistence.
Description
Technical field
The utility model relates to hand-operated tools technical field, double offset ring spanner in especially a kind of self-sustaining.
Background technology
Now, the frequency of utilization of plum blossom bolt or screw is more and more higher, conveniently assembling or dismounting, usually uses magnetic double offset ring spanner to adopt and is packed with magnetic material at its hand inner, make spanner knife bar have magnetic, thus held by screw.But due to this unreasonable structure, screwdriver rod is after using a period of time, and its magnetic can weaken and can not hold screw, does not reach the effect of magnetic screw driver, weak effect of controlling oneself.
Utility model content
The technical problems to be solved in the utility model is: in order to solve existing double offset ring spanner in use, after a period of time, its magnetic can weaken and can not hold screw, do not reach the effect of magnetic screw driver, the problem of self-holding weak effect, the utility model provides double offset ring spanner in a kind of self-sustaining, plum blossom section is provided with integrated straight section and cone section, the angle α in two sidelines of cone section central cross-section is 7-9 °, after spanner inserts the screw head of a nail, bore section in the head of a nail due to size difference, extruding is formed to plum blossom in the head of a nail, thus reach self-holding, control oneself effective, and there is persistence.
The utility model solves the technical scheme that its technical problem adopts: double offset ring spanner in a kind of self-sustaining, comprise integrated handle portion and head, described head comprises plum blossom section and the changeover portion for being connected plum blossom section and handle portion, described plum blossom section comprises integrated straight section and cone section, and the angle α in two sidelines of described cone section central cross-section is 7-9 °.
As preferably, the tapering of described changeover portion is identical with the tapering of cone section.
As preferably, the angle in two sidelines of described cone section central cross-section is 8 °.
The beneficial effects of the utility model are: the utility model provides double offset ring spanner in a kind of self-sustaining, plum blossom section is provided with integrated straight section and cone section, the angle α in two sidelines of cone section central cross-section is 7-9 °, after spanner inserts the screw head of a nail, cone section due to size difference, forms extruding to plum blossom in the head of a nail, thus reaches self-holding in the head of a nail, control oneself effective, and there is persistence.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of double offset ring spanner in self-sustaining of the present utility model.
Fig. 2 is the enlarged drawing at J position in Fig. 1;
Fig. 3 be in Fig. 2 A-A to sectional view.
In figure: 1. handle portion, 2. head, 21. plum blossom sections, 22. changeover portions, 211. straight sections, 212. cone sections.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1-Figure 3, double offset ring spanner in a kind of self-sustaining, comprise integrated handle portion 1 and head 2, head 2 comprises plum blossom section 21 and the changeover portion 22 for being connected plum blossom section 21 and handle portion 1, plum blossom section 21 comprises integrated straight section 211 and cone section 212, and the angle α in two sidelines of cone section 212 central cross-section is 7-9 °.
In this specific embodiment, the angle in two sidelines of cone section 212 central cross-section is preferably 8 °.
In a kind of detailed description of the invention, the tapering of changeover portion 22 is identical with the tapering of cone section 212.
In use, as long as the straight section 211 of double offset ring spanner in self-sustaining and cone section 212 are stretched into plum blossom screw nail tail successively, to screw extreme position, just can complete self-holding, wherein straight section 211 can ensure to assemble or the carrying out smoothly of knockout screw, and cone section 212 completes self-holding.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
