The specific embodiment:
For further understanding structure of the present invention, feature and other purpose, now with as after preferred embodiment attached with graphic detailed description as after, only the illustrated embodiment of this legend is the usefulness for explanation, is not to be the unique restriction in the patent application.
Please cooperate and consult shown in Fig. 1-4, joint 10 of the present invention can with various instrument 20 mutual sockets, and its joint 10 has a drive end 11, its drive end 11 is in abutting connection with a fit portion 12 that is socketed on the instrument 20, and its fit portion 12 outer radius are concaved with a locating slot 120, holding firmware 30 for an elasticity half-turn shape snaps in the location, and has part to protrude locating slot 120 to locate with relative instrument 20 end face elasticity blockings.
And wherein, joint 10 mainly have one drive other workpiece drive end 11 and with the fit portion 12 of instrument 20 fits outside, one locating slot 120 is arranged in fit portion 12 in addition, and its locating slot 120 at least one side places are provided with the spline location division 121 of a straight form, and arbitrary of hexagonal end face that straight plane and joint 10 outsides are cut in its spline location division 121 becomes a parallel form.
And flexible holding firmware 30 main bodys are the structural form of C shape button, and the one end is set as a straight rotation prevention portion 31 with respect to aforesaid spline location division 121, its rotation prevention portion 31 extends the elastic fastening part 32 of an arc to the other end, and its arc radius is greater than locating slot 120, and forms the form of single-revolution in end.
When its holding firmware 30 was equipped in the locating slot 120 of instrument 20, its rotation prevention portion 31 was fastened with spline location division 121 on the locating slot 120, made its holding firmware 30 be positioned to keep on the joint 10 form of not rotating mutually.
Structural form so, the elastic fastening part 32 of its holding firmware 30 can be protruded out locating slot 120 by certain position, the rotation that unlikely generation is unnecessary, and when fashionable with instrument 20 covers, it is that confirmable elastic fastening part 32 cooperates with instrument 20 opposing end surface elasticity blockings, and reaches the function of high safety and high stability.
By aforesaid structure, can obtain following effect in fact, such as:
1, in conjunction with stable: the locating slot 120 of its holding firmware 30 and joint 10 combine stablizing very, do not have and rotate form improperly mutually, make whole integrated structure more stable certain, and reach the function of high stability.
2, joint is safe: because its holding firmware 30 is the form that maintenance is not rotated in joint 10 each other, so the position and the structure of holding firmware 30 protrusion joints 10 locating slots 120 must keep definite, be the state of the form of its protrusion in a best, so, when as shown in Figure 5, the elastic fastening part 32 of its holding firmware 30 is with the most definite position and instrument 20 relative position blockings, and purpose that reaches joint back high stability and high security that can be certain.
In sum, the present invention can reach above-mentioned all function really, so the present invention should accord with the patent application important document, files an application in accordance with the law.
