The specific embodiment

See also Fig. 3 and shown in Figure 4, be the outward appearance combination and the exploded view of a kind of tool-joint safety of the utility model and quick releasing structure, it consists predominantly of a body 20 and a set of joints 30 is formed;

This body 20, its front end edge axially is concaved with a group-connecting groove 21 with open end, the side of this group-connecting groove 21 is provided with two relative spacing holes 22, the bottom of this spacing hole 22 is provided with one towards group-connecting groove 21 and is one first limiting section 221 of perforation, and the aperture of this first limiting section 221 is less than spacing hole 22, one flexible member 23 is constituted by a spring, this flexible member 23 places this spacing hole 22 near these group-connecting groove 21 ends, one locating part 24, it is that the steel ball of an orbicule is slidedly arranged in this spacing hole 22, this flexible member 23 and elasticity compress this locating part 24, after treating that this flexible member 23 and this locating part 24 are mounted in this spacing hole 22, establish in the open top side ring of spacing hole 22 again and form one second limiting section 222, the punching press point that this second limiting section 222 forms for punching press, the diameter of this locating part 24 and greater than this first limiting section 221 and this second limiting section 222, make this locating part 24 can be subjected to the spacing of this first limiting section 221 and this second limiting section 222, but this locating part 24 can slightly protrude from this first limiting section 221 and second limiting section 222.

This set of joints 30, its front end are a tool heads 31, and it can be instrument like the various associated class such as spanner, bottle opener, sleeve, and the rear end is provided with a connection terminal 32 and establishes for 21 groups with this group-connecting groove, on this connection terminal 32 and convex with an elastic projection 33.

By for further understanding the effect that the utility model structural feature, application technology means and institute's expection are reached, now the utility model occupation mode is narrated, believing be able to have more deep and concrete understanding to the utility model therefrom, as described below:

Still see also Fig. 4 to shown in Figure 6, when these body 20 windings have this set of joints 30, but the spacing hole 22 of these group-connecting groove 21 both sides is this elastic projection 33 of socket all, make this set of joints 30 be easy to install, this locating part 24 can be subjected to the resilient force of this flexible member 23 and be slightly protruding in second limiting section 222, make this locating part 24 not influence the installation of this set of joints 30, promptly finish after the elastic projection 33 elasticity cards of this set of joints 30 are established in this spacing hole 22 and connect and fix, when needing this set of joints 30 of dismounting, the application of force is pushed the elastic force that this locating part 24 overcomes this flexible member 23, make the bottom surface of this locating part 24 can compress this elastic projection 33 these spacing holes 22 of disengaging, after this set of joints 30 breaks away from, stop after the application of force this locating part 24 and can be subjected to the elastic force of this flexible member 23 and rebound.

See also Fig. 7 to shown in Figure 8, the utility model provides another embodiment of a kind of tool-joint safety and quick releasing structure, its primary structure and last embodiment are together, so repeat no more, be primarily characterized in that, only be provided with locating part 24 in this spacing hole 22, when this locating part 24 is not installed in this set of joints 30, this locating part 24 can fall within the bottom of spacing hole 22 because of deadweight, during these set of joints 30 windings, because the surface of this locating part 24 is an arc surface,, can avoid this locating part 24 to limit the installation of this set of joints 30 so this locating part 24 can slide with the surface of this connection terminal 32, and in this elastic projection 33 is installed on this spacing hole 22 time, this elastic projection 33 can natures with these locating part 24 pushing tows, the end face of this locating part 24 is protruded, push in the time of can be for convenience detach.

Now, again feature of the present utility model and attainable expection effect thereof are presented below:

1. tool-joint safety of the present utility model and quick releasing structure, its locating part is limited in this spacing hole by this first limiting section and second limiting section, and when making, only need after this locating part is inserted spacing hole, forming second limiting section with impact style gets final product, its manufacture process is simple, can reduce manufacturing cost.

2. tool-joint safety of the present utility model and quick releasing structure, its locating part is constituted by steel ball, it is in set of joints is mounted on group-connecting groove the time, because of the surface of locating part is an arc surface, this limiting section can slide with the surface of this set of joints, make this locating part not influence installation, can increase the convenience that the user installs.

3. tool-joint safety of the present utility model and quick releasing structure, its locating part are steel ball, and it is general commonly used article, and its specification is complete and obtain easily, can reduce cost of processing and complexity.

In sum, the utility model has its splendid progressive practicality in fact in like product, simultaneously all over looking into domestic and international technical data about this class formation, also finding no identical construction in the document exists formerly, so, the utility model is real to have possessed the utility model patent important document, files an application in accordance with the law.

The above only is of the present utility model one preferable possible embodiments, changes so use the equivalent structure that the utility model specification and claim do such as, ought to be included in the claim of the present utility model.
