For achieving the above object, the technical solution of the utility model is as follows:
A kind of leading screw is located fastening snap ring, comprise the clamp body one and the clamp body two that can be combined in together, one end of described clamp body one is circular shape, the end of circular arc is provided with barb, one end of described clamp body two is provided with the groove matching with described clamp body one, the end of groove is provided with the projection fastening with described barb, described clamp body one and clamp body two be capable of being combined, and to become one end be annulus, the other end is the integral body of cylinder, the inner ring of described annulus is positioned at the position that described projection and barb fasten and is provided with the opening one that can pass through for described projection, described cylinder is positioned at the position that described projection and barb fasten outward and is provided with the opening two that can pass through for described barb, the junction plane of described clamp body one and clamp body two is that to take the front end center of arc of barb be the center of circle, take one section of arc surface that center of arc is radius to the distance on the groove top of clamp body two, the bottom of described arc surface is connected with dentation Surface of action, the cylindrical end bottom of described clamp body one and clamp body two has ring-type draw-in groove.
Preferably, described dentation Surface of action is triangular structure, can guarantee in use between clamp body one and clamp body two, can not produce and relatively move.
Pass through technique scheme, the leading screw that the utility model provides is located fastening snap ring and is comprised clamp body one and the clamp body two can be combined in together, clamp body one and clamp body two can well be located leading screw by the combination of projection and barb, can not become flexible, good fixing effect, in conjunction with after integral body, its annulus is partly enclosed within the mounting groove on leading screw, leading screw can be rotated in annulus and can not swing and move, its column part navigates in leading screw mounting base by ring-type draw-in groove, its integral body is fixed, leading screw just can be because of stressed excessive not bending like this, leading screw all can not voluntary activity in all directions, good fixing effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the structural representation that the disclosed a kind of leading screw of the utility model embodiment is located fastening snap ring;
Fig. 2 is the plane structure schematic diagram that the disclosed leading screw of the utility model embodiment is located fastening snap ring;
Fig. 3 is the use view that the disclosed leading screw of the utility model embodiment is located fastening snap ring.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of leading screw to locate fastening snap ring, structure as shown in Figure 1, and this leading screw is located fastening snap ring and can effectively be fixed and protect leading screw, avoids bending when excessive stressed.
Leading screw is as depicted in figs. 1 and 2 located fastening snap ring, comprise the clamp body 1 and the clamp body 22 that can be combined in together, one end of clamp body 1 is circular shape, the end of circular arc is provided with barb 5, one end of clamp body 22 is provided with the groove 6 matching with clamp body 1, the end of groove 6 is provided with the projection 7 fastening with barb 5, clamp body 1 and clamp body 22 be capable of being combined, and to become one end be annulus, the other end is the integral body of cylinder, the inner ring of annulus is positioned at the position that projection 7 and barb 5 fasten and is provided with the opening 1 that can pass through for projection 7, cylinder is positioned at the position that projection 7 and barb 5 fasten outward and is provided with the opening 29 that can pass through for barb 5, the junction plane of clamp body 1 and clamp body 22 is that to take the front end center of arc of barb 5 be the center of circle, take one section of arc surface 10 that center of arc is radius to the distance on the groove top of clamp body 22, the bottom of arc surface 10 is connected with dentation Surface of action 11, dentation Surface of action 11 is triangular structure, can guarantee in use between clamp body 1 and clamp body 22, can not produce and relatively move.The cylindrical end bottom of clamp body 1 and clamp body 22 has ring-type draw-in groove 12.
