[0035] By pulling the two side plates 7 outward at the same time, the two positioning slide bars 5 equipped with the second connecting spring 6 can be driven to retract, and then the embedded seat 4 is clamped into the inside of the key chain body 1, and then the two positioning slide bars 5 are released, so that the elastic positioning slide bars 5 will automatically extend and insert into the two ends of the embedded seat 4, so as to preliminarily clamp and fix the embedded seat 4, and then the four telescopic blocks 11 at the cross clamping plate 9 are stretched and clamped into the inside of the fixed block 10, which is conducive to further assembly and installation of the entire combination key chain, ensuring the stability of the combination key chain structure during installation, so that there is no need to use an annular ring to load and unload the key, making the combination key chain more convenient to disassemble and use, and at the same time can also increase the service life of the combination key chain;

[0036] By putting the key onto the first iron ring 14, and then rotating the second iron ring 15 at the first iron ring 14 to the inside of the two support plates 16, the threaded rod 17 is simultaneously clamped into the second iron ring 15 and the support plate 16 to clamp and fix the first iron ring 14 and the second iron ring 15, and then the protrusion 19 at the fastening nut 18 can be easily used to lock the threaded rod 17, so that the key can be stably and reliably fixed in the two iron rings. At the same time, the two groups of iron rings can be classified and assembled for the keys, making the use of the key chain more flexible and changeable, and then the stopper 8 at the connecting member 2 can be used to limit the opening of the key chain body 1, and then the rotating plate 21 is rotated so that the rubber connecting block 22 at the rotating plate 21 can be embedded in the U-shaped plate 20, so as to fix the combination key chain for the second time, so that the combination key chain can be firmly hung on the trousers button.
