The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details, following explanation only is exemplary, does not limit protection scope of the present invention.

With reference to accompanying

drawing

1,2,3,4,5,6, the light-duty saddle of a kind of interchangeability can be applicable to 50# towing pin and 90# towing pin simultaneously; Comprise the latch hook 3 that is positioned at saddle main center and the horseshoe 7 that is welded as a whole with the saddle main body, the horseshoe mouth 11 that links to each other with horseshoe 7 and is positioned at horseshoe 7 back sides; Latch hook 3 is installed on the saddle main body through pressing plate 2, and the crotch of opening of horseshoe mouth 1 cooperates with the root of towing pin, and latch hook 3 cooperates with the neck of towing pin root below; Horseshoe mouth 1 comprises two covers with latch hook 3; Horseshoe mouth 1 detachably is installed on the horseshoe 7, and latch hook 3 links to each other with pressing plate 2 through detouchable, and pressing plate 2 is captiveed joint with the saddle main body; Two kinds of latch hook 3 thickness are identical and have an identical boss 5 of thickness that can remedy diff-H between two kinds of towing pins and the pressing plate 2; The boss 5 of the latch hook 3 of coupling 50# towing pin cooperates with 50# towing pin root, and the boss 5 of the latch hook 3 of coupling 90# towing pin cooperates with 90# towing pin top; The thickness of two breeds of horses hoof mouth 1 is the thickness of coupling 90# towing pin, just opens a grade diameter difference.
