Snap ring for quickly installing safety air bag generator

The utility model relates to the technical field of safety air bag maintenance, in particular to a quick installation clamping ring for a safety air bag generator. The clamping ring comprises a mounting device and a clamping device arranged on the periphery of the mounting device, the mounting device comprises a connecting column and a connecting pipe, and a pressure cavity is formed in the connecting column. Meanwhile, the sliding block is ejected out by high-pressure gas and clamped at the bottom of the mounting plate, high-pressure gas in a pressure cavity is exhausted through a connecting pipe, chippings between the mounting plate and the generator are removed, and the problems that a threaded groove in the mounting plate is prone to being damaged, so that bolts cannot be fixed, and when the gas generator is replaced, the bolts cannot be fixed are solved. And disintegrating slag caused by last detonation is easy to remain between the gas generator and the bottom plate, so that a gap is easy to generate du
