The barrier-free detachable air outlet clamping device of claim 1, wherein the hook is hinged to the front end of the outer casing, and the hooks are respectively located in front of the hinged positions of the hooks. , the top receiving part and the hook part on the rear side, a second elastic member is arranged between the hook and the outer casing, and the second elastic member acts on the hook to provide a restoring force that makes the hook expand outward;

When the hook is folded, the inner rod moves forward relative to the outer casing, so that: the front end of the inner rod pushes the receiving top of the hook to rotate outward, and the hook part of the hook rotates and folds inward synchronously;

When the hook is unfolded, the inner rod moves backward relative to the outer casing, so that: the front end of the inner rod releases the top push action on the hook, and the hook portion of the hook is extended out by the reset action of the second elastic member .
