A foldable hanger, comprising: a hanger body; folding feet movably connected to the hanger body and having a supporting state after unfolding and a storing state after folding; a hanging and drying member movably connected to the hanger body and having a hanging and drying state distant from the hanger body and a resetting state close to the hanger body; and a linkage mechanism disposed between the folding feet and the hanging and drying member; a change of a state of any one of the folding feet and the hanging and drying member drives, through the linkage mechanism, a state of the other of the folding feet and the hanging and drying member to change; wherein the supporting state corresponds to the hanging and drying state, and the storing state corresponds to the resetting state; wherein the folding feet are hinged on the hanger body; the hanging and drying member has a sliding part which is in sliding fit with a slide rail disposed on the hanger body; the linkage mechanism converts a reciprocating rotation of the folding feet to a reciprocating sliding of the hanging and drying member or converts a reciprocating sliding of the hanging and drying member to a reciprocating rotation of the folding feet; the linkage mechanism is an inclined wedge mechanism; characterized in that: the inclined wedge mechanism comprises a linkage part disposed on the folding feet and a sliding block disposed on the hanger body; the sliding block is in bevel fit with the sliding part; a guide part cooperating with a guide structure disposed on the hanger body is disposed on the sliding block; the linkage part pushes the sliding block to move along the guide structure, and the sliding block drives the sliding part to move along the slide rail, so that the hanging and drying member moves to the hanging and drying state; on the contrary, the hanging and drying member drives the folding feet to move through the sliding part, the sliding block and the linkage part. a hanger body; folding feet movably connected to the hanger body and having a supporting state after unfolding and a storing state after folding; a hanging and drying member movably connected to the hanger body and having a hanging and drying state distant from the hanger body and a resetting state close to the hanger body; and a linkage mechanism disposed between the folding feet and the hanging and drying member; a change of a state of any one of the folding feet and the hanging and drying member drives, through the linkage mechanism, a state of the other of the folding feet and the hanging and drying member to change; wherein the supporting state corresponds to the hanging and drying state, and the storing state corresponds to the resetting state; wherein the folding feet are hinged on the hanger body; the hanging and drying member has a sliding part which is in sliding fit with a slide rail disposed on the hanger body; the linkage mechanism converts a reciprocating rotation of the folding feet to a reciprocating sliding of the hanging and drying member or converts a reciprocating sliding of the hanging and drying member to a reciprocating rotation of the folding feet; the linkage mechanism is an inclined wedge mechanism; characterized in that: the inclined wedge mechanism comprises a linkage part disposed on the folding feet and a sliding block disposed on the hanger body; the sliding block is in bevel fit with the sliding part; a guide part cooperating with a guide structure disposed on the hanger body is disposed on the sliding block; the linkage part pushes the sliding block to move along the guide structure, and the sliding block drives the sliding part to move along the slide rail, so that the hanging and drying member moves to the hanging and drying state; on the contrary, the hanging and drying member drives the folding feet to move through the sliding part, the sliding block and the linkage part.
