In the process of installation, when the rotating rod 4 is in a horizontal state, the rotating rod 4 is positioned above the connecting part 2, the short section 42 of the rotating rod 4 is close to the connecting part 2, and the short section 42 of the rotating rod 4 is turned upwards under the action of gravity to complete the switching from the horizontal state to the vertical state; in the process of disassembly, the clamping part 3 is firstly adjusted to be far away from the rotating rod 4, so that the connecting part 2 can rotate in a screw hole of a wall body, then the connecting part 2 is manually turned over, so that the connecting part 2 is turned over for 180 degrees in the vertical direction, and the rotating rod 4 in the vertical state is driven by the connecting part 2 to turn over the long section 41 to be right above the short section; after the overturning, the connecting part 2 is pushed in the horizontal direction to enable the rotating rod 4 to be far away from the wall body, the long section 41 overturns downwards under the action of gravity, the section is close to the connecting part 2 when the rotating rod 4 is in the horizontal state, the rotating rod 4 is located below the connecting part 2, the connecting part 2 plays a limiting role in the rotating rod 4 to keep the horizontal state, and finally the connecting part 2 is pulled out to finish the disassembling.

As an optional embodiment of the present invention, the cross section of the short segment 42 is semicircular, the cross section of the connecting portion 2 near one end of the rotating rod 4 is semicircular, and when the rotating rod 4 is in the horizontal state, the short segment 42 and the connecting portion 2 are overlapped and spliced into a cylinder. The splicing position of the rotary rod 4 and the connecting part 2 in the horizontal state is smoother, and the dismounting and mounting process is smoother.

As an optional implementation manner of the present invention, in the width direction of the rotating rod 4, the hinge point of the rotating rod 4 and the connecting portion 2 is located at the eccentric position of the rotating rod 4 and is closer to the wall body of the installation, so that the long section 41 turned over to the top has a greater probability to turn over in the direction away from the wall body in the detaching process, which is beneficial to the quick switch from the vertical state to the horizontal state of the rotating rod 4.

As an alternative embodiment of the present invention, the connecting portion 2 is rod-shaped.

As an optional embodiment of the present invention, the hook portion 1 and the connecting portion 2 are an integral structure, and the hook portion 1 is bent at 90 degrees; adopt integrated into one piece structure to have firmly durable and the low advantage of finished product processing.

As an optional embodiment of the present invention, the clamping portion 3 is a nut, and the end of the connecting portion 2 away from the rotating rod 4 is provided with a thread matching with the nut.

As an alternative embodiment of the present invention, one side of the nut near the installation wall is provided with a gasket, and the outer diameter of the gasket is larger than the diameter of the screw hole of the wall.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
