[0030] The top of the fixed base is provided with an inner mounting groove 8 extending downward, and the front of the fixed base is provided with a slide groove 9 connected to the inner mounting groove. The back of the fixed base is provided with an outer mounting groove 10 recessed inward, and a limit support plate 11 is installed in the middle of the outer mounting groove. The bottom of the fixed base is provided with a spiral support column 12 and a chassis 13 located at the bottom of the spiral support column. The top of the spiral support column is connected to the limit support plate, and the outside of the spiral support column is provided with an external thread. A threaded hole matching the spiral support column is provided on the bottom surface of the fixed base located at the bottom of the outer mounting groove, and the spiral support column passes through the threaded hole.

[0031] The first folding arm and the second folding arm include a pair of support rods 14, and a lower fixed arm is hinged at the bottom end of the first folding arm. The lower fixed arm is composed of a pair of plates 16, and the pair of plates are connected together by fasteners 17. The lower fixed arm is assembled in the inner mounting groove through a nut and bolt structure, and a limit rod 18 is hinged on one of the plates of the fasteners, and a cross bar 19 is installed on the top of the limit rod. The cross bar is used to hinge a support rod of the first folding arm to limit the deflection of the first folding arm. A first hinge seat 20 is provided at one end of the second folding arm close to the first folding arm, and a second hinge seat 21 is provided at one end of the second folding arm away from the first folding arm.

[0032] The fan bracket comprises a fan clip 22 and a bracket seat 23, wherein the fan clip is mounted on the bracket seat, and the bottom end of the bracket seat is mounted on the second hinge seat. A reinforcing rod 15 is connected to the first hinge seat, and the reinforcing rod is connected to one of the supporting rods on the second folding arm.

[0033] When this embodiment is implemented, the limit support plate is pushed up and down by rotating the spiral support column, so that the limit support plate and the fixed base are clamped on the bedside. The first folding arm and the second folding arm are rotated to achieve the folding angle, and the cross bar of the limit rod is used to hinge a support rod of the first folding arm to limit the deflection of the first folding arm.

[0034] Example 2

[0035] The difference between this embodiment 2 and embodiment 1 is that Figure 2 As shown, the limit support plate is a cylinder, and the limit support plate includes a first component 24 and a second component 25, the first component is located on the upper part of the second component, the second component is connected to the spiral support column, the second component is made of hard material, and the first component is made of elastic material.

[0036] When this embodiment is implemented, as the rotating spiral support column pushes the limit support plate to move upward, its first component contacts the edge of the bed. Here, the curvature of the first curved surface is smaller than the curvature of the second curved surface. When the limit support plate rotates unidirectionally, the edge of the bed slides into the first curved surface and the second curved surface of the buffer component in sequence in one direction, which facilitates the edge of the bed to be stuck in the engaging groove of the deformed buffer component and limits the reverse deflection of the limit support plate. It can adapt to the edges of beds of different shapes.
