[0025] As Figures 1 to 5As shown, a folding support limiting structure, comprising a connecting seat 10, a foot pipe 20 rotatably connected to the connecting seat 10, the foot pipe 20 being rotatable relative to the connecting seat 10 to realize inward folding or outward unfolding, the connecting seat 10 being provided with a connecting cavity 110 corresponding to the foot pipe 20, the foot pipe 20 extending into the connecting cavity 110, the cavity wall of the connecting cavity 110 being provided with a first limiting part 120 for constraining the foot pipe 20 to fold inward, the first limiting part 120 abutting against the outer wall surface of the foot pipe 20, and the first limiting part 120 and the connecting seat 10 being of an integral structure. In this embodiment, the first limiting part is provided to abut against the foot pipe after the foot pipe is rotated outward to the maximum angle to constrain the foot pipe to rotate inward. When the foot pipe is folded, an acting force needs to be applied to the foot pipe, and when the acting force is greater than the constraining force of the first limiting part, the connecting seat and the first limiting part are deformed to provide the foot pipe with a space to rotate inward, so as to be folded. The first limiting part and the connecting seat are of an integral structure, which optimizes the assembly process, saves production cost, and does not need to press the elastic element when being unlocked, thereby being convenient to operate.

[0026] In use, the fan main body is fixedly installed on the connecting seat 10.

[0027] As shown in Figure 3 and Figure 4 , at least two first limiting parts 120 are provided in each connecting cavity 110, and the two first limiting parts 120 are arranged on the opposite cavity walls. The provision of the two first limiting parts 120 can effectively improve the constraining force to avoid the foot pipe 20 from being folded inward under other external forces, thereby improving the stability of the support.

[0028] As shown in Figure 5 , the connecting cavity 110 is provided with a second limiting part 130 for constraining the foot pipe 20 to rotate outward at a position outward of the connecting cavity 110, and the foot pipe 20 abuts against the second limiting part 130 when being unfolded outward to the maximum angle.

[0029] As shown in Figure 5 , in the supporting state, the foot pipe 20 is clamped by the first limiting part 120 and the second limiting part 130 to constrain the foot pipe 20 from rotating inward or outward.

[0030] As shown in Figure 5 , the end of the foot pipe 20 away from the connecting seat 10 is provided with an anti-skid foot pad 30.

[0031] As shown in Figure 3 and Figure 4 , the first limiting part 120 is in a semicircular structure. The semicircular structure is to facilitate folding deformation, so that when the foot pipe 20 is manually driven to fold inward, the semicircular first limiting part 120 is convenient for the foot pipe 20 to pass through to rotate to a completely folded position.

[0032] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
