[0013] (III) Beneficial effects: Compared with the prior art, the present utility model provides a multi-functional fan bracket, which has the following beneficial effects:

[0014] 1. For this multi-functional fan bracket, due to the good deformation ability of the support frame, the fan bracket can adapt to a variety of usage scenarios. Whether it is placed on a table as a desktop fan, or clipped on an arm or other linear objects as a portable fan, or even passed through a hook as a ceiling fan, it can be easily achieved. The lightweight aluminum material and the bendable design make the whole fan bracket very portable. Users can easily put it into a backpack or handbag and enjoy the coolness anytime and anywhere. Although the support frame can be bent, the high strength of the aluminum material and the stability of the wrapping colloid ensure sufficient supporting force in different usage scenarios, guaranteeing the stable operation of the fan. The existence of the wrapping colloid not only increases the comfort of use, but also reduces noise and vibration, providing a more pleasant user experience for users. The corrosion resistance of the aluminum material and the protection of the wrapping colloid make this fan bracket have high durability and can withstand long-term use and various environmental tests.

[0015] 2. For this multi-functional fan bracket, through the combined design of the lower rotating bracket and the upper rotating bracket, the flexible adjustment of the tilt angle of the fan bracket is realized. Users can adjust the blowing angle of the fan according to actual needs to obtain the best usage effect. The close fit between the spherical end of the support frame and the installation groove, as well as the matching design of the end support and the groove, ensure the stability of the fan bracket during rotation. Even after adjusting the angle, it can maintain a stable supporting state. The design of the whole connection structure is simple and clear, and users can easily complete the installation and adjustment without complex operations. At the same time, the smoothness of the rotation mechanism also improves the user experience.

[0016] 3. The multifunctional fan bracket has a detachable structure design, making the assembly process of the fan bracket more flexible and convenient. Users can easily connect the spherical end with the aluminum bar according to their needs, without complex welding or fixing processes. When the support frame needs to be replaced or repaired, users can simply disassemble the spherical end instead of replacing the entire fan bracket, thus reducing maintenance costs and time. The spherical end is fixed by screwing through the end of the aluminum bar and the screw holes of the spherical end, ensuring a firm connection between the spherical end and the aluminum bar. This mechanical fixing method is more reliable than simple snap or friction connections and can withstand greater forces and torques, guaranteeing the stability of the fan bracket during use. The detachable spherical end design allows users to choose aluminum bars of different lengths, shapes, or materials for replacement according to different usage scenarios and requirements. This flexibility improves the adaptability of the fan bracket, enabling it to be applicable to more installation environments and conditions. The design of inserting the aluminum bar into the spherical end helps optimize the weight distribution of the entire support frame. As the main load-bearing component, the position of the aluminum bar can be adjusted according to needs to ensure that the fan bracket remains balanced and stable at different angles and positions.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer toFigure 1 - Figure 2 , a multi-functional fan bracket, including a support frame 1, a fan base 4 and a fan 5. The fan 5 is installed on the fan base 4, and the fan base 4 is connected to the support frame 1 through a connection structure. The support frame 1 is in the shape of a foot and has at least three. The support frame 1 is composed of an aluminum strip 111 and a wrapping colloid 11. The wrapping colloid 11 wraps the aluminum strip 111 inside. The aluminum strip 111 and the wrapping colloid 11 can be bent to change the shape, and the inclination angle between the support frame 1 and the connection structure can be adjusted.

[0025] By wrapping the aluminum strip 111 inside the wrapping colloid 11, the support frame 1 under the fan 5 can have a certain deformation ability while providing support. Through manual bending and clamping, it can be used in different scenarios. For example, when placed upright, it can be used on a desktop; when bent, it can be clamped on the arm or other linear objects; it can also be passed through a hook to be used as a ceiling fan. Using aluminum as the main material of the support frame 1 is because aluminum has the characteristics of light weight, high strength and good plasticity. This enables the aluminum strip 111 to maintain sufficient support force while also being able to be bent by hand or simple tools to adapt to different usage scenarios. The wrapping colloid is used to cover the aluminum strip, which not only increases the comfort of use (avoiding the discomfort that may be brought by direct contact with metal), but also provides additional protection to prevent the aluminum strip from scratching or damaging other items during use. At the same time, the wrapping colloid 11 also plays a certain buffering role, making the bending process smoother and reducing the friction and noise between metals. The support frame 1 is designed in the shape of a foot and has at least three feet. Such a design not only ensures stability but also facilitates adapting to different installation environments by adjusting the angles and positions between the feet.

[0026] Refer to Figure 3 , the connection structure is composed of a lower rotating bracket 2 and an upper rotating bracket 3. The lower rotating bracket 2 and the upper rotating bracket 3 are in a circular ring shape. The lower rotating bracket 2 is provided with an installation groove 21 on the side for the support frame 1 to be inserted, and a cylindrical connection column for connecting with the upper rotating bracket 3 is provided above the lower rotating bracket 2.

[0027] Refer to Figure 3 - Figure 5 , the end of the support frame 1 is provided with a spherical end 12. The shape of the spherical end 12 is the same as that of the installation groove 21. A cylindrical end fulcrum 122 is provided on the side of the spherical end 12. A groove for placing the end fulcrum 122 is provided on the side of the installation groove 21, enabling the support frame 1 to rotate around the axis of the end fulcrum 122. The spherical end 12, the wrapping colloid 11 and the aluminum strip 111 are detachable structures. The aluminum strip 111 can penetrate into the spherical end 12, and screw holes for the screw 121 to pass through are provided on the end of the aluminum strip 111 and the spherical body of the spherical end 12.

[0028] The fan base 4 is crescent-shaped and fixes the fan 5 through the two side endpoints. Rotating shafts are arranged inside the two fixing points on the sides, enabling the fan 5 to adjust its angle.

[0029] The wrapping colloid 11 is made of polyvinyl chloride. PVC (polyvinyl chloride) is a common plastic material with good corrosion resistance, insulation, and mechanical strength. Coating the surface of aluminum products with PVC can form a protective film, which not only improves the rust and corrosion resistance of the aluminum strips but also increases their flexibility to a certain extent, making them easier to bend and fix.

[0030] Working principle: The fan 5 is installed on the fan base 4. The fan base 4 is connected to the support frame 1 through a connection structure. The support frame 1 is in the shape of a foot and has at least three. The support frame 1 is composed of an aluminum strip 111 and a wrapping colloid 11. The wrapping colloid 11 wraps the aluminum strip 111 inside. The aluminum strip 111 and the wrapping colloid 11 can be bent to change their shapes. The inclination angle between the support frame 1 and the connection structure can be adjusted. By wrapping the aluminum strip 111 inside the wrapping colloid 11, the support frame 1 under the fan 5 can have a certain deformation ability while providing support. Through manual bending and clamping, it can be used in different scenarios. For example, when placed upright, it can be used on a table; when bent, it can be clamped on the arm or other linear objects; it can also be passed through a hook to be used as a ceiling fan. Using aluminum as the main material for the support frame 1 is because aluminum has the characteristics of light weight, high strength, and good plasticity. This enables the aluminum strip 111 to maintain sufficient supporting force while being bent by hand or simple tools to adapt to different usage scenarios. The wrapping colloid is used to cover the aluminum strip, which not only increases the comfort of use (avoiding discomfort that may be caused by direct contact with metal) but also provides additional protection to prevent the aluminum strip from scratching or damaging other items during use. At the same time, the wrapping colloid 11 also plays a certain buffering role, making the bending process smoother and reducing the friction and noise between metals. The support frame 1 is designed in the shape of a foot and has at least three feet. Such a design not only ensures stability but also facilitates adapting to different installation environments by adjusting the angles and positions between the feet.
