[0008] The upper surface of the support platform is also equipped with a platform cover, and the lower surface of the platform cover is provided with a connecting rod with 1 / 4 thread. The connecting rod connects the platform cover to the support platform through a connecting port.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] After installing our extension bracket onto the 1 / 4" threaded female connector, a small mounting platform is formed. The platform itself is made of iron, allowing small accessories such as wireless switches and fragrance boxes to be magnetically attached to it. The extension bracket also features a built-in 1 / 4" female connector, enabling the attachment of cameras, shooting stands, and decorative items with 1 / 4" threaded adapters. A rotating mechanism allows for adjustment of the device's viewing angle for easier operation. A decorative cover is also provided; users who do not need the 1 / 4" threaded connector can screw the cover on top for concealment. The cover, also made of iron, serves not only a decorative function but also accommodates magnetic devices such as wireless switches and fragrance boxes, making it both aesthetically pleasing and convenient to use.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] like Figures 1 to 6As shown, a multi-purpose extension bracket with a 1 / 4 threaded port includes: a bracket platform 1, a base 2, and a base connecting rod 4. The base connecting rod 4 has a 1 / 4 thread and is located on the lower end face of the base 2 for connection with the 1 / 4 threaded port of an automobile or small installation platform. The bracket platform 1 and the base 2 are rotatably connected. The bottom of the bracket platform 1 is connected to a rotating wheel 15 via a vertical rod. The rotating wheel 15 is also provided with teeth for limiting its position using a limiting device. A circular groove 13 is provided on the lower end face of the rotating wheel 15. The base 2 is a hollow structure. A circular base groove 21 is provided at the bottom of the hollow cavity of the base 2. The groove 13 and the base groove 21 are the same size and are matched for installation. A ball bearing 24 is provided in the base groove 21. Under the action of the ball bearing 24, the bracket platform 1 can rotate on the base 2 to adjust the appropriate direction for using the equipment installed on the bracket platform 1.

[0022] The base 2 is also equipped with a base cover 22. A limit button 3 is provided through the upper surface of the base cover 22. A limit pin 31 is connected below the limit button 3. The bottom surface of the cavity of the base cover 22 is also provided with a slot 23 that matches the size and position of the limit pin 31. A spring is provided in the slot 23. The lower end of the spring abuts against the bottom surface of the slot 23, and the upper end of the spring abuts against the limit pin 31. Under normal conditions, the limit pin 31 is inserted into the toothed opening of the rotating wheel 15, locking the rotating wheel and preventing it from rotating, thus playing a limiting role. When the user needs to rotate the support platform 1 to adjust the usage angle, press the limit button 3. The limit pin 31 leaves the toothed opening of the rotating wheel 15 and moves into the slot 23. At this time, the support platform 1 can rotate 360 ​​degrees automatically. At the same time, the spring is compressed. When the appropriate angle is adjusted, the limit button 3 is released. Under the elastic force of the spring, the limit pin 31 is inserted back into the toothed opening of the rotating wheel 15 to limit it.

[0023] The upper end face of the support platform 1 is provided with a connection port 12, and the inner wall of the connection port 12 is provided with a 1 / 4 thread for connecting equipment with a 1 / 4 thread. The upper end face of the support platform 1 is also equipped with a platform cover 11, and the lower end face of the platform cover 11 is provided with a connecting rod 14 with a 1 / 4 thread. The connecting rod 14 connects the platform cover 11 to the support platform 1 through the connection port 12. When the user needs to connect the equipment, the platform cover 11 can be rotated to remove it from the support platform 1. Then, by connecting the 1 / 4 thread on the equipment to the connection port 12 on the support platform 1, the equipment can be installed on the support platform 1 for use. When not in use, the platform cover 11 can be reinstalled to make the overall appearance more aesthetically pleasing. At the same time, the platform cover 11 is made of iron and can also be used with some magnetic devices.
