[0026] Reference Figures 1 to 2 , a universal bracket, including a base 10, a sleeve 20, a ball head 30, a limit assembly 40 and a locking knob 50;

[0027] A threaded column 11 is provided on the base 10;

[0028] A spherical cavity 21 is provided in the sleeve 20 and passes through it vertically;

[0029] The ball head 30 is disposed in the spherical cavity 21 , and the device can be mounted on the ball head 30 ;

[0030] The limiting assembly 40 is disposed between the upper end surface of the threaded column 11 and the lower end surface of the sleeve 20 to limit the relative rotation between the sleeve 20 and the base 10;

[0031] A threaded groove 51 is provided on the inner wall of the locking knob 50;

[0032] The locking knob 50 can push the sleeve 20 to abut against the ball head 30 when the threaded column 11 is threadedly connected to the threaded groove 51 , so as to limit the relative rotation between the ball head 30 and the base 10 .

[0033] In the present invention, during assembly, the ball head 30 is first placed in the spherical cavity 21 of the sleeve 20. In some embodiments, the ball head 30 is provided with a connecting portion 90 extending to the outside of the sleeve 20, so that the ball head 30 is close to the base 10. After the ball head 20 is abutted against the threaded column 11, the locking knob 50 is sleeved on the outer wall of the sleeve 20 from top to bottom, and the convex edge 22 on the outer periphery of the lower end of the sleeve 20 cooperates with the locking knob 50, and then the locking knob 50 is threadedly connected to the threaded column 11. In the process of continuously screwing down, the sleeve 20 will be driven to continuously apply downward pressure to the ball head 30 until the ball head 30 is tightly abutted between the sleeve 20 and the base 10 (threaded column 11), thereby limiting the angle of the ball head 30. It should be noted that It is clear that by arranging a limit assembly 40 between the upper end surface of the threaded column 11 and the lower end surface of the sleeve 20, the relative rotation between the sleeve 20 and the base 10 can be limited, that is, the sleeve 20 can be prevented from slipping relative to the base 10; when in use, the device is installed on the connecting part 90, and after the locking knob 50 is rotated upward to unlock the ball head 30, the ball head 30 can rotate in the spherical cavity 21, and cooperate with the pitch adjustment hole 23 on the outer wall of the sleeve 20 that is connected to the spherical cavity 21, so as to realize universal angle adjustment in the horizontal direction; the advantage of the utility model is that: the above structure can simplify the structure of the bracket, improve the efficiency of assembly, and solve the problem that the locking knob of the bracket is easy to slide and difficult to lock, and has very good practicality.

[0034] In some embodiments, a supporting seat 60 is provided in the middle of the upper end surface of the threaded column 11, and the upper end surface of the supporting seat 60 has an arc groove 61 adapted to the ball head 30; this setting enables the ball head 30 to rotate more smoothly in the spherical cavity 21.

[0035] In some embodiments, the limit assembly 40 includes a plurality of first limit teeth 41 arranged on the upper end surface of the threaded column 11 and a plurality of second limit teeth 42 arranged on the lower end surface of the sleeve 20, and the second limit teeth 42 are engaged with the first limit teeth 41; when the locking knob 50 drives the sleeve 20 to push the ball head 30 close to the base 10, the second limit teeth 42 will engage with the first limit teeth 41, thereby limiting the relative rotation between the sleeve 20 and the base 10, greatly improving the situation where the bracket slips and is difficult to lock.

[0036] In some embodiments, a plurality of protrusions 70 are provided on the inner wall of the sleeve 20 to abut against the ball head 30; by providing the protrusions 70 and designing the materials of the protrusions 70 and the ball head 30, the friction between the sleeve 20 and the ball head 30 can be increased, thereby improving the locking degree of the sleeve 20 and the base 10 on the ball head 30.

[0037] In some embodiments, a plurality of protrusions 80 are provided on the outer wall of the locking knob 50 ; the protrusions 80 are provided to facilitate the user to rotate the locking knob 50 , thereby improving the convenience of locking and unlocking.

[0038] In some embodiments, a plurality of mounting holes 12 are provided on the base 10 ; the base 10 is mounted on the mounting position by engaging bolts with the mounting holes 12 .

[0039] In some embodiments, the base 10 , the sleeve 20 , the ball head 30 , and the locking knob 50 are made of plastic; this configuration can reduce the manufacturing cost of the bracket.

[0040] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
