[0027] See also Figure 1 、 Figure 2 、 Figure 3 An embodiment of the present invention provides an adjustable mounting bracket, including a base 100, a guide rail assembly 200 and a mounting base 300. The mounting base 300 is arranged on the guide rail assembly 200, and the mounting base 300 can adjust its position along the guide rail direction through the guide rail assembly 200. The guide rail assembly 200 is supported on the base 100 through a ball joint structure 400. At least three tensioning components are provided between the guide rail assembly 200 and the base 100, one end of the tensioning component is connected to the base 100, and the other end of the tensioning component is connected to the guide rail assembly 200.

Furthermore, the adjustment structure is simple, easy to adjust, and highly efficient.
[0029] In some embodiments, see Figure 1 、 Figure 3The base 100 extends from a first edge 101 to a second edge 102 along the width direction. The tensioning components include a first tensioning component 601, a second tensioning component 602, a third tensioning component 603, and a fourth tensioning component 604.

Extending the stroke of the first tensioning component 601 and the third tensioning component 603 and the fourth tensioning component 604 and shortening the stroke of the second tensioning component 602 and the fourth tensioning component 604 can achieve fine rotation adjustment around the y-axis, and vice versa.
[0030] Further, see Figure 1-Figure 3 The base 100 has a first bottom beam 103 and a second bottom beam 104 extending from the first edge 101 to the second edge 102.

The vertical guide rail 202 is equipped with a vertical screw rod 207 that drives the vertical slider 204. The vertical screw rod 207 is connected to a second adjustment handle 208. The second adjustment handle 208 can be used to quickly adjust the position of the vertical slider 204 on the vertical guide rail 202. Slow rotation can achieve fine adjustment in the z-direction.
[0035] In some embodiments, see Figure 3 、 Figure 4 The mounting base 300 includes a first mounting plate 301 and a second mounting plate 302, which are connected by a hinge. The first mounting plate 301 is connected to the vertical slider 204, and the second mounting plate 302 defines a vertical rotation axis via the hinge. In this embodiment, the mounting base 300 includes the first mounting plate 301 and the second mounting plate 302, and the second mounting plate 302 defines a vertical rotation axis via the hinge.

By rotating the turnbuckle 305, the length of the turnbuckle 305 assembly can be quickly adjusted, thereby changing the angle between the first mounting plate 301 and the second mounting plate 302. In this embodiment, the turnbuckle 305 assembly uses threaded engagement to achieve stroke adjustment, enabling fine-tuning.
[0037] In some embodiments, see Figure 3 The ball joint structure 400 includes a ball head 401 arranged on the top of the base 100 and a ball head seat 402 arranged on the guide rail assembly 200. The ball head seat 402 cooperates with the ball head 401 and further cooperates with the surrounding tensioning components to achieve different rotation adjustments of the guide rail assembly 200.
