The universal joint can connect two intersecting shafts and allow them to rotate relative to each other within a certain angle range, so as to transmit power between shafts at different angles and positions.

[0003] However, the existing universal joint adjusting structures are all realized by friction, with poor effects. In the case of strong vibration scenarios, the adjusting effect is directly lost. Moreover, the adjusting angle of the universal joint is limited, and the approximate adjusting range is 0 - 90°. In addition, there is a problem of weight limitation, and the adjusting effect is lost when the weight exceeds a certain value. Therefore, it is necessary to design a universal joint adjusting structure with a wide adjusting range. Summary of the Utility Model

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. In the present utility model, by setting the first inner gear disc, the second outer gear, the second inner gear disc and the first outer gear, when using the universal joint adjustment structure, when it is necessary to rotate and adjust the first bracket, the staff loosens the second nut, and then pulls up the first bracket. At this time, the second outer gear and the second inner gear disc are disengaged. Then, the staff rotates the first bracket as needed to adjust the first bracket to a suitable position. When the adjustment is completed, the second outer gear is placed inside the second inner gear disc to form a meshing connection between the second outer gear and the second inner gear disc, and the second nut is tightened on the second bolt.

At the same time, it can effectively avoid the influence brought by strong vibration scenarios and can be used safely and reliably in any vibration scenario. Therefore, it is convenient to use and has strong reliability. BRIEF DESCRIPTION OF THE DRAWINGS
