[0024] See also Figure 1 -6. A rotary hydraulic joint capable of connecting at multiple angles, comprising a fixed joint portion 100, a rotary joint portion 200, and a fixed portion 300. The rotary joint portion 200 has an L-shaped structure, a threaded male connector 101 is provided at one end of the fixed joint portion 100, and a rotary mounting portion 102 is provided at the other end of the fixed joint portion 100.

[0025] One end of the rotary joint portion 200 is provided with a rotary connection portion 201, which is rotatably connected to the rotary mounting portion 102, and the other end of the rotary joint portion 200 is provided with a threaded female connector 202;

[0026] Specifically, the inner wall of the rotating mounting portion 102 is fixedly connected to a rotating connecting platform 103, which is provided with a rotating groove 104. Both sides of the rotating groove 104 are provided with sealing grooves. The rotating connecting portion 201 is fixedly connected to a ring platform 203, and both sides of the ring platform 203 are fixedly connected to a sealing ring 204. The ring platform 203 is located in the rotating groove 104, and the sealing ring 204 cooperates with the sealing groove. In this way, a rotating connection between the fixed joint portion 100 and the rotating joint portion 200 can be achieved, and a sealing effect is achieved through the sealing ring 204 to prevent hydraulic leakage.

[0027] Furthermore, the fixed joint portion 100 is provided with two sets of fixed parts 300, and the fixed part 300 includes a clamping plate 301, a spring 302, a sliding column 303 and an operating part 304. The clamping plate 301 is provided inside the rotating mounting portion 102, and the sliding column 303 is fixedly connected to the clamping plate 301. The sliding column 303 passes through the rotating mounting portion 102, and the area of ​​the sliding column 303 located outside is fixedly connected to a pressure plate 305. The sliding column 303 is sleeved with a spring 302, one end of the spring 302 is fixedly connected to the rotating mounting portion 102, and the other end is fixedly connected to the pressure plate 305. The sliding column 303 matches the operating part 304;

[0028] The operating portion 304 includes a lower pressing arm 306, a traction column 307, and a lever fulcrum frame 308. The top of the sliding column 303 is fixedly connected to the traction column 307, and the traction column 307 is fixedly connected to the sliding shaft 309. The rotatable mounting portion 102 is fixedly connected to the lever fulcrum frame 308, and the lever fulcrum frame 308 is rotatably connected to the lower pressing arm 306.
