[0027] The positioning mechanism 5 includes a fixed box 51, which is arranged on one side of the mounting mechanism 4. The inner wall of the fixed box 51 is rotatably connected to a threaded rod 52, and the outer wall of the threaded rod 52 is threadedly connected to a Z-shaped plate 53. A rectangular plate 54 is fixedly connected to one side of the Z-shaped plate 53, and an insert block 55 is fixedly connected to one side of the rectangular plate 54. A fixed block 56 is fixedly connected to the outer wall of the connecting pipe 2, and a slot 57 is opened inside the fixed block 56.

[0028] Further, such as Figure 2 As shown, the threaded rod 52 penetrates the front side of the fixed box 51 and rotates, and a handle is fixedly connected to the outer wall of the front end of the threaded rod 52, so that the threaded rod 52 can be driven by the handle to rotate stably.

[0029] Furthermore, the outer shape of the Z-shaped plate 53 matches the shape of the inner wall of the fixed box 51 , and the Z-shaped plate 53 is slidably connected to the inner wall of the fixed box 51 , so that the Z-shaped plate 53 can move stably.

[0030] Furthermore, the right side of the fixed box 51 is opened, and the Z-shaped plate 53 passes through the right side of the fixed box 51, so that the Z-shaped plate 53 can move through the opening.

[0031] Furthermore, the shape of the inner wall of the slot 57 matches the outer shape of the plug block 55, and the plug block 55 is movably connected to the inner wall of the slot 57, which provides stable support for the plug block 55; the movable connection here refers to a detachable connection structure, which is easy to assemble and disassemble.

[0032] Embodiment 2:

[0033] See also Figures 1 to 4 On the basis of the first embodiment, the mounting mechanism 4 further comprises a fixing groove 41, the fixing groove 41 is fixedly connected to the outer wall of the pressure gauge 3, a protrusion 42 is slidably connected to the inner wall of the fixing groove 41, a fixing arm 43 is fixedly connected to the bottom of the protrusion 42, and a bolt 44 is arranged on the top of the protrusion 42, so as to facilitate the installation and connection of the fixing box 51.
