[0027] The limiting mechanism 3 includes a first right-angle block 31, the first right-angle block 31 is fixedly connected to the top of the pressure gauge body 1, a fixed box 32 is fixedly connected to the right side of the first right-angle block 31, a spring 33 is fixedly connected to the inner wall of the fixed box 32, one end of the spring 33 away from the fixed box 32 is fixedly connected to a sliding block 34, a connecting plate 37 is fixedly connected to the front of the sliding block 34, a pull shaft 36 is fixedly connected to the right side of the sliding block 34, a pull plate 35 is fixedly connected to the right end of the pull shaft 36, an internal spline 39 is fixedly connected to the front of the connecting plate 37, and an external spline 38 is arranged on the outside of the rotating mechanism 4.

[0028] Furthermore, an opening is formed in the front of the fixed box 32, and the connecting plate 37 penetrates through the opening and moves, so that the connecting plate 37 can move through the opening.

[0029] Further, the sliding block 34 is slidably connected to the inner wall of the fixed box 32, and the spring 33 is sleeved on the outer wall of the pull shaft 36, so that the sliding block 34 can stably move to compress the spring 33.

[0030] Further, a through hole is provided on the right side of the fixed box 32, and the pull shaft 36 penetrates through the provided through hole and moves, so that the pull shaft 36 can move through the through hole.

[0031] Embodiment 2

[0032] Refer to Figures 1 to 4 , and on the basis of Embodiment 1, it is further obtained that the rotating mechanism 4 includes a right-angle block two 41, the right-angle block two 41 is fixedly connected to the top of the pressure gauge body 1, a rotating shaft 42 is rotatably connected inside the right-angle block two 41, and a connecting block 43 is fixedly connected to the outer wall of the rotating shaft 42, which is convenient for flipping the transparent protective cover 2.

[0033] Further, the connecting block 43 is fixedly connected to the top of the transparent protective cover 2, and the rotating shaft 42 is rotatably connected inside the right-angle block one 31 to stably support the rotating shaft 42.
