This design solves the problem that the prior art makes the disassembly and assembly of the pressure differential gauge on the outside of the installation bracket more troublesome and time-consuming.

[0029] See also Figure 4 and Figure 5The limit assembly 5 includes a limit block 51, which is fixedly connected to the inner wall of the side groove 13.
