The limit ring 3 can be pushed onto the pressure gauge main body 10 by holding the handle 1, so that the slot 9 moves to the alignment position of the insertion block 6. Then release the pull block 7. Under the push of the spring 20, drive the insertion block 6 to reset through the pull rod 18, so that the insertion block 6 is inserted into the slot 9 to fix the position of the limit ring 3. Thus, the protective cover 2 is installed.
[0022] A glass lens 12 is arranged at the front end of the pressure gauge main body 10, and a rubber gasket 13 is arranged at the edge of the glass lens 12. When in use, the pressure gauge main body 10 can be observed through the glass lens 12, and the rubber gasket 13 can protect the edge of the glass lens 12 to avoid hurting hands.
