At this time, the positioning block 802 can be disengaged from the inside of the positioning groove 805, and the tooling plate 9 can be disassembled. Conversely, the tooling plate 9 can be installed to install tooling plates 9 of different specifications, so that covers of different specifications can be fitted with the tooling plates 9, thereby increasing the efficiency of gas detection.
