Referring to fig. 7 and 8, embodiment 2 is different from embodiment 1 in that a stopper 33 and a stopper groove 34 are added, the stopper 33 is installed on one side of the support hole 13 near the support portion 12, and the stopper groove 34 is opened on one side of the support portion 12 near the stopper groove 34 for embedding the stopper 33. Because the high-pressure gas is the weakest in the time of towards indicating device 5, because the center of observation portion 8 is the weakest, and high-pressure gas is gone out from the center of observation portion 8 easily, leads to the supporting part 12 to shrink to observation portion 8 because of huge impact force this moment easily, and in this application scheme, when embedding in spacing groove 34 through stopper 33, carry out spacingly to supporting part 12, reduce the probability that supporting part 12 takes place the displacement, also improve the bearing capacity of supporting part 12 to arc pressure simultaneously.
