[0028] The protective sleeve includes a first semi-cylinder 201 and a second semi-cylinder 205 which are symmetrically arranged; on the opposite sides of the first semi-cylinder 201 and the second semi-cylinder 205, there are respectively arranged a connecting and fixing groove 203 and an adapter plate 204 which are mutually matched, and the adapter plate 204 of the second semi-cylinder 205 is inserted into the connecting and fixing groove 203 of the first semi-cylinder 204, so that the first semi-cylinder 201 can be closely attached to the second semi-cylinder 205; on the sides of the first semi-cylinder 201 and the second semi-cylinder 205, there are respectively arranged a first positioning piece 202 and a second positioning piece 206;

[0029] The connecting component 3 includes a connecting sleeve 301; on both end faces of the connecting sleeve 301, there are provided limiting grooves 302; inside the connecting sleeve 301, there are arranged movable rack components 303 in a staggered manner up and down;

[0030] One end of the pipe body main body 101 close to the first fixed rack 103 passes through the protective sleeve and extends into the connecting component 3, and the first fixed rack 103 meshes with the movable rack component 303. The first fixed rack 103 and the second fixed rack 104 are respectively meshed with the movable rack component 303 in a movable manner, so that the boiler pressure vessel inspection gauge is fixed by rack meshing; the first positioning piece 202 and the second positioning piece 206 of the protective sleeve are respectively inserted into the limiting grooves 302 at the ends of the connecting sleeve 301 and are fixedly connected to the connecting sleeve 301, so that the protective sleeve can be closely attached to and fixed with the connecting component 3.
