The sliders 206 are fixedly connected to the installation box 301. The installation box 301 is suitable for moving along the linear direction of the slide rails 205 with the rotation of the first motor 202, so as to be suitable for approaching or moving away from the detection barrel 104;

[0033] A connecting rod 302 is installed on one side of the installation box 301 close to the placement plate 101, a second motor 303 is fixedly installed on one end of the connecting rod 302 close to the placement plate 101, a chuck 304 is installed at the output end of the second motor 303, the chuck 304 has four groups of extended ends, and four groups of first cylinders (not shown in the figure) are installed on the chuck 304, the output end of the first cylinder is connected to the extended end, so as to make the four groups of extended ends approach or move away from each other, and further to clamp and fix the inner tube;
