[0040] When it is necessary to adjust the clamping angle of the fixed plate 35, the motor A5 is started by controlling the switch 4. The operation of the motor A5 drives the gear A312 connected to the top thereof to rotate. The rotation of the gear A312 drives the gear ring 313 of the inner core at one end thereof to rotate. The rotation of the gear ring 313 drives the mounting frame 311 fixed to the outer wall to rotate at the top of the mounting plate 314.

The movement of the pushing seat 343 drives the fixed plate 35 connected to the top thereof to move. The movement of the pushing seat 343 drives the gear plate 344 connected to the outer wall thereof to move. The movement of the gear plate 344 drives the gear B345 meshing with the outer wall to rotate. The rotation of wheel B345 drives the other tooth plate 344 engaged with its outer wall to move, and the movement of the other tooth plate 344 drives the other pushing seat 343 to move on the slide rail 346, and the movement of the other pushing seat 343 drives the other fixed plate 35 to move. The two fixed plates 35 move inward to fix the SCR honeycomb catalyst. When the SCR honeycomb catalyst is clamped, it is rotated and sampled by the sampling drill 10. When sampling, the motor B64 can be started by the control switch 4. The operation of the motor B64 drives the dust extraction fan 63 connected to its output end to operate. The dust extraction fan 63 operates, with the help of the dust extraction hole 62 opened on the outer wall of the dust extraction box 61 and the dust extraction pipe 8 provided at the bottom end of the dust extraction box 61, and dust is extracted at the sampling point. The dust and other pollutants on the surface of the catalyst can be extracted.
