[0049] In a further embodiment of the present invention, a threaded hole is drilled on the transition ring in the brazing assembly 9, the thermocouple 11 and the transition ring are connected together by bolts, and two sections of shielding boxes 10 are arranged around the thermocouple 11, and the shielding box 10 is provided with a lead groove, one end of the fixing rod 7 is connected to the brazing assembly 9 by screws, and the other end of the fixing rod 7 is connected to the shielding box 10 by bolts and nuts.

[0050] In a further embodiment of the present invention, the thermocouple 11 is connected to an accelerator control device 13 and is equipped with a display device 14.

[0051] In a further embodiment of the present invention, a thermocouple 11 and a control device 13 thereof are installed on the beam scraper by threads. If the beam in the accelerating tube is offset, we can know the position of the beam offset according to the temperature difference display of the thermocouple 11, and timely adjust the beam scraper automatically or manually to ensure that the beam passes through the center of the accelerating tube, effectively reducing the downtime for maintenance and improving work efficiency. In addition, the present invention is easy to install, simple to disassemble, and reliable to fix.
