[0047] Working principle: When radiotherapy is to be performed on a patient, first let the patient lie on the bed board 19, and then start the drive motor 21. At this time, the output shaft of the drive motor 21 drives the single-threaded lead screw 22 to rotate. The rotation of the single-threaded lead screw 22 drives the moving plate 12 to move downward. The downward movement of the moving plate 12 drives the radiotherapy instrument 14 to move downward, and the downward movement of the radiotherapy instrument 14 facilitates radiotherapy on the patient. Moreover, the downward movement of the moving plate 12 drives the protective cylinder 15 to move downward, which facilitates covering the patient's chest. In summary, by adopting the above solution, it is convenient to cover the patient's chest during radiotherapy on the patient.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
