[0024] The fixing block 18 is embedded in the limiting card slot 10, the fixing block 18 and the limiting card slot 10 cooperate with each other, the outside of the threaded rod 21 is provided with an external thread, the inside of the threaded groove 20 is provided with an internal thread that cooperates with the external thread, and the threaded rod 21 and the threaded groove 20 are threadedly connected;

[0025] Specifically, Figure 1 and Figure 3 As shown, when the detection phantom body 8 needs to be installed on the top of the right side of the phantom box body 1, the left side of the mounting frame 9 is clamped on the right side of the top of the phantom box body 1. During the placement process, the fixing block 18 and the limiting slot 10 are aligned. After alignment, the turning handle 22 is turned, and the turning handle 22 drives the threaded rod 21 to rotate inside the thread groove 20. Since the threaded rod 21 and the thread groove 20 cooperate with each other, turning the turning handle 22 can make the threaded rod 21 drive the limiting plate 19 and the fixing block 18 to move, so that the fixing block 18 can be embedded in the limiting slot 10 to limit and fix the mounting frame 9, thereby preventing the detection phantom body 8 from accidentally moving when the mounting frame 9 is working.

[0026] Embodiment 2: The four corners at the bottom of the mold box body 1 are fixedly connected with support blocks 11, the bottom of the support block 11 is fixedly connected with a suction cup 2, the inner side wall of the mold box body 1 is provided with a first protective sponge 3, the top of the mold box cover 4 is provided with a second protective sponge 5, the top of the mold box cover 4 is fixedly connected with a handle 12, and the outside of the handle 12 is provided with a protective cover 13;

[0027] The right sides of both ends of the mounting frame 9 are fixedly connected with a fixing plate 23, and the fixing plate 23 and both ends of the mounting plate 17 are respectively provided with fixing grooves 25, and the fixing grooves 25 are provided with fixing bolts 24.

The handle 12 and the protective cover 13 at the top of the mold box cover 4 can facilitate the user to lift the mold box body 1.

[0031] Working principle: When in use, the utility model clamps the left side of the mounting frame 9 on the right side of the top of the model box main body 1, and aligns the fixing block 18 with the limiting slot 10 during the placement process. After alignment, turn the turning handle 22, and the turning handle 22 drives the threaded rod 21 to rotate inside the threaded slot 20. Turning the turning handle 22 can make the threaded rod 21 drive the limiting plate 19 and the fixing block 18 to move, so that the fixing block 18 can be embedded in the limiting slot 10 to limit and fix the mounting frame 9, so as to prevent the mounting frame 9 from accidentally moving during the operation of the detection model body 8. After fixing the mounting frame 9, the model box main body 1 is placed in a suitable position, and then the position of the detection model body 8 is adjusted so that the selected isocenter coincides with the accelerator isocenter, and then the model box main body 1 is limited by the suction cup 2. After the detection is completed, reverse the turning handle 22 to fix the mounting frame 9.
