The connection strength of the mounting brackets 8 ensures its stable structure, easy installation and adjustment.

The design of the positioning wheel 81 needs to consider its smooth rolling, wear resistance and the contact mode with the detection mechanism 5. The positioning plate 82 is on the outer side wall of the first housing 51 and the positioning plate 82 is installed by bolts. The positioning plate 82 cooperates with the positioning wheel 81. When the detection mechanism 5 moves to the preset position, the positioning plate 82 will contact the positioning wheel 81, thereby restricting the further movement of the detection mechanism 5. The design of the positioning plate 82 needs to ensure its accurate position, firm fixation and can generate sufficient resistance when contacting the positioning wheel 81 to prevent the detection mechanism 5 from continuing to move.

[0040] It should be noted that the distance between the two mounting brackets 8 is adjustable; this structure allows users to adjust the running stroke of the detection mechanism 5 according to actual needs. By adjusting the position of the mounting brackets 8 or using other adjustment mechanisms, the distance between the two positioning wheels 81 can be easily changed to adapt to different detection requirements.

[0045] When the X-ray generating device 56 is working, a large amount of heat will be generated; this heat is first absorbed by the spiral tube 74 because the spiral tube 74 tightly surrounds the outer wall of the X-ray generating device 56; as the coolant in the spiral tube 74 flows, the absorbed heat is transferred to the coolant; the coolant circulates inside the spiral tube 74, continuously absorbing and carrying away the heat; the coolant carrying the heat then flows out of the first outer shell 51 through the fourth cooling tube 76 and enters the interior of the frame 1; inside the frame 1, the coolant may undergo further heat dissipation treatment to dissipate the heat into the air; the coolant after heat dissipation treatment returns to the interior of the first outer shell 51 through the fourth cooling tube 76 again and re-enters the spiral tube 74 for the next round of cooling cycle;
