[0041] Working principle: before using the explosive detection device, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 Figure 11 ​As shown, first, the detection instrument body 101 is started by the start button 104 at the bottom of the handheld handle 103, so that the detection of explosives can be realized. When the detection instrument body 101 is started, the article is placed inside the second clamping plate 122, and the detection probe 110 at the end of the detection support 109 is contacted by the article, so that the detection of explosives can be realized. When the radiation protection detection needs to be carried out by the test support, the container needs to be clamped and fixed. By inwardly extruding the container, the container extrudes the detection probe 110 and the detection support 109, and the detection support 109 extrudes the connecting spring 108. When the second sliding block 118 at the end of the pushing support 117 is slidably connected with the first sliding block 113, the first sliding block 113 drives the connecting column 115 and the pushing ball 116 to extrude the first spring 114 under the action of the connecting sliding sleeve 112, and the pushing ball 116 extrudes the end of the first clamping plate 120. Under the action of the elastic force of the clamping spring 126 inside the first rotating support 119 and the second rotating support 123, the relative stability of the first clamping plate 120 and the second clamping plate 122 can be realized. When the container extrudes the second rotating support 123, the rotation of the second clamping plate 122 can be realized, so that the clamping and fixing of the container can be realized.

[0042] Secondly, by the relative rotation of the first clamping plate 120 and the second clamping plate 122, containers with different diameters can be clamped, so as to adapt to more extensive containers and enable the detection of explosives in different occasions. When the container is pulled outward, the container can be taken out from the inside of the second clamping plate 122, so as to facilitate the detection of explosives. By the elastic force of the positioning spring 132 inside the placing seat 128, the positioning sliding sleeve 131 is relatively slid outside the positioning sliding rod 130, and the detection instrument body 101 is fixed by the positioning block 133, so as to facilitate the placement of the detection instrument body 101.

[0043] Finally, the radiation generated during detection can be shielded by the radiation protection cover body 201, so as to achieve the effect of protection. At the same time, the lifting motor 204 drives the chain wheel transmission assembly 205 and the lifting threaded rod 206 to rotate, so that the lifting threaded sleeve 207 drives the lifting baffle 208 to move up and down, and the radiation protection cover body 201 can be opened, so as to facilitate the taking and placing of the container. By the elastic force of the locking spring 212 inside the locking support 209, the locking clamping plate 214 and the locking sliding plate 213 are relatively slid by pulling the unlocking handle 215. Under the elastic force of the locking spring 212, the placing seat 128 is clamped and fixed by the locking clamping plate 214, so as to facilitate the fixation of the detection instrument and improve the stability during detection.
