[0032] In this embodiment, when it is necessary to collect evidence at the scene, it is only necessary to select appropriate module components according to the actual situation at the scene. By setting the first module component, the second module component, the third module component and the fourth module component, the multifunctionality of the device body 1 can be effectively improved, thereby effectively improving the evidence collection efficiency at the scene and improving the overall practicality of the device. When the device body 1 is not needed, the camera part of the device body 1 can be conveniently and effectively protected by the protective component, thereby effectively extending the service life of the device body 1 and further improving the overall on-site adaptability of the device.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the first functional module component includes an ultrawide spectrum intelligent exploration module 3 located on the rear side of the device body 1. The ultrawide spectrum intelligent exploration module 3 adopts a scientific research-grade spectral image sensor with a sensing range of 160-1100nm.

It can perform optical search, microscopic imaging, analysis and differentiation, precise positioning and fine extraction of trace DNA evidence, and is suitable for searching and extracting exfoliated cells on objects.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the fourth functional module component includes the on-site light distribution evidence collection module 6 located directly below the exfoliated cell search and display module 5. The on-site light distribution evidence collection module 6 adopts a built-in micro directional reflection device and integrated light source micro design, which can display non-permeable or semi-permeable smooth objects and difficult fingerprints on irregular surfaces in seconds. It supports high-definition non-destructive shooting and extraction, and is suitable for smooth non-permeable objects, such as: glass, screen, ID card, bank card, CD, etc.

[0037] In one embodiment, such as Figures 1-3 As shown, multiple connecting plates 7 are fixedly connected to the rear surfaces of the ultrawide spectrum intelligent exploration module 3, the visualization laser targeting module 4, the exfoliated cell search and display module 5, and the on-site light distribution evidence collection module 6. Insert blocks 8 are fixedly connected to the front surfaces of the multiple connecting plates 7. Guide grooves for the insertion blocks 8 to move are provided on the rear surfaces of the multiple mounting frames 2. Movable grooves for the ultrawide spectrum intelligent exploration module 3, the visualization laser targeting module 4, the exfoliated cell search and display module 5, and the on-site light distribution evidence collection module 6 are provided on the rear surface of the device body 1. When the entire device needs to be used, it is only necessary to first determine the appropriate location based on the on-site conditions. In practice, the following modules can be selected: ultra-wide spectrum intelligent exploration module 3, visualization laser targeting module 4, exfoliated cell search and display module 5, or on-site light distribution evidence collection module 6. After the module is selected, it is inserted into the movable slot on the rear surface of the device body 1. At this time, the module will drive the connecting plate 7 and the plug 8 to move synchronously. When the plug 8 is inserted into the inside of the mounting frame 2, the mounting frame 2 and the plug 8 are fixed. At this time, different modules can be installed between the device body 1, which facilitates the use of the device by the staff and effectively improves the overall multifunctionality of the device.

[0038] In one embodiment, such as Figure 2 and Figure 4 As shown, a fixing plate 11 is fixedly connected to both the upper and lower surfaces of the device body 1. An inner plate 12 is fixedly connected to the middle of the inner wall of the fixing plate 11. Slide rods 13 are symmetrically arranged on the left and right surfaces of the inner plate 12. The other ends of multiple slide rods 13 are fixedly connected to the inner wall of the fixing plate 11. A sliding plate 14 is slidably connected to the outside of every two slide rods 13. A return spring 15 is sleeved on the outside of multiple slide rods 13. Multiple return springs 15 abut against the sliding plate 14 and the inner plate 12. A lever 17 is fixedly connected to the outside of the sliding plate 14. A groove for the lever 17 to move is opened on the outside of the fixing plate 11. A plug rod 16 is fixedly connected to one side of multiple sliding plates 14. The interiors of multiple mounting frames 2 and plug blocks 8 are provided with grooves for the plug rod 16 to move. When it is necessary to fix the plug 8 to the mounting frame 2, simply press the lever 17. The lever 17 will drive the slide plate 14 to move synchronously outside the slide rod 13. During the movement of the slide plate 14, the return spring 15 will be squeezed. The slide plate 14 will also drive the plug rod 16 to move synchronously. Then, insert the plug 8 into the mounting frame 2 and release the lever 17. The return spring 15 will then return to its original position, driving the slide plate 14 to move synchronously to its original position. The slide plate 14 will then drive the plug rod 16 to move synchronously to its original position. When the plug rod 16 is inserted into the slot inside the plug 8, the plug 8 can be fixed to the mounting frame 2. At this time, different modules can be fixedly assembled with the equipment body 1.

[0039] In one embodiment, such as Figure 3 and Figure 5 As shown, the protective assembly includes a connecting frame 18 fixedly connected to the left side surface of the equipment body 1. A fixing rod 19 is fixedly connected inside the connecting frame 18, and a spiral spring 20 is fixedly connected to the outside of the fixing rod 19. A rotating sleeve 21 is fixedly connected to the other end of the spiral spring 20. A protective frame 9 is fixedly connected to the outside of the rotating sleeve 21 via an L-shaped plate 22. A sealing ring 10 is adhered to the right side surface of the protective frame 9. When it is necessary to assemble the module with the equipment body 1, simply pull the protective frame 9 first. The protective frame 9 will then move the L-shaped plate 22 synchronously, and the L-shaped plate 22 will then move the rotating sleeve 21 synchronously. Rotating the sleeve 21 stretches the spiral spring 20, opening the protective frame 9 and facilitating the connection and installation of different modules with the equipment body 1. When the equipment body 1 is no longer needed, the module is removed, the spiral spring 20 resets, and the sleeve 21 rotates synchronously. The sleeve 21 then moves the L-shaped plate 22 and the protective frame 9 back to their original positions. When the protective frame 9 completely covers the outside of the equipment body 1, it protects the camera part of the equipment body 1, effectively extending the service life of the equipment body 1.

[0040] The above embodiments disclose a handheld bio-evidence laser display device. When on-site evidence collection is required, appropriate module components can be selected according to the actual situation. By setting up the ultra-wide spectrum intelligent investigation module 3, the visualization laser targeting module 4, the exfoliated cell search and display module 5, and the on-site light distribution evidence collection module 6, the multifunctionality of the device body 1 can be effectively improved, thereby improving the efficiency of on-site evidence collection and enhancing the overall practicality of the device. When the device body 1 is not in use, the camera part of the device body 1 can be conveniently and effectively protected by the protective frame 9, thereby effectively extending the service life of the device body 1 and further improving the overall on-site adaptability of the device.
