[0026] The shock absorbing structure 7 includes three telescopic rods 8, the two ends of the three telescopic rods 8 are respectively connected to the bottom of the cover 2 and the top of the device body 5, three springs 9 are arranged between the bottom of the cover 2 and the top of the device body 5, both sides of the device body 5 are respectively connected to the rear of the two baffles 11 through a plurality of telescopic rods 10, and a plurality of springs 12 are respectively arranged between the rear of the two baffles 11 and the two sides of the device body 5.
[0027] After the device body 5 is installed inside the shell 1 and the cover 2 is installed, the spring 1 9 acts on the device body 5 to move the telescopic rod 1 8 downward toward the inner bottom surface of the inner side of the shell 1 until the bottom of the device body 5 fits the outside of the connecting tube 16 outside the U-shaped tube 17 in a vertical state. At this time, the spring 2 12 acts on the baffle 11 to press the telescopic rod 2 10 toward the inner ends of the shell 1, and finally the baffle 11 is tightly attached to the inner ends of the shell 1, which supports the device body 5, strengthens the supporting force of the device body 5, and reduces the impact of vibration.
[0028] In this embodiment, the three springs 1 9 are respectively adapted to match the positions of the three telescopic rods 1 8 , and the plurality of springs 2 12 are respectively adapted to match the positions of the plurality of telescopic rods 2 10 .
[0029] Spring 1 9 and spring 2 12 play an elastic supporting role for the device body 5 .
[0030] In this embodiment, an optical path device 3 and two infrared LED lamps 4 are respectively disposed at one end of the housing 1 , and a CCD camera 6 is disposed at the bottom of the device body 5 .
[0031] The infrared LED light 4 cooperates with the CCD camera 6 to make the position of the blood vessels visible.
[0032] In this embodiment, a reserved hole is opened at the bottom of the housing 1 , and the CCD camera 6 is adaptively matched with the housing 1 .
[0033] The CCD camera 6 can pass through the reserved hole of the housing 1 when needed.
[0034] In this embodiment, an adjustment structure 13 is provided on the inner bottom surface of the outer shell 1, and the adjustment structure 13 includes a screw rod 14, which is rotatably arranged inside the outer shell 1 near the inner bottom surface, and two sliders 15 and a slide plate 19 are slidably arranged outside the screw rod 14, and the outsides of the two sliders 15 are rotatably connected with connecting tubes 16, one end of the two connecting tubes 16 is rotatably arranged on the outside of two U-shaped tubes 17, and the bottoms of the two U-shaped tubes 17 are rotatably arranged on the outside of two rotating shafts 18.
[0035] When the CCD camera 6 needs to be used, the screw rod 14 is rotated so that the two sliders 15 and the slide plate 19 slide outside the screw rod 14 in the opposite direction of the CCD camera 6. During the process, the slider 15 rotates outside the rotating shaft 18 with the U-shaped tube 17 through the connecting tube 16. When the slider 15 slides to a suitable position, the slide plate 19 exposes the reserved hole at the bottom of the outer shell 1, and the U-shaped tube 17 tilts in the opposite direction of the CCD camera 6. At this time, the device body 5 continues to move downward along with the position of the connecting tube 16 under the action of the spring 9, and finally exposes the CCD camera 6 from the reserved hole of the outer shell 1.
[0036] In this embodiment, the two rotating shafts 18 are fixedly arranged on the inner bottom surface of the housing 1, the slider 15 and the slide plate 19 are both adaptively matched with the screw rod 14, and the slide plate 19 is adaptively matched with the housing 1, the device body 5, and the CCD camera 6.

[0040] It should be noted that the utility model is a near-infrared light tracking instrument. When in use, it can be placed in a place where it needs to work to achieve working conditions;
[0041] During the process, the device body 5 is installed inside the housing 1, and after the cover 2 is installed, the spring 1 9 acts on the device body 5 to move the telescopic rod 1 8 downward toward the inner bottom surface of the housing 1, until the bottom of the device body 5 fits the outside of the connecting tube 16 outside the U-shaped tube 17 in the vertical state. At this time, the spring 2 12 acts on the baffle 11 to press the telescopic rod 2 10 toward the inner ends of the housing 1, and finally the baffle 11 is closely attached to the inner ends of the housing 1, which supports the device body 5, strengthens the supporting force of the device body 5, and reduces the impact of vibration;
[0042] During the process, when the CCD camera 6 needs to be used, the screw rod 14 is rotated so that the two sliders 15 and the slide plate 19 slide outside the screw rod 14 in the opposite direction of the CCD camera 6. During the process, the slider 15 rotates outside the rotating shaft 18 with the U-shaped tube 17 through the connecting tube 16. When the slider 15 slides to the appropriate position, the slide plate 19 exposes the reserved hole at the bottom of the outer shell 1, and the U-shaped tube 17 tilts in the opposite direction of the CCD camera 6.
