[0030] In this embodiment, the spectral gun head 10 is electrically connected to the Raman detector for use. When performing Raman detection on an object, the object to be detected is placed on the stage 1, and the Raman detector performs Raman spectrum detection on the object through the spectral gun head 10. When it is necessary to perform Raman detection on the object outdoors or in an environment where the light source cannot be turned off, the object to be detected is placed on the stage 1 by pulling the two light-shielding dark chamber shells 4, and then the two light-shielding dark chamber shells 4 are pushed to move and contact. When the two light-shielding dark chamber shells 4 are in contact, a light-shielding dark chamber will be formed on the stage 1. At the same time, the two detection ports 5 will correspond to form a detection hole, and the spectral gun head 10 performs Raman spectrum detection on the object in the light-shielding dark chamber through the detection hole; wherein, the three-axis adjustment component 2 is installed on the stage 1 and can adjust its position, so that the spectral gun head 10 in the gun head fixing frame 3 can be adjusted in the XYZ three axes according to the object to be detected.

[0031] Specifically, the three-axis adjustment assembly 2 includes a dual-axis mounting adjustment frame 21, a Z-axis slide rail 22 and a Z-axis slide seat 23.

According to the actual situation of the object to be detected, the dual-axis mounting adjustment frame 21 can be installed to adjust the X-axis and Y-axis positions so that the spectral gun tip 10 in the gun tip fixing frame 3 corresponds to the object to be detected. The Z-axis slide 23 is connected to the Z-axis slide rail 22 through a sliding connection, and can drive the spectral gun tip 10 in the gun tip fixing frame 3 to move up and down to achieve Z-axis adjustment.

[0040] In this embodiment, the housing of the Raman detection instrument is connected via the “L”-shaped hanging bracket 9, so that the entire detection bracket can be hung on the housing of most Raman detection instruments as an accessory.

[0041] Working principle: When performing Raman detection on an object, the object to be detected is placed on the stage 1, and the Raman detector performs Raman spectrum detection on the object through the spectrum gun head 10. When it is necessary to perform Raman detection on the object outdoors or in an environment where the light source cannot be turned off, the object to be detected is placed on the stage 1 by pulling the two light-shielding dark chamber shells 4, and then the two light-shielding dark chamber shells 4 are pushed to move and contact, and the spectrum gun head 10 performs Raman spectrum detection on the object in the two light-shielding dark chamber shells 4 through the two detection ports 5. After the detection is completed, the object can be taken out by pulling open the two light-shielding dark chamber shells 4.
