Supporting tool and marking device for short-wave infrared detector tube shell

The utility model provides a supporting tool for a short wave infrared detector tube shell and a marking device. The supporting tool for the short-wave infrared detector tube shell comprises a positioning part and a main body part, a limiting groove is formed in the top of the main body part, and the shape of the limiting groove is matched with the shape of the bottom of the short-wave infrared detector tube shell. The supporting tool for the short wave infrared detector tube shell is detachably connected to a marking platform through the positioning part. According to the supporting tool for the short-wave infrared detector tube shell and the marking device, accurate positioning between the short-wave infrared detector tube shell and a laser marking machine during marking is achieved, the influence on the marking process due to the fact that the short-wave infrared detector tube shell and the laser marking machine are not placed in place is reduced, the preparation time of the marking process is shortened, t
