[0042] In some embodiments of the utility model, as shown in Figures 1 to 4 The jig body 100 is provided with a level 108, and the length direction of the level 108 is parallel to the first contact end surface 103. In the embodiment, the debugging jig is provided with the level 108, and the length direction of the level 108 is parallel to the first contact end surface 103. After the debugging jig is positioned with the light source 200 and the test jig 300 respectively, whether the first end surface 201 of the light source 200 and the second end surface 302 of the camera module are in a horizontal state, that is, whether the center lines of the light source 200 and the camera module extend along the vertical direction, can be observed in real time and conveniently through the level 108.

It is provided with a closed containing cavity, and the cavity contains special liquid, which can be a mixture of alcohol, glycerol, ethylene glycol and water, and has the characteristics of not freezing, good fluidity and strong stability. When the length direction of the level 108 is inclined, the internal liquid will also be inclined, but the liquid surface always remains horizontal. The position of the bubbles in the level 108 reflects the inclination degree of the measured object. When the level 108 is in a horizontal position, the bubbles will occupy the highest position in the middle of the length direction of the level 108. If the level 108 is inclined to one end, the bubbles will move to the highest position at one end of the length direction of the level 108. By observing the position of the bubbles, it can be quickly known whether the level 108 is in a horizontal state, so that it can be known in time whether the light source 200 and the camera module are in a horizontal state, to facilitate the staff to make quick adjustment.
