Detailed Embodiments

[0015] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0016] Such as Figure 1 - Figure 2As shown in the figure, the detection light source includes a light source body 11. There are connecting ears 12 on the light source body 11. The connecting ears 12 are connected to a regular polygon groove block 16. The regular polygon groove block 16 is connected to a switching shaft 21. A regular polygon block 18 is movably connected to the switching shaft 21, and the regular polygon block 18 can be inserted into the regular polygon groove block 16. There is also a return spring 20 between the switching shaft 21 and the regular polygon groove block 16. In this embodiment, the number of sides of the regular polygon block 18 and the regular polygon groove block 16 is twenty. With this structure, when the irradiation angle needs to be adjusted, only need to pull the light source body 11 outwards to separate the regular polygon groove block 16 from the regular polygon block 18. After rotating to the desired position, engage the regular polygon groove block 16 with the regular polygon block 18. By using the return spring 20, the two can be reliably connected together. Specifically: A limiting block 19 is detachably connected to the rear end of the switching shaft 21. One end of the return spring 20 abuts against the limiting block 19, and the other end of the return spring 20 abuts against the regular polygon block 18. There are at least two fixing ears 17 on the regular polygon groove block 16.

[0017] Strip-shaped holes are provided in the fixing ears 17.
