The bottom surface light source 62 adopts a ring light source design to ensure uniform illumination of the bottom surface of the braid.

[0033] like Figure 4 As shown, the first angle adjustment member 34 includes a first angle adjustment block 341, one end of which is connected to the first support frame 31, and the other end is provided with a light source mounting plate 342. A mounting hole 343 is provided at the lower part of the light source mounting plate 342, and a plug-in hole 321 is correspondingly provided on the side of the front light source 32. The front light source 32 is rotatably arranged on the light source mounting plate 342 through the mounting hole 343. A first arc-shaped groove 344 is provided at the upper part of the light source mounting plate 342, and a first limiting hole 322 is correspondingly provided on the side of the front light source 32.
