[0028] It should be noted that by rotating the rocker 63 clockwise, the threaded rod 68 is driven to rotate clockwise, and the threaded rod 68 and the threaded plate 69 are threadedly connected, thereby driving the threaded plate 69 to move rightward along the square groove 60, thereby driving the movable plate 64 to move rightward, and at the same time, the limit block 62 will slide along the limit groove 61. The limit groove 61 and the limit block 62 are both T-shaped blocks, which prevent the movable plate 64 from tipping over and ensure the stability of the movable plate 64, thereby driving the irradiation lamp 66 and the camera 67 to move to the right. The right end is moved, and the distance between the irradiation lamp 66 and the gear detection part 4 can be adjusted by rotating the rocker 63, so that the shadow presentation effect is better.

If there is any inconsistent part between the gear detection component 4 and the gear template 75, it will be irradiated onto the light receiving plate 2 by the light source. At the same time, the camera 2 73 provided will take a picture of the downward direction, and transmit the data of the invisible part formed to the data display screen 8, so that the shape of the gear detection component 4 can be analyzed and detected, and the pull plate 701 is pulled outward, thereby driving the baffle 79 to move outward, so that the spring 77 is compressed, so that the gear template 75 can be removed, which is convenient for replacing gear templates 75 of different sizes, so that gear detection components 4 of different sizes can also be detected, thereby achieving higher practicality.

The limit groove 61 and the limit block 62 are both T-shaped blocks, which prevent the moving plate 64 from tipping over and ensure the stability of the moving plate 64, thereby driving the irradiation lamp 66 and the camera 67 to move rightward. By moving the rocker 63, the distance between the irradiation lamp 66 and the gear detection part 4 can be adjusted to make the shadow presentation effect better. By energizing the irradiation lamp 66, the irradiation lamp 66 emits a light source, which will irradiate to the right end and then illuminate the gear detection part 4, and present a shadow part on the side panel 5.
