A base 4 is provided under the bracket 1, which is fixed on the assembly line of the production line or the position where the product needs to be inspected through the base 4. During the inspection process, the product in the tooling may occasionally be lifted up, and the optical fiber 2 or the optical fiber lens 3 is often close to the product, and the optical fiber 2 or the optical fiber lens 3 is unprotected, which may easily cause the product to bump against the optical fiber 2 or the optical fiber lens 3, causing the position of the optical fiber 2 or the optical fiber lens 3 to change, affecting the inspection of the product, and then affecting the production of the automatic production line. In severe cases, the optical fiber 2 or the optical fiber lens 3 may even be damaged. Summary of the Invention

[0005] As a further improvement of the above technical solution:

[0006] The diameter of the upper end portion is greater than the diameter of the lower end portion.

[0007] The protective plate is provided with a through hole for accommodating the insertion of the lower end portion.

[0008] The nut is close to the bottom of the groove.

[0009] The bottom of the upper end portion is in contact with the protective plate.

[0010] The diameter of the through hole is 0.2 mm larger than the diameter of the lower end portion.

[0011] The distance from the lower end to the bottom of the protective plate is 1-3 mm.

[0012] The plurality of mounting openings are arranged in a straight line.

[0013] The installation opening is a U-shaped notch.

[0014] Due to the adoption of the above technical solution, compared with the existing technology, the advantages of the present invention are: the present invention arranges the optical fiber and the optical fiber lens inside, and when the product is tilted and collides, it can only hit the bottom of the protective plate and cannot collide with the optical fiber and the optical fiber lens, thereby protecting the optical fiber and the optical fiber lens, improving the stability of the automatic production line, and reducing production losses.
