[0013] Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, this utility model includes a mounting bracket body 1, locking rings 2, locking screws 3, and rubber rings 4. The mounting bracket body 1 is square-shaped and located on the outside, with a circular hole inside. Locking rings 2 are located on the upper and lower sides of the circular hole. The locking rings 2 are circular and embedded in the center of the mounting bracket body 1. Two locking screws 3 are located on the outside of the mounting bracket body 1 for fixing the cage system connecting rods. The mounting bracket body 1 has four through holes of equal diameter for assembling cage systems with a spacing of 30mm. The rubber rings 4 are embedded inside the two locking rings 2 and fit snugly against them. Figure 2 As shown.

[0016] The entire structure is made of alumina ceramic and consists of a mounting bracket body 1, a locking ring 2, and locking screws 3. It has four through holes with a diameter of 6mm, which can be used to assemble a cage system with a spacing of 30mm.

[0017] Instructions for use: Remove the locking ring, insert the component into the main body hole, and tighten after installing the locking ring. When installing the cage system, secure the cage system connecting rod with locking screw 3.

[0018] A plastic ring 4 is inlaid on the ceramic locking ring using an interlocking process, which can prevent damage to the optical lens and provide stress relief space.

[0019] The main body is made of alumina ceramic material, which is non-magnetic and has small thermal deformation. A plastic spacer is embedded in the contact surface between the locking ring and the lens to protect the lens and provide some stress release space. An exhaust hole is added to the top of the frame to prevent air entrapment, so it can be used in a vacuum environment.
