In this technical solution, the lens 3 is mounted and fixed on the mounting frame 2, and then the mounting frame 2 is mounted on the coated umbrella stand 1, so the lens 3 is flexibly fixed on the mounting frame 2. The specific fixing structure is to set a clamping device on the installation frame 2, such as setting a retractable clamping device protruding relative to the center around the corresponding fixing hole 2-1. When the lens 3 needs to be installed, it is only necessary to install the lens 3 in the fixing hole 2-1 and clamp it with the clamping device. When coating the front or back of the lens 3, it is convenient to disassemble the lens 3, and the tooling does not need to be disassembled. It is only necessary to properly adjust the clamping force of the clamping device on the lens 3. The structure is simple and easy to operate, which greatly improves the efficiency of employees in adjusting the tooling when coating the lens 3. There is no requirement for the material of the installation frame 2, and it only needs to open the fixing hole 2-1. The cost is low, which effectively reduces the cost of the enterprise.

[0029] Preferably, the mounting frame 2 has at least two fixing holes 2-1, and the coated umbrella stand 1 has at least two mounting holes 1-1. That is, at least two lenses 3 can be mounted on one mounting frame 2, and at least two mounting frames 2 can be mounted on one coated umbrella stand 1, and four lenses 3 can be coated at the same time, further improving the coating efficiency.

[0030] like Figure 3-Figure 6 As shown, the clamping device is installed at the relative positions on both sides of the fixing hole 2-1, and the clamping device includes a mounting block 2-3-1 and a fixing rod 2-3-2. The mounting block 2-3-1 is fixed to the mounting frame 2, and the mounting block 2-3-1 has an adjustment hole 2-3-7, and the fixing rod 2-3-2 is telescopically installed in the adjustment hole 2-3-7. The fixing rod 2-3-2 can be telescopically adjusted in the adjustment hole 2-3-7. A similar structure is provided, such as a threaded structure, where the fixing rod 2-3-2 can be screwed and moved in the adjustment hole 2-3-7 by the thread, or the fixing rod 2-3-2 can be moved under the action of elastic force with the help of a spring 2-3-4, etc.

[0031] Preferably, there are at least two adjustment holes 2-3-7 on the mounting block 2-3-1, and they are located at the two end positions of the mounting block 2-3-1. That is to say, a mounting block 2-3-1 has fixing rods 2-3-2 at both ends for clamping the lens 3. In this way, the structure is more stable, the clamping force is more balanced, and the clamping effect is better.

[0032] Preferably, the fixing rod 2-3-2 includes a mounting end 2-3-5 and an abutment end 2-3-6, the mounting end 2-3-5 has a thread, and a nut 2-3-3 is threadedly installed, and the nut 2-3-3 is located on one side of the mounting block 2-3-1; the abutment end 2-3-6 is located on the other side of the mounting block 2-3-1, and the cross-sectional diameter of the abutment end 2-3-6 is larger than the cross-sectional diameter of the fixing rod 2-3-2 body, and a spring 2-3-4 is installed between the abutment end 2-3-6 and the mounting block 2-3-1; the abutment end 2-3-6 in a natural state extends into the fixing hole 2-1. The spring 2-3-4 is arranged between the abutting end 2-3-6 and the mounting block 2-3-1, giving the abutting end 2-3-6 a certain elastic force. Under the action of the elastic force, the abutting end 2-3-6 in a natural state extends into the fixing hole 2-1. When installing the lens 3, the mounting end 2-3-5 can be pulled first to pull the abutting end 2-3-6 out of the fixing hole 2-1. At this time, the spring 2-3-4 is in a compressed state. After the lens 3 is placed in the fixing hole 2-1, the mounting end 2-3-5 is released. At this time, the abutting end 2-3-6 will move into the fixing hole 2-1 under the action of the spring 2-3-4 force until the lens 3 is clamped, thereby completing the clamping and fixing of the lens 3.

[0033] Preferably, the shape of the abutting end 2-3-6 is adapted to the edge of the lens 3 so as to better clamp the lens 3. A rubber cap is installed on the abutting end 2-3-6, and the rubber material is relatively soft to prevent damage to the lens 3 during the clamping process.

[0034] like Figure 2 and Figure 3 As shown, the front and back of the mounting frame 2 are both provided with outwardly protruding positioning ribs, namely, the front positioning rib 2-2 of the mounting frame and the back positioning rib 2-4 of the mounting frame. The outer diameter of the mounting frame 2 is larger than the diameter of the mounting hole 1-1, and the outer diameter of the positioning rib is smaller than the diameter of the mounting hole 1-1. The positioning rib is installed in the mounting hole 1-1. Similar to the common bottle caps or bottle stoppers in life, the positioning ribs are used to install and clamp into the mounting hole 1-1, and the mounting frame 2 is fixed on the coated umbrella stand 1. The installation is simple and convenient, and the operation is quick.

[0035] Working principle: When using this tool, first pull the mounting end 2-3-5 of the fixing rod 2-3-2 on the front of the mounting frame 2 to pull the abutting end 2-3-6 out of the fixing hole 2-1. At this time, the spring 2-3-4 is in a compressed state. After placing the lens 3 into the fixing hole 2-1, release the mounting end 2-3-5. At this time, the abutting end 2-3-6 will move into the fixing hole 2-1 under the action of the spring 2-3-4 force until the lens 3 is clamped, thereby completing the clamping and fixing of the lens 3. Then place the mounting frame 2 on the coated umbrella stand 1 for coating. After the coating is completed on the front of the lens 3, remove the lens 3 and turn it over to install the back side. The operation is the same as above.

[0036] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention.
