[0002] Right-angle prisms are usually used to turn the light path or deflect the image formed by the optical system by 90°. Depending on the orientation of the prism, the image can be consistent left and right and upside down or inconsistent left and right and consistent up and down. Right-angle prisms can also be used for applications such as image combination and beam deviation. When right-angle prisms are used, they are usually coated with some optical films. Right-angle prisms themselves have a large contact area and typical angles such as 45° and 90°. Therefore, compared with ordinary reflectors, right-angle prisms are easier to install and have better stability and strength to mechanical stress. They are the best choice for optical components for various devices and instruments.

[0025] Furthermore, a first movable groove 102 is provided at the middle upper end of the circular groove 101 , and a first reset ring 201 is fixedly connected to the middle of the ventilation pipe 2 and at the upper end inside the first movable groove 102 .

[0026] Furthermore, a first spring 202 is provided inside the first movable groove 102 and at the lower end of the first reset ring 201. When the ventilation pipe 2 descends under pressure, the first reset ring 201 descends along the first movable groove 102 and presses down the first spring 202. When the ventilation pipe 2 is released from pressure, the first reset ring 201 is pushed up by the first spring 202, thereby causing the first reset ring 201 to drive the ventilation pipe 2 to rise.

[0027] Furthermore, a circular hole 301 is provided in the middle of the suction cup 3 , and the circular hole 301 is communicated with the inside of the ventilation pipe 2 . The middle of the ventilation pipe 2 , the middle of the flexible telescopic tube 203 and the middle of the first reset ring 201 are communicated with each other.

[0028] Furthermore, the lower end of the ventilation pipe 2 is fixedly connected to the lower end of the first movable groove 102, and the lower end of the ventilation pipe 2 is connected to the inside of the main ventilation groove 105 through the circular branch ventilation groove 104, so that the air inside the entire device is connected.

[0029] Furthermore, the middle portion of the movable tube 4 is connected to the main ventilation groove 105 through the middle opening of the second reset ring 401 .

[0030] Furthermore, a second spring 402 is provided inside the second movable groove 106 and on one side of the second reset ring 401. When the second spring 402 is not subjected to force, the air-closing cap 404 on one side of the movable tube 4 fits with the end face of one side of the fixture seat 1 to achieve airtightness. At this time, the rectangular air vent 403 on the movable tube 4 is inside the fixture seat 1, thereby isolating the main air vent 105 from the external air. When the movable tube 4 is forced to extend outward, the second reset ring 401 is synchronously driven to move along the inside of the second movable groove 106 and compress the second spring 402. When the force is released, the second reset ring 401 is pushed to move by the second spring 402, thereby driving the movable tube 4 to reset.

[0031] Working principle: when in use, install the whole device on the coating table of the coating machine, place the right-angle prism on the upper end of the four suction cups 3, press down the right-angle prism, and synchronously press down the four suction cups 3 through the right-angle prism, and then synchronously make the ventilation tubes 2 at the lower ends of the four suction cups 3 contract and descend through the flexible telescopic tube 203, so that the internal air pressure of the whole device increases, and the ventilation tube 2 synchronously drives the first reset ring 201 to descend along the inside of the first movable groove 102 and press down the first spring 202, and pushes the air-closing cap 404 through the air pressure, so that the air-closing cap 404 drives the movable tube 4 to move to one side, and the movable tube 4 synchronously drives the second reset ring 401 to move along the inside of the second movable groove 106 and compresses the second spring 402, so that the rectangular vent 403 moves out of the inside of the fixture seat 1, so that the air inside the fixture seat 1 The liquid is discharged through the main ventilation groove 105 via the rectangular ventilation port 403 on the movable tube 4. As the air pressure decreases, the second spring 402 gradually pushes the second reset ring 401 to move, thereby driving the movable tube 4 to reset, so that the rectangular ventilation port 403 is retracted into the inside of the fixture seat 1, and the air-closing cap 404 is fitted with the end face of one side of the fixture seat 1 to achieve sealing, and the right-angle prism is released. The first reset ring 201 is pushed up by the first spring 202, and then the first reset ring 201 drives the ventilation tube 2 to rise. Since the main ventilation groove 105 is closed, the air pressure inside the entire device is reduced, so that the four suction cups 3 stably absorb the lower end face of the right-angle prism. The entire device absorbs the lower end face of the right-angle prism without blocking the side face of the right-angle prism. When the right-angle prism is coated, the side face can be coated synchronously to improve efficiency.
