Due to the limitation of the support plate 303 by the two connecting plates 308, the screw rod 302 drives the support plate 303 to rise or fall when it rotates, and the support plate 303 drives the first hinged plate 304 to fall synchronously when it falls, and the first hinged plate 304 is moved downward. The hinged plate 304 drives one end of the connecting plate 308 to descend synchronously. Since the second hinge shaft 309 at the other end of the connecting plate 308 is hinged to the second hinged plate 307, the connecting plate 308 drives the slider 306 to slide along the slide groove 305, so that the two sliders 306 are close to each other, and then the slider 306 drives the positioning mechanism 500 to move synchronously, so that the positioning mechanism 500 drives the two prism bodies 400 to approach each other to clamp and fix them, thereby improving the clamping stability of the prism, avoiding the situation that the prism is skewed or not glued tightly, and improving the practicality of the device;

The staff places one side of the prism body 400 between the two L-shaped positioning plates 505, and then turns the handle 504, and the handle 504 drives the bidirectional screw 503 to rotate, and the rotation of the bidirectional screw 503 drives the two movable blocks 502 When the movable blocks 502 are moved closer to or farther away from each other, they drive the L-shaped positioning plates 505 to move synchronously, so that the two L-shaped positioning plates 505 can fix the prism body 400, so that prisms of different sizes can be fixed, thereby improving the applicability of the device and further improving the stability of the gluing process; rubber pads are arranged on the surface of the L-shaped positioning plates 505 to prevent wear on the prism body 400; guide blocks 507 are arranged on the upper and lower sides of the movable block 502, a through hole is opened in the center of the guide block 507, and a guide rod 506 is arranged through the through hole in the center of the guide block 507, and both ends of the guide rod 506 are fixed to the inner wall of the fixed frame 501, and the guide blocks 507 prevent the movable block 502 from tilting, thereby improving the stability of the movable block 502 during the movement process; the surface of the handle 504 is provided with anti-slip threads to prevent human hands from slipping.

[0023] The use of this utility model:

[0024] The staff places one side of the prism body 400 between the two L-shaped positioning plates 505, and then turns the handle 504, which drives the bidirectional screw 503 to rotate. When the bidirectional screw 503 rotates, it drives the two movable blocks 502 to move closer to or away from each other. When the movable blocks 502 move closer to each other, they drive the L-shaped positioning plates 505 to move synchronously, so that the two L-shaped positioning plates 505 are close to each other to fix the prism bodies 400 of different sizes. Then, the staff turns the handle 311, which drives the screw rod 302 to rotate. Due to the limitation of the two connecting plates 308 on the support plate 303, the screw rod 302 drives the support plate 303 to rise or fall when it rotates, and the support plate 303 is supported. When the support plate 303 descends, the first hinge plate 304 is driven to descend synchronously, and the first hinge plate 304 drives one end of the connecting plate 308 to descend synchronously. Since the second hinge shaft 309 at the other end of the connecting plate 308 is hinged to the second hinge plate 307, the connecting plate 308 drives the slider 306 to slide along the slide groove 305, so that the two sliders 306 are close to each other, and then the slider 306 drives the positioning mechanism 500 to move synchronously, so that the positioning mechanism 500 drives the two prism bodies 400 to approach each other to clamp and fix them, thereby improving the clamping stability of the prism, avoiding the situation that the prism is skewed or not glued tightly, and improving the practicality of the device.
