[0012] Figure 1 It is a structural schematic diagram of the utility model.

[0013] Figure 2 for Figure 1 A partial enlarged view of point A in the middle.

[0014] In the figure: 1 workbench, 2 placing table, 3 fixed frame, 4 sliding shaft, 5 clamping head, 6 triangle plate, 7 first connecting rod, 8 L-shaped rod, 9 lead screw, 10 rotating rod, 11 lead screw nut, 12 second connecting rod, 13 articulated seat. DETAILED DESCRIPTION

[0015] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, a coating fixture for optical crystals applicable to multiple sizes is provided, including a workbench 1, a placement table 2 for placing optical crystals is provided in the center of the horizontal workbench 1, and a plurality of clamping components are provided around the placement table 2, the clamping components including a fixing frame 3, a sliding shaft 4 is connected inside the fixing frame 3, a clamping head 5 is connected to one end of the sliding shaft 4 facing the placement table 2, a triangular plate 6 is connected to the other end of the sliding shaft 4, the top angle of the triangular plate 6 is connected to the sliding shaft 4, the two bottom angles of the triangular plate 6 are respectively hinged to the first connecting rod 7, an L-shaped rod 8 is hinged to the fixing frame 3, the vertical section free end of the L-shaped rod 8 is hinged to the free end of the first connecting rod 7, and the horizontal section of the L-shaped rod 8 is connected to the adjusting component. The adjusting component includes a screw rod 9 horizontally provided on the fixing frame 3, a rotating rod 10 is connected to the free end of the screw rod 9, a screw nut 11 is matched and connected to the screw rod 9, a second connecting rod 12 is hinged to both sides of the screw nut 11, and the free end of the second connecting rod 12 is hinged to the free end of the L-shaped rod 8. The clamping head 5 includes an arc-shaped clamping plate, and a rubber pad is attached to the inner concave surface of the clamping plate. A hinge seat 13 is provided at the lower end of the free end of the horizontal section of the L-shaped rod 8, and the outer end of the second connecting rod 12 is connected to the hinge seat 13. At least three groups of clamping parts are provided, and the three groups of clamping parts are radially evenly distributed with the center of the placement table 2 as the center of the vertical axis.

[0017] When the present solution is working, the operator fixes the optical crystal to be coated on the placement table 2. When the clamping position of the clamping head 5 needs to be adjusted, the operator rotates the rotating rod 10. When the rotating rod 10 rotates, the screw nut 11 moves horizontally on the screw 9. When the screw nut 11 moves toward one side of the rotating rod 10, the L-shaped rod 8 is driven to rotate toward the outside of the fixed frame 3 through the second connecting rod 12. At this time, the vertical section of the L-shaped rod 8 pulls the first connecting rod 7 toward the outside of the workbench 1, thereby moving the clamping head 5 away from the placement table 2 through the sliding shaft 4, thereby expanding the clamping area. Conversely, when the rotating rod 10 is rotated in the opposite direction, when the screw nut 11 moves away from the rotating rod 10, the L-shaped rod 8 is driven to rotate toward the inside of the fixed frame 3 through the second connecting rod 12. At this time, the vertical section of the L-shaped rod 8 pulls the first connecting rod 7 toward the inside of the workbench 1, thereby moving the clamping head 5 toward the placement table 2 through the sliding shaft 4, thereby reducing the clamping area, thereby adapting to the size specifications of different optical crystals.

[0018] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
