[0013] In the figure: 1 working frame, 2 cam, 3 push rod, 4 limit rotating rod, 401 vertical rod, 402 horizontal rod, 5 tension spring, 6 placement groove, 7 hinge seat, 8 rotating shaft, 9 rotating handle, 10 adjusting block, 11 limit bolt. DETAILED DESCRIPTION

[0014] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1As shown, an optical coating fixture includes a work frame 1, a cam 2 is rotatably connected in the work frame 1, and a push rod 3 is inserted in the work frame 1 on both sides of the cam 2. The work frame 1 is hinged with a limit rotating rod 4 on both sides of the work frame 1. The inner end of the push rod 3 abuts on the surface of the cam 2, and the outer end of the push rod 3 abuts on the lower part of the limit rotating rod 4. The lower free ends of the two limit rotating rods 4 are connected through a tension spring 5. A placement groove 6 for placing optical parts is provided on the upper surface of the work frame 1. The limit rotating rod 4 is L-shaped, including an integral vertical rod 401 and a horizontal rod 402. A hinge seat 7 is provided on the side of the work frame 1. The hinge seat 7 is hinged to the middle of the vertical rod 401, and the free end of the horizontal rod 402 abuts on the surface of the optical part. A rotating shaft 8 is inserted into the cam 2, and a rotating handle 9 is integrally arranged outside the rotating shaft 8. A torsion spring is sleeved on the rotating shaft 8. When the rotating shaft 8 rotates counterclockwise, the torsion spring is in a tensioned state. An adjustment block 10 is arranged on the working frame 1 located on the side of the rotating handle 9. A horizontal limit bolt 11 is screwed into the adjustment block 10. The free end of the limit bolt 11 abuts against the side of the rotating handle 9 to limit the clockwise rotation of the rotating handle 9. A sponge rubber sleeve is sleeved on the free end of the crossbar 402. Both free ends of the top rod 3 are spherical.

[0016] When the present scheme is working, the operator places the mold embedded with the optical part to be coated into the placement groove 6, rotates the rotating handle 9 counterclockwise, so that the cam 2 rotates counterclockwise, and the cam 2 squeezes the top rod 3 located in the working frame 1, so that the top rod 3 moves toward the outside of the working frame 1, and squeezes the corresponding limiting rotating rod 4 to rotate toward the inside of the working frame 1, so that the free end of the cross bar 402 of the limiting rotating rod 4 abuts against the edge of the optical part to be coated. After the abutment, the limiting bolt 11 is rotated so that the free end of the limiting bolt 11 abuts against the rotating handle 9, and the rotating handle 9 is restricted from rotating clockwise due to the reset action of the torsion spring. At the same time, in the process of fine-tuning the limiting bolt 11, the clamping degree of the limiting rotating rod 4 on the optical part to be coated can be adjusted.

[0017] 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.
