[0023] like Figures 1 to 8As shown, an optical self-centering lens holder includes a mounting base 1. Several swing arms 2 are mounted on the mounting base 1, with one end of each swing arm 2 rotatably connected to the mounting base 1 and a clamping block 3 fixedly connected to the other end. The clamping blocks 3 cooperate to clamp the laser lens. A circular mounting groove 4 is formed on the mounting base 1, and the swing arms 2 are arranged in a ring around the center of the groove 4. A transmission mechanism 5 is installed within the groove 4, driving the swing arms 2 to move simultaneously. A support is provided on the rear side of the mounting base 1. The support base 6 is L-shaped. The same mounting hole 7 is provided on both the mounting base 1 and the support base 6. The mounting hole 7 passes through the mounting base 1 and the support base 6. The mounting groove 8 is provided on the mounting hole 7. The mounting groove 8 of the mounting hole 7 on the mounting base 1 is located at the front end, and the mounting groove 8 of the mounting hole 7 on the support base 6 is located at the rear end. A fixing rod 9 is fixedly connected in the mounting groove 8 on the mounting base 1 and the support base 6 respectively. A tension spring 10 is installed between the two fixing rods 9. The tension spring 10 is located in the mounting hole 7, thereby fixing the mounting base 1 to the support base 6.
[0024] Furthermore, a plurality of push rods 11 are provided on the support base 6, and the push rods 11 are connected to the support base 6 by threads. A ball bearing 13 is fixedly connected to the top of the push rod 11. The mounting base 1 has a number of mounting grooves 12 corresponding to the push rods 11. A pad block 14 is fixedly connected in the mounting groove 12. A ball groove 15 that mates with the ball bearing 13 is opened on the pad block 14. A support block 16 is fixedly connected to the other end of the push rod 11. One end of the support block 16 is flush with the lower surface of the support base 6. 6 can improve the stability of the support base 6. In the initial state, the three push rods 11 hold the mounting base 1 in place, leaving a certain gap between the mounting base 1 and the support base 6. During testing, the extension or retraction of the push rods 11 can be controlled by rotating the push rods 11. Under the action of the tension spring 10, the mounting base 1 will tilt to a certain extent as the push rods 11 extend or retract. The ball bearings 13 and the pads 14 can ensure that the mounting base 1 will not be jammed. This allows the frame to be finely adjusted for the laser lens according to the actual situation during the test.
[0025] In one embodiment, the transmission mechanism 5 includes a disc 17, fastening bolts 18, a mounting disc 19, and a mounting disc 20. The disc 17 is rotatably connected to a mounting groove 4, with its sidewall fitting against the sidewall of the mounting groove 4. A groove 21 is formed at one end of the mounting groove 4, and a groove 22 is formed at the other end. The mounting disc 19 is fixedly connected to one end of the disc 17 and rotates within the groove. The mounting disc 20 is fixedly connected to the other end of the disc 17 and rotates within the groove 22. A lever 2 is fixedly connected to the mounting disc 19. The corresponding guide rod 23 has a groove 24 on the swing rod 2. The guide rod 23 slides in the groove 24. A fastening bolt 18 is installed on the top of the mounting base 1. The fastening bolt 18 is connected to the mounting base 1 by a thread. One end of the fastening bolt 18 passes through the mounting groove 4 and rests on the disc 17. The fastening bolt 18 can be tightened to make it press against the disc 17, thereby restricting the rotation of the disc 17. Alternatively, the fastening bolt 18 can be loosened to allow the disc 17 to move. Moving the disc 17 causes the guide rod 23 on the mounting plate 19 to rotate, thereby driving the swing rod 2 on the mounting base 1 to open or close simultaneously.
[0026] Furthermore, a handle 25 is fixedly connected to the mounting plate 20, which makes it easier to rotate.
[0027] In another embodiment, the transmission mechanism 5 includes a second disc 26, a third mounting disc 27, a fourth mounting disc 28, a gear 29, and a gear ring 30. The second disc 26 is rotatably connected to the first mounting groove 4, and the side wall of the second disc 26 fits against the side wall of the first mounting groove 4. A third groove 31 is formed at one end of the first mounting groove 4, and a fourth groove 32 is formed on the mounting base 1. The third mounting disc 27 is fixedly connected to one end of the second mounting disc 20 and is fixedly connected to the third groove 31. The fourth mounting disc 28 is fixedly connected to the other end of the second disc 26 and is fixedly connected to the fourth groove 32. One side of the fourth mounting disc 28 is flush with the outermost side of the fourth groove 32. The gear ring 30 is disposed in the fourth groove 32. Inside the groove 32, the gear ring 30 is rotatably connected to the disc 26. A number of gears 29 corresponding to the number of swing rods 2 are provided in the groove 32. A rotating rod 33 is fixedly connected to the swing rod 2. The rotating rod 33 is rotatably connected to the mounting base 1. One end of the rotating rod 33 extends into the groove 32 and is fixedly connected to the gear 29. The gear 29 meshes with the gear ring 30. A support rod 34 is fixedly connected to one of the rotating rods 33. One end of the support rod 34 extends out of the mounting plate 4. By rotating the support rod 34, the gear 29 on the rotating rod 33 fixed to the support rod 34 can be rotated. The gear 29 drives the gear ring 30 to rotate, thereby driving the other gears 29 to rotate, so that the swing rod 2 opens or closes at the same time.
[0028] Furthermore, a protrusion 35 is provided on the mounting plate 28, and the support rod 34 rotates within the protrusion 35. A slot 36 is provided at the top of the protrusion 35, and a bushing is slidably connected to the support rod 34. A locking block 38 is fixedly connected to the bottom of the bushing, and the locking block 38 cooperates with the slot 36. Several locking blocks 39 are fixedly connected to the support rod 34, and a slot 37 is provided on the bushing to cooperate with the locking blocks 39. After aligning the slot 37 with the locking blocks 39, the bushing is lowered. When the lower surface of the bushing is in contact with the upper surface of the protrusion 35, the locking blocks 39 are located in the slot 37, and the locking blocks 38 are located in the slot 36. A rubber pad is fixedly connected in the slot 36. The rubber pad can increase the friction, which ensures that the bushing can restrict the rotation of the support rod 34 and prevent the laser lens from falling off due to the support rod 34 rotating on its own during the test.
[0029] Working principle of the utility model: The toggle block installed on the mounting base 1 is opened simultaneously by the toggle transmission mechanism 5. The opening degree of the swing arm 2 is controlled according to the size of the laser lens to adapt to different sizes of laser lenses. Then, the toggle transmission mechanism 5 is tightened so that the clamping block 3 holds the laser lens. The tilt of the mounting base 1 can be adjusted by adjusting the position of the top rod 11 to make fine adjustments.
