[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] A crystal optical performance testing device, such as Figures 1-4 As shown, it includes a base 1; the top of the base 1 is provided with a clamping mechanism 2, which can clamp and position the crystal particle to be tested, so that the crystal particle is kept stable and positioned at the center of the clamping mechanism 2, thereby making the crystal particle and the test structure on the same vertical line, improving the test effect of the crystal particle.

[0026] Specifically, the clamping mechanism 2 includes a clamping seat 21, which is fixedly connected to the top center of the base 1. The clamping seat 21 has a cylindrical structure and is fixedly connected to the top of the base 1. The center of the clamping seat 21 corresponds to the position of the detection head. A clamping block 22 is rotatably connected to the inner side of the clamping seat 21. A clamping cloth 23 is fixedly connected to the end of the clamping block 22. The clamping block 22 can drive the clamping cloth 23 to pull inward, and clamp and position the side of the crystal particle through the middle of the clamping cloth 23, thereby improving the clamping and positioning effect of the crystal.

[0027] In addition, there are two sets of clamping blocks 22, each set of clamping blocks 22 has several, and each set of clamping blocks 22 is arranged around the inside of the clamping seat 21. The clamping blocks 22 have an arc-shaped structure. Each set of rotatably connected clamping blocks 22 can clamp different sides of the crystal particles by rotating, thereby improving the clamping and fixing effect on irregular crystals. At the same time, the arc-shaped clamping blocks 22 can form a structure similar to a camera shutter by combining with each other, keeping the center always circular during the clamping process, thus facilitating subsequent inspection operations.

[0028] Furthermore, a support rod 24 is fixedly connected to the end of the clamping block 22. The support rod 24 is rotatably connected inside the clamping seat 21. The structure of the support rod 24 can support the clamping block 22, allowing the clamping block 22 to rotate inside the clamping seat 21. A drive gear 25 is fixedly connected to the top of the support rod 24. A gear ring 26 is meshed with the outer side of the drive gear 25. All drive gears 25 are meshed with the inner side of the gear ring 26. The rotation of the gear ring 26 can drive the entire set of drive gears 25 and the clamping block 22 to rotate, thereby realizing the clamping operation of the clamping block 22 wrapping and clamping the crystal.

[0029] It is worth noting that there are two toothed rings 26, which are rotatably connected to the top and middle of the clamping seat 21, respectively. The position of each set of clamping blocks 22 corresponds to the position of the toothed rings 26. The top and bottom of the crystal particles can be clamped by the clamping blocks 22, so that the clamping cloth 23 presents a lantern-shaped structure, which improves the clamping stability of the two ends of the crystal particles.

[0030] Furthermore, a transmission gear set 27 is movably connected to one side of the clamping base 21. The two toothed rings 26 drive each other through the transmission gear set 27. The structure of the transmission gear set 27 can drive the toothed rings 26, causing the two toothed rings 26 to rotate in opposite directions. This allows the clamping structure at the top of the crystal particle to continuously tighten while the clamping block 22 at the bottom of the crystal particle to continuously relax. This ensures that the clamping blocks 22 at the top and bottom of the crystal particle maintain the same clamping tightness, thus facilitating subsequent optical inspection operations.

[0031] In addition, the transmission gear set 27 includes a housing 271, which is movably connected to the outside of the clamping seat 21. A locking block 272 is fixedly connected to one side of the housing 271. The locking block 272 facilitates the installation and fixation of the transmission gear set 27 to the outside of the clamping seat 21. Simultaneously, the outside of the clamping seat 21 has a corresponding locking groove for the locking block 272. A positioning frame 273 is slidably connected inside the housing 271. A buffer device 274, which is a buffer spring or damper, is connected to the outside of the positioning frame 273 to buffer the movement of the positioning frame 273. A driven gear 275 is rotatably connected to the inside of the positioning frame 273. A linkage gear 276 is connected to the driven gear 275. The linkage gear 276 includes three meshing conical drive gears 25, and the three linkage gears 276 mesh with each other in a U-shape, thereby ensuring that the two driven gears 275 rotate in opposite directions when they are mutually transmitting power.

[0032] Example 2

[0033] like Figures 1-4 As shown, based on Embodiment 1, a protective mechanism 3 is provided on the outside of the clamping mechanism 2, which can protect the operator during the test.

[0034] In this embodiment, a telescopic rod 35 is fixedly connected to the top of the base 1, and a movable seat 36 is fixedly connected to the end of the telescopic rod 35. A laser detection head is connected to the bottom of the movable seat 36. The structure of the telescopic rod 35 can adjust the height of the movable seat 36, thereby adjusting the laser detection head to a set position to perform optical detection on the crystal particles.

[0035] Based on this, the protective mechanism 3 includes a protective plate 31, which is rotatably connected to the top of the base 1. The protective plate 31 is located on the outside of the clamping seat 21. The protective plate 31 has an arc-shaped structure. The top of the base 1 has a sliding groove 32, which has a circular structure. A support ring 33 is slidably connected inside the sliding groove 32. The support ring 33 is fixedly connected to the bottom of the protective plate 31. The support ring 33 can support the protective plate 31, allowing the protective plate 31 to slide inside the sliding groove 32, thereby switching between protective and rotating opening.

[0036] Furthermore, a connecting rod 34 is rotatably connected to the inner side of the protective plate 31. The end of the connecting rod 34 meshes with the outer side of the toothed ring 26. The structure of the connecting rod 34 can connect the protective plate 31 and the toothed ring 26, so that the rotation of the protective plate 31 can drive the toothed ring 26 to rotate synchronously.

[0037] In use, the crystal optical performance testing device of this utility model first places the crystal particle to be tested inside the clamping base 21. Since the lower clamping block 22 is at its maximum clamping tightness in the initial state, it can support the crystal particle. Then, the upper gear ring 26 is rotated, which drives the upper clamping block 22 to rotate. During the rotation of the clamping block 22, the clamping opening formed between the inner sides of the clamping blocks 22 gradually narrows and clamps and fixes the top of the crystal particle. Then, the transmission gear set 27 is installed on the clamping base 21. If the gear ring 26 and the driven gear 275 are not meshed, the misaligned driven gear 275 is restricted by the gear ring 26 and pushes the positioning frame 273 inward. After the gear ring 26 rotates to mesh with the driven gear 275, the positioning frame 273, under the push of the buffer device 274, makes the driven gear 275 mesh with the gear ring 26. Then, the connecting rod 34 is rotated so that its end rotates onto the upper gear ring 26, connecting the protective plate 31 to the upper gear ring 26. The protective plate 31 is then rotated to shield the top front of the base 1. While the protective plate 31 rotates, it drives the upper gear ring 26 to rotate via the inner connecting rod 34. Simultaneously, the lower gear ring 26 rotates in the opposite direction under the transmission gear set 27, causing the upper clamping block 22 to rotate inward to lock and the lower clamping block 22 to rotate outward to loosen, ensuring that both ends of the clamping cloth 23 are in the same clamping state.
