[0024] This embodiment provides a magnetically attached visual spectrometer for physics teaching, such as... Figures 1-4 As shown, the spectrometer includes a laser beam splitter 1 and a prism 2. A support 3 is fixedly installed at the bottom of the laser beam splitter 1, and a first magnetic chuck 32 is fixedly installed at the bottom of the support 3. A vernier dial 4 is movably installed on the support 3.

[0025] An annular groove 41 is provided on the outer edge of the vernier disk 4. A slider 31 adapted to the annular groove 41 is fixedly installed on the support 3 at one end of the light source emitting end of the laser beam splitter 1. The slider 31 is slidably installed in the annular groove 41. A turntable 44 is rotatably installed on the vernier disk 4. A slot 45 for placing the triangular prism 2 is provided on the turntable 44. The triangular prism 2 is snapped into the slot 45. A second magnetic suction piece 42 is fixedly installed at the bottom of the vernier disk 4 and is flush with the first magnetic suction piece 32.

[0026] In use, attach the side of the vernier caliper 4 with the second magnetic piece 42 to the blackboard, and then attach the side of the support 3 with the first magnetic piece 32 to the blackboard. Before attaching, insert the slider 31 on the support 3 into the annular groove 41, and then insert the prism 2 into the slot 45. Then turn on the laser beam splitter 1 to illuminate the prism 2. Manually push the support 3 to rotate along the annular groove 41 to adjust the illumination angle. After adjustment, release your hand, and the light will be visible on the vernier caliper 4. During the experiment, there is no need to manually support the laser beam splitter 1 and the prism 2, and the illumination angle can be identified by the scale on the vernier caliper 4. The installation is stable and there will be no shaking, thereby improving the stability of the equipment, improving the accuracy of the experiment, and making it more suitable for teaching.

[0027] Specifically, the inner wall of the slider 31 is an arc surface adapted to the annular groove 41, and the light source emitting end of the laser beam splitter 1 always extends towards the center of the vernier disk 4. In use, the support 3 is pushed to make the slider 31 rotate within the annular groove 41, ensuring that the light source of the laser beam splitter 1 always shines on the center of the vernier disk 4, thus ensuring experimental accuracy.

[0028] More specifically, an outer scale marking ring 49 is fixedly installed on the vernier dial 4 near the edge of the annular groove 41. In use, when the support 3 is rotated, the light source emitted by the laser beam splitter 1 shines through the outer scale marking ring 49, thereby determining the accurate illumination angle, making it more accurate and reliable.

[0029] Further, the vernier disc 4 is provided with a rotating cavity 43 at the center position, and the rotating disc 44 is rotatably installed in the rotating cavity 43. In use, the rotating disc 44 is rotated in the rotating cavity 43 by rotating the prism 2, so as to change the angle of the prism 2, and more experimental data is provided.

[0030] Further, the spring 46 is fixedly installed at one end of the clamping groove 45, the anti-skid piece 47 is fixedly installed at the other end of the clamping groove 45, and the anti-skid groove 48 is formed in the anti-skid piece 47. In use, the prism 2 is first placed in the clamping groove 45 at the end with the spring 46, and then the prism 2 is pushed to compress the spring 46, and then the other end of the prism 2 is placed in the clamping groove 45 at the end with the anti-skid piece 47, and the spring 46 is pushed to the side of the anti-skid piece 47 by the elastic force, so as to clamp the prism 2 in the clamping groove 45, and prevent the prism 2 from being separated, and the anti-skid groove 48 further improves the friction, and ensures the stability of the installation of the prism 2.

[0031] Further, the inner scale mark ring 410 is fixedly installed at the edge of the rotating cavity 43 of the vernier disc 4. In use, the rotating angle of the prism 2 can be observed when the rotating disc 44 is rotated, and the accurate angle is recorded conveniently.
