[0002] A multi-stage wave plate is an optical device, also known as a phase delay plate. It changes the polarization state of light by generating an optical path difference (or phase difference) between two mutually orthogonal polarization components. When the incident light passes through wave plates with different parameters, different output lights can be obtained, such as linearly polarized light, elliptically polarized light, circularly polarized light, etc. When using a multi-stage wave plate, it needs to be cut accordingly to meet actual needs.

[0003] According to a cutting device for quartz wave plate processing with application number CN202023093519.9, this solution solves the problem of how to avoid damage to the blade caused by the cutting mechanism pushing too fast and extend the service life of the blade.

[0004] However, the following problems still exist in actual use:

[0005] (1) When fixing the wave plate, the wave plate is fixed and cut by the negative pressure suction effect of the negative pressure vacuum pump, but it is not suitable for fixing a large number of wave plates, which will reduce the practical adaptability and is not conducive to the promotion and use in practice.
