An X-ray diffractometer sample stage for bulk solid samples is disclosed. In use, the base is moved to the designated position, and the bulk solid sample is placed on the sample stage within the sample placement groove and secured with modeling clay. Since there are three wedge mechanisms arranged in a triangle, based on the principle that three points not on the same straight line can define a plane, the three wedge mechanisms can support the sample stage. Furthermore, because the wedge mechanisms drive the bottom of the sample stage and can convert horizontal movement into vertical movement, the corresponding parts of the sample stage can be raised or lowered by the wedge mechanisms, thereby adjusting the height and angle of the sample stage. This eliminates the need for cutting or processing the bulk solid sample, simplifying operation. When the sample quantity is small, there is no need to lay a large amount of modeling clay on the sample stage, making it more convenient to use. In summary, by using this sample stage, the depth and angle of the sample stage can be adjusted.
