The threaded connection method for adjusting the discharge plate has high precision, good flexibility, and a wide adjustment range. It can be used for drying and placing medicines of more sizes, thereby saving space and improving efficiency.

[0014] 2. The utility model uses the installation groove, the extension groove and the threaded mouth to cooperate with the adjusting rod installed in the groove outside the threaded rod. The adjusting rod can be stored or unfolded on the outside of the threaded rod according to the use requirements. When the adjusting rod is stored, it is completely integrated into the groove, and does not affect the movement of the movable thread sleeve on the outside of the threaded rod. When the spacing of the discharge plates is adjusted, it is necessary to add or remove the discharge plates on the outside of the threaded rod to change the number of discharge plates to adapt to the spacing arrangement of the discharge plates. The adjusting rod can be unfolded to enable human power to act on the threaded rod to rotate, so that the threaded rod can be rotated and adjusted to move out of the threaded mouth to move toward the extension groove. After the threaded rod is disconnected, the part disconnected from the threaded mouth can be used for adding or removing the discharge plates, so that the number of discharge plates can correspond to the spacing arrangement of the discharge plates. After the disassembly and assembly are completed, the threaded rod can be reconnected to the threaded mouth to continue to play the role of support and guidance. The process is simple to operate and the space occupancy efficiency in the drying box is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
