[0041] (2) The present invention utilizes a setting method in which a sliding plate, a traction plate, a fixed seat, a locking plate, a movable plate and a guide plate are matched with each other. The sliding plate drives the traction plate and the locking plate to move. The locking plate is interlaced with the fixed seat, the mounting block and the fixed column. At this time, the positions of the positioning plate and the positioning cylinder are limited, which is conducive to locking and fixing the positioning cylinder while the positioning plate vertically clamps the thread milling cutter, which is conducive to corresponding replacement of the positioning cylinder according to the diameter of different thread milling cutters;

[0042] (3) The present invention utilizes a setting method in which a threaded column, an adjusting cylinder, a connecting ring, a limiting ring, a driving ring, an auxiliary cylinder, a bottom plate, a limiting cylinder, a circular ring, a bottom ring and a series rod are matched with each other. The adjusting cylinder slides on the outside of the threaded column, and the bottom plate rotates on the outside of the adjusting cylinder through the auxiliary cylinder, the circular ring, the bottom ring and the limiting cylinder. The driving ring adjusts the height of the adjusting cylinder, which is beneficial for adjusting the supporting height of the bottom plate accordingly according to the length of the thread milling cutter to adapt to the use of thread milling cutters of different lengths.
