The application has the feature that the neck portion is inserted and slid in the sliding groove of the shank portion, which is beneficial for adjusting the length of the tool rod according to the actual situation of the workpiece, and is beneficial for improving the adaptability of the T-slot milling cutter.

[0004] However, in actual use, the tool holder of the above-mentioned patent is provided with a tool rod, and the tool rod includes a shank part and a neck part, and the neck part is arranged on the tool holder. However, when the workpiece is actually processed, the tool holder part is more prone to wear and tear, and when replaced, it needs to be discarded together with the tool holder, which wastes resources and has a high replacement cost. T-type milling cutters that threadedly connect the tool holder and the tool rod do not usually have an anti-dislocation mechanism, and the shank is easily dislocated at the threaded connection after being vibrated, which reduces the tight and stable connection between the tool holder and the shank, and also greatly reduces the performance of the T-type milling cutter.
