AI Technical Summary
Technical Problem
Existing milling cutter holders may experience loosening of locking components due to vibration during prolonged use, posing a safety hazard.
Method used
It adopts a stepped threaded through-hole design, with a lower locking bolt, a stop and an upper locking bolt in the inner cavity. The threads turn in opposite directions. Combined with the stop and thrust spring, it ensures that the bolt is tightened and does not loosen. The regular polygonal structure and anti-rotation boss prevent rotational misalignment.
Benefits of technology
It enables rapid locking of the milling cutter holder, preventing loosening caused by vibration and improving safety and stability.

Abstract
This utility model relates to the field of milling technology, specifically a milling cutter holder that facilitates quick locking. It includes a cutter holder and a base. A mating shaft is fixed on the cutter holder. Threads are formed at the upper and lower ends of the inner wall of the threaded through hole, with opposite thread directions. The lower end of the lower locking bolt is engaged with and adapted to the inner cavity of the locking groove. A wrench hole is formed through the middle of the upper locking bolt, and a retaining ring is fixed to the inner wall of the wrench hole. A pressure-bearing column moves through the retaining ring. A receiving groove is formed on the upper surface of the lower locking bolt. The wrench hole, the stop, and the receiving groove are all regular polygons. The beneficial effect is that the lower locking bolt can lock and fix the mating shaft, while the stop, under the action of the thrust spring, is simultaneously engaged in the inner cavity at the lower end of the wrench hole and the inner cavity at the upper end of the receiving groove. Therefore, the upper and lower locking bolts are mutually locked through the stop, thereby preventing the possibility of loosening due to vibration.
