[0002] In the field of metal processing, especially in precision machining, the slotting and gear hobbing process is a key and complex task. Traditional slotting and gear hobbing power tool holders often have problems such as cumbersome manual operation, low processing efficiency, and difficulty in guaranteeing precision.

[0003] During the processing of traditional power tool holders, manual tool retracting and feeding operations are usually required, which not only increases the labor intensity of operators but also easily causes processing errors due to human factors. For this reason, we propose an automatic tool retracting reciprocating slotting and gear hobbing power tool holder. By driving a driving device to drive a driving shaft and a driving gear to rotate, a driven gear is then forced to drive a column to move inside a ring groove, realizing the automatic tool retracting and reciprocating slotting and gear hobbing functions of a moving seat and a main shaft.
