[0037] The Y-axis floating plate 2 can reciprocate along the Y-axis direction by relying on the Y-axis floating mechanism 14, so that the bit body 10 can reciprocate along the Y-axis direction. This can adapt to the Y-axis orientation deviation of the locking accessories and products, and the bidirectional floating range is wider, which is suitable for different processing needs. In addition, the bit body 10 can always remain in a vertical state, which improves the safety of processing.
