The structure consists of an upper bracket, a lower bracket, a machine tool base, a guide sleeve, a lead screw, a support guide column and other parts. After long-term use, this mechanism will increase the gap between the support guide column and the blank, which is prone to vibration and loose clamping. When processing holes, it is easy to cause the surface of the hole to be rough, and in severe cases, the drill bit will be damaged. When replacing blanks of different specifications, the position of the lead screw and the support guide column must be adjusted appropriately, and the adjustment time is long and it is difficult to adjust, resulting in low production efficiency.
