Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a type of clamping device, in particular, a spring group of a training rod and a force applying force (four), avoiding a spring Before the group is pressed against the spindle shaft hole, it is made from the outer shaft of the overlying spindle, and is implemented by a minimum number and minimum diameter of the spring group, so that the main (four) diameter is reduced, thereby reducing the centrifugal force of the spindle rotation, and avoiding the jitter when the spindle is actuated. This leads to inaccurate processing surfaces. Φ _ [Prior Art] [_ According to the general machine of the general machine (such as: sharp bed), a claw is attached to the spindle by a pull rod, and then the jaw is held by the clamp to drive the knife The assembled tool rotates at a high speed to perform a cutting operation on the workpiece. 0. When the second tool cuts the workpiece, the sleeve is prevented from being self-clamping/disengaging. ★ The spring set is set on the spindle (for compression or spring) With the elastic force of the spring set, the jaws are forced to clamp the blade firmly. Please refer to the US Bulletin No. 6238152, which is a kind of existing knife', and the clamping force can be clearly seen in the figure. The spring group is directly seated in the fine hole of the main wheel, and is resisted by The inner wall of the shaft hole of the main shaft, according to the retraction of the field, the compression spring group is pressed against the main shaft to cause the main shaft to wear and open; and the bearing wrapped around the main shaft is pressed and damaged. A missing; 098100430 In addition to the tool clamping device of the US Pat. No. 2,328,152, the knife must be such that the retracting device applies a force greater than the force generated by its retracting rod to the force applying rod, and continues to apply force to The tool retreat is as shown in Form No. A0101 L ^ 4th True/Total 22 pages 09820001 IX Figure]. In addition, the advance and retract strokes are extremely long, resulting in a relatively increased time for entering and retracting the tool.
