Description of the invention: [Technical field to which the invention pertains] The present invention relates to the improvement of the structure of the claw base of a main shaft, in particular to a plurality of spacer blocks protruding from the end of the claw seat, and at the claw seat The ring seat is provided with an elastic ring for the claw flap structure of the claw to be movably engaged. [Prior Art] A conventional high-speed spindle processing machine is provided with a shaft ^ in the main shaft of the processing machine, and a ring groove is further recessed at the front end of the shaft, wherein the shaft hole is provided with a tie rod structure, the cutter The front end of the pull rod is provided with a - claw seat, and the plurality of claws are external to the claw seat; the cutter rod is controlled by a hydraulic cylinder or a pneumatic cylinder to control the front and rear displacement; when the face f is moved forward by the cutter rod The front end of the claw falls into the ring groove to drive the L to be closed, so that the cutter can smoothly place the knife seat of the tool into the opening. When the tool rod is moved backward, the front end of the claw can be along the edge of the ring groove. The action of the clamping is 'when the front end of the claw is completely disengaged and the knife seat is tightened completely; the claw system of the conventional technique is wrapped around the periphery of the claw seat, and the square (4) is fixed by the claw red. _ When the claw seat controls its position, the direction of the claw is not subject to any restriction. 'When the spindle rotates at a high speed, because the spindle is driven', the relative slippage between the claws on the _ claw base changes, _ easy to cause the spindle Counterweight, shaking: this operation will be shaken Into the spindle ^ ‘damage good, production. .瑕& too much, serious when more [invention] Invented, the technical problem to be solved: The structure of the private claw broach does not have a radial limit structure, and the relative sliding phenomenon occurs between the high speed rotation of the spindle and the rotation of the spindle. Irregular sway occurs when the spindle is running high; the condition of this operation is light
