As the further improvement of the utility model, it is circumferentially with some grooves in the lateral surface upper edge of the insertion section of said chuck body, can increase the frictional force between chuck body and the product, helps being fixedly clamped of product.
As the further improvement of the utility model, said tension force groove is six, and is symmetrically distributed on the lateral surface of insertion section of said chuck body.
As the further improvement of the utility model, the holding part of said clamping body and empty avoiding portion are all cylindrical.
As the further improvement of the utility model, said tension force groove extends in the empty avoiding portion of said chuck body.
Further improvement as the utility model; Said tensioner one end is cylindrical; And be evenly equipped with screw thread on its lateral surface; The end that the other end of this tensioner closes on this cylindrical end forms a vertical contact-making surface, between the vertical contact-making surface of this tensioner and said chuck body, is provided with back-up ring.
The beneficial effect of the utility model is: the endoporus through expand in this type spring chuck and processed product carries out clamping and positioning; And then be fixed to this spring chuck on the lathe; A clamping can be realized the processing of product two sides, saves the clamping time, promotes efficient; And guarantee processing dimension and position degree to promote product quality.
