[0003] Chinese patent publication number CN214236614U discloses a milling machine fixture, including a worktable with several supports fixedly connected to it. Each support has an axial positioning device on its upper part and a radial positioning block on its support. The axial positioning device includes a support column, a pressure plate, and an adjusting rod. One end of the support column abuts against the upper part of the support, and the other end is fixedly connected to one end of the pressure plate. The pressure plate has a waist-shaped groove in its middle. One end of the adjusting rod is installed in the waist-shaped groove, and the other end of the adjusting rod is installed in the T-shaped groove on the upper part of the support. The radial positioning block includes a fixing part and a positioning part. The fixing part is fixedly connected to the upper part of the worktable, and the positioning part is provided with several positioning screws arranged in the radial direction.
