The function of adjusting the clamping force according to the aperture size required to be processed is realized. The larger the diameter of the drill 220, the larger the aperture of the ball valve cartridge 100 is processed; the smaller the diameter of the drill 220, the smaller the aperture of the ball valve core 100 is, thereby improving the application range of the valve core processing fixture.
