Background Art

The Chinese patent, application number 202322483328.0, provides a CNC machine tool fixing fixture. Through the arrangement of a bottom slide, a fixed seat, an electric telescopic rod, a mounting block, a corner support seat and a movable clamping plate, when the fixture fixes the workpiece, the workpiece is placed on the base so that the back of the workpiece contacts the second clamping pad, and then the main screw is rotated to make the movable clamping plate move toward the workpiece on the base, and the bottom slide below is driven to move at the same time during the movement. When the first clamping pad contacts the front of the workpiece, the workpiece is fixed and clamped in the fixture.
