[0003] Many milling machine processes today rely on operators to accurately place the workpiece on the workbench and secure it with a fixture. This process involves precise positioning and clamping adjustments of the workpiece, which usually takes a long time. In addition, the fixture screws need to be unscrewed after the processing is completed, which further increases the operation steps and time costs. Utility Model Content

[0004] Based on the above background, the purpose of the present invention is to provide a movable fixture for milling machine processing that can accurately place and fix materials and is easy to operate, so as to solve the problems described in the background technology.
