[0002] With the development of large-scale equipment manufacturing industry, the market has higher and higher performance requirements for CNC machine tools. Single-function processing machine tools with only a single processing and production function are increasingly unable to meet the processing needs of complex workpieces, and are being replaced by composite processing machine tools.

[0003] The Chinese patent application number CN202320519497.2 discloses a special machine tool for milling and drilling, including a machine tool base, a lifting platform is provided on the front outer surface of the machine tool base, a movable slide is provided in the middle of the machine tool base, a slide rail is provided on the upper outer surface of the machine tool base, a processing table is provided on the upper outer surface of the slide rail, a controller is provided on one side outer surface of the machine tool base, a motor is provided on the upper outer surface of the lifting platform, a machine head is provided on the lower outer surface of the lifting platform, guide grooves are provided on both sides of the outer surface of the processing table, and a sliding block is provided in the middle of the guide groove. The special machine tool for milling and drilling described in the utility model can be fixed in position by tightening the screw rod when in use, and the workpiece can be clamped and fixed by the limit plate on the vertical rod. By moving the sliding block in the guide groove, workpieces of different sizes can be fixed, and the fixing and disassembly of the workpiece can be convenient, which can improve the efficiency of work when in use. However, when the above device is actually used to fix the workpiece, the workpiece is fixed by the limit plate driven by the spring. The fixation by the squeezing force of the spring alone is unstable and the workpiece is prone to movement, which affects the processing quality of the workpiece.

[0004] In view of this, the present utility model is proposed. Utility Model Content
