[0009] Compared with the prior art, the utility model has the following advantages: the long condition milling fixture can effectively solve the problems existing in traditional fixtures when processing long strip workpieces by adding components such as L-shaped downward pressure fixing plate, telescopic mechanism and workpiece back support plate. Specifically, the fixture can provide more uniform support for the workpiece when clamping through the workpiece back support plate, avoiding deformation of the workpiece during the milling process, thereby ensuring processing accuracy and stability, and improving the milling effect and processing quality. Through the telescopic mechanism, the fixture can adapt to workpieces of different lengths, and installation and adjustment are also more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
