[0012] Preferably, fixed installation grooves with side openings are provided on the fixed base plate at positions close to the four corners.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model places the special-shaped workpiece at the center of the upper surface of a fixed bottom plate, and inserts a plurality of surrounding movable rods and clamping blocks into the recessed part of the surface of the special-shaped workpiece under the action of supporting springs. Each supporting spring and movable rod can be extended and retracted individually to adapt to the irregular shape of the special-shaped workpiece, and prevents the special-shaped workpiece from shaking up and down and rotating circumferentially during the processing. It can adapt to special-shaped workpieces of different shapes, and the overall structure is simple and easy to operate, which brings convenience to production and processing.
