When clamping, the holding tube on one side of a movable limit frame is tangent to the limiting tube on the other side of the other movable limit frame, which can improve the connection stability of adjacent movable limit frames, so that multiple movable limit frames can be continuously connected. By clamping multiple foam boards at the same time, multiple foam boards can be cut synchronously, which greatly improves the cutting efficiency of the foam boards. After the cutting is completed, the telescopic end of the telescopic cylinder is retracted, and the movable limit frames are pushed open during the process of the telescopic spring recovering its deformation, so as to facilitate the removal of the cut foam boards.
