The saw blade is wound on the outer diameter of the upper pulley and the lower pulley. The upper pulley and the lower pulley are connected with a drive motor for driving the rotation of the saw blade. A cantilever beam is arranged above the workbench and is mounted on the bed body. Two pressing plates are arranged on the cantilever beam and are slidably mounted on the cantilever beam through a sliding plate mounted on the cantilever beam. A hydraulic cylinder is arranged on the sliding plate to drive the pressing plates to move up and down. Two guide rods are arranged on both sides of the hydraulic cylinder and are fixed to the sliding plate. The pressing plates can be adjusted in position according to the size of the workpiece to press and fix workpieces of different sizes and shapes, thereby facilitating the sawing and processing of the workpieces and improving the processing quality.

When the clamping force is too large, it will damage the workpiece. When the clamping force is too small, it cannot guarantee the stability of the workpiece during processing. The actual application effect is not good. In order to solve the above problems, an adjustable pressing device of vertical sawing machine is urgently needed. SUMMARY
