A backing plate is fixedly arranged at the bottom of the installation groove. A saw blade positioning column is fixedly arranged on the upper surface of the backing plate. A disassembly groove is formed at the top of the installation groove. A moving plate is arranged inside the disassembly groove. Two connecting rods are fixedly arranged on the lower surface of the moving plate. A limiting clamping plate and a limiting clamping sleeve are respectively and fixedly arranged at the lower ends of the two connecting rods. A screw rod is rotatably arranged on the side wall of the chuck body. One end of the screw rod extends into the disassembly groove and is in threaded connection with the middle part of the moving plate, and the other end of the screw rod extends outside the chuck body and is fixedly provided with a knob.
[0007] Preferably, a saw blade is inserted into the installation groove, and a saw blade positioning hole on the saw blade is inserted and matched with the saw blade positioning column.
[0008] Preferably, the limiting clamping sleeve is inserted and matched with the upper end of the saw blade positioning column.
[0009] Preferably, the peripheral side walls of the moving plate are in sliding contact with the peripheral side walls of the disassembly groove.

[0012] Compared with the prior art, the utility model provides a multifunctional saw blade clamping device, which has the following beneficial effects:
[0013] In this multifunctional saw blade clamping device, after the saw blade is inserted into the installation groove and inserted and matched with the positioning post, the knob is rotated manually by hand to make the screw rotate. During the rotation of the screw, the moving plate is driven to move downward in a spiral manner, so that the moving plate drives the connecting rod, the limiting clamping plate and the limiting clamping sleeve to move downward until the limiting clamping plate presses the saw blade against the surface of the backing plate. At the same time, the limiting clamping sleeve is inserted into the upper end of the saw blade positioning post. At this time, the saw blade can be firmly clamped inside the chuck body, and the saw blade will not fall off from the saw blade positioning post. By adopting a double clamping structure, the cutting use effect of the saw blade is improved.
