[0019] As Figures 2-4As shown, the inner side of each positioning block 5 is surrounded by an inner circle 53, and the top center of the fixing sleeve 41 is provided with a threaded hole 412, and the threaded hole 412 is provided with a positioning column 413 that is screwed with the threaded hole 412 and can penetrate the inner circle 53 downward and cooperate with the inner wall of the inner circle 43. When the fixing sleeve is screwed to the outer side of the positioning block, the top of the fixing sleeve is screwed with the positioning column, the positioning column enters the fixing sleeve along the thread and extends into the inner circle, and the side wall of the inner circle abuts against the side wall of the positioning column. Each positioning block can be limited by the positioning column to avoid the inward movement of the positioning block when the fixing sleeve is screwed with the positioning block, which causes the fixing sleeve to be unable to be fixed with the positioning block, ensures the structural stability of the connection between the fixing sleeve and the positioning block, and the outer end of the positioning column 413 is provided with a limiting block 414 outside the fixing sleeve 41. The limiting block is provided to avoid the positioning column from being screwed too much into the positioning block and being difficult to take out, and affecting the movement of the positioning block.

The above-mentioned elastic element is made of a material with elastic deformation ability (such as silica gel, rubber, etc.). When the fixing sleeve is installed on the positioning block, the positioning block is driven to move towards the surrounding center. At this time, the elastic element is contracted. Because the rubber sleeve on the side wall of the positioning part exists, when the center through hole of the saw blade is not completely stable, when the positioning block is driven to move, the surrounding outer diameter of the positioning block becomes smaller, the saw blade falls on the table top of the support table in a stable state, and at the same time, the positioning block is returned to the original position by the rebounding force of the elastic element. The surrounding outer diameter of the positioning block returns to the same as the center through hole of the saw blade. At this time, the center through hole of the saw blade is just clamped on the rubber sleeve of the positioning part, forming reliable positioning of the saw blade.
