An L-shaped connecting rod 607 is fixed at the bottom of the movable block 605. An arc plate 608 is fixed at one end of the L-shaped connecting rod 607 away from the movable block 605. There are two groups of arc plates 608, and the two groups of arc plates 608 are symmetrically arranged with the center line of the handle 2 in the vertical direction as the symmetry axis. A limiting rod 609 is fixed on the inner side of the arc plate 608. The limiting rod 609 passes through the side wall of the handle 2 and is slidably connected at the penetration. There are two groups of limiting rods 609 and limiting holes 610, and the two groups of limiting rods 609 and limiting holes 610 are arranged with the center line of the handle 2 in the vertical direction as the symmetry axis. The center in the vertical direction is symmetrically arranged as the axis of symmetry. When the saw blade 1 needs to be installed, the rotating block 602 can be rotated forward to squeeze the movable rod 606, so that the rotating block 602 squeezes the movable rod 606 and rotates at the hinge. The two groups of movable blocks 605 can be squeezed away from each other by the movable rod 606, and the L-shaped connecting rod 607 can be driven to move, so that the arc plate 608 drives the limit rod 609 to move out of the installation hole 4, and the installation block 5 can be extended into the installation hole 4 to align the limit hole 610 with the limit rod 609. By loosening the rotating block 602, because the spring 604 is in a contracted state, the spring 604 can drive the rotation The block 602 is reversed, so that the rotating block 602 pulls the movable rod 606, and the moving block 605 drives the L-shaped connecting rod 607 to move, so that the two sets of arc plates 608 are close to each other, and the limiting rod 609 is driven to extend into the limiting hole 610, so that the saw blade 1 can be fixed on the handle 2, which is convenient for the staff to operate.
