The positioning elastic member 376 is preferably a spring. In practical application, when the upper cutter shaft 30 drives the second upper cutter shaft bearing seat 33 to move leftwards until the circular cutter 31 is positioned at the cutter attaching position, the positioning elastic piece 376 is compressed, and when the upper cutter shaft 30 drives the second upper cutter shaft bearing seat 33 to move rightwards until the circular cutter 31 returns to the cutter retracting position, the positioning elastic piece 376 can return to a natural state.

The positioning block 3752 and the limiting block 3732 are arranged to limit rightward movement of the second upper cutter shaft bearing seat 33.

The second gauge 61 can measure the distance of the first adjusting seat 36 moving back and forth, and can intuitively display the moving amount of the first adjusting seat 36, so that the adjustment is convenient.
