The double-axis motor is arranged on the connecting beam 3. Both output ends of the double-axis motor are connected to the gear transmission member. The other end of the gear transmission member is connected to a group of rotating seats 302 at the side end of the connecting beam 3. The two groups of chain transmission members are respectively arranged between the multiple groups of rotating seats 302 on both sides of the connecting beam 3. The two groups of gear transmission members are driven to rotate by the double-axis motor, thereby driving the rotating seats 302 connected to the gear transmission members to rotate. The rotating seats 302 rotate through the corresponding chain transmission members, thereby causing the multiple groups of rotating seats 302 on both sides of the connecting beam 3 to rotate simultaneously. A plurality of rotating seats 302 on both sides of the connecting beam 3 are installed on both sides of the connecting beam 3. An L-shaped seat 5 is assembled, and a slide seat 501 is installed at the bottom end of the slitting fork 502. The slide seat 501 is slidably connected to the L-shaped seat 5.
