[0032] Two corresponding beating rods 1 are installed on the beating head, a driving mechanism is installed to drive the two groups of beating rods 1, and an oscillating mechanism is installed to limit the two groups of beating rods 1 in cooperation with the driving mechanism.

[0033] As Figure 2 , Figure 3 and Figure 4 shown, the beating head includes a connecting rod 6, which is fixedly inserted into one of the claw racks of the six-claw rack 4, and a motor slot 5 is installed at the top of the connecting rod 6. A driving mechanism is installed inside the motor slot 5. The beating head is connected to a swinging mechanism, and the two beating rods 1 on the beating head can complete synchronous left and right reciprocating beating movements. The six-claw rack 4 has multiple empty positions to adjust the positions of individual beating heads and beating rods 1.
