One end of the square core shaft 6 with the pin hole 64 is arranged in the insertion groove, and the pin 10 passes through the eccentric pin hole 84 and the pin hole 64. The square core shaft 6 and the pressure wheel 8 are rotatably connected through the pin 10; the handle 9 is connected to the side plate 83 of the pressure wheel 8. When the beating arm 3 is working, it extends horizontally, and the handle 9 drives the clamping wheel 8 to rotate. The clamping wheel 8 rotates around the eccentric pin shaft hole 84 and drives the annular toothed belt 71 of the toothed clamping pad 7 to wedge into the toothed end surface 36 of the connecting tube 34 to keep the beating arm 3 from rotating; when the beating arm 3 is not working, the handle 9 drives the clamping wheel 8 to rotate in the opposite direction, and the clamping wheel 8 no longer presses the toothed clamping pad 7, and the annular toothed belt 71 of the toothed clamping pad 7 disengages from the toothed end surface 36 of the connecting tube 34, and the beating arm 3 can rotate and droop.

[0035] One end of the square core shaft 6 is a square shaft 61 and the other end is a circular shaft 62. The circular shaft 62 is provided with a swing hole 63 that cooperates with the swing arm 4 without mutual rotation. The circular shaft 62 is arranged in the connecting tube 34.
