Tube body two 7 and tube body three 8 are respectively slidably arranged on the outside of the two groups of floating adjustment baffles 10.

[0022] Further improvement, such as Figure 2 As shown: the regulator 4 is composed of a motor 12, a rotating wheel 13 and a toggle block 14. The motor 12 is installed at the upper end of the arc plate 2 and the power output end is connected to the rotating wheel 13. The rotating wheel 13 is built into the notch 5. The toggle block 14 is fixed to the edge of the rotating wheel 13. The rotating wheel 13 is driven to rotate by the motor 12, and the rotating wheel 13 drives the toggle block 14 to rotate during the rotation process.

[0023] Further improvement, such as Figure 2 As shown: the toggle block 14 is fan-shaped as a whole and the width of one end is smaller than the width of the other end. The outer end of the toggle block 14 contacts the lower end of the arc plate 1.
