[0048] The heat exchange chamber 100 is internally connected to a reciprocating screw 2 803, and a bevel gear 4 804 is fixedly connected to the side of the reciprocating screw 2 803. The bevel gear 4 804 meshes with the bevel gear 3 802. When the bevel gear 3 802 rotates, it drives the bevel gear 4 804 to rotate, which in turn drives the reciprocating screw 2 803 fixedly connected to it to rotate.

[0049] The outer side of the reciprocating screw rod two 803 is connected with the sliding plate two 805 through setting thread, the sliding plate two 805 is located at the inside position of the heat exchange bin 100, and is in sliding connection with the heat exchange bin 100, and the side surface of the sliding plate two 805 is fixedly connected with the processing brush one 806.

When the oil in the hydraulic chamber two 906 flows to the side close to the arc-shaped rod 907 due to extrusion, the arc-shaped rod 907 in sliding connection with the hydraulic chamber two 906 through setting a piston is driven to move out of the hydraulic chamber two 906.
