The upper ends of the two support rods 11 are connected with an L-shaped mounting plate 2, and the lower ends of the two support rods 11 are connected with a bottom plate 5. Springs 12 are sleeved on the parts of the two support rods 11 between the horizontal section of the U-shaped frame 1 and the bottom plate 5;

[0025] The clamping assembly includes a fixed rod 7 fixed on the upper end surface of the L-shaped mounting plate 2. An adjusting screw 3 is screwed on the top of the fixed rod 7. One end of the adjusting screw 3 is rotationally connected with a U-shaped clamp 9 through a bearing. The two sides of the U-shaped clamp 9 are slidably inserted into the vertical section of the L-shaped mounting plate 2;

[0026] The flushing assembly includes two L-shaped spray pipes 8 fixed on the horizontal section of the L-shaped mounting plate 2.
