S3: Pull the base 1 to move the outer adjusting plate 23 towards the inner end of the sealing plate 22. When the outer adjusting plate 23 approaches the bracket 21, rotate the butterfly bolt 12 again to adjust the gap between the outer adjusting plate 23 and the bracket 21 to ensure that the outer adjusting plate 23 does not contact the bracket 21 when it passes through the bracket 21. S4: Repeat step S3 until the outer adjustment piece 23 passes the last bracket 21 on the sealing piece 22. When the triangular tip 25 of the engine baffle contacts the horn groove 104 of the base 1, it indicates that the outer adjustment piece 23 is installed in place. S5: After assembly, rotate the wing bolt 12 to remove the assembly tool from clamping the outer adjusting piece 23, then rotate the two handles 13 until their indicator marks point to the working status release mark on the base 1, and remove the assembly tool after completely releasing the outer adjusting piece 23.
