[0003] Publication (announcement) number CN221337431U discloses an automatic tool for mounting sound-absorbing cotton and a quick plug, but the tool is only suitable for scenarios where there is no shape requirement for sound-absorbing cotton, because when the tool is used, the posture of the sound-absorbing cotton after falling into the pressing hole from the guide groove cannot be controlled. For example, when sintered cotton is used as sound-absorbing cotton, the sound-absorbing cotton made of sintered cotton is a column with a certain hardness. If the guide groove is a column, the column-shaped sound-absorbing cotton will stand straight in the pressing hole after falling down, and the end of the column-shaped sound-absorbing cotton will not face the air pipe opening, but the side wall of the column-shaped sound-absorbing cotton will face the air pipe opening, which cannot be inserted. If the guide groove is widened, the posture of the column-shaped sound-absorbing cotton after falling down from the wide groove is not necessarily horizontal with the end facing the air pipe opening, and the column-shaped sound-absorbing cotton may stand straight after falling down and still stand straight in the pressing hole, or lean against the side wall of the pressing hole.
