[0008] A further configuration of the present invention is that the elastic coefficient of the first elastic member is greater than the elastic coefficient of the second elastic member.

[0009] The utility model with the above-mentioned characteristics: after the special-shaped sealing ring is sent to the pressing chamber by the feeding device, the pressing cylinder drives the pressing rod and then drives the reaming assembly to move toward the special-shaped sealing ring, the reaming head corresponds to the inner hole of the special-shaped sealing ring and abuts against the special-shaped sealing ring, and the special-shaped sealing ring continues to move upward. When the special-shaped sealing ring abuts against the movable limit block, the reaming head expands the inner hole of the special-shaped sealing ring so that the special-shaped sealing ring is sleeved on the reaming head, and the pressing cylinder continues to apply an upward force. Since the elastic coefficient of the first elastic member is greater than the elastic coefficient of the second elastic member, the reaming head pushes open the movable limit block, and the movable limit block shrinks to the mounting hole, and the reaming head drives the special-shaped sealing ring to continue to move upward until it abuts against the mounting position, the pressing cylinder continues to output pressure, the reaming head shrinks into the mounting groove, and the base pushes the special-shaped sealing ring to separate from the reaming head so that the special-shaped sealing ring enters the mounting position of the filter, thereby completing the installation of the special-shaped sealing ring.

[0010] A further configuration of the utility model is that: an inclined surface is provided at one end of the movable limit block relative to the first elastic member, and when the movable limit block is not subjected to force, the inclined surface faces the bottom of the pressing cavity.
