An anti-reverse apparatus includes a latch capable of stopping an end sealing piece from moving reversely, and a loose switch capable of relieving a stop action by the latch on the reverse movement of the end sealing piece. Limitation of the latch on the reverse movement of the end sealing piece can be relieved by pressing the loose switch down. When the end sealing piece is detachably mounted at a near end of a sleeve in a rotating manner, the latch can stop reverse movement causing loosening of the end sealing piece and prevent air leakage or the end sealing piece from loosening from the near end of the sleeve. When the loose switch is pressed down, limitation of the latch on the reverse movement of the end sealing piece can be relieved, and the end sealing piece can be detached from the near end of the sleeve.
