Furthermore, rubber sealing sheets are respectively arranged on the contact surfaces of the closing sheets.
By adopting the technical scheme, the closing pieces can be matched with each other and the inserting port is sealed under the action of the rubber sealing piece, so that dust or moisture is prevented from entering.
Furthermore, the number of the closing pieces is two.
By adopting the technical scheme, the two closing pieces are arranged and are respectively arranged on the left side and the right side or the upper side and the lower side of the inserting port, so that the closing pieces are convenient to use.
Furthermore, the inserting protective sleeve is provided with a circle of sealing convex edge at the inserting port, and the sealing convex edge is arranged on the outer side of the closing sheet.
By adopting the technical scheme, the gap between the closing sheet and the inserting port can be blocked by the sealing convex edge, so that the closing sheet and the inserting port are sealed, and dust or moisture is prevented from entering.
Further, sealed chimb can be dismantled with the grafting protective sheath and be connected, be equipped with the joint piece on the sealed chimb, the grafting protective sheath corresponds the joint piece and is equipped with the mounting groove.
Adopt above-mentioned technical scheme, set up like this and can make sealed chimb pass through the block of joint piece and mounting groove and can dismantle with the grafting protective sheath and be connected, not only simple structure, convenient connection do not influence the dismouting of closing the piece moreover.
