[0005] Further, the pushing component is a push rod, and the push rod is installed below the seat part and opposite to the tail end of the extension rod in front and back directions.

[0006] Further, fixed plates that can rotate with the backrest are installed on the joint mechanisms on both sides, and the fixed plates extend downward and are connected and fixed with the push rod.

[0007] Further, insertion feet are arranged at both ends of the push rod, and insertion holes are arranged on the fixed plates, and the push rod is inserted and fixed with the fixed plates by inserting the insertion feet into the insertion holes.

[0008] As a preferred, the push rod is a round pipe, which is made of metal pipe.

[0009] Further, the telescopic rod is installed below the seat part by a fixing seat to form a slidable structure.

[0010] Further, an end cover is arranged at the tail end of the telescopic rod, and the end cover is made of plastic.

[0011] The utility model discloses a push rod is arranged on the rear bottom surface of the seat part, and the push rod is opposite to the tail end of the telescopic rod of the foot rest, so that when the backrest is laid down, the push rod is rotated forward to push the telescopic rod forward, and the foot rest is pushed out a distance after the backrest is laid down, so that the user does not need to stretch the hand to the bottom of the seat part to pull the foot rest, thereby not only the operation is more convenient, but also more labor-saving, and the utility model is especially suitable for being used in the narrow space such as classroom.
