The invention discloses an improved construction scaffold. The improved construction scaffold comprises a main frame, an auxiliary frame, an upper pressing rod and a lower pressing rod. A first open slot penetrating from left to right is formed in the main frame. The upper pressing rod is rotationally installed on the upper middle portion of the first open slot through a rotating rod. A distance regulating groove is formed in the lower pressing rod. A distance regulating rod is moveably installed in the distance regulating groove and is fixedly installed on the lower portion of the first open slot. One end of the upper pressing rod and one end of the lower pressing rod are rotationally connected through another rotating rod. An upper arm lever and a lower arm lever are fixedly arranged at the other end of the upper pressing rod and the other end of the lower pressing rod respectively. An upper pressure block and a lower pressure block are fixedly installed at the tail end of the upper arm lever and the tail end of the lower arm lever respectively. The upper pressure block and the lower pressure block are each internally provided with an arc cavity with a cavity mouth facing outside, and each arc cavity penetrates from top to bottom. A round block is fixedly installed at the lower end of the main frame, and a main extrusion arm is fixedly arranged in the middle of the bottom of the round block.
