Wall-attached support of lifting scaffold

The utility model provides a wall-attached support of a lifting scaffold. The wall-attached support comprises an attached base and a front-end safety assembly. The attachment base comprises two oppositely-arranged vertical rods, two transverse rods are connected to the upper portion between the two oppositely-arranged vertical rods, a connecting groove allowing a through-wall bolt to penetrate through is formed between the two transverse rods, the width of the connecting groove allows the two through-wall bolts to penetrate through in parallel, a transverse plate is arranged below the two transverse rods, and the transverse plate is connected with the two transverse rods. Connecting holes allowing the through-wall bolts to penetrate through for installation are formed in the transverse plate, the problem of the connecting mode under the complex wall surface working condition is mainly solved, under the conventional working condition, transverse through-wall connection can be achieved through the first through
