Wall perpendicularity detection mechanism

The utility model discloses a wall verticality detection mechanism, which comprises a hollow rod, a T-shaped round block, a steel wire rope, a falling block and scale marks, one end of the hollow rod is fixedly provided with the T-shaped round block, the outer side of the T-shaped round block is provided with the steel wire rope, the other end of the steel wire rope is fixedly provided with the falling block, one end of the hollow rod, which is close to the steel wire rope, is provided with the scale marks, and the other end of the hollow rod is provided with the scale marks. A guide rod is fixed in the hollow rod, two U-shaped blocks are symmetrically installed on the annular side face of the guide rod in a sliding mode, and rotating blocks are rotationally installed in the U-shaped blocks. The verticality of the wall can be judged by leaning the hollow rod against the wall and observing the included angle between the steel wire rope and the hollow rod, the push rod can move to drive the push block to move s
