Limiting device with drawing fixing function for construction cost

The utility model discloses a limiting device with a drawing fixing function for engineering cost, which belongs to the technical field of engineering cost and comprises two mounting plates, one surfaces, close to each other, of the two mounting plates are respectively sleeved with a rotating shaft through bearings, the outer wall of the rotating shaft is sleeved with a placing plate, and the right end of the rotating shaft is sleeved with a rotating gear. According to the limiting device with the drawing fixing function for the construction cost, by arranging a rotating shaft, a rotating gear, a toothed plate, a threaded rod and a threaded cylinder, when a worker uses the device, a drawing is fixed to the front face of a containing plate firstly, so that the threaded rod moves up and down on the inner wall of the threaded cylinder, and the threaded rod pushes the toothed plate to move up and down; and the rotating gear drives a placing plate to rotate through a rotating shaft, so that the angle between the p
