Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-5, the high-low span extension plumb bob paying-off tool comprises a support 1, a first adjustable balance support 2 and a second adjustable balance support 3 are arranged below the support 1, the first adjustable balance support 2 is arranged at the tail of the support 1, the second adjustable balance support 3 is arranged in the middle of the support 1, an adjusting rod is arranged on the first adjustable balance support 2, two adjusting rods are arranged on the second adjustable balance support 3, and the connecting lines of the three adjusting rods form a triangle. When in use, the whole bracket 1 can be in a horizontal position by adjusting the heights of the three adjusting rods. A vertical and horizontal leveling bubble 4 is arranged on the top surface of the bracket 1, and whether the bracket 1 is in a horizontal state or not is judged by using the vertical and horizontal leveling bubble 4.

Be provided with steel ruler 5 at the side of support 1, the steel ruler 5 that the side set up can make things convenient for constructor to acquire the distance that support 1 removed fast.
