[0007] By adopting the above technical solution, the measuring rod is placed between the steel bars to be measured, and the fixed hook and the movable clamp rod are adjusted to appropriate positions, the fixed hook is pressed against one of the steel bars, and the position of the movable clamp rod is adjusted by the connecting piece so that the movable clamp rod is pressed against another adjacent steel bar; since the fixed hook is located at the zero scale of the scale mark, that is, it serves as the reference point for measurement, the position of the movable clamp rod will reflect the spacing between adjacent steel bars, and the distance between adjacent steel bars can be directly read through the scale on the scale mark; the device of the present application is simple and easy to use, and can quickly and accurately locate and measure the spacing between steel bars without the need for complex tools or techniques. Through the design of the fixed hook and the movable clamp rod, the user can easily adjust and read the measurement results, thereby improving work efficiency.

[0008] In a specific feasible implementation scheme, a slot is formed between the fixed hook and the measuring rod on a side away from the movable clamping rod; among the adjacent steel bars, one of the steel bars is stuck in the slot, and the other steel bar rests against a side of the movable clamping rod away from the fixed hook.
