[0003] In the application number 202221088894.0, a measuring and laying-out device for water conservancy project construction is mentioned, including a mobile base, and the mobile base is provided with a laying-out roller, a stabilizing roller and a feeding roller in sequence according to the laying-out direction. The stabilizing roller is provided with an adaptation component for driving the stabilizing roller to slide back and forth, and the adaptation component includes a driving motor, a sliding rod and a slider. The output end of the driving motor is connected to a screw rod, and the screw rod and the sliding rod both pass through the interior of the slider. The stabilizing roller is located on the upper side of the slider, and an adjustment component for adjusting the tension of the rope is provided on one side of the slider. The adjustment component includes an adjustment rod rotatably arranged on the slider, and an adjustment shaft is provided on the adjustment rod. The middle part of the adjustment rod is rotatably connected to a hydraulic rod.

[0004] The pay-off roller, stabilizing roller and feed roller are used to pay-off the water conservancy project. The stabilizing roller can guide the pay-off, and the adjusting shaft can support and transport the measuring line. However, when releasing the measuring line, if the staff makes an error in operation, the pulling direction of the measuring line will shift during the pulling process, causing the measuring line to shift on the adjusting shaft or the stabilizing roller. As the adjusting shaft and the stabilizing roller rotate, the measuring line will fall off the stabilizing roller and the adjusting shaft, causing the measuring line to get stuck. As a result, the stabilizing roller is not convenient for limiting the measuring line as required, and there are certain limitations. Utility Model Content
