[0005] The centering rod auxiliary sleeve is made of aluminum, has a thickness of 2mm, is a 5cm*5cm cube, and has a hollow center with a diameter of 3cm for inserting the centering rod.

[0006] The transverse rod and the vertical rod are both aluminum tubes with a diameter of 3 mm. The length of the upper transverse rod is 3 cm, the length of the lower transverse rod is 5 cm, and the length of the vertical rod is 6 cm.

[0007] The measuring point clamp device is an aluminum ring with a thickness of 2 mm and a diameter of 3 cm, which is welded to the transverse rod of the centering rod auxiliary bracket.

[0008] The fixing bolt is an adjustable screw.

[0009] This new device features an ingenious design and simple operation, requiring minimal processing materials and technical expertise. During use, the centering rod is inserted into the hollow centering rod auxiliary sleeve, secured in the center position using washers and fixing bolts. The measuring point clamp assembly then slides the rod vertically over the measuring point, placing the rod's lower end at the center of the cross. This device allows for self-installation and quick and easy disassembly, improving the accuracy of the centering rod, reducing human centering errors during measurement, and enhancing work efficiency, all while ensuring accurate construction measurements.
