Preferably, the cross wire center point is provided with a micro small hole.
Preferably, the outer side wall of the fixing rod is provided with threads.
Preferably, the inner diameter of the expansion pipe is matched with the radius of the fixed rod, and the outer side wall of the expansion pipe is provided with three identical symmetrical openings.
Preferably, the device also comprises a hook arranged beside the control point, wherein the hook is U-shaped, so that the hanging ball can be conveniently folded and placed.
The beneficial effects of the utility model are as follows: the utility model greatly helps the top plate of the empty area to embed the measurement control point, and effectively solves the problem that the monitoring point at the top plate is not easy to center. The device is convenient to embed, the cost of manufacturing materials is low, and the layout method is simple, so that the accuracy and the working efficiency of measuring data are improved. And the utility model is more convenient and efficient in field operation.
