[0009] An adjusting screw is rotatably arranged at the edge position of the circular support plate, a circular limit pressing plate is arranged outside the vertical rod above the rotating sleeve, an adjusting threaded cylinder is arranged on the circular limit pressing plate, and the adjusting threaded cylinder is arranged outside the adjusting screw;

[0010] The adjusting screw is vertically arranged on the annular supporting plate. Rotating the adjusting screw can drive the annular limiting pressing plate to move up and down. A rubber gasket is arranged on the bottom surface of the annular limiting pressing plate.

[0011] The specific features of the present utility model further include:

[0012] Through holes are formed in the side walls on both sides of the lifting and adjusting sleeve. A plurality of through holes are equidistantly formed on the vertical rod. A limiting bolt is arranged in the limiting hole and the corresponding through hole.

[0013] The base includes a barrel with an open top. A threaded installation sleeve is arranged at the middle position of the bottom of the barrel. The vertical rod is arranged in the threaded installation sleeve.

[0014] An installation stud is arranged at the bottom end of the vertical rod. The installation stud is arranged in the threaded installation sleeve.

[0015] Sand and gravel are arranged inside the barrel. Preferably, a warning slogan is arranged on the surface of the barrel.

[0016] When installing the monitoring point, install the vertical rod in the threaded installation sleeve in the barrel. Then, put sand and gravel or stones into the barrel to form a load-bearing support. Then, adjust the lifting and adjusting sleeve to a specified height and fix it with the installation stud. Then, rotate the rotating sleeve to rotate the marker to a position convenient for observation. Keep the position of the rotating sleeve unchanged. Rotate the adjusting screw to drive the annular limiting pressing plate to move downwards and press the rotating sleeve to complete the installation.

[0017] The beneficial effects of the present utility model are: simple structure, convenient to use, the whole is convenient to move and assemble, and at the same time, it is convenient to adjust the position of the marker. BRIEF DESCRIPTION OF THE DRAWINGS
