When the supporting plate is not stretched, the positioning plate is hinged at the edge of the positioning platform. When the supporting plate is opened, the supporting plate is positioned on the plane of the mounting platform by the positioning plate. The structure is simple and convenient for fixing.

Both ends of the support plate are arc-shaped.

The utility model has the following advantages:

1. In the utility model, the pillars are made into square or circular opposite sides as facades, and grooves are vertically opened on the opposite sides, and a rotatable support plate is arranged in the groove. When in use, the rotating support plate and the installation The platform is flush (that is, basically parallel or on the same level), and is positioned by the positioning device. The bolt is rotated in the threaded through hole of the support plate to install the measuring instrument, and the loss of the bolt can be prevented, so it can be installed on the installation platform. It is convenient to install multiple surveying instruments on the same plane to measure geological landforms, and only need to carry one measuring bracket.

2. The positioning device of the present utility model includes a positioning plate, one end of the positioning plate is hinged to the installation platform, and its hinge point is located between the fixing bolt and the pin shaft, and the other end of the positioning plate forms a hook shape; There is a positioning pin, and the positioning pin is located between the fixing bolt and the pin shaft; the positioning plate is rotated and hooked to the positioning pin for positioning the support plate, and the positioning plate is perpendicular to the opening direction of the groove. When the supporting plate is not stretched, the positioning plate is hinged at the edge of the positioning platform. When the supporting plate is opened, the supporting plate is positioned on the plane of the mounting platform by the positioning plate. The structure is simple and convenient for fixing.
