Switch between locking；Described side lever includes upper bar and lower lateral rods, and upper bar is mutually socketed with lower lateral rods, and adjustment is between the two
Socket length, the change of side lever length can be realized；Described substrate crown center is provided with levelling tube, and pole bottom is also set
The fastening device in universal wheel direction can be fixed by being equipped with.
Substrate described in the utility model is circle.
The elastic clip for fixing instrument of surveying and mapping is provided with the top of substrate described in the utility model.
Supporting leg described in the utility model is three.
Lower lateral rods described in the utility model are hollow, and upper bar bottom is socketed in lower lateral rods, and lower lateral rods side is along vertical
Direction has been placed equidistant some hole clippings, and lower lateral rods two bottom sides are fixed with the spring that can be stretched up and down；Upper bar bottom side
The flexible clamp piece for being capable of horizontal extension is provided with, upper bar bottom is connected with the spring of lower lateral rods bottom.
The beneficial effects of the utility model are：Apparatus structure is simple, conveniently leveling.When the landform of complexity is surveyed and drawn,
It is zero that the pole of the minimum side of physical features is rotated to the angle between i.e. pole parallel with side lever and side lever around connecting shaft, makes this
The length of side leg reaches most long, and adjustment lock-screw makes the pole in the side leg be locked with connecting shaft, according to the height on ground
The position of bubble adjusts the angle between pole and side lever in other two supporting leg respectively in low and levelling tube, universal when pole bottom
Wheel it is firm land and the bubble in levelling tube positioned at it is middle when, adjustment lock-screw makes the pole in supporting leg be locked with connecting shaft
Fixed, pedestal leveling is finished, and instrument of surveying and mapping is fixed on into base-plates surface by elastic clip to be surveyed and drawn.It is of the present utility model solid
Determine the mapping that pedestal is applied to a variety of landform, the universal wheel of pole bottom can be more convenient whole adjustment process, can be effective
Raising Adjustment precision.

Embodiment
The technical solution of the utility model is described in further detail below by embodiment, and with reference to accompanying drawing.
A kind of land surveying instrument fixed pedestal, it is characterized in that：Substrate 1, supporting leg and universal wheel 4 including interconnection,
Described supporting leg includes side lever and pole 3, and side lever is fixed on the bottom of substrate 1 in certain angle of inclination, side lever with pole 3
Circular hole is provided with, side lever is connected by connecting shaft 5 through side lever with the circular hole on pole 3 with pole 3, and the bottom of pole 3 is provided with ten thousand
To wheel 4；Side lever is fixed with connecting shaft 5, and lock-screw 6 is provided between pole 3 and connecting shaft 5, can make pole 3 and connecting shaft
5 annexation between the two switches between rotation and locking；The described crown center of substrate 1 is provided with levelling tube 8, pole
3 bottoms are additionally provided with the fastening device in the direction that can fix universal wheel 4.
Substrate 1 described in the utility model is circle.
The top of substrate 1 described in the utility model is provided with the elastic clip 7 for fixing instrument of surveying and mapping.
Supporting leg described in the utility model is three.
