Detailed Description

Referring to fig. 1 to 7, firstly, a tripod is erected at a point 17 to be measured, three legs 10 are extended and clamped, so that a base plate 6 is initially flat, a plumb bob 11 is hung at the lower end of a prism rod 1, a bolt 8 is loosened, an anchor ear 16 is loosened, a clamping rod 9 and the anchor ear 16 naturally droop under the action of gravity, the prism rod 1 is in an unconstrained state, a permanent magnet ball 3 is suspended in the permanent magnet hollow ball 4 under the action of the mutual repulsive force of the permanent magnet hollow ball 4 and the permanent magnet ball 3, because the integral gravity center position of the prism rod 1 is positioned below the permanent magnet ball 3, the prism rod 1 is in a natural vertical state under the action of gravity, the bolt 8 is slowly moved, a sliding plate 5 is moved, the sliding plate 5 drives the permanent magnet hollow ball 4 and the prism rod 1 to move, the tip of the plumb bob 11 of the prism rod 1 is aligned with the point 17 to be measured, the bolt 8 is tightened, and the prism rod 1 is still in the natural, the tip of the plumb bob 11 is always aligned with the point to be measured 17, and after the total station measurement is completed, the hoop 16 is used for clamping the prism rod 1 to enable the prism rod 1 to be in a locking state. Referring to fig. 3 and 4, after the bottom plate 6 is initially leveled, the bottom plate 6 and the sliding plate 5 are not in a horizontal state and form an included angle a with a horizontal plane, because the permanent magnetic ball 3 is suspended in the permanent magnetic hollow ball 4, under the weight action of the prism rod 1, the prism rod 1 and the permanent magnetic ball 3 can clockwise deflect an angle a to enable the prism rod 1 to be in a natural vertical state, if the sliding plate 5 is moved, the permanent magnetic hollow ball 4, the permanent magnetic ball 3 and the prism rod 1 can also move along with the permanent magnetic hollow ball, and the prism rod 1 can still keep the natural vertical state; referring to fig. 6, the upper external corner of the lower round hole 13 in the shape of a Chinese character 'ba' is a rounded corner, the lower round hole 13 has a minimum diameter, and the minimum diameter of the lower round hole 13 is matched with the diameter of the prism rod 1; in order to avoid that the ferrous materials are attracted or repelled by the permanent magnetic balls 3 and the permanent magnetic hollow balls 4, so that the permanent magnetic balls 3 are influenced to be freely suspended in the permanent magnetic hollow balls 4, particularly the permanent magnetic balls 3, if the permanent magnetic balls 3 in a suspended state are attracted or repelled by the peripheral ferrous materials, the natural vertical state of the permanent magnetic balls 3 is changed, and therefore all the materials of the invention are made of non-ferrous materials.
