Abstract
PURPOSE: To permit a surveying pole to be stably and accurately placed on a measuring point where no spider can be used by attaching a centripetal member having a conic hole to be fitted with the tapered part at the end of a surveying pole and a through hole to connect with its end to a flat holding member through a fitting hole.
CONSTITUTION: In a centripetal member 20 made of a material such as brass, an inner hole 24 to be fitted with the tapered part at the end of a surveying pole 2 and a center hole 22 penetrating through a cylindrical base end part 21 are made so as to have the identical center axis. A plurality of fitting holes 12 are made in a holding member 10 having a flat sitting surface 11. Into the hole 12, the centripetal member 20 is inserted and secured by using, e.g., screws. For example, when a measuring point A is on the edge of a gutter, the holding member 10 is placed on the upper side of the gutter, then the measuring point A and the center of the hole 22 of the centripetal member 20 are aligned, and the pole 2 (or mirror) is attached to the centripetal member 20. Therefore, this permits the pole 2 to be stably and accurately placed on a measuring point where no spider can be used.
