The application relates to the technical field of sports auxiliary machines, and discloses a portable ground dotting device for
orienteering, which comprises a mounting driving mechanism, an adjusting
energy storage mechanism and a knocking mechanism are fixedly connected in the mounting driving mechanism, a
signal receiver is fixedly connected to the upper end of the mounting driving mechanism, the mounting driving mechanism comprises a sleeve rod, a sliding rod one is clamped and connected to the inner upper portion of the sleeve rod, and a triangular driving frame is fixedly connected to the inner middle portion of a triangular wind driving cover. Through cooperation of the mounting driving mechanism, the adjusting
energy storage mechanism and the knocking mechanism,
athletes can quickly find the dotting device to perform dotting according to the
impact sound in the wild, the
athletes cannot quickly find the dotting device to perform dotting due to the shielding of trees and sundries in the wild is avoided, when the
wind force is large, the triangular wind driving cover rotates faster, the
athletes can judge the current
wind force level according to the shape and rotating speed of the triangular wind driving cover, the size and density of the knocking sound, and the
physical ability is reasonably distributed.
