Abstract

The utility model relates to a flagpole retracting device, in particular to a portable ship flagpole retracting device used on a ship. The portable ship flagpole retracting device comprises a base, a shaft mounted on the base, a torsion spring connected to the shaft in a sleeved mode, a connecting seat connected with the base in a rotatable mode, and a flagpole sleeve fixed on the connecting seat. A torsion arm of the torsion spring is at least partially connected with the connecting seat fixedly. When the flagpole sleeve is in an erecting state, the torsion of the torsion spring is the smallest. In the retracting process of a flagpole, the torsion spring can generate the torsion moment counteracting part of the gravity moment all the time, and as long as a small externally-applied moment is applied by a sailor or other devices, the direction of motion of the flagpole can be controlled.
