摘要

The suspension has a boom platform-cut area that is suspended by a tension rod at a central fixing point with a plate. A standing surface is attached to a diameter of a boom by a joint and is adjusted at an end of the tension rod by a thread. The fixing point is set by using a through hole of the trunk and insertion of a threaded rod. The standing surface is composed of a U-support, a base retainer and a wooden board.
