Patent attributes
A water injection rack base for a mast is formed of two semi-bases connected together by hinges, at the top surfaces of the two semi-bases being provided 1-2 water injection holes, on the joint face of the two semi-bases and on the central position being provided semi-cylindrical concaves, thereby forming holes on the top surface for inserting a mast when the two semi-bases are pulled open. This invention is of foldable-type, when in use, it can be easily pulled open, without need of being connected by bolts. The water injection hole is concealed, thereby preventing dusts and litters from entering into the bases, and making this invention novel in appearance. This invention has water discharge holes with easy water discharge, thus reducing labour intensity for workers.
