摘要

The strengthening connection head (1) for plastic umbrellas or sunshades has a concave groove (14) running along it on whose sides are situated two parallel holes (11,12) and a connecting piece (13) on the end, into which a third piece can be pushed and fastened. In the plastic groove is a small metal plate (2) containing two holes (21,22) whose size and position corresponds to the holes on the plastic groove. The first bolt(91) on the first hole of the plastic groove is pushed through the first hole on the end of the first connecting piece as well as through the first hole in the metal plate. The same happens for the second bolt(92) in the second holes, making a moveable connection.
