Improvement structure of outer box member of air injector

摘要

The present invention discloses an improved structure of the air injector outer box member. The air injector is accommodated and placed in an outer box member assembled from the first box member and the second box member, and when the first box member and the second box member are to be combined with each other, the positioning pin of the second box member is removed. 1 penetrates and penetrates the through-hole of the box member and causes the outer end head of the positioning pin to enter the inclined horn wall at the end of the hollow circular column of the first box member and to hang on the stepped portion of the inclined horn wall end. In order to separate the first box member and the second box member combined with each other, the detachable rod member enters the through hole through the first box member and contacts the positioning pin of the second box member to position it. The outer end head of the pin slides out of the stepped portion of the inclined horn-shaped wall end, and the outer end head of the positioning pin is pushed by the removable rod member By further entering the inclined horn wall, the first box member and the second box member combined with each other can be immediately separated.
