<p>A connection structure of a system bracket is provided. Said structure comprises pluralities of the connection seats (30), pluralities of the fasteners (50) and pluralities of the positioning pins (60). The pluralities of the connection seats surrounding horizontally an upright stanchion (10) of a tubular bracket are fixed in manner of corresponding to the axis of the upright stanchion and erectly on the outer wall of the upright stanchion. The fastener pivoting by means of an inserting pin on the end of a draw rod (20) of the system bracket includes a first side wall and a second side wall. The positioning pin through the connection seat and the fastener at the same time is distinguished according to their functions into a holding section and a traversing section, wherein two locking parts protrudes from the free end of said traversing section and their central connection line runs parallel with the axis of the holding section. After the traversing section runs in turn through the fastener and the connection seat, said two locking parts can be locked on the end surface of the second side wall of the fastener to avoid that the positioning pin disengages and falls because of an improper outside force. Said structure can be assembled conveniently, combined stably and has a high safety factor.</p> |
