Abstract: An assembling connector structure including a multidirection connector having multiple square hollow insertion columns, multiple square connecting tubes and multiple substantially U-shaped leaf springs. Each face of each insertion column is formed with two through holes and each end of each connecting tube is formed with two through holes. Each leaf spring is disposed with a long and a short engaging boss. The long boss has upper and lower engaging recesses. When assembled, the leaf spring is first inserted into and engaged with the insertion column. Then the connecting tube is fitted around the insertion column with the through holes of the connecting tube aligned with the through holes of the insertion column, so that the bosses of the leaf spring pass through the aligned through holes to bound outside the connecting tube to assemble the connector structure into a solid frame assembly having multiple square frames.
