The structure comprises a positioning post 10 and an engaging member 20. The positioning post and the engaging member are disposed on the two frame portions B1, B2 respectively. The positioning post 10 includes a spring 12 biassed stopping block 13. When the positioning post 10 is inserted into the engaging member 20, it deflects the stopping block 13 against the spring 12 to restrict the positioning post in the engaging member, so that the two frame portions B1, B2 can be coupled, uncoupling being prevented by the block 13 protruding from one side of the post 10.. When the stopping block 13 is pressed, the positioning post 10 can disengage from the engaging member 20. |
