We often meet situations like unable using jacks of both sides due to too large charge when using socket. In order to solve this problem, we use the principle of stretching straw on socket. Our idea is to make every jack on the socket as a single unit, linking by the extensible structure of straw. The using processes are as follows: If you can not use socket when meeting the above situation, stretch the socket units (providing multiple perspectives) to provide using space. This is a good solution for traditional socket’s problem.
