Abstract
Based on current domestic and international market research and found that most of the existing jack can not meet the user's consumption concept. If you choose the low price of the product, in performance it can not be guaranteed ;if you choose the choice of quality products, most users find it difficult to accept the high price.
This design mainly introduced based on the traditional jack, through the design of mechanical structure, thereby overcoming the traditional jack that have poor safety performance, mobile is not flexible and can not meet the quality requirements of users, such as shortcomings. Considered the cost, the use of occasions, and the convenience of the user operation, identified four horizontal jack design. Through theoretical calculations, checking strength, principle and performance analysis, the design of a detailed description. At the same time in the design process, there are some issues to be addressed, these problems one by one of the detailed analysis. Finally regulate the use of the jack that, do not comply with instructions it can easily lead to security problems.
