Mechanical product market competition ability mainly depends on the quality of products, and the quality of the products and depends on the design of the product. Jack is a simple lifting equipment. Mainly used in mines, transportation departments as vehicle repair and other lifting. The structure to be dexterous strong, agile reliable, one can carry and operation. Screw jack called mechanical jacks, is by human through vice transmission, spiral screw or nut sleeve as top heave pieces. This design is product development cycle, the key link to realize the design decisions products function and goals of the plan, structure and selection. Manufacturing methods and product operation, use and maintenance method. Design not ignore that makes the product function is not perfect, raising the cost or reliability, security is bad. Product design defects inherent shortage, difficult to take measures to offset production and use. Very few cases, namely p
