Universal socket spanner

The invention relates to the field of manual tools, and discloses a universal socket spanner. The universal socket spanner comprises a handle, a maximum sleeve, an additional sleeve, a minimum sleeve, an additional sleeve spring and a minimum sleeve spring. In the prior art, compared with a common spanner, an existing socket spanner has no monkey design similar to the common spanner and capable of adapting to multiple nut specifications, so that the convenience and flexibility are poorer that those of the common spanner. A single sleeve of the universal socket spanner can adapt to two or more nut specifications, the problem is effectively solved, and the convenience and flexibility of the socket spanner are improved. 本发明涉及手工工具领域，公开了种万用套筒扳手，包括手柄、最大套筒、附加套筒、最小套筒、附加套筒弹簧和最小套筒弹簧。在现有技术中，目前套筒扳手与普通扳手相比，套筒扳手没有类似于普通扳手那样可适应多种螺母规格的活口设计，以至于在便捷性和灵活性相对于普通扳手较差。万用套筒扳手的单个套筒能适应两种或两种以上的螺母规格，有效解决了上述问题，提高了套筒扳手的便捷性和灵活性。
