Multifunctional retractable wrench

The utility model discloses a multifunctional retractable wrench, which comprises a handle, the sleeve head and the open spanner head are arranged at the first end and the second end of the handle respectively and used for clamping a bolt or a nut. According to the scheme, an open-end wrench and a sleeve type wrench are combined into a whole, fastening work of nuts on the horizontal plane or the vertical plane can be achieved, the problem that a traditional wrench cannot be used in a narrow space in a wire coiling box of a current transformer or a voltage transformer is particularly solved, it can be guaranteed that the nuts on binding posts are fastened to be qualified, and the working efficiency is improved. Therefore, the working efficiency is greatly improved, and the safety and the stability of a power grid are ensured. 本实用新型公开了一种多功能可收缩式扳手，包括：手柄；分别设置于手柄的第一端和第二端，且均用于夹持螺栓或螺母的套筒头和开口扳头。在本方案中，将开口扳手与套筒式扳手合二为一，可以实现无论是水平面还是垂直面螺母的紧固工作，特别解决了诸如电流互感器、电压互感器盘线盒内的狭窄空间传统扳手无法施展的难题，可确保接线柱上的螺母紧固合格，不会出现接线松动甚至开路的情况，极大地提高了工作效
