Abstract: The present invention 10 discloses a universal lug wrench that can be used by ordinary people to loosen and fasten the lug nuts 12 on automobile tires 14 without undue strain on the users part. This is made possible by a supporting adjustment stand 16 and the longer arm 18 of the wrench 20. The present invention 10 is also easy to disassemble and store and also versatile as the sockets 22, 23 for the lug nuts 12 of different sizes can easily be interchanged. The purpose of the wrench 20 is to exert a torque on a lug nut 12 at the socket 22 end and around the axis by pressing the handle end 21. The improved wrench of the present invention 10 eliminates the unwanted torque generated by a conventional wrench 24. The present invention 10 has an extension 54 for the sockets 22 that are inserted into the adjustable clamp 56 and provides a pivoting point for the wrench 20. Various sockets 22, 23 can be interchangeably used for lug nuts 12 of different sizes.

Abstract translation: 本发明10公开了一种通用的凸耳扳手，其可以由普通人使用，以便将凸耳螺母12松动并紧固在汽车轮胎14上，而不会对使用者部件造成不必要的压力。 这可以通过支撑调节支架16和扳手20的长臂18来实现。本发明10也容易拆卸和储存并且也是通用的，因为用于不同尺寸的凸缘螺母12的插座22,23可以容易地 互换。 扳手20的目的是通过按压手柄端部21在插座22端部并且绕轴线在凸耳螺母12上施加扭矩。本发明10的改进的扳手消除了由常规扳手24产生的不期望的扭矩 本发明10具有用于插座22的延伸部分54，其插入到可调节夹具56中，并提供用于扳手20的枢转点。各种插座22,23可以互换地用于不同尺寸的凸耳螺母12。
