我们在生产实践中,结合工作需要,试制了多用可调螺母扳手,并应用于实践中收到了较好的效果。此工具制作简便,使用方便(见图1)具有许多优点:(1)装上防脱套,使螺母不易脱开;(2)调节方便迅速,现有扳手靠螺丝调节,不仅费劲,且费时间,而它只用母指推动便可适应大小不同螺母的拆装,(3)能按不同范围较准确地夹上螺母,(4)一头可当扳手,一头可当起子使用;(5)比现有活动 We in the production practice, combined with the work needs, trial production of a variety of adjustable nut wrench, and applied to practice received good results. The utility model has the advantages of simple manufacture and convenient use (see FIG. 1), which has many advantages: (1) the anti-shedding sleeve is installed so that the nut can not be easily disengaged; (2) the adjustment is convenient and swift; the existing wrench is adjusted by screws; Time, and it can only be used to promote the thumb nut disassembly and disassembly of different sizes of nuts, (3) according to different ranges more accurately clip nut, (4) a wrench can be used as a screwdriver; Than existing activities
