The utility model relates to a nut all-purpose elastator, which belongs to the field of electrical tools and equipment. The technical scheme of the invention is as follows: the tightener is composed of a connecting seat, several locking shafts, nut sleeves and positioning pins; the upper part of the connecting seat is provided with an inner quadrangular upper cylinder head for connecting with the protruding quadrangular head of the bolt wrench, and a pinhole penetrating the fastening pin shaft is made; the lower part is provided with a connecting block with the same number of locking shafts and a lower cylinder head inserted into the nut sleeve; and the end of the locking shaft is provided with and connected. A part of the locking block is milled on the opposite side of the lower cylinder and the connecting block; the upper end of the nut sleeve is provided with a central hole penetrating the lower cylinder head of the connecting seat and a side hole penetrating the cylinder body of the locking shaft; the lower end is provided with a concave hexagonal cylinder larger than the standard sleeper nut, and the screw hole for installing the positioning pin is produced on the cylinder. The beneficial effects are: quick tightening of nuts, high production efficiency, strong adaptability, novel conception, reasonable design, simple structure, convenient operation, safety and reliability.

技术介绍
螺纹联接是利用螺纹零件构成的可拆式联接,型式繁多、拆装方便、工作可靠、加工容易、成本低廉,在国民经济各领域应用十分广泛。螺纹可分为内螺纹和外螺纹,螺纹联接就是将内螺纹和外螺纹相配合,螺纹联接具有良好的自锁性,用螺栓扳手将其紧固后能牢固地将两个零件联接在一起。将螺栓锁紧或拆卸螺母所用的各种型式的螺栓扳手,有手动的、电动的、气动的、液动的、内燃机驱动的,还有锂电池驱动的等等。不论哪种螺栓扳手,都需要通过套筒才能将螺母锁紧在螺栓上或者将螺母从螺栓上松开。套筒是由一套多个带凹六角孔的圆筒并配备手柄、接杆等附件组成,这些凹六角孔都是固定的。在实际对螺栓上的螺母进行锁紧或松开作业中,往往出现六角螺母因磨损、锈蚀或磕碰而不能嵌入套筒的凹六角形孔内的情形,以至于一套多个套筒都不适合套入六角螺母。比如,铁路轨枕上的六角螺母由于雨露霜雪长年累月的侵蚀、列车淋下的洗漱水、冲厕水的腐蚀等自然与人为因素的共同作用,轨枕上的六角螺母锈蚀严重,而且往往是不规则的单边锈蚀。因而螺栓扳手头部的凹六角形圆筒嵌入时,不能紧密地箍住六 ...
