Portion has been uniformly arranged neck；Described dropout nut is coaxially mounted to tighten nut bottom, and can be relatively rotated with tightening nut；
When need by by fastener and it is lower tightened by fastener be installed together when, tighten nut and dropout nut together to tightening
Direction rotates, and now tightens nut and dropout nut does not relatively rotate, and stops when being fastened to required Tightening moment,
Will on by fastener and it is lower fixation tightened by fastener, now the elastic baffle of elastic washer upper surface just has one to be stuck in
Tighten in a neck of nut bottom；When need by by fastener and it is lower unclamped by fastener when, individually rotation dropout spiral shell
Mother, direction of rotation is still to be rotated to the direction tightened, and now tightens nut and dropout nut relatively rotates, work as elastic washer
When the neck of nut bottom is tightened in the elastic baffle disengaging of upper surface, nut is tightened in opposite direction rotation, you can fastened on completing
Part and the lower release by fastener are acted.The quantity N for tightening the quantity M of nut bottom neck and elastic baffle on elastic washer does not have
There is the common divisor of the common divisor in addition to 1, i.e. M and N not in addition to 1.
Further, described nut bottom of tightening is provided with thread segment, and described dropout nut thread, which is connected to, to be tightened
On the thread segment of nut.
Further, described tighten has been uniformly arranged zigzag slot on nut, and described dropout nut top is laid
The sawtooth of equivalent amount is equipped with, and is corresponded with tightening the zigzag slot on nut.
Further, nut is axially arranged along tightening for the described neck for tightening nut bottom, the cushion supporting with it
The elastic baffle for enclosing upper surface is same axially arranged along elastic washer, i.e., elastic baffle is caught in neck and departs from neck vertically.
Further, the described neck for tightening nut bottom edge is tightened nut and is radially arranged, the cushion supporting with it
The elastic baffle of circle upper surface is equally radially arranged along elastic washer, i.e., elastic baffle is radially caught in neck and departs from neck.
Further, described dropout nut lower surface has been uniformly arranged disengaging buckle, and is kept off with the elasticity that is radially arranged
Plate is corresponded.
Further, described elastic washer lower surface is provided with stop cone.
Further, described elastic washer is saucer washer.
Further, the described quantity M for tightening nut bottom neck is no less than the number of elastic baffle on 7, elastic washer
Measure N and be no less than 6.
Because present invention employs above-mentioned technical proposal, the present invention has advantages below：（1）Nut is tightened by being provided with
With dropout nut, easy-to-dismount purpose while tightening locking functions is realized；（2）The present invention is simple in construction, easy to operate.
