The utility model provides a fastener is moved in antidetonation antiskid, please refer to 1-2, including first fastener portion 1, the last downside of first fastener portion 1 all is provided with second fastener portion 2, install sectional type screw rod 3 between first fastener portion 1 and the second fastener portion 2, sectional type screw rod 3 includes positive thread portion 301, anti-thread portion 302 and smooth portion 303, positive thread portion 301 accomplishes the butt joint with first fastener portion 1 in its bottom, smooth portion 303 fixed connection is between positive thread portion 301 and anti-thread portion 302, the screw direction of positive thread portion 301 and anti-thread portion 302 is opposite, positive thread portion 301 threaded connection has fastening nut 4, anti-thread portion 302 threaded connection has confrontation nut 5.

Further, referring to fig. 1-2, the length of the smooth portion 303 is greater than the thickness of the fastening nut 4, so that the fastening nut 4 can smoothly pass through the smooth portion 303 after twisting through the reverse threaded portion 302, and the twisting butt joint with the normal threaded portion 301 is completed, thereby avoiding the problem that the fastening nut 4 cannot reversely rotate due to the fact that a part of the top of the fastening nut 4 is still at the position of the reverse threaded portion 302 and the fastening nut 4 cannot be in the position of the reverse threaded portion 302 and is in the position of the reverse threaded portion 301, and after the fastening nut 4 and the counter nut 5 are in the butt joint with the segmented screw 3, a third of the smooth portion 303 extends into the smooth portion 303.

Further, please refer to fig. 1, an end wall of the first fastening part 1 is provided with a mounting groove 101, a bottom end of the regular thread portion 301 is fixedly connected with a rotating shaft 6, the rotating shaft 6 rotates in the mounting groove 101 corresponding to the rotating shaft, an end wall of the second fastening part 2 is provided with a butt-joint groove 201, the sectional screw 3 is driven by the rotation of the rotating shaft 6 to butt-joint with the butt-joint groove 201, the butt-joint groove 201 is provided on the second fastening part 2, and the sectional screw 3 is rotatably connected with the first fastening part 1 through the rotating shaft 6, by such a design, a pair of bolts between the first fastening part 1 and the second fastening part 2 does not need to be loosened completely, but only needs to be loosened, the first fastening part 1 and the second fastening part 2 can be detached from the workpiece, and the convenience in detaching and installing the fastener on the workpiece is improved.

Further, referring to fig. 1, a gasket is sleeved on the sectional screw 3 at the upper side of the butt-joint groove 201 to increase the contact area between the fastening nut 4 and the second fastening part 2, so as to protect the second fastening part 2.

Further, referring to fig. 1, the fastening nut 4 and the opposing nut 5 are both provided with anti-slip threads on the upper and lower end surfaces thereof, so as to further improve the effect of the axial rotation of the fastening nut 4 driving the opposing nut 5 to rotate synchronously.

The utility model discloses a theory of operation and use flow:

in use, referring to fig. 1-2, in the same way as the fastening method of the conventional fastener on a workpiece, an operator attaches the first fastener portion 1 and the second fastener portion 2 to the upper and lower end surfaces of the workpiece, and then screws the fastening nut 4 on the segmented screw rod 3 to fasten the first fastener portion 1 and the second fastener portion 2 to the workpiece, but different from the above, because the segmented screw rod 3 is split into three parts, namely, a positive thread portion 301, a negative thread portion 302 and a smooth portion 303, and the thread directions of the positive thread portion 301 and the negative thread portion 302 are opposite, the fastening nut 4 should be opposite in the twisting directions on the negative thread portion 302 and the positive thread portion 301, and after the fastening nut 4 is twisted to pass through the negative thread portion 302 and the smooth portion 303, the operator can be in butt joint with the positive thread portion 301 by reversely twisting, and finally fasten the first fastener portion 1 and the second fastener portion 2, and after fastening is completed, the anti-twisting nut 5 is in butt joint with the negative thread portion 302, and at this time, the anti-twisting nut 4 cannot be rotated but only in contact with the fastening nut portion 302, so that the end surface of the fastening nut 4 is tightly installed;

in the actual use process of the installed fastener, when the fastening nut 4 and the segmented screw 3 have an axial loosening tendency, the installed fastener inevitably drives the counterforce nut 5 which is located on the upper side of the fastening nut and is in close contact with the fastening nut 4 to rotate in the same direction, but because the thread directions of the positive thread part 301 where the fastening nut 4 is located and the reverse thread part 302 where the counterforce nut 5 is located are completely opposite, the fastening nut 4 is further pressed by the counterforce nut 5 rotating under the driving of the fastening nut 4, and the rotating tendency of the fastening nut 4 is offset, so that the axial loosening of the fastening nut 4 in the segmented screw 3 is resisted.

The utility model discloses a with the sectional type screw rod 3 structure that traditional nut structure design is constituteed by normal thread portion 301, anti-thread portion 302 and smooth portion 303, and with the screw direction design of normal thread portion 301 and anti-thread portion 302 opposite, through the different tendency of rotating of counter nut 5 that is located on fastening nut 4 on the normal thread portion 301 and on the anti-thread portion 302 when vibrations offset the not hard up trend of axial vibrations of fastening nut 4 and sectional type screw rod 3, compare in traditional fastener, anti-seismic performance obtains promoting.
