Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a repair bolt convenient to cutting, includes nut 1, rectangular channel 3 has been seted up to nut 1's downside, and is provided with axis of rotation 4 on rectangular channel 3's the inner wall to axis of rotation 4 is connected with steadying board 6, and equal electrography 2 has been carved with on the both ends lower surface around nut 1's the downside, through antiskid 2, increases the frictional force on 1 downside of nut and connecting piece surface, makes nut 1 and connecting piece surface contact more firm.
A torsion spring 5 is sleeved outside the rotating shaft 4, one end of the torsion spring 5 is fixedly connected with the inner wall of the rectangular groove 3, the other end of the torsion spring 5 is fixedly connected with a stabilizing plate 6, the rotating shaft 4 is fixedly connected with both sides of the stabilizing plate 6, and the rotating shaft 4 is sleeved with a torsion spring 5, the outer side of the stabilizing plate 6 is smaller than the inner side size of the rectangular groove 3, and the rectangular groove 3 is arranged at the lower side of the nut 1, the stabilizing plate 6 and the nut 1 are arranged into a rotary embedded structure through the rotating shaft 4 and the torsion spring 5, along with the spiral descending of the stud 7, the stabilizing plate 6 is in an unfolded state through the rotating shaft 4, and along with the descending of the stud 7 until the stud is jointed with the surface of the connecting piece, the stabilizing plate 6 is connected with the connecting piece through the torsion spring 5, so that the nut 1 always maintains an upward force and the stud 7 on the underside of the nut 1 is more stably connected with the threaded hole of the coupling.
