Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a special-shaped nut comprises a hexagonal prism 1 and an auxiliary component 2 arranged outside the hexagonal prism 1, wherein a through hole is formed in the middle of the hexagonal prism 1, the auxiliary component 2 comprises an outer frame 21, the outer frame 21 is in a hollow design, the outer frame 21 is arranged outside the hexagonal prism 1, the top of the hexagonal prism 1 is penetrated through by an insert rod 22, a cylinder 23 is arranged at the position of the through hole in the middle of the hexagonal prism 1, the cylinder 23 is inserted into the through hole in the middle of the hexagonal prism 1 and is movably connected with the hexagonal prism 1, when the special-shaped nut is not used, the insert rod 22 can be firstly abutted by the cylinder 23 to avoid excessive extension under the action of the thrust component 3, the thrust component 3 is arranged on the inner side of the outer frame 21, the size of the insert rod 22 is consistent with the size capable of being inserted into a thread on a bolt, the hexagonal prism 1 can be in threaded connection with the bolt, the thrust component 3 comprises a fixing plate 31, the top of the fixing plate 31 is fixed on the inner side of the outer frame 21, the right side of the fixed plate 31 is fixed with the left side of the spring 32, the right side of the spring 32 is fixed with the left side of the sliding block 33, the top of the sliding block 33 is slidably mounted inside the outer frame 21, the right side of the sliding block 33 is hinged with one end of the supporting rod 34, the other end of the supporting rod 34 is hinged with the top of the inserted rod 22, at the moment, the spring 32 is in a compressed state, the spring 32 always gives a rightward thrust to the sliding block 33, the sliding block 33 exerts a downward thrust on the inserted rod 22 through the supporting rod 34, and when the inserted rod 22 is worn a little, the inserted rod 22 is directly pushed downwards all the time, so that the inserted rod 22 is always kept connected with a thread on a bolt, the fixed plate 31, the spring 32, the sliding block 33 and the supporting rod 34 are all provided with two groups and are all symmetrically arranged by taking the central line of the outer frame 21 as a symmetric axis, so that a more stable thrust can be exerted on the inserted rod 22, the inserted rod 22 and the thrust assembly 3 are all provided with six groups and are all spirally arranged by taking the central point of the hexagonal prism 1 as the center point, so that the bayonet 22 can be engaged with the screw thread on the bolt.

During the during operation (or during the use), when needing to use this special-shaped nut, aim at the bolt with the through-hole in the middle of hexagonal prism 1, insert the bolt in the through-hole, rotate outer frame 21, outer frame 21 drives inserted bar 22 through thrust subassembly 3 and rotates, and inserted bar 22 drives hexagonal prism 1 and rotates, and inserted bar 22 is in the screw thread on the bolt this moment, and with the state that bolt holding threaded connection, hexagonal prism 1 overlaps gradually on the bolt, and the bolt supports out cylinder 23 from the through-hole on the hexagonal prism 1.

When the special-shaped nut is used for a long time and the inserted rod 22 is worn, the sliding block 33 moves rightwards under the action of the spring 32, the sliding block 33 pushes the inserted rod 22 to move downwards through the support rod 34, and the inserted rod 22 is always connected with the thread on the bolt.
