The key concept of the technical scheme is as follows: the spliced pole can make the swivel nut body be connected more firmly with the self tapping screw rod, and the groove of breaking simultaneously makes the swivel nut body fix behind the inside of the screw hole that the fixing base was reserved easily, is convenient for break the spliced pole.
Furthermore, grooving is respectively arranged on two sides of the inner wall of the top end of the screw sleeve body, and an elastic gasket is arranged on the outer wall of the bottom of the screw sleeve body.
Furthermore, a coating layer is arranged outside the screw sleeve body, and an anti-corrosion layer is arranged outside the coating layer.
The utility model has the beneficial effects that:
1. through the spliced pole and the rupture groove that set up, the spliced pole can make the swivel nut body be connected more firmly with the self tapping screw rod, and the rupture groove makes the swivel nut body fix the inside back at the screw hole that the fixing base reserved easily simultaneously, is convenient for break the spliced pole.
2. Through grooving and the elastic washer that sets up, the grooving can with the couple joint on the extracting tool, and the quick detachable swivel nut body of this mode not only dismantles the convenience to the swivel nut body, does not harm the swivel nut body moreover, this swivel nut body simple structure of while, production is convenient.

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.
Please refer to fig. 1 to 3 simultaneously, a conical barrel for a blind hole includes a barrel body 1, the barrel body 1 is distributed in a conical structure, a connection column 2 is arranged at the bottom end of the barrel body 1, and the connection column 2 is integrally connected with the barrel body, two breaking grooves 3 are formed at the connection position of the barrel body 1 and the connection column 2, and an included angle between two edges of the breaking grooves 3 is sixty degrees, so as to facilitate breaking the connection column 2.
As apparent from the above description, the present invention has the following advantageous effects: the connecting column 2 can enable the thread insert body 1 to be connected with the self-tapping screw more firmly, and meanwhile, the breaking groove 3 enables the thread insert body 1 to be fixed in the rear of the inside of a threaded hole reserved in the fixing seat easily, so that the connecting column 2 is convenient to break.
Further, grooving 5 has all been seted up to the inner wall both sides on 1 top of swivel nut body, and is provided with spring washer 4 on the outer wall of 1 bottom of swivel nut body, can be convenient for dismantle swivel nut body 1 from the fixing base through grooving 5.
Furthermore, the coating layer 6 is arranged outside the screw sleeve body 1, and the anti-corrosion layer 7 is arranged outside the coating layer 6, so that the screw sleeve body 1 can be prevented from being corroded, and the service life of the screw sleeve body 1 is prolonged.
