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.

Please refer to fig. 1-3, in the embodiment of the present invention, an inner embedded and outer expanded detachable rivet includes a nail sleeve 4, a detaching device is disposed on the nail sleeve, a first nail core 2 is slidably connected in the nail sleeve 4, a nail head 1 is fixedly connected to one end of the first nail core 2, a breaking block 3 is fixedly connected to the other end of the first nail core 2, and the breaking block 3 deviates from a second nail core 5 which is fixedly connected to one side of the first nail core 2.

Referring to fig. 1, the dismounting device includes a threaded sleeve 6, the threaded sleeve 6 is screwed on the side wall of the nail sleeve 4, a pressing plate 7 is fixedly connected to the side wall of the threaded sleeve 6, the threaded sleeve 6 can be driven to rotate by rotating the pressing plate 7, and the threaded sleeve 6 is screwed on the side wall of the nail sleeve 4, so that the threaded sleeve 6 can be separated from the nail sleeve 4 by rotating the threaded sleeve 6, and the nail sleeve 4 can be taken out from the device.

Referring to fig. 3, the dismounting device includes a threaded sleeve 6, the threaded sleeve 6 is screwed on the sidewall of the nail sleeve 4, the pressing plate 7 is arranged in a hexagonal shape, and the hexagonal pressing plate 7 is more convenient for clamping the sidewall of the pressing plate 7 by using a clamp to rotate the pressing plate 7.
