1. A quick coupler for coupling with pipes, comprising:
a top ring, a bottom ring, and fasteners;
wherein the top ring and the bottom ring are configured to be assembled together; the top ring is provided with a top ring groove, and the bottom ring is provided with a bottom ring groove; the fasteners are loosely or tightly connected to the top ring and the bottom ring, so that the top ring and the bottom ring are assembled together as a whole; in a tight state, the top ring groove of the top ring and the bottom ring groove of the bottom ring are assembled to form an annular groove for fixing pipes,
wherein the top ring is an arc member, and further comprises a top ring left fixing head and a top ring right fixing head; the top ring left fixing head and the top ring right fixing head are positioned on two ends of the top ring respectively; the top ring groove is positioned on an arc inner side of the top ring; the bottom ring is an arc member, and further comprises a bottom ring left fixing head and a bottom ring right fixing head, the bottom ring left fixing head and the bottom ring right fixing head are on two ends of the bottom ring respectively; the bottom ring groove is positioned on an arc inner side of the bottom ring; the fasteners comprise a left fastener and a right fastener, the left fastener is loosely or tightly connected to the top ring left fixing head and the bottom ring left fixing head, and the right fastener is loosely or tightly connected to the top ring right fixing head and the bottom ring right fixing head,
wherein the top ring further comprises a top ring left part, a top ring middle part and a top ring right part; and the bottom ring further comprises a bottom ring left part, a bottom ring middle part and a bottom ring right part,
wherein the top ring left part comprises a top ring left activity head protruding upwards from an upper end of the top ring left part, and the top ring right part comprises a top ring right activity head protruding upwards from an upper end of the top ring right part,
wherein the bottom ring left part comprises a bottom ring left activity head protruding downwards from a lower end of the bottom ring left part, and the bottom ring right part comprises a bottom ring right activity head protruding downwards from a lower end of the bottom ring right part,
wherein the top ring middle part is provided with a top ring middle groove positioned on an arc inner side of the top ring middle part, the top ring left part is provided with a top ring left groove positioned on an arc inner side of the top ring left part, the top ring right part is provided with a top ring right groove positioned on an arc inner side of the top ring right part,
wherein the bottom ring middle part is provided with a bottom ring middle groove on an arc inner side of the bottom ring middle part, the bottom ring left part is provided with a bottom ring left groove positioned on an arc inner side of the bottom ring left part, the bottom ring right part is provided with a bottom ring right groove positioned on an arc inner side of the bottom ring right part,
wherein when the left fastener and the right fastener are fastened into the tight state, the top ring middle part, the top ring left part and the top ring right part of the top ring are tightly jointed in a manner that adjacent ends thereof come in contact with each other, the bottom ring middle part, the bottom ring left part and the bottom ring right part of the bottom ring are tightly jointed in a manner that adjacent ends thereof come in contact with each other, so as to allow the top ring middle groove of the top ring middle part, the top ring left groove of the top ring left part and the top ring right groove of the top ring right part to be assembled to form the top ring groove of the top ring and to allow the bottom ring middle groove of the bottom ring middle part, the bottom ring left groove of the bottom ring left part and the bottom ring right groove of the bottom ring right part to be assembled to form the bottom ring groove of the bottom ring, adjacent ends of the top ring left part and bottom ring left part come in contact with each other, and adjacent ends of the top ring right part and bottom ring right part come in contact with each other, such that the top ring groove of the top ring and the bottom ring groove of the bottom ring form a continual sealed annular groove.
