When the hook body 101 needs to be replaced, a metal rod is used to press the buckle 305. At this time, the spring 304 is compressed at the placement hole 303. When the front end of the buckle 305 moves to the inside of the through hole 306, the hook body 101 is pulled upward to realize the disassembly of the hook body 101. Subsequently, a new hook body 101 is taken for installation;
