Aiming at the problems that the copper tube assembly has poor protection effect and is not easy to disassemble, the following scheme is proposed, which includes a first copper tube and a second copper tube. A clamping sleeve is fixed on the outer surface of the first copper tube, and four symmetrically distributed clamping grooves are opened inside the clamping sleeve. An iron block is fixed on one side of the clamping groove. A fixing sleeve is fixed on the outer surface of the second copper tube. Four plug rods that cooperate with the clamping grooves are fixed on the side of the fixing sleeve close to the clamping sleeve, and a magnet that cooperates with the iron block is fixed on the top of the plug rod. A threaded sleeve is slidably connected to the other side of the fixing sleeve. In the utility model, the threaded sleeve rotates, and the slider drives the sliding rod to slide upward with the extrusion of the push block, prompting the clamping block to clamp in the clamping groove, thereby achieving multiple protection effects of the copper tube assembly. When the threaded sleeve is rotated in the reverse direction, the clamping block releases the clamping state of the clamping groove, thereby realizing the function of easy disassembly of the copper tube assembly.
