Considering that two springs may become loose after long-time use, the loosening of the springs may cause the unstable clamping of the clamping device to slide from the pipeline body 1, in order to reinforce the clamping device, two nuts 17 are movably connected to two ends of the round rod 16, the two nuts 17 are movably connected to the outer walls of the left clamping plate 15 and the right clamping plate 14 on the round rod 16, the left clamping plate 15 and the right clamping plate 14 are connected through the round rod 16, the left clamping plate 15 and the right clamping plate 14 are fixed by screwing the two nuts 17 on the round rod 16, and the loosening of the left spring 13 and the right spring 12 is prevented from causing the unstable clamping of the clamping device to slide from the pipeline body 1, so that the clamping device is reinforced.
