[0024] Specifically, in use, the bottom plate 1 is placed at the bottom of two gas pipes to be installed, then one of the gas pipes is lifted and placed between the second clamping plate 11 and the first clamping plate 10 on the left side, and similarly, the other gas pipe on the right side is lifted and placed between the second clamping plate 11 and the first clamping plate 10 on the right side. At this time, attention should be paid that the gas pipes have their own weight, so the T-shaped sliding block 25 will slide downward in the T-shaped sliding groove 19, and the rack 23 will also slide downward.
