[0014] see figure 1 Shown: a double telescopic column at the bottom of a large cylinder with a guide ring passing through the weld seam, which is composed of the outer cylinder 1, the middle cylinder 2 and the live column 3 as the main force-bearing rods. The guide ring 4 is installed on the middle cylinder and the live column is equipped with Guide ring 5. The inside of the outer cylinder bottom is made hollow, and the middle cylinder bottom is placed in its cavity to the maximum extent; at the same time, the live column bottom is placed in the middle cylinder bottom to the maximum extent, so that the three have a greater degree of overlap. Set the bypass safety valve interface 6 within the range of 40°-45° beside the outer cylinder to install the safety valve.
