[0020] As shown in Figure 5As shown, the elastic support 1 comprises coaxially and oppositely arranged upper and lower fixing rings 101 and 102, the upper fixing ring 101 is located at the opening of the cover body, and the lower fixing ring 102 is located at the bottom of the cover body, and the elastic spiral steel 103 is coaxially arranged between the upper and lower fixing rings 101 and 102.
[0021] The elastic spiral steel 103 forms a spring-like structure, which can compress and release the cover body by the elastic force of the elastic spiral steel 103. When it needs to be stored, it is completely compressed, and it will not be completely compressed in the natural state because it has a certain elasticity. At the same time, the elastic spiral steel 103 limits the outside of the cover body, and the upper and lower fixing rings 101 and 102 limit the top and bottom of the cover body respectively, preventing deformation or collapse from affecting the collection effect of high-altitude welding, and having certain wind resistance and anti-deformation ability.
[0022] The hanging piece 3 is fixed along the outer side of the upper fixing ring 101 at equal intervals around the shaft, and the top of the hanging piece 3 is flush with the top of the upper fixing ring 101, so that the top of the cover body is flat. It is convenient to be hung in the air to cooperate with high-altitude welding to complete collection, and can also be used as a subsequent conductive member. The flatness ensures that the cover body can be as flat as possible after being inverted to be flush with the flat ground to form a closed environment.
