Here, the rolling and support of the auxiliary wheels not only facilitates the formation of a closed-loop weld, but also maintains the balance of the welded parts, thereby ensuring that the weld is formed evenly and improving the welding quality.

[0011] Preferably, the extension portion is annular or rectangular and is arranged parallel to the first waterproof membrane and / or the second waterproof membrane.

[0012] Furthermore, there are two auxiliary wheels and they are symmetrically arranged about a center line of the connecting end.
