[0025] In specific implementation, by rotating the two threaded adjustment rings 301 in the same direction through the two oppositely arranged threaded adjustment layers 3 on the outer side of the connecting pipe 2, the first connecting rod 303 and the second connecting rod 304 are driven to fold, and a margin is reserved for the folding pipe 202, thereby adjusting the position of the connecting pipe 1, facilitating the bending connection of the utility model; after the connecting pipe 1 is connected to the heating pipe, it can be threadedly connected to the first threaded connecting rod 204 and the second threaded connecting rod 205 through the threaded connection ear 203, further supporting and shaping the bending of the folding pipe 202.
