Threaded rods 1 are provided at both ends of the support rod 9. One end of the threaded rod 1 is screwed with a threaded sleeve 2. One end of the threaded sleeve 2 is provided with a rubber foot sleeve 3. One side of the middle of the support rod 9 is installed with a rotating rod 7 through a bearing 6. One end of the rotating rod 7 is installed with an argon gas protection cover 4. An argon gas inlet pipe 5 is installed on the argon gas protection cover 4.
