When the single frame 1 is rotated, the scraper 2 607 is driven to rotate by the third rotating rod 604, so that it rotates along with the rotation of the single frame 1 2, so as to realize the cleaning and auxiliary support of the single frame 1 2 and the single frame 2 4 after the rotation angle, and the suction cup 1 610 sucks the outer surface of the single frame 1 2 to ensure that the single frame 2 does not slide during welding, thereby ensuring the welding quality, and at the same time, the fourth rotating rod 609 is used to enable it to rotate along with the rotation of the single frame 2, so as to ensure the sucking effect of the suction cup 1 610.
