A clamping and adjusting mechanism for the semicircular clamping frame 17 is provided on the frame 15, and the clamping and adjusting mechanism includes a rotating seat 19 and a threaded rod 20. A rotating seat 19 is fixedly installed on the top side of the semicircular clamping frame 17, and one end of the threaded rod 20 is rotatably installed on the top side of the rotating seat 19, and the other end of the threaded rod 20 is threadedly penetrated to the outside of the frame 15. Through the clamping and adjusting mechanism, multiple third rubber rollers 18 on the semicircular clamping frame 17 are pressed against the oil pipeline body 2, so as to clamp and fix the oil pipeline body 2; multiple third rubber rollers 18 on the inner wall of the semicircular clamping frame 17 are respectively rotatably installed A third rubber roller 18 is overlapped on the oil pipeline body 2. A plurality of slots 21 are respectively provided on the circular plate 13. A bottom frame 22 is fixedly installed on one side of the first semicircular pipeline seat 8.

When half of the oil pipeline body 2 is welded, the staff adjusts the movable plate 24 downward to slide downward in the movable groove 23, so that the spring 25 is subjected to force to produce deformation and compression, The plug plate 26 is driven to disengage from the corresponding slot 21, and then the bottom rod 28 is rotated to make the bottom rod 28 fit on the bottom side of the corresponding limit plate 27, so as to fix the position of the plug plate 26, and repeat the operation to disengage the other plug plate 26 from the corresponding slot 21. Then, the staff puts their hands on the surface of the oil pipeline body 2 and rotates the oil pipeline body 2. At this time, the clamped oil pipeline body 2 is driven to rotate between the supporting rubber roller 14, the multiple first rubber rollers 10, the multiple second rubber rollers 11 and the multiple third rubber rollers 18, so as to turn over and rotate the oil pipeline body 2. When the appropriate position is reached, the two movable plates 24 are adjusted to make the two plug plates 26 respectively inserted in the corresponding slots 21 on the two circular plates 13 after rotation, so as to fix the position of the oil pipeline body 2 after turning over and rotating, and reduce the situation that the oil pipeline body 2 continues to rotate, so as to facilitate the staff to continue welding the other half of the oil pipeline body 2, and the operation is very simple and fast.
