In order to make the spool be heated uniformly, the upper clamp 1 and the lower clamp 2 are arranged in the form of semicircular buckles, after the upper buckle 11 and the lower buckle 21 are buckled, the spool can be wrapped in, and the semicircular heating holes are formed in the heating modules 16 and 26 so that the spool can be completely wrapped by the two heating modules 16 and 26 for heating.

When the outer sleeve of the line pipe is cut, the opening and closing angle of the upper clamp 1 is adjusted through the opening and closing adjuster 4, so that the inner line pipe is prevented from being damaged.

Then the upper and lower clamps are buckled. Then, the driving motors in the upper connecting pipe 12 and the lower connecting pipe 22 are started, so that the upper rack 17 in the clamping groove 13 drives the upper transmission arc 51 to rotate forward, the lower rack 28 in the clamping groove 25 drives the lower transmission arc to rotate reversely, and because the upper positioning arc 52 and the lower positioning arc are clamped with the limiting sliding groove 54 through the limiting sliding block 61, the upper transmission arc 51 can rotate forward relative to the upper positioning arc 52 through the cooperation between the upper sliding bar 511 and the upper sliding groove 521, and similarly, the lower transmission arc rotates reversely relative to the lower positioning arc.
