[0028] The anti-skid protrusions 1102 are integrally formed between the upper rotatable half ring 1101 and the anti-skid protrusions 1102, and can prevent slipping, so that the staff can rotate the upper rotatable half ring 1101 by the anti-skid protrusions 1102. The clamping groove blocks 1103 are inside the annular sliding groove 16, so that the clamping groove blocks 1103 rotate inside the annular sliding groove 16 when the upper rotatable half ring 1101 rotates, so that the upper rotatable half ring 1101 can rotate. The two thread plates 1104 are spliced to form a cylinder, which is screw-connected between the connecting thread groove 14 and the first spliced PE booster pipe 1. The butt joint guide columns 1105 are inserted into the butt joint grooves 1107.

When the push rod 105 exits the range of the intercommunication frame 104, the intercommunication frame 104 communicates with the through groove 15. At this time, the powder hot melt adhesive falls on the thread of the thread plate 1104. The powder hot melt adhesive continuously fills in the gap between the thread plate 1104 and the connecting thread groove 14 with the connection of the thread plate 1104 and the connecting thread groove 14. When the first spliced PE booster pipe 1 and the second spliced PE booster pipe 11 are spliced, the silica gel heating sheet 108 can be started to heat the heating ring 101 and melt the powder hot melt adhesive filled in the gap between the thread plate 1104 and the connecting thread groove 14. Since the hot melt adhesive is in powder form, the hot melt adhesive can be quickly fused, and the thread plate 1104 and the first spliced PE booster pipe 1 are tightly and stably connected by the thread engagement.
