Since power is transmitted between the second drive shaft 515 and the second tool shaft 528 via a synchronous belt, the split structure of link B 524 facilitates the installation of the synchronous belt. Furthermore, after the synchronous belt is installed, the first and second sections are fixed together with screws, which facilitates the tensioning of the synchronous belt.

[0044] Linkage C 525 is a split structure, comprising a first section and a second section. The first section connects to the drive shaft 516, and the second section connects to the tool shaft 529.

Furthermore, after the synchronous belt is installed, the first and second sections are fixed together with screws, which facilitates the tensioning of the synchronous belt.

[0045] Link D 526 is a split structure, comprising a first section and a second section. The first section connects to the drive shaft 517, and the second section connects to the tool shaft 530. The first and second sections are detachably and fixedly connected. Since power is transmitted between the drive shaft 517 and the tool shaft 530 via a synchronous belt, the split structure of link D 526 facilitates the installation of the synchronous belt.

[0047] The drive shafts of grooving device A5 and grooving device B6 are arranged at intervals and evenly. That is, the adjacent drive shafts of grooving device A5 are spaced 90° apart, the adjacent drive shafts of grooving device B6 are spaced 90° apart, and the drive shaft of grooving device A5 and the adjacent drive shaft of grooving device B6 are spaced 45° apart.

[0048] The process of grooving the troughs of a plastic corrugated pipe using the grooving system of this utility model is described in detail below:

[0049] Select the appropriate spiral guide sleeve based on the type of plastic corrugated pipe to be processed.

[0050] The clamping cylinder drives the active connecting rod 518 to move, which in turn drives the driven connecting rods 519, 520, 521, and 522 to move. Connecting rods A, B, C, and D move, and the tool shafts 527, 528, 529, and 530 move toward the plastic corrugated pipe and finally clamp the plastic corrugated pipe.

[0051] The spiral guide sleeve drives the plastic corrugated pipe to move forward. The structure of the spiral guide sleeve and the process of the spiral guide sleeve driving the plastic corrugated pipe to move forward are well known to those skilled in the art, and will not be described in detail again.

[0052] The grooving power component drives each cutter to rotate and groove the troughs of the plastic corrugated pipe. The grooving ends when the plastic corrugated pipe is removed from the plastic corrugated pipe grooving system of this utility model.

[0053] The reverse movement of the clamping cylinder's telescopic rod drives the active connecting rod 518 to move in the opposite direction, which in turn drives the driven connecting rods 519, 520, 521, and 522 to move. Connecting rods A, B, C, and D move, and the tool shafts 527, 528, 529, and 530 move away from the plastic corrugated pipe.
