[0023] The outer surface of outer wear-resistant layer 131 is provided with groove 133, and wear-resistant assembly 2 is staggered distributed on the surface of outer wear-resistant layer 131 and movable groove 132, so that the distance between the adjacent two rolling rollers 22 and the center of wear-resistant shell 13 is greater than the diameter of wear-resistant shell 13, so that the outer surface of wear-resistant assembly 2 is contacted by ground in the process of dragging PE pipe, at the same time, the diameter of rolling roller 22 is effectively reduced by the groove 133, and then the weight and volume of PE pipe are reduced.

[0026] Among them, snap hole 135 is located at the center position of movable groove 132.

[0027] As shown in the accompanying Figure 5As shown, there are multiple wear-resistant components 2, and the wear-resistant components 2 include a supporting steel wire 21, and multiple rolling rollers 22 are rotatably installed on the outer surface of the supporting steel wire 21.

[0028] Among them, the supporting steel wire 21 is fixedly installed inside the clamping hole 135 of the clamping ring 134, and the rolling roller 22 is rotatably installed inside the movable groove 132.
