[0007] Specifically, the positioning structure includes a buckle, a strap, a first Velcro hook surface and a first Velcro loop surface. The buckle is connected at equal distances along the outer skin of the heating cable, and the strap passes through the buckle.

[0008] By adopting the above technical solution, the heating cable is bundled and positioned with the oil well pipeline through the positioning structure, so that the heating cable can heat the oil well pipeline to reduce the viscosity of the mined material inside the pipeline, improve fluidity, and facilitate mining.

[0009] Specifically, the first Velcro hook surface and the first Velcro loop surface are sewn along two sides of the strap respectively.

[0010] Specifically, the inner wall of the thermal insulation sleeve is equidistantly connected with a third Velcro loop surface corresponding to the first Velcro hook surface.
