Abstract: The present application relates to a steel-pipe-embedded structure for a packaging and transportation box of a reel, and relates to a field of a pallet of the packaging and transportation box of the reel, which includes a pallet body embedded with a steel pipe and integrally formed with a steel pipe channel for receiving the steel pipe, in which both ends of the steel pipe channel are closed. In the present application, because the steel pipe can support the pallet body, a strength and a bearing capacity of the pallet body can be effectively improved. Further, a possibility of deformation caused by long term use is reduced, and an exposure of the steel pipe can be effectively avoided, so that a corrosion of the steel pipe is effectively reduced.

Abstract: Disclosed are a support mechanism and a transport container, the technical field of support and accommodation mechanism is involved, comprising at least one group of supporter, each group of the supporters comprises two opposite support plates, and two of the support plates belonging to a same group are configured to jointly form a placement opening for insertion of a mandrel, wherein a top wall of one of the support plates is provided with a positioning block, and a bottom wall of another corresponding one of the support plates is provided with a positioning slot for insertion of the positioning block.

Abstract: A spool includes a tube for winding a material. The outer surface of the tube is provided with a step portion along the axial direction thereof. The step portion is as high as the thickness of the material. A cutting groove is provided on a side, close to the axial centre of the tube, of the step portion. A resilient clip for clamping the material is fixed in the cutting groove, the upper end of the resilient clip is connected to a notch on one side of the cutting groove, and the lower end thereof is inclined towards the other side of the cutting groove. The spool positions a cutter by means of the cutting groove, and the resilient clip clamps the cut material in the cutting groove.
