Embodiment Construction

[0007] When the present invention is used as a pen holder or a pipe sheath, the innermost layer can be fixed on the pen core or pipe with an adhesive tape, and when the long sleeve used as a short pencil can not be fixed together with the rod body to be clamped, especially When the cross-section is a perfect circle and the surface is very smooth, it is better to make one or both ends of the innermost layer of the sleeve into a shape longer than the other layers, and press the inner layer longer than the other layers on the clamped rod by hand. On the shape body, it will be more convenient and faster to roll the pipe cover and the rod shape more tightly.

[0008] A new type of sleeve can be re-rolled from the outermost layer as the innermost layer. When a part of the sleeve is rolled up, two parallel sleeves are formed. Socket. A new type of pipe sleeve can also be made by overlapping several sections of coiled material, one end of each section is connected to each other, and ...
