[0057] Further, the plurality of protrusions 240 have different widths. The wider protrusions 240 have a larger contact area with the fixing hole 330, a smaller unit area pressure, and can form a more uniform frictional resistance. The narrower protrusions 240 have a smaller contact area, a larger unit pressure, and are prone to form a local high frictional resistance. Thus, the frictional resistance distribution is optimized through non-uniform pressure distribution.

[0058] With reference to Figure 1 According to some embodiments of the present application, the direction of the light source 130 is perpendicular to the axial direction of the connecting pipe 200.

[0059] It can be understood that the direction of the light source 130 is perpendicular to the axial direction of the connecting pipe 200, so as to facilitate increasing the illumination range of the light source 130.
