• the inner core includes a first weaving thread and a plurality of second weaving threads;
• the first weaving thread interweaves and intertwines with the second weaving threads along a lengthwise direction, with the second weaving threads being secured to the first weaving thread, thereby defining a plurality of enlarged portions and a plurality of separation portions;
• each of the enlarged portions of the inner core has an outer diameter greater than that of the first weaving thread;
• the liner is formed by a plurality of fibers which are weaved together;
• the liner defines a cavity for receiving the inner core which is hidden in and covered by the cavity of the liner;
• the liner is squeezed by the enlarged portions of the inner core and defines a plurality of expanded sections and a plurality of recessed sections;
• the expanded sections of the liner respectively corresponds to the enlarged portions of the inner core;
• the recessed sections of the liner respectively corresponds to the separation portions of the inner core;
• and
• the outer sleeve defines a chamber for receiving the liner which contains the inner core.
