     The lighter  90  includes an outer threaded portion  91  on an outer surface thereof. The lighter  90  is screwed into the inner threaded portion  82  of the medium connecting element  80  through the outer threaded portion  91 . 
     The aforementioned is the summary of the positional and structural relationship of the respective components of the preferred embodiment in accordance with the present invention. 
     After the assembly of the above respective components is finished, the respective extension tubes  20  in the receiving body  50  can be used to hold and store the cigar A, and the lighter  90  and the bottom storage unit  70  seal the second ends of the respective extension tubes  20 . The lighter  90  can be taken out when necessary, and when the lighter  90  is taken out, an end of the receiving body  50  is opened to allow the user to take out or put in the cigar A. When the length of the cigar A is greater than a length of the receiving body  50  in the axial direction X, the user can pull the medium connecting element  80  or the bottom storage unit  70  which is screwed to the respective extension tubes  20 , so that the two extension tubes  20  can move away from each other to extend the length of the cigar holder in accordance with the present invention for holding longer cigar A, as shown in  FIG. 10 . As known from this, the bi-directional multiple-layer pull-in cigar holder in accordance with the present invention can be adjusted in length by the user, improving its applicability. Since the bi-directional multiple-layer pull-in cigar holder in accordance with the present invention is assembled with the lighter  90 , the user doesn&#39;t need to additionally carry a lighter, improving the use convenience. 
     To assemble the respective extension tubes  20 , the respective elastic retaining rings  40  will be compressed first, so that the extension tubes  20  can be disposed in the receiving body  50 . When the respective extension tubes  20  are received in the receiving body  50 , the elastic retaining rings  40  will elastically abut against the inner surface of the receiving body  50  due to the fact that the respective elastic retaining rings  40  are fastened on the circular bases  30 , as a result of this, the respective elastic retaining rings  40  can offer a displacement resistance with respect to the receiving body  50 , synchronously avoiding the disengagement of the respective extension tubes  20 . 
     Since the elastic retaining rings  40  are C-shaped big-area plates, they can improve the convenience in assembly while offering a more stable resistance, thus ensuring a high operation stability of the cigar holder in accordance with the present invention. 
     Further, as shown in  FIG. 11 , the lighter  90  can be disassembled for use. After the lighter  90  is disassembled, the bottom storage element  72  of the storage unit  70  can be disassembled from the bottom cover  71  and screwed to the second inner threaded portion  82  of the medium connecting element  80  through the outer threaded portion  722 , so that the bottom cover  71  and the bottom storage element  72  of the bottom storage unit  70  can seal both ends of the cigar holder in accordance with the present invention. 
     Furthermore, as shown in  FIGS. 12-15 , in another embodiment, the cigar holder in accordance with the present invention can be further provided with an adjusting extension tubes  20 ′ outside each of the extension tubes  20 . The adjusting extension tubes  20 ′ are in structure similar to the extension tubes  20 . Each of the adjusting extension tubes  20 ′ includes a first outer threaded portion  21 ′ and a second outer threaded portion  22 ′ on both ends thereof. The first outer threaded portion  21 ′ of each of the adjusting extension tube  20 ′ is screwed to one circular base  30 , and each of the circular bases  30  is also screwed with one elastic retaining ring  40 . The second outer threaded portion  22 ′ of each of the respective adjusting extension tubes  20 ′ is also screwed with one end cap ring  60 . The extension tubes  20  which are engaged to the respective adjusting extension tubes  20 ′ are located at the same end of the respective adjusting extension tubes  20 ′ as the respective circular bases  30 , and the receiving body  50  is mounted outside the respective extension tubes  20  and the respective adjusting extension tubes  20 ′ with the respective circular bases  30  being located adjacent to each other. By such arrangements, it can form a three-layer extension structure, increasing the extension length of the present invention while further improving the applicability of the present invention. 
     Moreover, as shown in  FIG. 16 , the respective components of the present invention can be increased in diameter such that the cigar holder in accordance with the present invention can hold much more cigars A, further increasing the applicability of the present invention. 
     While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
