The two circular bases  20  cooperates with the respective elastic retaining rings  40  and the O-shaped rings  13  of the receiving body  10  to prevent the disengagement of the two extension tubes  30 . 
         [0037]    The two decorating sleeves  50  are hollow thin tubes. Each of the two decorating sleeves  50  is provided with a decoration portion  51  on an outer surface thereof. An X directional length of each of the two decorating sleeves  50  equals an X directional distance from the abutment end element  32  of the respective extension tubes  30  to the outer threaded portion  31  of the corresponding extension tube  30 . The decorating sleeves  50  are mounted on the respective extension tubes  30 . 
         [0038]    The bottom storage unit  60  includes a bottom cover  61  and a bottom storage element  62 . The bottom cover  61  is formed with a first inner threaded portion  611  and a second inner threaded portion  612  in both ends thereof. One of the inner threaded portions  611 ,  612  is screwed to the other one of the outer threaded portions  31  of one of the extension tubes  30 . In the present embodiment, the first inner threaded portion  611  of the bottom cover  61  is screwed on the outer threaded portion  31  of the one of the extension tubes  30 . The bottom storage unit  60  has an open end and includes a storage space  621  in the open end thereof. The bottom storage unit  60  includes an outer threaded portion  622  on the open end thereof. The bottom storage element  62  is screwed to the second inner threaded portion  612  of the bottom cover  61  through the outer threaded portion  622  of the bottom storage unit  60 . 
         [0039]    The medium connecting element  70  is in the form of a ring and includes a first inner threaded portion  71  and a second inner threaded portion  72  in both ends thereof. The medium connecting element  70  is screwed on the other one of the outer threaded portions  31  of the other one of the two extension tube  30  through the first inner threaded portion  71 , and the second inner threaded portion  72  is allowed to be screwed on the outer threaded portion  622  of the bottom storage element  62 . 
         [0040]    The lighter  80  includes an outer threaded portion  81  on an outer surface thereof. The lighter  80  is screwed into the second inner threaded portion  72  of the medium connecting element  70  through the outer threaded portion  81 . 
         [0041]    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. 
         [0042]    After the assembly of the above respective components of the present invention is finished, cigars A may be held and stored in the receiving body  10 , and the lighter  80  and the bottom storage unit  60  will seal both ends of the receiving body  10 . When in use, the lighter  80  can be taken down when necessary, and when the lighter  80  is taken down, an end of the receiving body  10  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 in the axial direction X of the receiving body  10 , the user can pull the two extension tubes  30  by himself to make the two extension tubes move away from each other, so that the length of the receiving body  10  will be increased enough for holding the cigar A, as shown in  FIG. 8 . As known from this, the bi-directional multiple-layer extension 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 extension 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. 
         [0043]    Furthermore, in addition to facilitating positioning by cooperating with the through hole  221  of the respective circular bases  20 , the respective elastic retaining rings  40  which are C-shaped elastic plates can further increase the convenience in assembly since it has a big-area configuration. Likewise, due to the big-area configuration, the elastic retaining rings  40  can offer a more stable function of preventing disengagement, ensuring the respective extension tubes  30  to have the best structure stability. 
         [0044]    Further, as shown in  FIG. 9 , the lighter  80  can be taken down for use. After the lighter  90  is taken down, the bottom storage element  62  of the storage unit  60  can be disassembled from the bottom cover  61  and screwed to the second inner threaded portion  72  of the medium connecting element  70  through the outer threaded portion  622 , so that the bottom cover  61  and the bottom storage element  62  of the bottom storage unit  60  can seal both ends of the cigar holder in accordance with the present invention to define a space therein for use. Further referring to  FIG. 10 , 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. 
         [0045]    Additionally, as shown in  FIGS. 11-14 , in another embodiment of the present invention, the cigar holder in accordance with the present invention can be further provided with two second extension tubes  30 ′ on the receiving body  10 , and then the two extension tubes  30  are mounted on the respective second extension tubes  30 ′. The second extension tubes  30 ′ are in structure similar to the extension tubes  30 . Each of the second extension tubes  30 ′ includes an outer threaded portion  31 ′ on each of two opposite ends thereof. The outer threaded portion  31 ′ on a first end of each of the second extension tube  30 ′ is screwed to a second abutment end element  32 ′ having an inner threaded portion  321 ′ on an inner surface thereof, and the outer threaded portions  31 ′ on a second end of each of the second extension tubes  30 ′ is screwed to the inner threaded portion  21  of the respective circular bases  20 . The elastic retaining rings  40  are also engaged on the respective circular bases  20 . In addition, the respective second extension tubes  30 ′ are formed in an outer surface thereof with a circular groove  33 ′ which is located adjacent to the outer threaded portion  31  on the second end of the corresponding second extension tube  30 ′. An O-shaped ring  13  is disposed in the circular groove  33 ′. The respective second extension tubes  30 ′ are mounted on the receiving body  10  in such a manner that the second abutment end elements  32 ′ are abutted against each other, and the respective extension tubes  30  are then mounted on the respective second extension tubes, such that a three-layer extension structure in accordance with the present invention is obtained, widening the length adjustment range while further enhancing the operation applicability. 
         [0046]    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.
