The fixing seat  51  of the support rack  50  is mounted on the first end of the support member  90 , and the locking screw  53  is extended through the fixing hole  512  of the support rack  50  and screwed into the screw bore  93  of the support member  90 , so that the support rack  50  is fixed on the support member  90 . The support member  90  has a second end formed with a screw bore  92  (see  FIG. 9A ), the mounting hole  31  of the blade seat  30  is mounted on the second end of the support member  90 , and the locking screw  34  is extended through the fixing hole  32  of the blade seat  30  and screwed into the screw bore  92  of the support member  90 , so that the blade seat  30  is fixed on the support member  90 . The support member  90  has a mediate portion formed with a ramp  94  spaced from the rotation wheel  60 . 
   As shown in  FIG. 10 , a roll of adhesive tape  70  is wound around the rotation wheel  60  and has a distal end directly rested on the serrated blade  33  of the blade seat  30 . 
   Accordingly, the adhesive tape holder is attached on a plane rigidly and stably, thereby facilitating the user operating the adhesive tape holder so as to pull the adhesive tape  70  outward easily and conveniently. In addition, the adhesive tape holder is available for a horizontal plane and a vertical plane, thereby facilitating the user operating the adhesive tape holder. Further, the adhesive tape holder has a light weight and can be folded easily, thereby facilitating transportation and saving space of storage of the adhesive tape holder.
