Adhesive tape cutting device with a pivotable retaining plate for retaining a tape roll

An adhesive tape cutting device comprising:

• a body including
• a large side wall having a front portion and a rear portion, which is formed with a roll mounting shaft that extends perpendicular thereto and that is adapted to mount an adhesive tape roll therearound, a small side wall parallel to said large side wall, and
• a connecting wall having a front end, a rear end, and two opposite sides that are formed respectively and integrally with and that are perpendicular to said large and small side walls;
• a cutting blade disposed fixedly on said front end of said connecting wall;
• a roller disposed rotatably among said front end of said connecting wall, said large side wall and said small side wall , and disposed adjacent to said cutting blade and parallel to said roll mounting shaft;
• a retaining plate mounted pivotally on said large side wall and having a blocking plate portion that is locked releaseably on said small side wall so as to be adapted to confine the tape roll between said blocking plate portion of said retaining plate and said large side wall, said blocking plate portion of said retaining plate having an outer surface and being rotatable away from said roller and said roll mounting shaft to an open position when unlocked from said small side wall, thereby permitting removal of the tape roll from said roll mounting shaft;
• and
• a tape-pressing member disposed pivotally on said retaining plate and adapted to be biased to press a free end portion of a tape on the tape roll against said roller, thereby retaining the free end portion of the tape between said tape-pressing member and said roller, said tape-pressing member being removed from said roller when said blocking plate portion of said retaining plate is moved to said open position;
• whereby, the free end portion of the tape can be pulled forwardly so as to move between said roller and said tape-pressing member.
