When the machine is running from the straight surface to the pressure frame 2002, the arc surface of the first support piece 1803 and the second support piece 1804 rotates to the highest point, and the second spring 2007 squeezes the pressure frame 2002 to form a rapid sliding on the surface of the first support piece 1803 and the second support piece 1804 in accordance with the direction of the conversion motor 1801, so that the straight surface of the first support piece 1803 and the straight surface of the second support piece 1804 are instantly fitted with the bottom surface of the pressure frame 2002, so that the saw frame 2008 and the sawtooth piece 2009 are driven to instantly impact downward and extend, so that the sawtooth piece 2009 passes through the gear bar 2003 to cut the tape and is rebounded by the third spring 2012, so that the tape on the surface of the inner winding roller 25 is in a cut state.At the same time, the driven gear 24 on the inner winding roller 25 is now meshed with the output shaft 22, causing the inner winding roller 25 to rotate and rewind the tape. The twist wheel 1903 is then twisted to retract the threaded column 1902, removing the outer winding roller 25. The tape reel and the discarded tape on the surface are removed, and a new tape reel is replaced. The inner winding roller 25 is then installed in its original position. The inner winding roller 25 is then twisted to push the second transmission shaft 1904, securing the winding roller 25.
