During installation, the second end of the guide sleeve 202 is aligned with the shaft 101 and pushed axially to allow the shaft 101 to enter the guide sleeve 202. At the same time, the guide member 205 slides along the guide groove 102. S2. When the shaft body 101 reaches a position close to the inner hole of the pressure cover 204, the pressure cover 204 is pushed to move in a direction toward compressing the elastic element 207, so that the locking member 206 passes through the guide groove 102 and reaches the entrance position of the transition section 103a; S3. Rotate the pressing cover 204 (for example, 20°-30°) (clockwise) so that the locking member 206 enters the transition section 103a and reaches its tail end; release the pressing cover 204, and the elastic element 207 allows the locking member 206 to enter the locking section 103b and complete the locking. At this time, the paper tape reel is installed between the paper tape tray 105 and the paper pressure reel 201.
