The other end of the push block 4 is connected to a first spring 6, and the other end of the first spring 6 is connected to the inner wall of one end of the cavity. Two symmetrical movable blocks 7 are also provided on one side of the push block 4. One end of the movable block 7 slides in the through grooves 8 starting from both ends of the second drum body 2. A second spring 9 is also connected to one side of the movable block 7. One end of the movable block 7 is connected to the inner wall of one end of the through groove 8. The other side of the movable block 7 is also connected to a clamping block 10. One end of the clamping block 10 extends out of the through groove 8 and enters the slot 11 set at the edge of the through groove 8 on both ends of the second roll body 2. One end of the clamping block 10 is also adapted to the locking hole opened on the insert block 12 inserted inside the slot 11. One end of the insert block 12 is connected to both ends of the first roll body 1. Both ends of the second roll body 2 are also provided with multiple sets of symmetrical positioning posts 13. One end of two positioning posts 13 is adapted to the positioning hole opened at one end of the thermal paper body 3. One end of the second roll body 2 is also adapted to the corresponding positioning holes on both ends of the first roll body 1. More specifically, by pressing the push rod 5 that extends from one end of the second roll body 2, it causes the push block 4 connected to one end to slide along the cavity and squeeze the first spring 6. At the same time, the two movable blocks 7 on one side of the push block 4 slide along the through grooves 8 on both ends of the second roll body 2 and pressurize the second spring 9, so that the clamping block 10 connected to one side retracts into the through groove 8. Then, the positioning hole on one end of the thermal paper body 3 is matched with the two sets of positioning posts on both ends of the second roll body 2. Two of the components in section 13 are fitted together.
