[0024] Referring to Figure 1-6 , an embodiment of a self-cutting tape roll of the present utility model includes a limiting cylinder 1. A connecting cylinder 2 is rotatably connected to the limiting cylinder 1. A tape 3 is arranged on the outer surface of the connecting cylinder 2.

A blade 6 is fixedly connected to the upper surface of the docking block 5. A concave block 7 is fixedly connected to the front surface of the bearing block 4. A limiting rod 8 is fixedly connected to the side surface of the concave block 7. A movable plate 9 is rotatably connected to the outer surface of the limiting rod 8. The side surface of the movable plate 9 is in contact with the concave block 7. A protective shell 10 is fixedly connected to the rear surface of the movable plate 9. A first magnet 11 is fixedly connected to the rear surface of the protective shell 10. A second magnet 12 is fixedly connected to the rear surface of the bearing block 4. The lower surface of the first magnet 11 is magnetically connected to the second magnet 12. A docking groove 13 is formed in the bearing block 4. The outer surface of the docking block 5 is movably connected to the docking groove 13. The upper surface of the bearing block 4 is in contact with the protective shell 10.

[0025] A sliding rod 14 is slidably connected to the inner surface of the bearing block 4. Anti - detachment blocks 15 and connecting plates 16 are respectively fixedly connected to both ends of the sliding rod 14. A connecting block 17 is fixedly connected to the upper surface of the connecting plate 16. The number of the connecting blocks 17 is two and they are distributed front and back. A fixing block 18 is fixedly connected to the left surface of the connecting block 17. The number of the fixing blocks 18 is two and they are distributed front and back. Fixing grooves 20 are formed in the docking block 5. The number of the fixing grooves 20 is two and they are distributed front and back. The outer surface of the fixing block 18 is movably connected to the fixing groove 20. A spring 19 is slidably sleeved on the outer surface of the sliding rod 14. One end of the spring 19 is fixedly connected to the side surface of the anti - detachment block 15. The end of the spring 19 far from the anti - detachment block 15 is fixedly connected to the side inner wall of the bearing block 4. A limiting groove 21 is formed in the bearing block 4. The outer surface of the anti - detachment block 15 is slidably connected to the limiting groove 21. The outer surface of the fixing block 18 is slidably connected to the bearing block 4.

[0026] Working principle: When it is necessary to cut the tape 3 after using the tape 3 to complete the bonding of an item, by pulling the protective shell 10, the movable plate 9, the protective shell 10 and the first magnet 11 can be flipped with the limiting rod 8 on the concave block 7 as the central axis. When the flipped protective shell 10 no longer contacts the bearing block 4, the blade 6 can be exposed. Then, the tape 3 is brought into contact with the blade 6. Under the action of the blade 6, the cutting of the tape 3 can be realized. After the tape 3 is cut, by flipping the protective shell 10 in the reverse direction, the flipped protective shell 10 drives the movable plate 9 and the first magnet 11 to flip. When the flipped first magnet 11 contacts the second magnet 12, under the magnetism of the first magnet 11 and the second magnet 12, the fixation between the bearing block 4 and the protective shell 10 can be realized, so that the protective shell 10 can protect the blade 6 and prevent personnel from accidentally touching the blade 6. When the blade 6 is accidentally damaged during use and needs to be replaced, by pulling the connecting plate 16, the moving connecting plate 16 can drive the sliding rod 14 to move, so that the moving sliding rod 14 can drive the anti - detachment block 15 to move in the limiting groove 21. Furthermore, the moving anti - detachment block 15 can squeeze the spring 19 on the inner wall of the bearing block 4, making the spring 19 in a tense state. At the same time, the moving connecting plate 16 will also drive the connecting block 17 and the fixing block 18 to move. When the moving fixing block 18 disengages from the fixing groove 20, the fixation of the docking block 5 and the blade 6 is released. Then, by pulling the blade 6, the docking block 5 and the blade 6 can be removed from the bearing block 4. Then, the docking block 5 on the new blade 6 is inserted into the docking groove 13. When the docking block 5 is completely inserted into the docking groove 13, the fixing block 18 and the fixing groove 20 can correspond to each other. Then, release the pulled connecting plate 16, so that the spring 19 is no longer restricted by the pulling force and rebounds. Furthermore, the rebounding spring 19 can drive the sliding rod 14, the anti - detachment block 15, the connecting plate 16, the connecting block 17 and the fixing block 18 to move back to their original positions. When the moving fixing block 18 enters the fixing groove 20, the fixation of the docking block 5 and the blade 6 is completed, thus realizing the connection between the bearing block 4 and the blade 6 and completing the replacement of the blade 6.
