[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, with elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive evenly coated on the above base material. It consists of three parts: base material, adhesive, and release paper (film) or silicone oil paper.

[0003] At present, in order to facilitate users to cut double-sided tape, most of them are provided with a serrated knife on the double-sided tape, and an easy-to-tear hole can be formed on the double-sided tape by pressing the serrated knife. At this time, the easy-to-tear hole makes it more convenient for users to cut the double-sided tape. For example, a double-sided tape with detachable foam is disclosed in Chinese patent publication No. CN218909338U. However, since the serrated knife on the double-sided tape cannot be replaced, the serrated knife often becomes blunt and cannot cut the double-sided tape smoothly, which makes it more troublesome for users to cut the double-sided tape.

[0024] Reference Figure 1-4A double-sided tape that is easy to intercept, includes a supporting tube 1, a tape body 2 is bonded to the surface of the supporting tube 1, a first bearing 3 is fixedly connected to the inner wall of the supporting tube 1, a first cylinder 4 is fixedly connected to the inner wall of the first bearing 3, a vertical plate 5 is fixedly connected to the upper surface of the first cylinder 4, a strip hole 6 is opened inside the vertical plate 5, a rotating bracket 7 is fitted on the inner wall of the strip hole 6 and the surface of the vertical plate 5, a magnetic column 8 is fitted on the inner wall of the rotating bracket 7, a toothed knife 9 is fixedly connected to the bottom of the magnetic column 8, a hand-tightening bolt 10 is threadedly connected to the inner wall of the rotating bracket 7, and a rubber ring 11 is fitted on the surface of the hand-tightening bolt 10 and the side of the rotating bracket 7.

[0025] The rotating bracket 7 includes a sliding sleeve 71, the inner wall of the sliding sleeve 71 contacts the surface of the vertical plate 5, and the sliding sleeve 71 is guided by the vertical plate 5. A circular hole 72 is opened on both sides of the sliding sleeve 71. A second bearing 73 is fixedly connected to the inner wall of the circular hole 72. A second cylinder 74 is fixedly connected to the inner wall of the second bearing 73. The surface of the second cylinder 74 contacts the inner wall of the strip hole 6. The length of the strip hole 6 is greater than the diameter of the second cylinder 74. The second cylinder 74 can slide up and down in the strip hole 6. A groove 75 is opened at the bottom of the second cylinder 74. The sliding sleeve 71 The side of the second cylinder 74 is fixedly connected with an arc column 76, the upper surface of the arc column 76 and the inner wall of the groove 75 are in contact with the surface of the magnetic column 8, the left and right sides of the second cylinder 74 are provided with a threaded groove 77, the inner wall of the threaded groove 77 is threadedly connected with the surface of the hand-tightening bolt 10, and the side of the sliding sleeve 71 is in contact with the side of the rubber ring 11. When the hand-tightening bolt 10 is tightened, the hand-tightening bolt 10 and the sliding sleeve 71 can clamp or loosen the rubber ring 11 through the cooperation of the hand-tightening bolt 10 and the threaded groove 77. When the hand-tightening bolt 10 and the sliding sleeve 71 clamp the rubber ring 11, The friction between the rubber ring 11 and the hand-tightening bolt 10 and the sliding sleeve 71 can prevent the second cylinder 74 from rotating. When the hand-tightening bolt 10 and the sliding sleeve 71 loosen the rubber ring 11, the second cylinder 74 can rotate freely. The suction force of the magnetic column 8 on the second cylinder 74 is greater than the sum of the gravity of the magnetic column 8 and the toothed cutter 9. The bottom of the arc column 76 and the side of the sliding sleeve 71 are fixedly connected with the magnetic block 19. When the magnetic column 8 is inserted into the groove 75, the magnetic column 8 is fixed in the groove 75 through the suction force of the magnetic column 8 on the second cylinder 74, so that the user can rotate the second cylinder. 74, the magnetic column 8 will not fall off from the groove 75. At the same time, when the magnetic column 8 is aligned with the magnetic block 19, the mutual attraction between the magnetic column 8 and the magnetic block 19 can make the second cylinder 74 difficult to rotate. Then, through the cooperation of the magnetic column 8 and the magnetic block 19, it is convenient for the user to rotate the magnetic column 8 to the bottom of the second cylinder 74. When the magnetic column 8 contacts the arc column 76, the toothed knife 9 can be fixed on the rotating bracket 7 through the cooperation of the groove 75, the magnetic column 8 and the arc column 76. When the magnetic column 8 is separated from the arc column 76, the toothed knife 9 can be directly separated from the rotating bracket 7.

[0026] Embodiment 2:

[0027] Reference Figure 1-5 A threaded hole 12 is provided inside the first cylinder 4, and a sealing cover 13 is threadedly connected to the inner wall of the threaded hole 12. A first baffle 14 is fixedly connected to the left side of the first cylinder 4. Through the cooperation of the threaded hole 12, the sealing cover 13 and the first baffle 14, a spare toothed cutter 9 can be stored in the first cylinder 4, so that the user can quickly find the spare toothed cutter 9 when replacing the toothed cutter 9.

[0028] A sliding hole 15 is provided inside the first baffle plate 14, and an indicator column 16 is fitted on the inner wall of the sliding hole 15. A second baffle plate 17 is fixed to the right side of the indicator column 16, and a spring 18 is fixedly connected to the left side of the second baffle plate 17 and the right side of the first baffle plate 14. When the rear toothed cutter 9 is stored in the threaded hole 12, the toothed cutter 9 is used to move the left end of the indicator column 16 out of the sliding hole 15. When there is no toothed cutter 9 in the threaded hole 12, the spring 18 is used to move the left end of the indicator column 16 into the sliding hole 15, so that the user can intuitively judge whether there is a spare toothed cutter 9 in the threaded hole 12 by observing the position of the indicator column 16.

[0029] In the utility model, when the user uses the double-sided tape, he first pinches the end of the tape body 2 and uncovers the outer tape body 2. When the uncovered tape body 2 reaches a suitable length, the second cylinder 74 on the rotating bracket 7 is pressed to make the toothed knife 9 press the tape body 2, and the toothed knife 9 forms an easy-to-tear opening on the tape body 2. At this time, the tape body 2 can be torn off through the easy-to-tear opening. When it is necessary to replace the toothed knife 9, the hand-tightening bolt 10 is first turned to loosen the rubber ring 11 of the hand-tightening bolt 10 and the slide cylinder, and then the second cylinder 74 is turned to make the toothed knife 9 The magnetic column 8 is staggered with the arc column 76, and the magnetic column 8 is taken out from the groove 75. Then, the magnetic column 8 on the new toothed cutter 9 is inserted into the groove 75, and the second cylinder 74 is rotated to make the magnetic column 8 contact with the arc column 76. Then, by rotating the hand bolt 10, the hand bolt 10 and the sliding sleeve 71 clamp the rubber ring 11, and the friction between the rubber ring 11, the hand bolt 10 and the sliding sleeve 71 prevents the second cylinder 74 from rotating. At this time, the toothed cutter 9 can be fixed on the rotating bracket 7 through the cooperation of the groove 75, the magnetic column 8 and the arc column 76.
