Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 4, a spiral adhesive tape includes a support ring 1 and a surface layer 2 wound around the support ring 1. The inner side of the surface layer 2 is coated with a first glue layer 21, and the outer side of the surface layer 2 is coated with a second glue layer 22; the width of the first adhesive layer 21 and the second adhesive layer 22 is 1/3 of the width of the surface layer 2. The first glue layers 21 abut against the second glue layers 22 when the surface layer 2 is spirally wound.

The supporting ring 1 is rotatably connected with a supporting sleeve 3 which is coaxially arranged, the supporting sleeve 3 is fixedly connected with a protective disc 4, and the second glue layer 22 is positioned in the protective disc 4. A discharge port 41 for extending the surface layer 2 is formed in the protective disc 4, and a shearing mechanism 5 for cutting off the surface layer 2 is arranged at the discharge port 41.

Wherein, the shearing mechanism 5 comprises a driving rod 51, a connecting rod 52, a supporting frame 53, a conducting component 6 and a cutting knife 7. The supporting frame 53 is fixed on the protective disc 4, the driving rod 51 is connected on the supporting frame 53 in a sliding way, and the sliding direction of the driving rod 51 is parallel to the axis of the supporting ring 1. The two ends of the connecting rod 52 are respectively hinged with the driving rod 51 and the conducting component 6. The cutter 7 is fixed to the conductive member 6.

The conductive assembly 6 includes a connecting plate 61, arcuate teeth 62 and a rack gear 63. The connecting plate 61 is fixed on the arc-shaped teeth 62 and hinged with the connecting rod 52, and the rack 63 is connected on the supporting frame 53 in a sliding mode and fixedly connected with the blade. The arc-shaped teeth 62 are meshed with the rack 63, and the arc-shaped teeth 62 are rotatably connected to the support frame 53.

In order to facilitate the pulling of the driving rod 51, a pulling ring 8 is fixed to an end of the driving rod 51 remote from the cutting knife 7.

A return spring 9 is provided between the drive lever 51 and the support bracket 53.

In conclusion, during the use, take out top layer 2 from discharge gate 41, when getting suitable length, pulling pull ring 8, reset spring 9 deformation, actuating lever 51 moves towards the direction of keeping away from cutter 7, and actuating lever 51 drives connecting rod 52 and removes, and connecting rod 52 drives connecting plate 61 and removes, makes connecting plate 61 drive arc tooth 62 rotatory then, makes arc tooth 62 drive rack 63 and removes, makes two cutters 7 be close to each other and realize cutting off top layer 2 then. After the pull ring 8 is loosened, the driving rod 51 and the cutting knife 7 can be reset through the elastic force action of the reset spring 9. When winding up on the pencil with top layer 2 with the mode of spiral, first glue film 21 contradicts and pastes fixedly with second glue film 22, greatly promotes the firmness between top layer 2 and the top layer 2 to can effectively avoid the phenomenon of coming unstuck, promote to use and experience.
