Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coil, more particularly, it relates to a double coil for binding. BACKGROUND

[0002] Binding refers to processing printed pages or booklets into books, or arranging and matching single documents, bills, etc. to bind into books and other post-printing processing. Common binding methods include glue binding, ring binding, thread binding, etc. Double coils are often involved in ring binding.

[0003] Double coils can be divided into two types according to material: spray coating and nylon coating. Spray coating is formed by spraying powder on a wire, and then attaching the powder to the wire through high temperature. Nylon coating is formed by wrapping a steel wire with a layer of nylon through a special process. Regardless of the material, the double coil generally needs to first punch holes in the pages to be bound, then place the pages in the double coil in order, and then close the double coil. To remove the pages, the double coil is opened, and then the pages are removed. The double coil deforms during opening and closing, and after repeated deformation, the double coil cannot recover to its original shape due to metal fatigue of the metal material, which affects normal use.

[0004] Therefore, a new solution is needed to solve this problem. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a double coil for binding to solve the technical problems raised in the background art.

[0007] The present application further provides that the connecting piece comprises a groove provided in the side wall of the first connecting block and extending in the length direction of the first connecting block, a sliding block slidingly connected in the groove, a plurality of clamping blocks fixedly connected to the surface of the sliding block facing the second connecting block, and a plurality of clamping grooves provided in the surface of the second connecting block facing the first connecting block, a plurality of moving grooves are provided in the first connecting block for the movement of the clamping blocks, and a limiting part is provided on the second connecting block for fixing the clamping blocks in the clamping grooves.

[0008] The sliding block is fixedly connected with an extension block at one end away from the groove.

[0009] The limiting part comprises a limiting slot arranged on the side wall of the second connecting block and along the length direction of the second connecting block, a limiting block inserted into the limiting slot, and a cover body hinged on one end of the second connecting block to close the limiting slot.

[0010] The second connecting block is provided with a connecting ring at one end away from the cover body.

[0011] The connecting ring comprises a ring body and an identification block fixedly connected with the ring body, and the second connecting block is provided with a placing slot at one end away from the cover body, one end of the identification block is rotationally connected in the placing slot, and the other end is attracted to the placing slot through a magnetic sheet.

[0012] In summary, the present application has the following advantages:

[0013] The first arc strip and the second arc strip can be disassembled without being moved, thereby avoiding the problem that the first arc strip and the second arc strip cannot be folded, and the first arc strip and the second arc strip do not need to be limited by the material type, thereby further improving the service life.
