The junction between the two screens is the secondary functional area 22; the width of the screen body is not too wide, so that when the curling module 2 is curled on the surface of the scroll 1, the two ends of the curling module 2 are warped, namely, gaps between different curling turns at the two ends of the curling module 2 are relatively large, and the curling module cannot be closely attached.
It will be appreciated that the spool 1 may also comprise two main body areas 11 and three suction areas 12; that is, the suction region 12 is provided between the two body regions 11, and the suction region 12 is also provided on the side of each body region 11 away from the other body region 11. Similarly, crimping module 2 includes two primary functional areas 21 and three secondary functional areas 22; that is, a sub-functional area 22 is provided between two main functional areas 21, and a sub-functional area 22 is also provided on a side of each main functional area 21 remote from the other main functional area 21.
The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
