[0039] Optionally, the inner wall of the groove 21 is an arc surface.

[0040] In this embodiment, the inner wall of the groove 21 is an arc surface, which can be a part of a circular arc surface or a part of an elliptical surface, thereby avoiding the occurrence of edge structures inside the groove 21 to prevent scratching the outer wall of the needle 100 during the glue wiping process.

[0041] Optionally, the shape surrounded by the arc-shaped structure between the two grooves 21 matches the shape of the outer wall of the needle 100.

[0042] Generally, the outer wall of the needle 100 is a cylindrical surface, and the two grooves 21 can form a complete circle in opposition, thereby ensuring that the arc-shaped structure can be in complete contact with the circumferential outer wall of the needle 100, thereby completely removing the residual glue. Of course, if the shape of the outer wall of the needle 100 changes, for example, the outer wall of the needle 100 is an elliptical cylindrical surface or other shapes, then the shape surrounded by the arc-shaped structure between the two grooves 21 can be optimized to match the shape of the outer wall of the needle 100.
