Abstract

The invention provides a wire winding device. The wire winding device comprises a wire winding shaft, an outer cylinder and an inner cylinder. The wire winding shaft comprises a rod part and a head part at one end of the rod part. A first groove is formed on the side face of the head part. The bottom of the first groove is flush with the side face of the rod part. External threads are formed on one end of the side face of the rod part, far from the head part. The outer cylinder comprises a containing hole. A second groove communicated with the containing hole is formed on the side face of the outer cylinder. The wire winding shaft is connected with the outer cylinder and can rotate relative to the outer cylinder. The rod part is contained in the containing hole. The inner cylinder comprises internal threads matched with the external threads. A third groove is formed on the outer side face of the inner cylinder. The third groove and the second groove extend along the same direction. The third groove is below the second groove. The inner cylinder is in the containing hole. The inner cylinder can rotate along with the outer cylinder and can move in an axial direction relative to the outer cylinder.

Description
