The bending mechanism 100 includes a first support 110, a first lifting cylinder 123, a bending assembly 120, and a cutting assembly 130. The cutting assembly 130 is mounted on the first support 110 and is used to cut the wire to separate it into an incoming section and a section to be wound. The first lifting cylinder 123 is mounted on the first support 110, and the bending assembly 120 is mounted on the output end of the first lifting cylinder 123. The bending assembly 120 is used to bend one end of the section to be wound at a preset angle.
