Abstract
The threading device includes a thread-pushing rod, a thread-transmitting rod, a first transmission subassembly, a second transmission subassembly, and a first pushing member. The thread-pushing rod defines a first through hole. The thread-transmitting rod is mounted on the thread-pushing rod and defines a second through hole. The first transmission subassembly includes a first rotating member and a spur gear mounted on the first rotating member. The second transmission subassembly includes a second rotating member and a second spur gear mounted on the second rotating member. The second spur gear meshes the first spur gear. A passage is defined by the first rotating member and the second rotating member. A tangent of the passage is aligned with the first through hole and the second through hole. The first pushing member is coupled to the first rotating member and configured to rotate the first rotating member.
