The invention discloses an electrostatic spinning device, a spinning method and an application of a steering gear, and belongs to the field of electrostatic spinning. The electrostatic spinning device is characterized in that the device comprises an electrostatic spinning injection device and a motion adjusting device, an injection needle of the electrostatic spinning injection device moves in a space coordinates system by the motion adjusting device and is supported by the steering gear, and the steering gear vertically moves along with the motion adjusting device. The electrostatic spinning device has the advantages that a space moving deice and a device for changing shapes of nano-fibers are integrated, excessive lines cannot added into the space, and multi-dimensional change of positions and shape change of the nano-fibers can be achieved by the same device.
