The present disclosure relates to a technical field of electronic external devices, and in particular to a joystick.
For the convenience of next use of users, joysticks need to automatically return to a central position after being used, so that a spring is disposed in each of the joysticks for automatically returning the joysticks. Currently, the spring in each of the joysticks is directly clamped on a main shaft, in a process that the joysticks automatically return to the central position, the main shaft needs to be pushed by the spring for returning an original position, and then the main shaft pushes a corresponding swinging component to return to an original position, the corresponding swinging component is capable of driving a Hall element to transmit a return signal to an electronic product, such that there are relatively more transmission times of the return signal, which results in a relatively larger error in the process that the joysticks automatically return to the central position.

Embodiments of the present disclosure have at least following beneficial effects.
The elastic component directly abuts against the first limiting part of the first swinging component and the second limiting part of the second swinging component, and when the joystick is pushed by an external force in a certain direction, the first swinging component or the second swinging component presses the elastic component and drives a position where the elastic component abuts against the first swinging component or the second swinging component to tilt in a pushing direction. Therefore, in a process that the joystick automatically returns to a central position, the elastic component may directly push the first swinging component or the second swinging component, and the first swinging component or the second swinging component transmits a return signal to an electronic product through a Hall element. Compared with a three-stage signal transmission in the prior art, the present disclosure effectively reduces steps of mechanical signal transmission, which reduces an error in the process that the joystick automatically returns to the central position and is accurate in operation.
