1. A joystick, comprising:
a stick head;
an actuating component having a first end and a second end opposite to each other, the first end being connected to the stick head, an identification feature being disposed on the second end;
a substrate having a detector used to detect the identification feature and determine motion of the stick head;
a bearing base disposed on the substrate, an opening portion of the bearing base aligning with the detector and the actuating component, the bearing base comprises a first constraining portion connected with the opening portion to form a straight channel;
a resilient recovering component disposed between the substrate and the bearing base; and
a constrainer disposed around the resilient recovering component and movably disposed inside the opening portion in a fit manner, and used to abut against the actuating component in a detachable manner and further to slide inside the straight channel to constrain a straight moving direction of the constrainer, the constrainer comprising a second constraining portion cooperated with the first constraining portion, the first constraining portion and the second constraining portion respectively being a concave structure and a convex structure engaged in a slidably fit manner for linearly sliding the constrainer relative to the bearing base without rotation.
