Base-adjustable forearm extension electric firing wearable weapon arm

The invention belongs to the field of outer limb robots, and particularly relates to a base-adjustable forearm extension electric firing wearable weapon arm. Comprising a back frame, a four-degree-of-freedom mechanical arm mechanism connected with the back frame through a sliding rail, and a gun rack mechanism connected with the tail end of the mechanical arm mechanism. The four-freedom-degree mechanical arm mechanism comprises a mechanical arm base, a first freedom-degree mechanism, a second freedom-degree mechanism, a third freedom-degree mechanism and a fourth freedom-degree mechanism. The gun rack mechanism comprises a buffer clamping mechanism and an electric firing mechanism, the buffer clamping mechanism is used for clamping a gun and buffering during firing, and the electric firing mechanism is used for electric firing of the gun. According to the invention, firepower suppression in multiple environments can be realized, better man-machine motion collaboration is achieved, and the fighting capacity of
