Disclosed is a mechanical arm (200), which is connected to an actuating mechanism (100) and drives the action of the actuating mechanism (100). The mechanical arm comprises a first connection arm (1) and a second connection arm (2) which are connected to the actuating mechanism (100), a driving mechanism (30) which drives the action of the first connection arm (1) and the second connection arm (2), and a base assembly (40), wherein the first connection arm (1) comprises a first four-link mechanism (10) and a rocker arm mechanism (18); the second connection arm (2) comprises a support seat (21) and a second four-link mechanism (20) fixed on the base assembly (40); and the driving mechanism (30) comprises a first driving assembly (32) for driving the action of the first four-link mechanism (10), and a second driving assembly (34) for driving the action of the second four-link mechanism (20). By arranging the first four-link mechanism (10) and the second four-link mechanism (20) to drive the action of the actuating mechanism (100), the driving action of the first four-link mechanism (10) with the first driving assembly (32) and the driving action of the second four-link mechanism (20) with the second driving assembly (34), the mechanism arm (200) drives the action of the actuating mechanism (100), the actions of the first four-link mechanism (10) and the second four-link mechanism (20) are independent from each other and will not interfere with each other, and the structure is simple. |
