The invention provides a simple mechanical arm and belongs to the technical field of mechanical arms. The simple mechanical arm solves the technical problems that an existing mechanical arm is large in size, complex in structure and inflexible to operate. Thee simple mechanical arm comprises a mechanical arm assembly, a first control mechanism, a front arm body, a second control mechanism, a third control mechanism, a main arm, a fourth control mechanism and a base. The mechanical arm assembly is used for clamping workpieces. The first control mechanism controls the mechanical arm assembly to rotate circumferentially and swing. One end of the front arm body is connected with the first control mechanism. The second control mechanism is capable of controlling the main arm body to rotate. The third control mechanism is capable of controlling the second control mechanism to swing in the vertical plane. One end of the main arm body is fixedly connected with the third control mechanism. The fourth control mechanism is capable of controlling the main arm body to swing in the vertical plane. The base is rotatable, and the fourth control mechanism is arranged on the base. Through the four control mechanisms, the mechanical arm can move flexibly in different planes, the simple mechanical arm is wider in movement range and higher in flexibility, and therefore the working efficiency of the mechanical arm is improved.
