The invention discloses a mechanical arm convenient to move. The mechanical arm convenient to move comprises a base, a stand column, shaft joints and a control device, wherein every two shaft joints are rotationally connected, and a telescopic control mechanism is at the position of the joint of every two shaft joints; a driving control module, an executing control module, the telescopic control modules, an alarming control module and a center control module are arranged in the control device; the alarming control module is connected with an alarming mechanism, and the driving control module, the executing control module, the telescopic control modules and the alarming control module are all connected with the center control module. According to the mechanical arm convenient to move, due to the fact that each telescopic control mechanism is arranged between every two shaft joints, the telescopic function of the shaft joints can be achieved through the telescopic control mechanisms, carrying and moving of the mechanical arm are facilitated, the problem that the mechanical arm is difficult to move is well solved, it is also effectively avoided that the mechanical arm is damaged in a collision manner in the moving process, a good protection effect is achieved for the mechanical arm itself, and therefore the service life of the mechanical arm is effectively prolonged.
