The utility model discloses a four-axis mechanical arm of a parallelogram connecting rod structure. The four-axis mechanical arm comprises a base, a rotating disc, four driving motors and three parallelogram connecting rod mechanisms. A rotating disc is arranged on the base, a first parallelogram connecting rod mechanism is arranged on the rotating disc, a second parallelogram connecting rod mechanism is connected with the tail end of the first parallelogram connecting rod mechanism, a third parallelogram connecting rod mechanism is arranged at the tail end of the second parallelogram connecting rod mechanism, and a first driving motor is arranged on the base. The first driving motor drives the rotating disc to rotate, so that the manipulator horizontally rotates, the second driving motor and the third driving motor drive the manipulator to pitch and move back and forth, and the fourth driving motor drives a clamping jaw of the manipulator to clamp and loosen. The four-axis mechanical arm is low in overall we
