The invention discloses a palletizer provided with a ten-rod four-freedom-degree controllable mechanism type moving mechanical arm. The palletizer comprises a moving operation platform, a linear driver, driving rods, supporting frames, connecting rods, a motor and a grasping hand. The linear driver and the first, second and third driving rods are installed on the moving operation platform. One end of the first supporting frame is connected with the linear driver and the first driving rod. The other end of the first supporting frame is connected with the first connecting rod and a first pull rod. The other end of the first connecting rod and the other end of the first pull rod are connected with the second supporting frame. The other end of the second supporting frame is connected with a second pull rod and the third connecting rod. The other end of the second pull rod and the other end of the third connecting rod are connected with the third supporting frame. A multi-freedom-degree controllable mechanism with the motor installed on the moving operation platform is adopted for replacing a serial mechanism with an original motor installed on the mechanical arm, and therefore the problems that an original mechanical arm is large in weight and poor in dynamic property are solved; the moving operation mechanical arm technology is applied to the palletizer, and therefore various mechanical palletizers and other engineering machines can be manufactured.
