The invention provides a polygonal extension fitness frame and a corresponding comprehensive fitness combination frame. The polygonal extension fitness frame comprises a plurality of first-layer crossbeams, at least one layer of outer-layer crossbeams, a plurality of layer-to-layer transition beams, a plurality of stand columns and various fitness mechanisms or instruments, wherein the two ends of each first-layer crossbeam are located on a first-layer circumference by taking the center of the polygonal extension fitness frame as the circle center, so that one side of an equilateral polygon is formed, and the endpoints of one side are located on the first-layer circumference; the two ends of each outer-layer crossbeam are located on the outer-layer circumference outside the first-layer circumference and correspond to vacant positions formed because the first-layer crossbeams are separated; the crossbeams in all layers are connected in series through the layer-to-layer transition beams; one end of each stand column is fixed to a base or the ground, and the other ends of the stand columns are connected with connecting points among the first-layer crossbeams, the outer-layer crossbeams and the layer-to-layer transition beams; the fitness mechanisms or instruments are arranged among the first-layer crossbeams or the outer-layer crossbeams or the layer-to-layer transition beams or the stand columns. More detailed function division is carried out, more people can be allowed to take exercise without mutual influences, and security, privacy, interestingness and comfort of exercise are increased.

The golf head material is prepared from the following raw materials: vanadium powder, aluminum powder, chromium powder, nickel powder, manganese powder, iron powder and titanium powder. It has good elastic properties and hardness properties, and also has good tensile properties.

The invention discloses a three-freedom-degree coaxial output mechanism containing wire transmission. The three-freedom-degree coaxial output mechanism comprises a vertically-arranged center transmission shaft, and the center transmission shaft is supported through a horizontally-arranged base and driven by a first motor; the center transmission shaft is sequentially provided with a first driving arm, a follow-up support, a second hollow shaft and a second driving arm from top to bottom; the first driving arm is fixedly installed at the top of the center transmission shaft; the follow-up support is rotationally installed on the second hollow shaft, a second hollow shaft driving wheel is fixedly installed on the second hollow shaft, and driving between follow-up wheels fixedly installed on a movable platform rotating shaft is achieved through wires; and the second driving arm is fixedly installed on a third hollow shaft, the third hollow shaft is rotationally connected to the center transmission shaft, the second hollow shaft is in transmission connection with a second motor through a gear, and the third hollow shaft is in transmission connection with a third motor through a gear. The rotational inertia of a motion part of the three-freedom-degree coaxial output mechanism is small, and the high-speed capacity and the high-accelerated-speed capacity are achieved.
