Universal ball connecting device of elasticity with adjustable

The utility model discloses an universal ball connecting device of elasticity with adjustable, here device mainly includes two parts, and some is put for universal football shirt, and there are four ARC groove on universal ball surface, another part is the elastic compression device, and this elastic compression device is divided into two hydro -cylinders of size can its compression pretightning force of each self -interacting, and along with the pretightning force of difference is adjusted the alongside uninterrupted loading and is put different flexibility ratios, little hydro -cylinder is responsible for giving universal ball to pass power and is realized the lock and die that limit effects such as its amplitude of fluctuation, big hydro -cylinder is the servo -cylinder, because this device is less at straight -line distance, has limited the length of spring, has consequently added a dynamics that the spring was made up a deficiency to the servo -cylinder at the side. Can let the nimble reliable realizatio
