The skipping rope is taken as a body-building sport popularized by the whole people, is simple and easy to implement, and is less bound by weather of time and place compared with most sports; the body-building cost is low, and expensive body-building equipment is not needed; the health care tea has obvious health care effect and even has extremely strong health care effect on people at different ages, so the health care tea is popular among the general public. For people who increasingly pursue stronger physical fitness, such as athletes, fitness enthusiasts, sports careers and the like, the traditional skipping rope cannot meet the requirement of exercise intensity. For this reason, heavy rope skips gradually enter their field of view. Compared with the traditional thin rope, the weight of the heavy rope can reach 1.5KG, which is about 10 times of that of the traditional skipping rope, and the diameter can reach 20mm, which is about 2-3 times of that of the traditional skipping rope.

The greater mass and diameter of the heavy rope provides greater resistance and the exercise intensity increases. However, the traditional handle rope skipping device for operating the heavy rope has high requirement on the strength of the wrist, and is not suitable for most people.

When the heavy rope is controlled, the gravity center of the rope changes obviously in real time, a user only holds the handle rope skipping device by hand and cannot control the rope skipping device easily, and rope skipping speed is limited. The data suggest that rope skipping speed is one of the main factors in determining rope skipping training intensity and effective muscle group training.

When using traditional handle rope skipping ware to control heavy rope, the fag end in the handle forms approximate 90 contained angle with the rope, is unfavorable for the rotation of rope end, easily appears twisting the rope phenomenon, has also increased its control degree of difficulty simultaneously, and the scope and the quantity of the muscle crowd of taking exercise are also less.

Therefore, the existing rope skipping device is still to be improved and developed, so that the rope skipping device is more convenient to operate and control the heavy rope.
