Sports education refers to education by means of physical activities, with transliteration into physical education, referred to as sports for short. With the expansion of international interaction, the scale and level of sports business development is an important mark for measuring the development progress of a country and a society, and becomes an important means for foreign exchange and cultural communication of the country. Sports can be divided into categories such as mass sports, competitive sports, school sports, traditional ethnic sports, and the like. Including a plurality of factors such as sports culture, sports education, sports activities, sports competitions, sports facilities, sports organizations, sports science and technology, sports economy and the like. Physical education is a purposeful and organized educational process performed according to certain plans and curriculum standards. The physical education is participated in by teachers and students, and the task is to teach students physical knowledge, technique and skill, strengthen their physique, cultivate their moral, will, quality, etc. It is the basic form of school sports realization, and is one of the implementation ways of sports objectives.

The physical education includes multiple training devices, and the arm strength lifting device is one of the multiple training devices. However, the existing general method is to adopt a dumbbell or a spring mechanism, but the exercise device has simple exercise mode and single function, cannot arouse the exercise interest of students, and has poor arm strength improving effect.

Chinese patent CN 106984005B provides a multiple hoisting device of arm strength for sports teaching for this reason, which comprises a top plate, stand and bottom plate seat, the stand is fixed in on the bottom plate seat, the upper end of stand is supported through many diagonal braces and is fixed with the roof, the cover is equipped with external body on the stand, the upper portion of external body is rotated the cover and is equipped with and rotates the cover, the other end connection of the side stretch cord of rotating the cover is equipped with the second bracelet, still be equipped with spherical piston in the inboard middle part shear thickening fluid cavity of stand, spherical piston's upper and lower both ends are equipped with upper connecting rod and lower connecting rod respectively, the lower extreme of connecting rod is equipped with the balancing weight in the balancing weight cavity, the upper end connection of upper connecting rod is equipped with wire rope, the bottom of roof is equipped with the fixed pulley that is. This multiple hoisting device of arm strength for sports teaching has following function: 1, a user places a balancing weight at the lower end of a lower connecting rod, pulls a steel wire rope through a first bracelet, and the steel wire rope drives an upper connecting rod, a spherical piston and the lower connecting rod to move upwards together, so that the effect of changing arm force pulling difficulty according to the balancing weight is achieved; and 2, the user holds the second hand ring and swings, the rotating sleeve is driven to rotate by taking the external body as the center through the elastic rope, and the arm strength of the user is exercised by the elasticity of the elastic rope.
