Technical Field

The utility model relates to a supplementary running gear assists device of standing belongs to and helps old mechanical device to make technical field.

Background

According to the national population statistical data of 2018 of the State administration of statistics, the existing population of China is 139538 million people, wherein the population of 65 years old and above is 16658 million, which accounts for 11.9% of the population of the nation, and according to the passing standard of the international society, China already enters an aging society. According to statistics of the national population development plan (2016-. The phenomena of 'left-behind elders' and 'empty nesters' are increasingly serious as the labor force of young and old people is concentrated to large and medium-sized cities along with the rapid development of economy. According to statistics, the daily living ratio of the old people is 18.4 percent, and the living together with the spouse is 39.8 percent. It can be seen that nearly 60% of the elderly do not live with children, and the phenomenon is more prevalent in economically undeveloped and rural areas.
