Problems solved by technology
[0002] With the improvement of living standards, people pay more and more attention to the emergency solutions for the personal safety of children and the elderly. However, ordinary pens have single functions and cannot meet the living needs of contemporary people.
In order to enable guardians to keep informed of their children's situations at school or accidents caused by parents who are unattended at home, and to carry out timely rescue of accidents, people currently propose crutches with self-powered positioning and calling for help, such as Chinese invention patents , Application Publication No.: CN204654021U, it only works when an accident occurs to the elderly and the disabled, and lacks such similar daily necessities for children. At the same time, this kind of crutch is inconvenient to carry for the elderly and disabled people who are used to traveling in wheelchairs. In order to solve the above problems, it is urgent to design a self-powered location calling for help signature pen
