Problems solved by technology
[0002] As a walking aid, crutches are widely used among the elderly, the disabled, and the blind. There are many types of crutches, but the appearance is roughly the same. Because people's heights are different, crutches will be manufactured according to the requirements of the human body. The long and short models are designed to meet the needs of people to achieve a certain level of comfort during use. However, sometimes because children buy them as gifts for their parents, the selected length may not be very suitable. It is troublesome to change back and forth, and people will just use them. It may not achieve the desired comfort level, and after a long time of use, people may also have a new standard for the height of crutches. Therefore, how to solve this problem has become the focus of everyone's attention

Embodiment Construction
[0009] A freely retractable crutch has a crutch head (1), a thick hollow tube (2) is welded at the bottom of the crutch head (1), and a linear motor (3) is installed into the thick hollow tube (2) Inside, then put the medium-thick hollow tube (4) into the thick hollow tube (2), so that the linear motor (3) and the medium-thick hollow tube (4) are welded and fixed at the junction, and the A battery (5) is arranged on the top of the thick hollow tube (2), and one end of the battery (5) is connected to the linear motor (3) through a wire, and the other end is connected to the button switch (6) under the crutch head (1); In this way, when people use the freely retractable crutch, they turn on the button switch (6), and the linear motor (3) starts to work, pushing the medium-thick hollow tube (4) to stretch outward, and freely adjust the length of the crutch.

The invention provides a retractable walking stick. A thick hollow pipe is welded to the bottom of a walking stick head, a linear motor is arranged in the thick hollow pipe, a medium-thickness hollow pipe also is arranged in the thick hollow pipe, and the linear motor and the medium-thickness hollow pipe are welded and fixed at the joint point. A battery is arranged on the thick hollow pipe, one end of the battery is connected with the linear motor through a wire, and the other end of the battery is connected with a button switch below the walking stick head in a butt joint mode. Accordingly, when people use the retractable walking stick, the button switch is turned on, the linear motor starts to work, the medium-thickness hollow pipe is pushed to be stretched outwards, and the length of the walking stick is freely adjusted.
