[0007] A walking aid suitable for the elderly comprises a base, wherein the outside of the base is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a worm, the outside of the worm is meshed with a worm wheel, the inside of the worm wheel is fixedly connected to a hollow tube, the inside of the hollow tube is threadedly connected to a screw, the top of the screw is fixedly connected to a support platform, an armrest is installed on the top of the support platform, and an arm placement plate is installed on the top of the support platform and on one side of the armrest. By starting the servo motor, the servo motor drives the worm to rotate, and the rotation of the worm drives the worm wheel outside it to rotate. The rotation of the worm wheel drives the hollow tube to rotate, and the rotation of the hollow tube drives the screw to rise and fall inside the hollow tube, thereby adjusting the height position of the support platform. When walking, the elderly hold their hands on the outside of the armrest and place their arms on the outside of the arm placement plate, so that the device can be suitable for elderly people of different heights.

[0008] Preferably, a storage drawer is slidably connected to the interior of the support platform, so that the elderly can place their belongings inside the storage drawer when traveling.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a walking aid suitable for the elderly, referring to Figure 1 and Figure 3, including a base 1, a servo motor 2 is fixedly connected to the outside of the base 1, a worm 3 is fixedly connected to the output end of the servo motor 2, a worm wheel 4 is meshed on the outside of the worm 3, a hollow tube 5 is fixedly connected to the inside of the worm wheel 4, a screw 6 is threadedly connected to the inside of the hollow tube 5, a support platform 7 is fixedly connected to the top of the screw 6, an armrest 8 is installed on the top of the support platform 7, an armrest plate 9 is installed on the top of the support platform 7 and on one side of the armrest 8. By starting the servo motor 2, the servo motor 2 drives the worm 3 to rotate, and the rotation of the worm 3 drives the worm wheel 4 outside it to rotate. The rotation of the worm wheel 4 will drive the hollow tube 5 to rotate, and the rotation of the hollow tube 5 will drive the screw 6 to rise and fall inside the hollow tube 5, thereby adjusting the height position of the support platform 7. When walking, the elderly hold their hands on the outside of the armrest 8 and place their arms on the outside of the armrest plate 9, so that the device can be suitable for elderly people of different heights.
