[0002] Elevator handrails are a kind of safety auxiliary accessories set in the elevator car for workers to hold on to, which is convenient for elevator passengers to use during walking. The handrails not only provide passengers with an additional support point, so that they can maintain body balance when the elevator moves, and reduce the discomfort that may be caused by the sudden start or stop of the elevator, but also guide passengers to the correct standing position in the elevator. The main functions of the elevator handrail include providing support, guiding direction, providing a sense of security, and facilitating movement. The authorized and published patent application number is CN202010365027.6, which discloses an elevator handrail. The elevator handrail is a conventional safety accessory installed in the elevator car;

[0003] Elevator handrails are installed in elevator cars. Generally, the height of elevator handrails is about 90 to 100 cm, which is approximately at the waist level of adults. It can accommodate children or people of shorter height. However, for children of similar height or slightly higher than the height of the elevator handrails, the height of the elevator handrails is above the chest and shoulders, requiring children to grasp the elevator handrails upwards, which is inconvenient to grasp. The elevator handrails cannot be adjusted in height to facilitate children's grasping. When the elevator handrails are installed in the elevator car, there is a problem that the elevator handrails are not height-adjustable to facilitate children's grasping. For this reason, the present application proposes a retractable elevator handrail. Utility Model Content
