[0002] A bedside handrail is an auxiliary device in a common medical device, usually installed on one side of the bed, aiming to provide additional support and stability beside the bed to help people in need get in and out of the bed. The design and technology of bedside handrails have undergone years of development to meet the needs of users and improve their functionality. The earliest bedside handrails were usually simple structures made of wood or metal, and their main function was to provide a stable physical support point to help the elderly, disabled or rehabilitation patients move safely. Modern bedside handrails are usually made of aluminum alloy or high-strength plastics, which makes them light and have a strong structure.

[0003] In the prior art, the bedside handrail is installed beside the bed and located at the top of the bed and the bottom of the mattress, so as to complete the installation and use of the bedside handrail. However, for the existing folding structure of the bedside handrail, during the folding process, it is necessary to simultaneously open or close the folding switch with both hands to achieve folding, which leads to inconvenient and inflexible operation during folding. In view of this, we introduce a folding bedside handrail. Content of the Utility Model
