The inner shell 110, the movable unit 200 includes an outer shell 210, a sliding plate 220 and a handle 230, the sliding plate 220 is fixedly installed inside the outer shell 210, the handle 230 is fixedly installed on the outer shell 210, the outer shell 210 is located on the outside of the inner shell 110, the sliding plate 220 is located on the inside of the inner shell 110, the sliding plate 220 contacts the pulley 115, and the sliding plate 220 can drive the pulley 115 to roll when it moves. The sliding plate 220 can drive the constant force spring 116 to expand, and the constant force spring 116 is supported on the sliding plate 220.

[0034] The bracket in this application can be used in a touch screen all-in-one machine as a bracket for the touch screen, and is used to adjust the height of the touch screen at will. The bracket includes a fixed unit 100 and a movable unit 200. The fixed unit 100 includes a fixedly connected base 130 and an inner shell 110. The base 130 is a counterweight base.

After theoretical calculation and experimental verification, it is only necessary to apply a force of approximately 2.8 kgf cm to break the balance between the friction and tensile forces. Pulling the handle 230 upward can raise the bracket, and pulling the handle 230 downward can lower the bracket, thereby achieving the purpose of adjusting the bracket height at will, which is very convenient to operate. The bracket in this application can be used in public services such as supermarkets, medical institutions, educational institutions, etc. By using the bracket's lifting function, the height of the touch screen all-in-one can be changed, making it convenient for various people to use.
