AI Technical Summary
Existing laptop stand designs are difficult to keep in place when folded, which can lead to accidental opening during transport and structural damage.
The design employs a combination of limiting and adjusting mechanisms. Through the cooperation of limiting frame, gears, sliders, and locking blocks, the folded tray is fixed in place, and the length of the support rod is adjusted through the cooperation of telescopic sleeve and positioning plate.
It effectively limits the folded support frame, preventing structural damage caused by accidental opening during transport, and expands the applicability of the device.
