When opening windows, people must touch the frame or glass, which is inconvenient and smudges the window. This design modifies the handlebar of the window, limiting the handlebar to turn only 90° when pulled from up to down. The handlebar can be easily held to open the window, and serves as the locking and opening mechanism with the braking function. The window can be locked freely in any position.
