[0036] The installation and use method of the handle lock for a narrow-frame flat-opening glass door of the present invention is as follows: a lock tongue box 1 is installed on a door frame 100, a lock tongue 2 is installed on the lock tongue box 1, a lock body 3 is installed on a sash frame 200, a handle 4 is installed on the sash frame 200 and is located on the side of a glass mounting groove 300 of the sash frame 200, and the glass door is installed in the glass mounting groove 300 of the sash frame 200. When the glass door is opened, the lock tongue 2 is retracted and hidden in the lock tongue box 1. When the glass door is closed, when the lock hole 73 of the lock hole slider 7 of the lock body 3 is aligned with the lock tongue 2, the second magnet 77 of the lock hole slider 7 magnetically attracts the first magnet 22 of the lock tongue 2 to suck the lock tongue 2 out of the lock tongue mounting hole 12 of the lock tongue box 1 and extend it into the lock hole 73 of the lock hole slider 7 to lock the glass door; when opening, the handle 6 of the handle 4 is turned downward to drive the driving gear 91 to rotate The first driven gear 92 and the second driven gear 93 are driven to rotate synchronously, and the second driven gear 93 drives the rack 81 to slide down and drive the lock hole slider 7 to move downward, so that the lock tongue 2 slides out under the guidance of the guide inclined wall 731 of the lock hole 73, so as to open the handle lock. After the lock tongue 2 slides out of the lock hole 73, it is reset and retracted and hidden in the lock tongue box 1 under the pull of the first spring 24. When the handle 6 is released, the handle 6 will be reset under the drive of the torsion spring 94, and the lock hole slider 7 will slide up and reset under the drive of the second spring 71. It is suitable for installation in a narrow-frame flat glass door without opening an opening on the glass door. At the same time, it is convenient to install the lock tongue 2 and the lock tongue box 1 on the door frame, and the lock body 3 and the handle 4 on the fan frame. The installation position of the lock tongue 2 can be fine-tuned left and right, and the installation position of the lock body 3 can be fine-tuned up and down.

[0037] In addition, it also has the characteristics of indoor anti-locking and outdoor emergency unlocking.
