[0002] Traditional door and window structures with handles usually have a mounting groove on the front of the door and window carrier, and the handle assembly is installed in the mounting groove on the front of the door and window carrier. The handle assembly drives the latch to move, so that the door and window carrier can lock and open the door.

[0003] However, in some use cases of door and window carriers, it is not necessary to lock or open the door, such as transparent doors and windows similar to screens, which only need to be temporarily fixed. For such use cases, the front of the door and window carrier is required to be relatively simple and without bumps and depressions;

[0004] In summary, the prior art has at least the following technical problems:
