Furthermore, the design of the annular boss 17 provides additional protection for the base 10, preventing direct impacts and wear, and ensuring the durability of the base 10 in harsh environments.

[0022] Furthermore, the flat seat cover 7 has a cover hole 20 corresponding to the positioning through hole 12. The flat seat cover 7 is fitted onto the base 10, and the handle connecting end 3 of the flat seat positioning member 8 passes through the cover hole 20 and connects to the handle body 1. Specifically, in this embodiment, the cover hole 20 not only ensures a stable connection between the handle and the flat seat cover 9, but also enhances the rotational stability and smoothness of the handle through precise matching.

[0023] Furthermore, a positioning groove 21 is formed on the base 10, and a positioning component is set in the positioning groove 21. The positioning component includes a positioning bead 22 and a positioning spring 23, with both ends of the positioning spring 23 abutting against the positioning bead 22 and the groove wall of the positioning groove 21, respectively. Specifically, in this embodiment, the positioning bead 22 allows the handle to remain stable at different angles, while the positioning spring 23 provides the necessary elasticity to ensure that the positioning bead 22 can fit tightly against the positioning groove 21, thereby achieving precise positioning of the handle. This design not only improves the flexibility of the handle but also enhances the reliability of the overall structure. In actual use, even under frequent operation or external force, the positioning component can ensure that the handle will not easily loosen or shift, thus ensuring the long-term stability of the door and window handle.
