[0019] As shown in the figure, this utility model includes a handle cavity 1, a handle body 2, and a transmission bar 3. The handle cavity 1 has a groove 4 to accommodate the handle body 2. The upper back side of the handle body 2 has a transition groove 5. A transition rod 6 is installed in the transition groove 5. The upper transition shaft 7 passes through the handle body 2 and the upper end of the transition rod 6 to form a rotational engagement with the transition rod 6. The two ends of the upper transition shaft 7 are fixed to the two sides of the handle body 2. The lower transition shaft 8 is hinged to the transmission bar 3 and the two ends are fixed to the transition rod 6. The transmission bar 3 extends out of the handle cavity 1. An extension 9 is provided on the circumference of the transmission bar 3. First positioning recesses 10 are evenly distributed on the peripheral wall of the extension 9. A first blind hole 11 is provided in the handle cavity 1 opposite to the peripheral wall of the extension 9. A first spring 12 and a first steel ball 13 are installed in the first blind hole 11. The first steel ball 13 cooperates with the first positioning recess 10. In different open and closed positions, the first steel ball 13 cooperates with different first positioning recesses 10, serving to position and enhance the operating feel. A second blind hole 14 is provided in the adapter rod 6. A second spring 15 and a second steel ball 16 are installed in the second blind hole 14. A second positioning recess 17 is provided at the end of the transmission bar 3 to cooperate with the second steel ball 16. One side of the end of the transmission bar 3 is rounded, and the other side is a right angle. The rounded design makes the transition between the end of the transmission bar 3 and the second positioning recess 17 smoother, and the right angle design positions the opened adapter rod 6, keeping the adapter rod 6 and the transmission bar 3 on the same plane, preventing the adapter rod 6 from being over-opened. Wear-resistant pads 18 are provided between the two side walls of the adapter rod 6 and the groove wall of the adapter groove 5. The upper adapter shaft 7 passes through the wear-resistant pads 18. The wear-resistant pads 18 are made of graphite nylon material and have strong wear resistance while maintaining a certain friction positioning performance. An operating gap 19 is formed between the handle body 2 and the lower wall of the groove 4 to facilitate opening the handle body 2. Figure 2This is a schematic diagram of the handle body 2 in its concealed state in this utility model. When it is necessary to open the handle body 2, first pull the handle body 2 through the operating gap 19. At this time, the handle body 2 and the adapter rod 6, and the adapter rod 6 and the transmission square bar 3 are respectively hinged through the upper adapter shaft 7 and the lower adapter shaft 8. After the adapter rod 6 and the transmission square bar 3 are hinged to coincide and connected, they are positioned by the second steel ball 16 and the second positioning recess 17. After that, rotating the handle body 2 around the coincident axis of the adapter rod 6 and the transmission square bar 3 will achieve the effect of opening the door and window. Of course, even if the axes of the adapter rod 6 and the transmission square bar 3 are not coincident and connected, that is, when the axes of the adapter rod 6 and the transmission square bar 3 are at a certain angle, the handle body 2 can still be rotated and opened. The anti-wear plate 20 passes through the transmission square bar 3 and is placed outside the platform formed by the extension 9. The anti-wear plate 20 is made of stainless steel to reduce frictional damage between the end of the adapter rod 6 and the back wall of the groove 4.

[0020] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
