[0082] Furthermore, those skilled in the art may also, as needed, set the fixing portion 420 to a conical structure that shrinks in the direction away from the operating portion 410, so that the fixing portion 420 can be inserted into the outer hole portion 211 without being particularly aligned with the outer hole portion 211, thereby facilitating the user's installation of the fixing plug 400.

[0083] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, a protrusion 321 is provided on the side of the free end 320 of the handle 300 facing the fixing portion 420, and the protrusion 321 is adapted to the outer hole portion 211 so that the protrusion 321 is embedded in the outer hole portion 211 (e.g. Figure 7 ), thereby preventing the free end 320 from rotating.

[0084] like Figures 7 to 10 and Figure 13 As shown, in some embodiments of the present invention, the second fixing hole 210 further includes a connecting portion 213 located inside the inner hole portion 212. The connecting portion 213 is connected to the inner side of the cup cover 200 to balance the air pressure inside and outside the cup cover 200 through the second fixing hole 210.

[0085] Furthermore, a notch 214 is provided on the peripheral wall of the communication portion 213 , so that the communication portion 213 is connected to the inner side of the cup cover 200 through the notch 214 .

[0086] Those skilled in the art will appreciate that by providing a notch 214 on the peripheral wall of the connecting portion 213 of the second fixing hole 210 to connect with the inner side of the cup cover 200, foreign matter is effectively prevented from falling from the second fixing hole 210 into the inner side of the cup cover 200 after the fixing plug 400 is pulled out of the second fixing hole 210.

[0087] Return to view Figure 4 and Figure 6 In some embodiments of the present invention, the fixing plug 400 may further include a sealing portion 440 located on a side of the fixing portion 420 away from the operating portion 410 , and the sealing portion 440 is inserted into the communicating portion 213 to seal the communicating portion 213 .

[0088] like Figure 6As shown, the sealing portion 440 is provided with an annular groove (not labeled in the figure), and the liquid holding cup 001 further includes a sealing ring 500 embedded in the annular groove, so that the sealing portion 440 seals the communication portion 213 via the sealing ring 500. Specifically, when the sealing portion 440 is inserted into the communication portion 213, the sealing ring 500 abuts against the peripheral wall of the communication portion 213 and is clamped between the peripheral wall of the communication portion 213 and the sealing portion 440, thereby sealing the communication portion 213.

[0089] Furthermore, the fixing plug 400 can be threadedly connected to the rod-shaped portion 430. Specifically, a threaded hole is provided in the fixing plug 400, and a threaded section is provided at the end of the rod-shaped portion 430 away from the fixing portion 420. This threaded section extends from the inside of the free end 320 through the through hole 301 at the free end 320 and then screws into the threaded hole, thereby securely connecting the rod-shaped portion 430 to the fixing plug 400. This ensures that the fixing plug 400 and the handle 300 can be assembled together.

[0090] Furthermore, the fixing portion 420 , the rod-shaped portion 430 and the sealing portion 440 may be an integrally formed component.

[0091] like Figure 7 and Figure 9 As shown, in some embodiments of the present invention, the connecting member 130 may include three parts, namely, a stopper plate (not labeled in the figure) located outside the cup body 110, a stopper plate (not labeled in the figure) located inside the cup body 110, and a connecting rod (not labeled in the figure) connecting the two stopper plates. In addition, one of the two stopper plates is fixedly connected to or integrally formed with the connecting rod, and the other is clipped or threadedly connected to the connecting rod.

[0092] Furthermore, in other embodiments of the present invention, those skilled in the art may also configure the connecting member 130 as any other feasible member as needed. For example, the connecting member 130 may be configured as a threaded member with a cap (similar to a screw or mushroom), and a threaded hole may be provided on the cup body 110, and then the connecting member 130 may be screwed into the threaded hole on the cup body 110.
