In the actual use process, more than two screwing members 5 or screwing areas 6 are generally arranged to be matched with the engineering of the palm of the human body, so that the friction force between the fingers or the palm of the operator and the outer surface of the cover body 1 is increased, and the rotation of the cup cover is driven. The cup cover and the fluid supply cup are connected together in a rotating or rotating manner, and the specific connection manner can be a manner of a spiral wedge and a spiral slot, a manner of an internal thread and an external thread, a manner of a plurality of internal thread sections and a plurality of external thread sections, and other manners of course can be adopted, which are not described herein.

In another preferred embodiment of the present utility model, as shown in fig. 2-13, the screwing member is a protrusion 8 on the side wall, the protrusion 8 is fin-shaped, the protrusion 8 extends along the outer surface of the side wall 4, the extending length can be determined according to the need, as shown in fig. 13, the extending direction can extend along the circumferential direction of the side wall 4, and an operator can rotate by holding the top end of the fin in the circumferential direction with a finger. Or may extend from the side edge 3 in the direction of the tubular connection 2, and may be arranged according to the custom of the user. When the fin-shaped mode is adopted for arrangement, as shown in fig. 2, 3, 4 and 5, when a user applies pressure to the fin part, the cup cover and the fluid supply cup are fastened step by step, when the cup cover is connected with the fluid supply cup and is fastened thoroughly, the pressure is continuously applied to the fin part, the fin part can generate slight deformation, the mechanical information with touch sense, which is fed back to an operator, of which the cup cover is locked, is not needed to be observed, the operator can judge that the cup cover is firmly connected with the fluid supply cup, and the next operation can be performed more quickly.

More preferably, as shown in fig. 3, 4 and 5, the standing portion 9 of the fin-shaped protrusion 8 is adapted to the finger or palm of the human body, and the specific shape of the standing portion 9 can be set according to the operation habit of the user. By adopting the mode of the vertical 9, the touch feeling of an operator during operation can be further improved, and the deformation amount of the vertical 9 can be set according to the operation habit of the operator, so that the use experience of the operator is improved.

Of course, two or even number of screwing members 5 may be uniformly arranged on the outer surface of the side wall 4 according to the operation habit of the operator as shown in fig. 3 to 13; or three or an odd number of screwing members 5 are uniformly arranged on the outer surface of the side wall 4. Generally, two, three or four knob members 5 are provided on the cover 1 to meet the user's requirement, and when only one screwing member 5 is provided, the situation that the stress of the cup cover is uneven is easily caused when an operator specifically operates the cup cover, and specifically, at least two screwing members 5, namely, fin-shaped protrusions 8 are generally provided.
