The shell 1 comprises a main body 11 and a cover 12 arranged at an opening of the main body 11. A rotation connection mechanism 42 is provided between the shell 1 and the cup 2 for relative rotation of the two.

[0029] The utility model provides a rotating connection structure capable of reducing friction. The rotating connection mechanism enables the shell and the cup to rotate relatively, thereby achieving the effect of reducing the friction on the cup.

[0034] Further, as a preferred embodiment of the present invention but not limiting, the positioning groove 423 is provided with a circular opening 4232 recessed from the opening end surface 23, the circular opening 4232 is between the inner side surface 24 and the outer side surface 25, and is spaced apart from the inner side surface 24 and the outer side surface 25.
