In order to better understand the solution of the present utility model by those skilled in the art, the following description will clearly and completely describe the solution of the embodiment of the present utility model with reference to fig. 1 to 10.

Further, as a specific implementation of some embodiments of the present utility model, as shown in fig. 1, the first connector 22 is disposed on the edge of the cover 11, and the second connector 23 is disposed on the edge of the bottom shell 12. Specifically, the second connection member 23 is located on the rim of the bottom case 12, and the first connection member 22 is located on the rotating rim of the cover case 11 and protrudes inward toward the bottom case 12 so as to be rotatably connected with the second connection member 23 to rotate the cover case 11 with respect to the bottom case 12, thereby opening or closing the bottom case 12.

Preferably, in order to enable the cover 11 to rotate stably, the first connector 22 is integrally formed with the cover 11, so as to strengthen the structural strength of the cover 11 and the first connector 22, and ensure that the first connector 22 can drive the cover 11 to rotate stably.

Further, as a specific implementation manner of some embodiments of the present utility model, as shown in fig. 1, 2, 4, 9 and 10, in order to dispose the second connecting piece 23 on the bottom shell 12, the second connecting piece 23 further includes a second connecting portion 232. In addition, in order to improve structural firmness and rotational stability of the rotating assembly 2 between the cover case 11 and the bottom case 12, it is preferable that two first coupling parts 231 are provided, and one elastic part 231a and one second coupling part 232 are provided on each first coupling part 231.

Specifically, the two second connecting pieces 23 are fixed in the bottom shell 12 at intervals through the corresponding second connecting portions 232, and the two second connecting portions 232 are respectively disposed at two opposite ends of the second connecting piece 23, so as to fix two ends of the second connecting piece 23 simultaneously, and enhance the firmness and the rotation stability of the rotation connection between the cover shell 11 and the bottom shell 12.

In addition, as shown in fig. 2, 4 and 8 to 10, the first connection portion 231 of the second connection member 23 protrudes toward the first connection member 22 to form the elastic portion 231a, and preferably, in order to simplify the overall installation structure, the first connection portion 231 and the second connection portion 232 are vertically arranged in an L shape, so that the elastic portion 231a of the second connection member 23 connected to the first connection portion 231 can abut against the first connection member 22 while the second connection member 23 is fixed to the bottom case 12 by the second connection portion 232, and the first connection member 22 can rotate relative to the second connection member 23 without being blocked by the second connection portion 232.

Further, as a specific implementation manner in some embodiments of the present utility model, as shown in fig. 2, 4, 6 and 9, in order to enhance the damping touch sense of the rotation of the cover 11, a plurality of grooves 221 are respectively provided at opposite ends of the first connecting member 22 abutting against the elastic portion 231a of the second connecting member 23. When the cover 11 rotates relative to the bottom case 12, the plurality of grooves 221 are rotationally engaged with the elastic portions 231a to form a rotational shift feel.
