[0031] The rotating disc 300 is rotationally connected at the front end of the box body 100. The second opening 310 is coaxial with the opening 110 and has a larger diameter than the opening 110. Two second fixing plates 320 are symmetrically installed on the side wall of the rotating disc 300. The knob 330 is rotationally connected to the side wall of the second fixing plate 320. The knob 330 has a limiting structure. When the knob 330 does not need to be rotated, the limiting structure causes the knob 330 to be locked to prevent the rotation of the knob 330.
