The cantilevered structure allows the second part to extend on one side without conflicting with other components of the main body 123, making the connection of the card holder 120 more flexible. In addition, the cantilevered structure can provide support and connection functions in a limited space while maintaining a small size and volume.

[0059] In some embodiments, the first portion is provided with a first through slot 127a and a second through slot 127b, which penetrate the first portion along the second direction and are respectively provided on opposite sides of the latch 121. Figure 6 The first part includes a latch 121, a first through slot 127a and a second through slot 127b, which are respectively arranged on opposite sides of the latch 121. In combination with the above-mentioned embodiment, a first positioning slot 134a and a second positioning slot 134b are arranged on the base 130, and the first positioning slot 134a and the second positioning slot 134b are connected by a slot connecting portion 135, and the slot connecting portion 135 extends into the installation cavity 125. The first through slot 127a and the second through slot 127b on the card holder 120 can correspond to the slot connecting portion 135 on the base 130, so that the card holder 120 can rotate relative to the base 130. In addition, the first through slot 127a and the second through slot 127b also have guiding and positioning functions, guiding the latch 121 to move on a specific track, so as to achieve more precise position control.

[0060] In some embodiments, the card holder 120 further includes a first hook portion 128a and a second hook portion 128b, which are configured as cantilevered arms connected to the main body 123 and extending along a first direction, and are respectively disposed on opposite sides of the mounting cavity 125, and the first direction is perpendicular to the disk body 140; the end of the rod 110 is inserted into the mounting cavity 125 and is provided with a matching groove 113, and the first hook portion 128a and the second hook portion 128b are disposed opposite to each other and engage with the matching groove 113. Please refer to Figure 5 The first hook 128a and the second hook 128b of the socket 120 extend out of the main body 123 along a first direction, and the first direction is the up and down direction in the figure. The first hook 128a and the second hook 128b are respectively located on both sides of the installation cavity 125, and are symmetrically arranged along the central axis of the socket 120. The ends of the first hook 128a and the second hook 128b are respectively provided with a first convex hook 129a and a second convex hook 129b for engagement, and the first convex hook 129a and the second convex hook 129b are opposite to each other at the front and the width gradually decreases from bottom to top. In some embodiments, the rod member 110 includes a rod core 111 and a rod sleeve 112. A mating groove 113 is provided at the end of the rod core 111.
