Abstract: A packaging box includes a body, a first and a second bottom plate. The body has an accommodating space and a bottom opening and includes a first and a second side plate opposite to each other. The first bottom plate is foldably connected to the first side plate and has a first bottom part for covering the bottom opening and a main inserting part foldably connected to the first bottom part. The first bottom part has a slit. When the first bottom part covers the bottom opening, the main inserting part is inserted into the bottom opening. The second bottom plate is foldably connected to the second side plate and includes a second bottom part and a tongue. The second bottom part is superposed on the first bottom part. The tongue is inserted into the slit, so that the second bottom plate is detachably fixed to the first bottom plate.

Abstract: A plurality of artificial feathers connects to a plurality of stems and a base portion to form a shuttlecock. Each of the artificial feathers includes a connecting portion and a resistance portion. The connecting portion connects to one of the stems. The resistance portion connects to the connecting portion, and the resistance portion includes a plurality of low-wind-resistance areas and a high-wind-resistance area. The low-wind-resistance areas are surrounded by the high-wind-resistance area.

Abstract: Methods and devices for connecting to multiple interfaces are provided. The method includes: receiving, by a client managing unit, a first data and a connection request transmitted from a first client device, wherein the connection request is used to request to connect to a first remote device; determining, by a remote device managing unit, an interface protocol of an interface controller of the first remote device according to the connection request, and transmitting the first data to an interface protocol processing unit corresponding to the interface protocol; and adding, by the interface protocol processing unit, a header corresponding to the interface controller of the first remote device to the first data and transmitting the first data adding the header to the first remote device through the interface controller.

Abstract: A cushioning structure includes a main body and two first cushioning elements. The first cushioning elements clip two ends of the main body, respectively, to form a containing space. Each of the first cushioning elements has two symmetrical cushioning portions for sandwiching the main body. Each of the cushioning portions has an inclined plane extending inward from an edge of the main body.
