Abstract: An electronic device includes a frame, a electronic module, and a clip. The frame includes a supporting plate and a first bracket mounted on the supporting plate. The electronic module is located at the supporting plate. A guiding groove is defined in the electronic module. The clip is mounted on the frame and connects the electronic module. The clip includes a mounting portion mounted on the first bracket and a clasp extending from the mounting portion. The clasp can slide along the guiding groove to elastically clasp the first bracket.

Abstract: An exemplary storage rack assembly includes a rack, a cabinet and a mounting bracket fixed to the rack. The cabinet has an elastic component, and the elastic component has a hook exposed from the cabinet. The mounting bracket defines a sliding groove and a receiving channel communicating with the sliding groove. The hook slides along the sliding groove and into the receiving channel. The hook slides along a channel segment of the receiving channel under urging of an applied external force with the elastic component resiliently deforming until the hook reaches the channel segment. The elastic component resiliently recovers and drives the hook down to the end of the channel segment, and the hook resides in the end of the channel segment.

Abstract: A waterproof screw bolt comprising: a head having a bottom surface; and a threaded shank extending from the bottom surface, the threaded shank defining a first ring-shaped groove in the bottom surface around the threaded shank, the head defining a through hole, the through hole running through the head and being in communication with the first ring-shaped groove, the through hole configured to introduce a glue into the first ring-shaped groove.

Abstract: A telephone includes a phone body and an information panel to hold business cards. The information panel is rotatably mounted to the phone body. The phone body defines a receiving hole. The information panel includes a main body, a trigger, and a resilient element. The main body defines a through hole including a first positioning portion located in an inner surface of the through hole. The trigger includes a first end extending through the through hole, a second end received in the receiving hole, and a second positioning portion located between the first end and the second end and matches with the first positioning portion to limit the main body from rotating with respect to the phone body. The resilient element is received in the receiving hole with a first end resisted the receiving hole and a second end resisted on the second end of the trigger.
