Abstract: An electronic device includes a main body, a slot formed on a side of the main body, and a tray unit received in the slot. The tray unit includes a cover, a supporting base, a shaft, and a waterproof member. The supporting base is configured to receive an external card. The shaft pivotally connects the cover with the supporting base, and the supporting base is rotatable with respect to the cover along the shaft. The waterproof member is disposed on the cover. When the tray unit is received in the slot, the waterproof member abuts the main body of the electronic device.

Abstract: A holder and a sucker thereof for mounting onto the surface of an object are provided. The sucker has an adhesive layer and a deformable body which is disposed on the edge of the adhesive layer. The holder further includes a rod and a locking module. An end of the rod is connected to the sucker. The locking module is disposed on the sucker and is adapted to lift the rod to form a low pressure space. Thus, the holder and the sucker can be positioned onto the surface of the object.

Abstract: A holder for sustaining a handheld electronic device is provided. The holder includes a sucker and a positioning device. The sucker has a central and peripheral portion. The positioning device, which is disposed on a side of the sucker, comprises a housing, a ball, a clamping assembly and a rod. The housing is disposed on the sucker and has a receiving space for the ball and the clamping assembly. The rod has a first end connecting to the central portion of the sucker and a second end extending towards the receiving space. When the rod is led to position the sucker onto an object, the clamping assembly is adapted to restrict the ball simultaneously.

Abstract: A method for making a sole includes the steps of material preparing, placing material in a mold, vacuuming the mold, foaming the material inside the mold and opening the mold to present the product. A raw material for making the sole and a colored material are prepared and the raw material is sliced and cut into sole-shaped pieces. Then the sole-shaped pieces and the colored material are placed in a mold. After the bottom mold and the top mold are combined in an air-tight manner, air is completely drawn out of a chamber. When heat is supplied to allow the sole-shaped pieces to combine with the colored material, opening the mold will present a sole with clear separation between the color of the sole body and the area where the colored material is located.
