Abstract: An non-loosening and vibration-proof expanding screw includes a screw cap defining a receiving cavity, and a rod body connected to the screw cap. The rod body defines a hollow cavity, a sealing ring, and an air inlet pipe. The sealing ring includes a main body with a receiving hole and an internal ventilation pipe. The internal ventilation pipe includes interconnected first and second holes. The air inlet pipe is received in the first hole and gas under pressure can be introduced into the hollow cavity through the second hole. Thus the expanding screw can be inflated to expand and thereby lock the expanding screw and a securable object together, or be deflated to allow its release.

Abstract: An electronic stylus includes a body, a touching end and a charging end. The touching end and the charging end are arranged at opposite ends of the body. A charging terminal is located in the charging end, the charging terminal being configured for plugging into an external power source. A driving assembly is arranged on the body for driving the charging terminal to extend or retract through the charging end.

Abstract: A method for affixing adhesive films to a main board is provided. The main board includes a main body and a shield. The shield includes a first shield and a second shield. The second shield defines openings. When the second shield is attached to the main body, components of the main body are confined within the openings, respectively. The method includes: first absorbing a single adhesive film to an electrostatic absorbing film. Then, stamping the electrostatic absorbing film and the single adhesive film to form adhesive films that have substantially the same shape and arrangement as the openings. Next, aligning the electrostatic absorbing film with the first shield and affixing the adhesive films to the first shield. Then, removing the electrostatic absorbing film from the first shield. And, assembling the first shield to the second shield.

Abstract: An electronic device and a slide switch are disclosed. The slide switch includes a main body, a slider, a rotary plate rotatably connected to the main body, and a rotary arm. The main body includes a fixing space, a channel, and a first contact member protruding from a bottom of the fixing space. The slider is movable between a first position and a second position within the channel. The rotary plate includes a lateral surface and a second contact member protruding from the lateral surface. Two ends of the rotary arm are respectively connected to the slider and the lateral surface. When the slider is located in the first position, the first contact member spaces from the second contact member; when the slider is moved to the second position, the rotary arm rotates the rotary plate causing the first contact member to contact the second contact member.
