Abstract: A clamping component and an electronic device using the same are provided. The clamping component includes a base and a combining portion. The base is disposed at one side of an accommodating space of the body. The combining portion has a obstructing structure and is disposed at the base. The obstructing structure is exposed to the accommodating space. When the second body is received into the accommodating space, the obstructing structure is elastically deformed to against the second body. The clamping component of the disclosure make the two bodies disassembled and assembled without affecting the appearance, and therefore the aesthetic of the two bodies can be maintained, further, the obstructing structure can improve the convenience in assembling the electronic device. In addition, the risk that the second body is detached from the first body under the external shock or a sudden vibration can be reduced via the clamping component.

Abstract: A cover lifting structure is suitable for a body of an electronic device. The body has a recess. The cover lifting structure includes a first rotating member, a second rotating member, an elastic member and a pushing member. The first rotating member pivoted to the body with a first axis. The second rotating member pivoted to the first rotating member with a second axis. The elastic member is propped against the first and the second rotating members. The first rotating member closes the recess, and the second rotating member contacts against the pushing member in a first state. The first rotating member opens the recess, and the second rotating member moves away from the pushing member in a second state. In a third state, the first rotating member closes the recess, and the second rotating member falls behind a stroke to the first rotating member.

Abstract: A keyboard module includes a key unit, a fixed unit and a cover layer. The key unit includes a plurality of key structures. The fixed unit includes a plurality of position limiting structures, and the position limiting structures are fixed to the corresponding key structures, respectively. The cover layer covers and connects to the key unit and the fixed unit.

Abstract: An abrasive material is fabricated. The material is made of bamboo charcoal. The charcoal has vascular bundles and abrasive particles are uniformly distributed and fixed on inner surfaces of the vascular bundles. Thus, the abrasive material can be used with self-sharpening for grinding, polishing, lubricating, etc.
