Abstract: A positioning method for orthodontic appliance and structure, mainly provided with base units molded by plastic injection. During the fabricating process, a crossed reference line is first drawn on a dental mold of the patient, after heating, the orthodontic appliance is embedded to the base unit, and a flexible member is used to bind and fixedly position the orthodontic appliance. Each of the aforementioned base units together with the orthodontic appliance is attached to the dental mold, and then light curing composite resin is attached to each of the base units. Accordingly, after applying an adhesive layer to each of the orthodontic appliances, each of the series connected base units together with the orthodontic appliances bound to the base units is directly attached to the respective teeth portion of the patient requiring straightening, thereby enabling fitting of orthodontic appliances to be more convenient and providing a more efficient fabricating process.

Abstract: An assembly and disassembly device for a display monitor and a method are disclosed. The assembly and disassembly device of the present invention is used to assemble the display monitor to a seat and to disassemble the display monitor from the seat body. The assembly and disassembly device of the present invention comprises a lockup portion connected to the seat body and a framework portion connected to the display monitor. The lockup portion has at least a locking body, and the framework portion has a connecting body. The fastening body has an opening and a guiding slot, and the opening is connected with the guiding slot. When the locking body moves from the opening to the guiding slot, the lockup portion can be securely fastened to the framework portion, thereby installing the display monitor to the seat body.

Abstract: The invention provides an input/output port (I/O port) switch structure of an electronic device. The electronic device comprises a motherboard, and an opening is installed on a predetermined position of the electronic device. The switch structure is installed on the motherboard of the electronic device and a corresponding opening is installed on a side of the electronic device. The I/O port switch structure comprises a base and an operation unit, wherein the base is electrically connected to the motherboard and is used for installing a plurality of I/O ports with different functions. The operation portion is connected to the base to let the base perform a rotating motion at a predetermined angle, and the user can therefore switch and use the required I/O port by operating switch elements.

Abstract: An elastic buckle utilizes the properly adjusted elastic buckle built into the T-shaped bolt to make the opening and closing of the case lid more tight to diminish the trouble of the action between the case lid and bottom case of the conventional box and case to possess highly practical effect.

Abstract: A toothbrush for false teeth includes first and second sets of bristles respectively implanted in a bottom face and a top face of a brush head, and a handle integrally formed with the brush head, the handle having a first and second recesses defined in a first side and a third recess defined in a second side face opposite the first side. The recesses arranged such that the brush can be gripped using just the index and middle fingers, and the thumb, in either of two positions, one of which is especially suitable for cleaning surfaces of the teeth, and the other of which is especially suitable for cleaning metal parts and gaps in the false teeth.

Abstract: A brush includes a handle extending from one side of the brush head. The handle includes protrusions formed on two ends of an upper surface of the handle and a concave portion formed between the protrusions of receiving the user's thumb. First and second spacers are formed on the lower side of the handle in such a manner that the first spacer is arranged to be held by the index and middle fingers of the user when the thumb is situated in the concave portion and the middle finger extends between the first and second spacers. A concave cambered surface on the second spacer can accommodate a third finger for optimal comfort and control of the handle.

Abstract: A storage box having an upper cover, a lower cover pivotally connected with the upper cover and a resilient sealing ring securely received in an edge of the lower cover so as that when the upper cover and the lower cover are engaged with each other, a water-tight engagement is achieved. Furthermore, due to an arcuate front face formed on the upper cover, the engaging force of the upper cover to the lower cover will be enhanced due to the stress-deformation effect.
