摘要:
A locking device for locking a first component to a second component comprises a fastener and a head. The fastener has an elongated main body, and the head is connected to one end of the main body. The main body inserts into the first component to lock with the second component. The head resists the first component, the head includes a resistance surface facing the main body and at least one restriction structure defined on the resistance surface of the head. The at least one restriction structure engages with the first component, such that the fasteners can be arranged on the first component in a predetermined manner. An electronic apparatus using the locking device is also provided.

A card assembly is used for enabling a first electronic device to be compatible with a card used in a second electronic device. The card assembly defines a first group of specification parameters of the first electronic device to be detachable received in the first electronic device, and further defines a second group of specification parameters of the card. The second group of specification parameters allows the card to be detachable received in the card assembly. When the card assembly, with the card, is received in the first electronic device, the card is directly and electrically connected to the first electronic device.

The present invention relates to a musical pillow. The music pillow includes a body, a pillow core defining a first receiving cavity corresponding to a users' head, and a music player device. The body includes a first base, and two sidewalls extending from two opposite sides of the first base. Two free ends of the two sidewalls face each other to define a body opening therebetween. The first base and the two sidewalls cooperatively define a receiving space. The pillow core is received in the receiving space, while the first receiving cavity is communicated with the body opening. The music player device includes two speakers positioned on the sidewalls respectively and a playing unit positioned in the first base. The speakers are electrically connected to the playing unit.

A depth checking device includes a body member, a pressing member, a checking member and an adjustment nut. The body member defines a stepped through hole forming a stopping surface inside. The pressing member includes a first end and an opposite second end. The first end includes a first end surface defining a first opening. The second end defines a second opening. The checking member is mounted in the stepped through hole and includes an indication end adjacent to the first end and a probe end. The indication end includes a second end surface. The adjustment nut is screwed on the checking member and supported by the stopping surface in a position where the first end surface is coplanar with the second end surface and the probe end protrudes from the body member with a protruding length of the probe end same as a designed depth of a fixing hole.

An automatic installation device for automatic procuring and fixing an object to a product is mounted on a base. The automatic installation device comprises an elevating mechanism, a loading mechanism for procuring the object, and a flexing mechanism connected between the elevating mechanism and the loading mechanism. The flexing mechanism is capable of driving the loading mechanism moving between the object and the product for aligning the object with the product in a first orientation. The elevating mechanism is capable of driving the loading mechanism to move in a second orientation perpendicular to the first orientation to drive the loading mechanism moving adjacent to the product and fixing the object to the product.

A positioning device includes an antenna, a receiving module, a processing module and an output module. The receiving module receives positioning signals transmitted from positioning satellites and a position signal of another positioning device transmitted from a ground monitoring system using the antenna. The processing module determines a position of the positioning device according to the positioning signals, and calculates a distance between the positioning device and another positioning device according to the position signal of the position device and the position signal of the another positioning device. The output module outputs the distance. A method for measuring the distance between the positioning devices is also provided.
