Abstract:
1. A device comprising: a base having a groove; a cover having a first edge and an opposite second edge, the cover is pivotally connected with the base at the first edge thereof and having a recess at the opposite second edge thereof, the recess having a first hole formed on a bottom thereof; a first retainer disposed on the bottom of the recess; a first sliding member, adapted to be accommodated in the recess, being capable of limitedly sliding along a first axle perpendicular to the cover; a column, which is formed on the first sliding member, being capable of passing through the first hole when the first sliding member slides; a first elastomer, disposed between the cover and the first sliding member, providing a first resilient force for the first sliding member along the first axle; a second sliding member, adapted to be accommodated in the groove, being capable of limitedly sliding along a second axle perpendicular to the first axle; and a second retainer disposed at a first end of the second sliding member; a second elastomer, disposed between the base and the second sliding member, providing a second resilient force for the second sliding member along the second axle; wherein when the opposite second edge of the cover is locked to the base, the second retainer engages the first retainer of the cover by the second resilient force, when the first sliding member slides toward the base along the first axle, the column will push the second retainer to make the second sliding member to slide against the second elastomer along the second axle, so as to make the second retainer separate from the first retainer and unlock the opposite second edge of the cover from the base.
