A lock device for detachably mounting a cover on a base, a recess being formed on the cover, a first hole being formed on the bottom of the recess, a first retainer being extended out of the bottom of the recess, a groove being formed on the base, the lock device comprising:

• a first sliding member, adapted to be accommodated in the recess, being capable of limitedly sliding along a first axle relative to the cover, a column which is capable of passing through the first hole being formed on the first sliding member;
• a first elastomer, disposed between the cover and the first sliding member along the first axle, for supporting the first sliding member;
• and
• a second sliding member, adapted to be accommodated in the groove, being capable of limitedly sliding along a second axle relative to the base, a second retainer which is used for the first retainer to lock being formed on the second sliding member;
• wherein 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 along the second axle, so as to make the second retainer separate from the first retainer.
