• and
• a core recess defined in a distal end of an X-axis of the deadbolt recess and communicating with the installation recess,
• wherein the deadbolt recess includes a first guiding slot defined in a wall thereof,
• wherein the core recess includes:
• a second guiding slot defined in a wall thereof,
• a third positioning wall on a top thereof, the third positioning wall including the first positioning portion located at a top thereof and a second positioning portion formed on a bottom thereof,
• a fourth positioning wall which is located corresponding to one end of the third positioning wall,
• an elongate groove defined in one end of the fourth positioning wall, and
• a core hole defined through an inner bottom and located along a Z-axis thereof,
• wherein the latch bolt recess includes a latch bolt which includes a head, a passive member and a spring, the passive member being fixed to the head, and the spring biasing the passive member,
• wherein, when in a closed position, the spring extends to protrude the head out from the case, and when in an opened position, the spring is compressed so that the head does not protrude out from the case,
• wherein the installation recess includes a top rotation member and a bottom rotation member, the top rotation member and the bottom rotation member overlapping with each other without driving each other,
• wherein the top rotation member includes a first transmission member, a first hole located corresponding to the installation hole, and a first contact portion,
• wherein the bottom rotation member includes a second transmission member, a second hole which is located corresponding to the installation hole, and a second contact portion,
• wherein the first positioning portion includes a first resilient member which biases the first contact portion and the second contact portion,
• wherein, when the first transmission member is rotated, the first contact portion compresses the first resilient member and pushes the passive member so that the spring is compressed and the head does not protrude out from the case,
• wherein, when the second transmission member is rotated, the second contact portion compresses the first resilient member and pushes the passive member so that the spring is compressed and the head does not protrude out from the case, and
• wherein, when in the closed position, the first resilient member bounces back and contacts the first contact portion and the second contact portion, and the first transmission member and the second transmission plate do not contact the passive member.

A lock comprising a case, the case including:

• a first part and a second part which is connected to the first part to form the case;

• an elongate groove defined in one end of the fourth positioning wall, and
• a core hole defined through an inner bottom and located along a Z-axis thereof;
• wherein the core recess has a first guide member, a restriction plate, a driving member, an extension plate, and a stop plate received therein, the core recess defining a loop-like rail;
• wherein a bottom of the restriction plate is located at the rail;
• wherein the first guide member extends through a first guide hole defined in the restriction plate;
• wherein a resilient unit is biased between the restriction plate and a bottom of the third positioning wall;
• wherein the resilient unit is connected to the second positioning portion and a resilient direction of the resilient unit is correspondent to the first guide hole;
• wherein the restriction plate includes at least one engaging member;
• wherein one end of the driving member is connected to a deadbolt which is movable in the deadbolt recess and is stopped by the stop wall, the driving member including:
• a slide slot in which the first guide member extends,
• a second guide member which is slidable in the first guiding slot and located opposite to one end face of the restriction plate,
• a first notch and a second notch defined in a top thereof,
• a third guide member located opposite to a bottom of the deadbolt, corresponding to the second guiding slot, and opposite to one end face of the restriction plate;
• wherein the extension plate has an end thereof eccentrically and pivotably connected to the second guide member, the extension plate including:
