Claim 2:
3. The door lock with energy saving device as claimed in claim 1, including a second type flexible body, the second type flexible body has a ring seat, the center of the ring seat has an axial column which is dangly, and the conductive sheet assembly which arranged at the bottom of the axial column and the ring seat is composed of a first conductive sheet, and the upper end of the second type flexible body is provided with a first pushing surface located at the top of the axial column; the compression spring assembly is composed of a first compression spring, its one end is against the outer periphery of the flange of the mandrel, and the other end is against the first pushing surface; when the mandrel is sliding inward in the through hole, urging the flange to compress the first compression spring to force the second type flexible body to move toward the direction of button circuit board, so as to make the first conductive sheet contact the first contact of the button circuit board to form a close loop; and when the mandrel is sliding outward in the through hole, the first compression spring rebound to force the second type flexible body to move away from the direction of button circuit board, so as to make the first conductive sheet separate from the contact between the first contact of the button circuit board to form an open loop.
