Claim 1:
2. The door lock with energy saving device as claimed in claim 1, including a first type flexible body, the first 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 a second conductive sheet annularly arranged on the outer periphery of the first conductive sheet, and the upper end of the first type flexible body is provided with a first pushing surface and a second pushing surface which are respectively located at the top of the axial column and the ring seat; the compression spring assembly is composed of a first compression spring and a second compression spring annularly arranged on the outer periphery of the 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 and the second pushing surface; when the mandrel is sliding inward in the through hole, urging the flange to compress the first compression spring and second compression spring to force the ring seat and the axial column of the first type flexible body to move inwards, so as to make the second conductive sheet and the first conductive sheet successively contact the second contact and the first contact on the upper edge of the button circuit board; and when the mandrel is sliding outward in the through bole, make the flange to against the top end of a second through hole, and the first compression spring and second compression spring rebound to force the axial column of the first type flexible body to move outwards, so as to make the first conductive sheet firstly separate from the contact between the first contact of the button circuit board to form an open loop.
