A device for coupling a lid to pot, which includes two clip plates for clipping a portion where a lid body and a pressure pot are engaged with each other, a handle body for accommodating a part of the clip plates thereinside, tension springs each being fixed to the handle body on one end thereof and to the clip plates on the other end thereof to constantly pull the clip plates to a second direction, namely, a central direction of the lid body, a grip lever being set to a first position to release the sealed lid body and pressure pot by being moved due to an external force by as far as a predetermined distance and thus pushing the clip plates to a first direction, namely, a peripheral direction of the lid body, and a push button for pushing the grip lever to a second position to seal the lid body and the pressure pot by moving the grip lever and forcing the clip plates to be moved to a second direction due to a force of the tension spring.

1. A device for coupling a lid to pot for sealing a pressure pot and a lid body having a safety valve, the device for coupling a lid to pot comprising: two clip plates for clipping a portion where the lid body and the pressure pot are engaged with each other; a handle body for accommodating a part of the clip plate thereinside; tension springs each being fixed to the handle body on one end thereof and to the clip plates on other end thereof to constantly pull the clip plates toward a second direction, in other words, a central direction of the lid body; a grip lever being fixed to a first position by being moved with a hand force by as far as a predetermined distance and pushing the clip plates to a first direction, namely, a peripheral direction of the lid body to release a sealed lid body and pressure pot; and a push button for pushing the grip lever to a second position by moving the grip lever which is placed on the first position and forcing the clip plates to be moved to a central direction of a lid due to a force of the tension springs to seal the lid body and the pressure pot. 2. The system of claim 1, wherein the handle body is removably coupled to the lid body. 3. The system of claim 2, wherein the handle body is coupled to the lid body with a screw. 4. The system of claim 1, wherein a cylindrical roller is coupled to an end part of the each clip plate, respectively, the grip lever has a handle portion and a triangular sliding plate, and an apex portion of the triangular sliding plate is inserted between the two cylindrical rollers when the grip lever is grasped with a hand to move the clip plates to the first direction. 5. The system of claim 4, wherein closure preventing grooves are respectively formed on both lower ends of the triangular sliding plate, and when the grip lever is grasped with a hand and reaches the first position, the cylindrical rollers are inserted into the closure preventing grooves not to move the grip lever even when the grip lever is released from the hand force. 6. The system of claim 1, wherein the push button includes opening preventing keys on both sides of a lower part thereof, and at least one compression spring on a central portion of the lower part thereof, each of the clip plates has an opening preventing groove `8` shape through which the opening preventing key are inserted, the opening preventing key includes a support and a key device which has a smaller diameter than that of the opening preventing groove formed in the clip plate and has a diameter larger than that of the hole formed in the handle body wherein the support is inserted, and the compression spring constantly pushes the opening preventing key to be closely attached to the opening preventing groove. 7. The system of claim 6, wherein the support is formed bolt screw on the end portion and the key device has two nuts, one having a larger diameter and the other has a smaller diameter. 8. The system of claim 6, wherein the support is formed nut screw in the end portion and the key device has a washer and a bolt which is fastening the washer to the support, the washer having a diameter lager than that of the hole formed in the handle body wherein the support is inserted, the washer having a diameter smaller than that of the opening preventing groove formed in the clip plate.
