This invention relates to a fixing piece for fixing a radiator on a CB including several fixing pieces, every one of which includes a sleeve, a screw and an elastic element changing the shape along the radial direction of the sleeve, in which, one end of the sleeve forms a head, the other end is set with an elastic piece changing shape along the radial direction and having an agnail structure, said elastic element is set outside of the sleeve and placed between the head and the agnail structure, one end of said screw is fixed in the sleeve,the other end includes a screw section popping out of the sleeve, which can either cover the spring on the fixing piece or assemble the fixing piece to the radiator in advance conveniently.

The invention relates to a heat dissipating device which is used for dissipating heat of an electronic element on a circuit board and comprises a radiator and a plurality of fixing pieces fixing the radiator on the electronic element, the radiator comprises a bottom plate and a radiating fin set attached on the bottom plate; each fixing piece comprises a sleeve, a rod piece penetrated into the sleeve and a spring sleeved on the rod piece, wherein the rod piece comprises a head part, a rod body extending from the head part and a threaded section formed at the tail end of the rod body, the sleeve comprises a cylinder body positioned on the bottom plate and a combination cylinder formed at the bottom of the cylinder body, the combination cylinder is penetrated into the bottom plate and is fixed and clamped with the bottom plate, the rod body is penetrated into the combination cylinder, and the threaded section is clamped under the combination cylinder. Being provided with the sleeve and the combination cylinder, the fixing piece can be conveniently connected with the rod piece and the spring and can also be convenient for being clamped on the bottom plate of the radiator for fixing, the heat dissipating device is not prone to the hidden trouble of leading the springs, the rod pieces and the sleeves to be fallen because of inadvertency during the installation.

The invention discloses a leftward and rightward door opening mechanism and a refrigerator. The leftward and rightward door opening mechanism comprises a hinge module arranged on a refrigerator door body and a driving module arranged on a refrigerator box body, wherein the driving module comprises a driving bottom plate, two first gears oppositely arranged on the driving bottom plate, a driving rack driven through the first gears and second gears separately driven by the first gears, and the driving rack is guided and limited by the second gears; the hinge module comprises a hinge bottom plate and two hinges oppositely arranged on the hinge bottom plate, and the hinges drive the first gears; when the two hinges are both meshed with the first gears, the door body is locked; and when the hinge on one side is separated from the first gear but the hinge on the other side is still meshed with the first gear, the door body is open. As rotating shafts are arranged on the door body, the door can be opened from the left side as well as the right side without making any adjustment.

The invention discloses a left and right door opening mechanism and a refrigerator. The left and right door opening mechanism comprises a hinge module and a transmission module which are arranged on a refrigerator body and a refrigerator door body correspondingly. The hinge module comprises a hinge bottom plate and arc-shaped bosses located on the two sides of the hinge bottom plate, wherein the hinge bottom plate and the arc-shaped bosses are provided with open grooves toward the direction of the refrigerator door body. The transmission module comprises a transmission bottom plate and a plurality of shafts fixedly arranged on the transmission bottom plate. Each shaft comprises a first shaft body and a second shaft body, wherein the first shaft body is located in the corresponding open groove so as to achieve rotation of the door body, and the second shaft body is located outside the corresponding open groove so as to limit the corresponding arc-shaped boss. When the first shaft bodies and the second shaft bodies on one side of the transmission module leave the inner sides and the outer sides of the arc-shaped bosses, the first shaft bodies and the second shaft bodies on the other side of the transmission module are located on the inner sides and the outer sides of the arc-shaped bosses correspondingly, and the door body is opened. According to the left and right door opening mechanism and the refrigerator, the hinge module and the transmission module are provided with the arc-shaped bosses and the multiple shaft bodies correspondingly, and thus left side door opening and right side door opening can be achieved simultaneously under the circumstance without any adjustment.
