The invention discloses a track type slidable socket. The track type slidable socket includes a socket attaching track, a power supply wire, a socket shell, socket holes and a plug, wherein the socket attaching track is installed on an indoor or outdoor building wall, the power supply wire is installed in the socket attaching track, the socket holes are installed at the front surface of the socket shell, and the plug is installed on the back surface of the socket shell. The track type slidable socket of the invention is provided with the socket holes in different standards and the unified plug, and therefore, with the track type slidable socket adopted, electric appliance power utilization requirements of tourists or students who come to China from countries in which sockets in other standards are used or tourists or students from countries in which sockets in national standards are used, can be satisfied; a plurality of sockets can be additionally adopted, so that inconvenient charging which is caused by insufficient sockets in many occasions can be eliminated; and the socket of the invention can linearly slide on the track, and therefore, the problem of incapability of realizing charging which is caused by a situation in which the socket is too far away from a target charging electric appliance and a wire is too short can be solved.

The invention discloses a plastic trash can which comprises a pedestal, wherein a first trash can body and a second trash can body are mounted on the left and right sides of the upper end of the pedestal; a middle shaft plate is mounted between the first trash can body and the second trash can body; a spring is mounted at the bottom end of an inner cavity of the middle shaft plate; the upper end of the spring is fixedly connected with an extraction plate; the extraction plate is T-shaped; the upper end of the extraction plate is fixedly connected with a can cover; clamping slots are formed in the left and right sides of the lower end of the can cover; the clamping slots are located right above the first trash can body and the second trash can body; and bulges matched with grooves and arc-shaped blocks are reserved at two ends of the clamping slots. The plastic trash firstly solves the problem that the space is not enough, and then clamps hinged with plastic bags are clamped into the grooves to control the plastic bags, so that the plastic bags cannot easily slide off when blown by wind; after the can cover is closed, a user can directly hold the can cover without feeling sick; and therefore, the plastic trash can is a novel product very worthy of being popularized.

The invention discloses a method for releasing a port of carrier-grade network address translation equipment. According to the method, a carrier-grade network address translation device is involved; the carrier-grade network address translation device comprises a network address translation module, a port release module, a user address mapping table, a local translation mapping table, an idle port list and a local session mapping table; the carrier-grade network address translation device releases the port according to the occupation situation of the port accessed by a user; and the carrier-grade network address translation device executes the following steps on an arrived message: (a) inquiring the local translation mapping table; (b) inquiring the user address mapping table; (c) releasing the port; and (d) processing the local session mapping table.
