[0032] When the power adapter body 1 needs to be used, the metal pin 3 on the power adapter body 1 is inserted into the socket, then the elastic ring 62 at the end of the limiting column 61 contacts the wall surface, the center screw 8 is rotated, the adjusting frame 7 connected by threads is moved after the center screw 8 is rotated, the piston rod 63 is synchronously moved in the limiting column 61 after the adjusting frame 7 is moved, the negative pressure is generated in the limiting column 61 through the movement of the piston rod 63, and then the limiting column 61 is stably adsorbed on the wall surface, so as to guarantee the stability of the power adapter body 1 inserted into the socket.

[0033] The technical content disclosed in the embodiment is further improved on the basis of the above-mentioned embodiment one. The existing power adapter is convenient for heat dissipation when in use by arranging the heat dissipation openings 4 thereon. However, the heat dissipation openings 4 are always in an exposed state, and when the adapter is idle and stored, dust in the external environment is likely to enter the internal part of the adapter through the heat dissipation openings 4. The heat dissipation openings 4 are arranged on the side of the power adapter body 1, and the dustproof nets 5 are fixedly installed in the heat dissipation openings 4.
