Power plug

The invention discloses a power plug. The power plug comprises a plug shell and plug pins. Copper pieces are arranged at one ends, in the plug shell, of the plug pins, and plug holes corresponding to the copper pieces are arranged on the other face, without plug pin, of the plug shell. Current machines, electromechanical and electric equipment products nearly work with electric energy as a raw material, and the condition that a socket power strip is insufficient can frequently occur while electric equipment continues to be increased. By means of the stacking-plugging power plug, the problem that as the electric equipment continues to be increased, the socket power strip is insufficient is fundamentally solved, and the power strip buying cost is also saved. 电源插头，包括插头壳和插脚，所述的插脚在插头壳里的端设有铜件，所述的插头壳在没有插脚的另面设有与铜件相对应的插孔。如今的机械、机电、电器类产品几乎都以电能为原料工作，在用电设备不断增加的同时常会遇到插座插排不够用的情况。可相互叠插的电源插头，从根本上解决用电设备不断增加导致插排插座不够用的问题，也节省了购买插排的成本。
