Active disassembly structure of tablet personal computer

The invention discloses an active disassembly structure of a tablet personal computer. A plastic buckle and a shape memory alloy round tube are combined in the tablet personal computer to manufacturea connecting piece between shells, screws made of shape memory polymer materials are used for fixing all internal components, and meanwhile an electric heating wire connected to a metal shell of the tablet personal computer is used for providing the required temperature for exciting the shape memory materials. The waste tablet personal computer is conveyed to the disassembling unit through the conveying unit, a control piece in the disassembling unit drives the multiple pairs of electrifying contacts to move up and down in a reciprocating mode, the contacts make full contact with a metal shellof the tablet personal computer when moving downwards, and the electric heating wires are electrified to emit heat, so that the two shape memory materials are heated and excited, and all connection relations lose efficacy.
