The invention discloses an intelligent equipment and a band body dismounting device thereof. The band body dismounting device comprises triggering pieces, a reset piece, a shell, connecting pieces anda transmission block. The triggering pieces and the connecting pieces are in cooperative transmission with a wedge-shaped part of the transmission block. When moving towards the interior of the shellin the first direction, the triggering pieces can drive the transmission block to move in the second direction, and the transmission block can drive the connecting pieces to move towards the interiorof the shell in the first direction, the reset piece can drive the transmission block to reset in the second direction, so that the transmission block can drive the triggering pieces and the connecting pieces to reset towards the exterior of the shell in the first direction. According to the band body dismounting device, dismounting connection between an electronic equipment body and a band bodycan be achieved, maintaining and using of the electronic equipment body are facilitated, meanwhile, by means of transmission of the wedge-shaped part, relative movement of the transmission block, thetriggering pieces and the connecting pieces can convert between the two directions, and the band body dismounting device is compact in structure.
