Multi-hole drilling device

The invention discloses a multi-hole drilling device comprising a case, a control circuit, a drilling mechanism and a clamp mechanism. The clamp mechanism comprises a slide rail, a moving clamp seat and a movable fastener. The slide rail is arranged on a working platform of the case. The moving clamp seat is disposed on the slide rail in the sliding mode, and the movable fastener is disposed at the end of the slide rail and used for fastening or loosening the moving clamp seat. The drilling mechanism includes at least two drill units respectively located on the side of and above the end of theslide rail. Each drilling unit includes a rotating assembly, a moving assembly, a drill bit clamping seat and a drill bit. The moving assembly is used for driving the drill bit clamping seat to moveto enable the drill bit to move away from or toward the slide rail. The control circuit is disposed in the case and electrically connected to the moving clamp seat, the movable fastener, the rotatingassembly and the moving ass
