The invention discloses a mechanism for continuously punching workpieces. The mechanism comprises a base (1) which is rotatably connected with a guide rod (3) through a rotating shaft (2), the guide rod (3) is slidably connected with a first linear rack (4) through a dovetail groove, and a drilling machine (6) used for punching a workpiece (5) placed on the base (1) is arranged on the first linear rack (4); a platform (7) is arranged on the base (1) and slidably connected with a slider (8) through the dovetail groove, and a connecting rod (9) is obliquely arranged on the slider (8). The mechanism is higher in punching accuracy and capable of guaranteeing included angles among multiple holes when the holes are processed at the same time.
