The invention discloses a simple casting material handle thickness gauge which comprises a base, an adjustment detection device, a lifting adjustment device and a clamping device; the adjustment detection device comprises a groove, a hydraulic rod, a movable plate, a supporting rod, a detection plate, a first detection groove and a second detection groove, the groove is formed in the base, and thehydraulic rod is mounted in the groove; the output end of the hydraulic rod is fixedly connected with one side wall of the movable plate; the lifting adjustment device comprises a control box, a servo motor, a transmission rod, an inner groove, a first gear, a second gear, a supporting plate, a guide groove, a screw and a movable block, the control box is mounted on the side wall of one end of the base, the servo motor is mounted in the control box, and the supporting plate is fixedly connected to one side of the top end of the base. The hydraulic rod continues to drive the movable plate to move, the movable plate drives the detection plate to move along a material handle through the supporting rod, and when the thickness of the material handle is larger than that of the first detection groove and the second detection groove, disqualification is achieved, and rapid detection is facilitated.
