Clamping device of planer type milling machine

The utility model discloses a planer type milling machine clamping device which comprises a milling machine, a first threaded hole is formed in the upper end face of the milling machine, a first threaded rod is in threaded connection with the interior of the first threaded hole, the first threaded rod penetrates through the upper end face of a supporting plate and is fixedly connected with a first rotary knob, and a second threaded hole is formed in the supporting plate. The upper end face of the milling machine is fixedly connected with a connecting plate. When a worker places a workpiece downwards through a V-shaped plate, the workpiece can be limited, it is guaranteed that the workpiece is more stable during placement, meanwhile, when a threaded sleeve supports a second threaded rod, the second threaded rod controls a clamp to abut into the workpiece, the stability of the workpiece is improved, the workpiece is prevented from deviating during tapping, and the working efficiency is improved.
