A combining protrusion is formed in a main shaft(30) of the model lens fixing unit to remove a supporter(4) having a combining groove. A supporting unit(60) is formed in an operating shaft(6) and another operating shaft(8) is formed in the supporting unit with a pressurizing device. A handle(80) is attached on the outside of the operating shaft and a combining protrusion(81) is attached on the inside of the operating shaft to removably combine a model lens compressing plate(9). A model lens(10) is inserted between the model lens compressing plate and the supporter and thus, the cutting unit cuts a lens in the same shape as the model lens.
