The invention relates to a food processing device, comprising a substrate with a first pivot and a second pivot, a food processing component arranged on the substrate, and a pressing arm which is connected with the substrate in a pivoted manner. The pressing arm comprises a first pressing arm part and a second pressing arm part which are connected with each other through a pivot. The two pressing arm parts are respectively connected with a pivot of the substrate. Thus, the first pressing arm part and the second pressing arm part form a combined lever mechanism. Force applied on the second pressing arm part by a user is increased when being output from the second pressing arm part. The increased output force is applied on the first pressing arm part, so that labor and time are saved in operation, and the device is very convenient to use.
