The invention discloses a cutting device for increasing the processing accuracy of sneaker rubber soles. The cutting device comprises a base; standing plates are arranged at the top of the base; movable plates are arranged on the standing plates and can move on the standing plates in the horizontal direction; pressing rods are arranged on the movable plates and can move on the movable plates in the vertical direction; supporting rods are also arranged on the base and can move on the base in the horizontal direction; connecting blocks are arranged at the tops of the supporting rods, movable rods are arranged on the side faces of the connecting blocks, one ends of the movable rods are connected with the connecting blocks, and fixed blocks are arranged at the other ends of the movable rods; cutting knifes are arranged on the fixed blocks and vertically connected with the fixed blocks through threads; elastic elements are also arranged on the movable rods and located between the fixed blocks and the connecting blocks. By means of the cutting device for increasing the processing accuracy of the sneaker rubber soles, it can be guaranteed that the size of cut rubber is coincident with the size of a shoe sole template, and the cutting accuracy is increased.
