Claw type cutter, shredder comprising same and combination device

The invention relates to a claw type cutter. A cutter rest comprises a fixing part and a cutting supporting part, wherein one end of the cutting supporting part is connected with one end of the fixing part to form a triangular plane; a cutter body comprises a cutter holder, a first cutting part and a second cutting part; the first cutting part and the second cutting part are arranged on the cutter holder in parallel, and a cutting gap is left between the first cutting part and the second cutting part; and at least one cutting part is a cone and is provided with an inwards-concave arc-shaped front cutting surface. According to the claw type cutter, all power is applied to shredding of materials such as a plastic film, the claw type cutter is used for overcoming the disadvantages that the material cannot be fully cut due to expanded gap between a moving cutter and a fixed cutter or abrasion of a cutting angle in the prior art and the defects of high electrical consumption, frequency in cutter replacement, high blocking fault rate, high using cost and the like; and the claw type cutter is applied to various shredding equipment or forms the combination device together with other equipment, and the overall efficiency is improved remarkably.
