The first paddle 48 and the second paddle 50 are used to push the shredded material that falls into the second collection chamber 46 into the interior of the second collection chamber 46, and then transfer it into the first collection chamber 13 for centralized collection. The first strip hole 56 is used to prevent the shredded material from getting tangled on the second paddle 50 and to intercept the shredded material in the second collection chamber 46. The second strip hole 57 is used to prevent the shredded material from getting tangled on the first paddle 48 and to intercept the shredded material in the second collection chamber 46. Both the first paddle 48 and the second paddle 50 are made of elastic alloy material and have deformation function, which can effectively remove the shredded material.
