[0043] In order to conveniently collect the debris generated during the processing of the PCD saw blade 5, in some embodiments, the PCD saw blade 5 clamping structure further includes a debris collection box 61, which is fixed to the bracket 1 and is arranged below the first clamping assembly 3 and the second clamping assembly 4.
