Explosion-proof piece clamp convenient to disassemble

The utility model relates to the technical field of disassembly and assembly of anti-explosion sheets, in particular to an anti-explosion sheet clamp convenient to disassemble, which comprises an upper annular plate and a lower annular cylinder, a lower backing ring detachably abuts against the inner part of the lower annular cylinder, and a plurality of vertical grooves are formed in the part, above the lower backing ring, of the inner peripheral side wall of the lower annular cylinder. Transverse grooves are formed in the positions, matched with the vertical grooves, of the top face of the lower backing ring, an annular clamping plate detachably abuts against the bottom face of the upper annular plate, a plurality of L-shaped containing frames are connected to the bottom face of the annular clamping plate, and an anti-explosion piece body detachably abuts against the short supporting top faces of the L-shaped containing frames. An upper backing ring which can abut against the top face of the anti-explosion
