Clamping forceps special for quartz filter membrane of atmosphere PM2.5 particle sampler

The invention discloses a pair of clamping forceps special for a quartz filter membrane of an atmosphere PM2.5 particle sampler. The pair of clamping forceps comprises an upper forceps piece, a lower forceps piece, an upper forceps handle and a lower forceps handle. The rear end of the upper forceps handle is elastically connected with the rear end of the lower forceps handle. The upper forceps piece is installed at the front end of the upper forceps handle. The lower forceps piece is installed at the front end of the lower forceps handle. A clamping gap is formed between the upper forceps piece and the lower forceps piece. The upper forceps piece comprises a first arc-shaped piece and a second arc-shaped piece. One end of the first arc-shaped piece and one end of the second arc-shaped piece are both hinged to the upper forceps handle. The lower forceps piece comprises a third arc-shaped piece and a fourth arc-shaped piece. One end of the third arc-shaped piece and one end of the fourth arc-shaped piece are both hinged to the lower forceps handle. When the quartz filter membrane is clamped by the forceps, the forceps pieces only act on the edge of the quartz filter membrane, samples at the central area of the quartz filter membrane can not be polluted, and the angles of the forceps pieces on the forceps handles can be adjusted so that the forceps can adapt to quartz filter membranes of different sizes.
