The invention relates to the technical field of pneumatic tools, in particular to a pair of pneumatic
cutting pliers. The pair of pneumatic
cutting pliers comprises a cylinder
barrel, an end cover sealing ring, a
piston, a
piston rod, a scissor head top piece, a scissor head mounting support, a scissor head and an end cover body, wherein the cylinder
barrel is of a
barrel-shaped structure, one end of the cylinder barrel is connected with the end cover body, an air valve, an exhaust silencer, a control
handle and an air inlet are arranged on the end cover body, a hanging piece is arranged in the control
handle, the
piston is arranged in the cylinder barrel, the piston sealing ring is arranged on the piston, the
piston rod is installed on the piston, the cone-shaped scissor head top piece is arranged at the top end of the
piston rod, a piston spring is connected on the
piston rod in a sleeved mode, the other end of the cylinder barrel is connected to the scissor head mounting support, and the scissor head is installed on the scissor head mounting support. The pair of pneumatic
cutting pliers is simple and scientific in structural design, free of air leakage in use, small in
noise and stable in using performance and working performance.
