Multi-point adjustable moment limiting device and using method thereof

The invention relates to the technical field of loosening and tightening of circular matrix bolts, aims to solve the problems that in the prior art, the disassembling and assembling efficiency is low, tools are complex and diverse, the distance of an annular matrix cannot be adjusted, specific bolt torque cannot be adjusted and limited, and bolt loosening and tightening are time-consuming and labor-consuming, and provides a multi-point adjustable torque limiting device and a using method thereof. Comprising a shell; a driving gear is arranged in the shell, one side of the driving gear is connected with a plurality of driven gears in a meshed mode, and the driven gears move and are locked in the radial direction of the shell. The other end of each driven gear is connected with a sleeve. The device has the beneficial effects of being convenient to operate, high in disassembly and assembly efficiency, high in expansibility, simple in use method, labor-saving in operation by means of an electric tool or a manual
