Abstract
A transmission shaft automatic connection and disengagement device and test equipment. An input shaft drives a transmission shaft to rotate through a second connection shaft, a ratchet assembly, a first connection shaft and an output shaft so as to apply an acceleration torque, gears of the input shaft and the first connection shaft can be completely engaged and completely separated through extension and retraction of piston rods of a first group of air cylinders and a second group of air cylinders so as to achieve an effect that when a driving shaft needs to perform driving, a power system gets involved, and after driving is completed, the power system is cut off, and through the ratchet assembly, the transmission shaft can be prevented from driving a motor to work in reverse.
