Coupler quick connection system capable of automatically matching height of driving shaft

The utility model belongs to the technical field of machinery, and relates to a quick coupling connection system capable of automatically matching the height of a driving shaft, which comprises a base, a movable sliding table slidably connected to the upper end of the outer surface of the base, a frame fixedly connected to the upper end of the movable sliding table, and shells slidably connected to two sides of the inner surface of the frame. One side of the inner cavity of the shell is movably connected with a male end driving shaft, and one side of the outer surface of the base is provided with a driven shaft. By means of the arrangement, movement of the movable sliding table can be more stable and accurate, the movable sliding table enables the male end driving shaft to move forwards to be meshed with the driven shaft, meanwhile, the sheet motor rotates at a low speed, the male end driving shaft and the driven shaft can be buckled, and therefore the driven shaft is driven to rotate, manual operation is not
