When a bottle is stuck, the inclined surface in the transmission groove presses the transmission block, so that the transmission block squeezes the pressure spring and moves toward the inside of the transmission ring along the disengagement groove. When the transmission block is completely out of the transmission groove, the locking rod on the output end of the locking cylinder pushes outward to limit the locking slider on one side of the transmission block to prevent the transmission block from moving outward again. At this time, the connecting ring and the transmission ring rotate relative to each other. When the rotation of the mechanism is blocked, the transmission connection of the equipment is quickly cut off, eliminating safety hazards; the mounting table is rotationally supported by the support shaft rotatably connected to the puller block, and the reset spring in the puller block elastically supports the push rod, and the limiter on the mounting table is pressed against the puller block, forming a flexible connection structure of the puller card plate, which avoids bumps at the contact position of the bottle and causes product loss. At the same time, when the bottle is stuck, it is convenient to take out the bottle, shortening the time for troubleshooting. BRIEF DESCRIPTION OF THE DRAWINGS
