The working principle of the limiting device is as follows:

when the limiting block 19 is at a low point, the limiting block 19 is trampled to push the push rod 38 to move downwards and compress the second spring 40, then the rotating rod 39 is driven to rotate by rotating the lifting device, so that the locking piece 45 is driven to rotate, the locking piece 45 is parallel to the locking hole 46, meanwhile, the push rod 38 moves upwards under the action force of the second spring 40 to drive the rotating rod 39 to move upwards, and at the moment, the locking piece 45 penetrates upwards from the locking hole 46 to complete the lifting of the limiting block 19;

when the limiting block 19 is at a high point, the limiting block 19 is trampled to push the push rod 38 to move downwards and compress the second spring 40, then the rotating rod 39 is driven by the rotary lifting device to move downwards and rotate, so that the locking piece 45 is driven to pass through the locking hole 46 downwards and rotate, the locking piece 45 is perpendicular to the locking hole 46, meanwhile, the push rod 38 moves upwards under the action force of the second spring 40 to drive the rotating rod 39 to move upwards, and at the moment, the locking piece 45 is clamped on the second bottom plate 41 and does not move upwards any more, so that the limiting block 19 is lowered;
