The number of fixed structures 21 is multiple and distributed in a rectangular array.

[0029] Working principle: When the feed hopper 3 needs to be replaced, the movable plate 16 is flipped first, so that the movable plate 16 and the limit block 17 are flipped with the connecting rod 15 as the central axis, and the movable plate 16 will drive the connecting rod 15 to rotate during the flipping process, so that the rotating connecting rod 15 can drive the torsion spring 19 to flip and stretch, and then the torsion spring 19 is in a flipping and pulling state. When the flipped limit block 17 is separated from the limit groove 18, the fixation of the movable block 10 and the spring 13 is released, so that the spring 13 can rebound, and the rebound spring 13 can simultaneously drive the slider 9, the movable block 10, the fixed block 11 and the limit groove 18 to move. When the moving fixed After the block 11 is disengaged from the fixed groove 12 and the movable limit groove 18 no longer corresponds to the limit block 17, the flipped movable plate 16 is loosened, so that the torsion spring 19 is no longer subjected to the tension to flip and rebound, so that the flipped rebound torsion spring 19 can drive the connecting rod 15 to rotate in the opposite direction, so that the rotating connecting rod 15 can drive the movable plate 16 and the limit block 17 to flip in the opposite direction, and then the above operation is performed again to completely disengage the fixed block 11 from the fixed groove 12, thereby releasing the fixation between the feed barrel 2 and the feed hopper 3, and then after pulling the feed hopper 3 upwards, the feed hopper 3 and the structure on the feed hopper 3 can be removed from the feed barrel 2, thereby realizing the disassembly of the feed hopper 3, and then Insert the insert block 6 on the same type of feed hopper 3 into the positioning groove 5, and then flip the movable plate 16, so that the movable plate 16 and the limit block 17 are flipped and the connecting rod 15 is driven to rotate, so that the rotating connecting rod 15 drives the torsion spring 19 to flip and stretch. When the flipped limit block 17 does not affect the connection between the fixed block 11 and the fixed groove 12, the movable block 10 is moved in the opposite direction, so that the movable block 10 can drive the fixed block 11 and the slider 9 to move, and the slider 9 will gradually squeeze the spring 13 while moving on the guide rod 8, so that the spring 13 is in a taut state. When the movable fixed block 11 is inserted into the fixed groove 12, the movable After the block 10 contacts the positioning block 4, the limit block 17 can correspond to the limit groove 18. At this time, the flipped movable plate 16 is released, and the torsion spring 19 flips and rebounds, so that the connecting rod 15 can rotate in the opposite direction, and the rotating connecting rod 15 drives the movable plate 16 and the limit block 17 to flip in the opposite direction. When the flipped limit block 17 is inserted into the limit groove 18, the restriction on the spring 13 is completed, and the spring 13 cannot rebound, thereby achieving the fixation of the position of the slider 9, the movable block 10, and the fixed block 11, and then the fixed block 11 will not be detached from the fixed groove 12, completing the fixation of the insert block 6, and realizing the connection and fixation between the feed hopper 3 and the equipment.
