The working principle of the carrier 100 is that the carrier 100 is in an inverted cone structure or the top is big and the bottom is small, the carrier 100 is moved to the outer side of the material box 4, the material box 4 is positioned in the notch 20 and the clamping position 10, a gap is reserved between the inner side of the clamping component 11 and the outer wall of the material box 4, the pedal component 122 of the lever component 12 is stepped on by feet, the first rotating component 121 is moved from the first moving position 30 to the second moving position 40, the clamping component 12 is lifted upwards, the inner side of the clamping component 11 is abutted with the outer wall of the material box 4 when moving upwards, and the material box 4 is lifted and separated from the ground; after the material box 4 is conveyed to the designated position, the pedal 122 is pulled upwards by hand, and the first rotating member 121 moves from the second moving position 40 to the first moving position 30, so that the clamping assembly 11 moves downwards and returns to the original position, and feeding, conveying and discharging are realized.

The above examples are also not an exhaustive list based on the utility model, and there may be a number of other embodiments not listed. Any substitutions and modifications made without departing from the spirit of the utility model are within the scope of the utility model.
