10. A method of using an AGV intelligent handling robot as described in any one of claims 1-9, characterized in that: The specific steps of the structure include the following: S1: Rotate the top plate (106) to one side by using the handle, place the goods to be transported on the placement plate (102), and rotate the top plate (106) again by using the handle so that the top plate (106) is directly above the goods. S2: Rotate the screw (112), and the screw (112) drives the round rod (114) and the top plate (106) to move downward through the threaded sleeve (113). The top plate (106) rests against the top of the goods, which can move and fix the goods from above, and at the same time can protect the goods from rain on rainy days. S3: Start the servo motor (111a). The output end of the servo motor (111a) drives the bidirectional threaded rod (111b) to rotate. The bidirectional threaded rod (111b) moves relative to each other through two moving sleeves (111c) and two connecting rods (111d), which in turn drives the two L-shaped moving plates (111e) and two clamping plates (111f) to move relative to each other. The two clamping plates (111f) press against the goods to fix them in place. S4: When a program error or signal interruption occurs during the operation, causing the transport robot to deviate from the preset track and collide with other transport robots or buildings, the buffer plate (201) is subjected to the frontal impact force, and the buffer plate (201) buffers the impact force through the buffer spring (202). S5: Simultaneously, the buffer plate (201) pushes the moving rod (204) through the connecting assembly (205) and the mounting plate (203). The moving rod (204) abuts against the first inclined block (312a) and pushes the first inclined block (312a). The first inclined block (312a) presses down on the second inclined block (312b), causing the first inclined block (312a) to move downward. The first inclined block (312a) pushes the toothed plate (301) through the pushing rod (312c) and the push plate (312d). The toothed plate (301) drives the two second gears (303) to rotate through the two first gears (302). The two second gears (303) drive the first threaded rod (304) and the second threaded rod (305) to rotate respectively. This causes the first rectangular rod (306), the second rectangular rod (307), the first sealing slide plate (308), and the second sealing slide plate (309) to move upward, so that the gas at the upper end of the rectangular cavity is squeezed into the lower pressure plate (107) through the first hose (310). The gas in the second cavity (109) is sucked into the lower end of the rectangular cavity through the second sealing slide plate (309). Then the lower pressure plate (107) moves downward and presses on the goods to further compress the goods. The gas in the second cavity (109) decreases and sucks the goods through the connecting port (110), so that the goods can be firmly fixed on the placement plate (102) by the impact force of the handling robot, preventing the goods from falling off the placement plate (102). S6: When the second inclined block (312b) moves downward, it drives the moving pressure plate (313c) to move downward through the pressure rod (313a). The moving pressure plate (313c) squeezes the gas in the connecting box (313b) into the circular cavity (313f) through the connecting pipe (313e), so that part of the brake block (313g) is squeezed out of the connecting port and contacts the ground, which in turn increases the friction between the brake wheel (313d) and the ground, accelerates the braking of the handling robot, and thus protects the handling robot itself and the goods.
