b. the rotating rod (10) rotates and drives the belt pulley 16 connected with the rotating rod to rotate, the belt pulley 16 drives the other belt pulley (16) to rotate through the conveying belt (14), the belt pulley 16 drives the threaded rod 13 to rotate, the fixed seat (7) moves downwards, the fixed seat (7) drives the anti-slip pad (6) to move downwards, the lower end of the anti-slip pad contacts with the ground in a grounding manner, only the roller is prevented from being grounded, and the stability of the cart main body (1) during carrying goods is improved;

c. then, after the goods are carried, the rotating ring (18) is reversed according to the steps, the rotating ring (18) drives the rotating rod (10) to rotate, the rotating rod (10) drives the winding shafts to rotate, the winding shafts store the first connecting ropes (9), the second connecting ropes (11) are loosened at the same time, the plurality of railings (2) are unfolded, and the sleeves (19) are unfolded at the same time;

d. the rotating rod (10) rotates and drives a belt pulley (16) connected with the rotating rod to rotate, the belt pulley (16) drives the other belt pulley (16) to rotate through a conveying belt (14), the belt pulley (16) drives a threaded rod (13) to rotate, so that the fixing seat (7) moves upwards, and the fixing seat (7) drives the anti-slip pad (6) to move upwards, so that the lower end of the anti-slip pad is separated from the ground; the cooperation of the pulley (16) with the conveyor belt (14) is known to those skilled in the art and will not be described in detail herein;

e. then, the two rotating plates (3) can be rotated to be in an inclined state, then, the rotating handle (28) is pushed to push the sliding rod (24) to move, the sliding rod (24) pushes the extruding plate (25) to prop against the goods, and then the first bolt (27) is rotated to be connected with the threaded hole (26) so as to limit the extruding plate (25), and in the goods carrying process, if the goods meet an ascending place, the goods can be prevented from falling through the arrangement of the structure;

f. then, the second bolts (29) are rotated to enable the connecting plates (30) at two sides to be extruded and fixed with the goods, and before the connecting plates (30) are propped against the goods, the connecting plates (30) are rotated to be in an inclined state, so that the connecting plates (30) can be used for better fixing a plurality of the goods; if the goods are higher, the T-shaped rods (31) can be pulled out through the pull rings (32), and the higher goods can be fixed through extrusion of the T-shaped rods (31) at the two sides;

g. if the goods are higher, the sliding blocks (20) are pushed to move upwards, the sliding blocks (20) can move upwards through the sleeves (19), the sliding blocks (20) move upwards to push the push rod (21), the push rod (21) pushes out the extension rod (37) through the extension block (34), so that the height of the railing (2) is adjustable, and when the goods piled on the trolley main body (1) are higher, the trolley can be protected;

h. in the upward moving process of the sleeve (19), the arc-shaped block (33) can be extruded to slide into the mounting groove (41), the spring (40) is extruded, after the sleeve (19) slides over the arc-shaped block (33), the outer end of the arc-shaped block (33) slides out of the mounting groove (41) due to the action of the spring (40), and the sleeve (19) is limited.
