When the trash can needs to be moved to the upper placement plate 4, the electric push rod 3 23 is first started, and the electric push rod 3 23 is extended. The length of the connecting plate 1 24 pulls the pull rope 1 25 to move, so that the connecting plate 2 30 pulls the pull rope 3 34 and the pull rope 2 31 to move, thereby separating the locking component 1 13 and the locking component 2 14. At this time, the upper placement plate 4 loses its restriction, and then the electric push rod 1 18 is started. The electric push rod 1 18 contracts to make the upper placement plate 4 move downward along the slide rail 2 through the slide table 1, so that the height of the upper placement plate 4 is lowered to the required height. Then the staff puts the trash can on the surface of the upper placement plate 4, and the electric push rod 1 18 extends to make the upper placement plate 4 move upward and reset. Then the electric push rod 3 23 contracts to make the locking component 1 13 and the locking component 2 14 re-fix the position of the upper placement plate 4. A plurality of through holes are provided inside the upper placement plate 4 and the lower placement plate 5. 9, and the through holes 9 are evenly distributed, the bottom of the upper placement plate 4 and the bottom of the lower placement plate 5 are both fixed with electric push rods 19 by bolts, the extended end of the electric push rods 19 is fixed with a moving frame 20 by bolts, and the top of the moving frame 20 is fixed with a support column 22 by bolts, and the top of the support column 22 is rotatably connected with a ball 21, and the ball 21 can pass through the through hole 9, start the electric push rod 19, the electric push rod 19 contracts to make the moving frame 20 drive the support column 22 to move upward, and then make the ball 21 pass through the through hole 9, and make the ball 21 slightly protrude from the surface of the upper placement plate 4, so that the ball 21 contacts with the bottom of the trash can, the staff pushes the trash can on the upper placement plate 4, and the ball 21 rotates, so that the staff can move the trash can more labor-saving and smooth,Similarly, the trash can on the lower placement plate 5 can be moved.
