The working principle of the invention is as follows:

as shown in figure 1, in the initial state, the roller 8 inclines towards the left, the motor 9 drives the round roller 5 to rotate through the output shaft, when the round roller 5 rotates, the roller 8 clings to the round roller 5, so the round roller 5 can drive the roller 8 to rotate synchronously, because the roller 8 is arranged on the connecting seat 6 in an inclined shape, when the roller 8 rotates, the round roller 5 provides a component force in the horizontal direction, and the direction of the component force is the same as the inclined direction of the roller 8, so that the roller 8 can move along the round roller 5 from side to side along the rotation of the round roller 5, so the movement of the roller 8 can drive the sliding seat 11 to slide from side to side on the sliding plate 3, because two reversing seats 10 are arranged, when the sliding seat 11 slides to the leftmost end, the pushing column 46 on the reversing seat 10 can push the first deflector rod 22 to rotate from right until being limited by the small round rod 17 and can not rotate continuously, when the rightmost end of the first deflector rod 22 rotates, can rotate the right-hand member simultaneously through spring 23 pulling second driving lever 25 and be blocked by small circle pole 17, the first driving lever 22 of pulling force through spring 23 and second driving lever 25 can tightly support on small circle pole 17, can drive bull stick 7 to rotate simultaneously in the rotation of second driving lever 25, bull stick 7 can drive gyro wheel 8 and rotate simultaneously, thereby gyro wheel 8 can follow and incline to turn to the right side towards left side slope, thereby round roller 5 begins to drive gyro wheel 8 pivoted and begins to move towards the right side simultaneously, along with the rotation of round roller 5, two switching-over seats 10 of cooperation can realize the reciprocal side-to-side motion of slide 11 on the goods shelves. Thereby realizing the function of the screen 16 moving back and forth left and right on the link frame 2.

The working of the rotating module, when the sliding base 11 moves left and right along with the roller 8, the sliding base 11 can push the screw 20 to move simultaneously, because one end of the screw 20 far away from the sliding base 11 is connected to the power base 19 in a sliding manner, the power base 19 is provided with the clamping column 28, when the screw 20 slides on the power base 19, because the clamping column 28 is clamped in the thread of the screw 20, the sliding base 11 pushes the screw 20 to move, the screw 20 is pushed to rotate simultaneously, the rotation of the screw 20 can drive the rotating shaft 34 to rotate simultaneously through the transmission of the bevel gear 33, the rotating shaft 34 can drive the circular sleeve 14 to rotate, the circular sleeve 14 can drive the rotating drum 37 to move, the rotation of the rotating drum 37 can drive the screen 16 to rotate through the fixing plate 15 by using the rotating shaft 34 as a circle, and the function of rotating the screen 16 can be realized while the sliding base 11 reciprocates left and right.

The angle adjusting module works, in a plurality of clamping seats 41, one clamping seat 41 is always clamped in a limiting groove 45 of the screw sleeve 39, when the rotating shaft 34 rotates along with the horizontal movement of the sliding seat 11, along with the rotation of the rotating shaft 34, the rotating shaft 34 can drive the push column 46 to rotate, the push column 46 rotates to stretch the tension spring 42, along with the rotation, the push column 46 can be attached to the clamping seat 41 clamped in the limiting groove 45 and continuously rotates, the push column 46 can push the clamping seat 41 to slide out of the limiting groove 45, the push column 46 slides into the second sliding groove 40, after the push column 46 slides out of the limiting groove 45, the clamping seat 41 loses the limiting effect on the screw sleeve 39, and therefore the push column 46 can pull the screw sleeve 39 to rotate through the elastic recovery effect of the tension spring 42 until the limiting groove 45 rotates to the position of the next clamping seat 41, and the next clamping seat 41 can be clamped into the limiting groove 45 again. When the screw sleeve 39 is pulled by the pushing column 46 to rotate for an angle, because the sliding ring 32 is in threaded connection with the screw sleeve 39, the support rod 31 is limited by the sliding rod 30 to make the lifting ring 13 unable to rotate, so that the rotation of the screw sleeve 39 drives the sliding ring 32 to ascend or descend on the outer wall of the screw sleeve 39, so that the sliding ring 32 can push the support rod 31 to push the lifting ring 13 to ascend, and then because the rotating drum 37 is connected to the round sleeve 14 in a rotating manner, the handle 18 is arranged on the rotating drum 37, one end of the handle 18 extends into the slot 26, so as to drive the handle 18 to ascend or descend along with the ascending or descending of the lifting ring 13, so as to drive the rotating drum 37 to rotate on the round sleeve 14, the rotation of the rotating drum 37 can drive the fixing plate 15 to drive the screen 16 to rotate simultaneously, thereby realizing the function of adjusting the angle of the screen 16, and the angle adjustment at each time is realized along with the rotation of the screw sleeve 39 driven by the pushing column 46, the adjusted angle is the circumferential distance between every two clamping seats 41, and different angles of the screen 16 can be adjusted each time by setting different distances between the clamping seats 41.
