[0042] Embodiment 2

[0043] The difference between this embodiment and the first embodiment is that the main bevel gear 4 and the auxiliary bevel gear 5 are replaced by a rotating wheel, and the rotating wheel is connected to the double-thread worm 6. The rotating wheel can drive the double-thread worm 6 to rotate, but the user needs to spend more effort to rotate the rotating wheel for a larger number of circles, and there is no acceleration structure. Therefore, the main bevel gear 4 and the auxiliary bevel gear 5 are preferred in this application.

[0044] The operating steps of the utility model are as follows: when the height needs to be adjusted, the main bevel gear 4 is rotated, and the main bevel gear 4 can drive the secondary bevel gear 5 to rotate. The size of the main bevel gear 4 is larger than that of the secondary bevel gear 5, which can produce an acceleration effect on the secondary bevel gear 5, and the secondary bevel gear 5 can drive the double-thread worm 6 to rotate. The teeth on both sides of the double-thread worm 6 have opposite directions, and the double-thread worm 6 can drive the two worm wheels 7 to rotate in the opposite directions. The worm wheel 7 on the left side rotates clockwise, and the worm wheel 7 on the right side rotates counterclockwise. The worm wheel 7 can drive the crankshaft 8 to rotate. The crankshaft 8 and the transmission frame 9 have an eccentric structure, and the crankshaft 8 can drive the transmission frame 9 to move. The crankshaft 8 is rotatably arranged with the transmission frame 9 through the bearing, and the transmission frame 9 can drive the limit frame 10 to retract into the interior of the shelf storage plate 3. At this time, the shelf storage plate 3 can be removed, and the shelf storage plate 3 can be moved to a suitable position and correspond to the adjusting holes 2 on both sides. Then, the manual mechanism is rotated in the opposite direction, which can drive the limit frame 10 to move outward, so that the limit frame 10 enters the interior of the adjusting hole 2.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
