It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

As shown in fig. 1 to 8, 10 and 12, the multidirectional adjusting apparatus of the present embodiment includes: a first steering structure 10 and a second steering structure 20. The first steering structure 10 includes a first mount 11, a rotating member 12 provided on the first mount 11, a steering lock hook 13 movably provided on the rotating member 12, and a first driving member 14 and a second driving member 15 provided in the rotating member 12. The first driving member 14 is capable of driving the steering lock hook 13 to move toward a first direction, and the second driving member 15 is capable of driving the steering lock hook 13 to move toward a second direction opposite to the first direction. The rotation member 12 can drive the direction-adjusting latch hook 13 to rotate when rotating, so that the direction-adjusting latch hook 13 has a locking position and an unlocking position. The second direction-adjusting structure 20 includes a second mounting seat 21 and an adjusting rod 22 disposed in the second mounting seat 21, and is engaged with the adjusting rod 22 when the direction-adjusting latch hook 13 rotates to the locking position (shown in fig. 10), and is separated from the adjusting rod 22 when the direction-adjusting latch hook 13 rotates to the unlocking position (shown in fig. 12).

By applying the technical solution of the present embodiment, the first direction-adjusting structure 10 may be installed on one of the two adjacent boxes 30, and the second direction-adjusting structure 20 may be installed on the other of the two adjacent boxes 30. In this embodiment, when the direction-adjusting latch hook 13 is at the locking position, the first driving member 14 drives the direction-adjusting latch hook 13 to move towards the first direction, so that the direction-adjusting latch hook 13 drives the adjusting rod 22 to move towards the first direction to adjust the distance between the first direction-adjusting structure 10 and the second direction-adjusting structure 20, and further, the gap between two adjacent boxes 30 can be adjusted. Or when the second driving piece 15 drives the direction-adjusting latch hook 13 to move towards a second direction opposite to the first direction, the direction-adjusting latch hook 13 drives the adjusting rod 22 to move towards the second direction, so that the distance between the first direction-adjusting structure 10 and the second direction-adjusting structure 20 can be adjusted again, and the gap between two adjacent boxes 30 can be adjusted. Then, the adjusting lever 22 rotates and pushes the direction adjusting latch hook 13 to move along the axial direction of the adjusting lever 22 to adjust the distance between the first direction adjusting structure 10 and the second direction adjusting structure 20, thereby being capable of adjusting the height difference between the adjacent two cases 30. Like this, can adjust the gap between two adjacent boxes 30 through a set of multidirectional adjusting device, can adjust the difference in height between two boxes 30 again, the function is various. Therefore, the technical scheme of the embodiment can solve the problem that the function is single by only adjusting the gap between the adjacent boxes in the related technology.

The limiting member 16 defines the direction-adjusting latch hook 13 to prevent the direction-adjusting latch hook 13 from being separated from the rotating member 12 during the process of switching the direction-adjusting latch hook 13 between the unlocking position and the locking position. Meanwhile, the limiting piece 16 can limit the moving range of the direction-adjusting latch hook 13, so that the direction-adjusting latch hook 13 can conveniently move along the axis direction perpendicular to the adjusting rod 22.

As shown in fig. 2 to 4 and 8, the rotating member 12 is provided with a first limiting hole 121, and the direction-adjusting latch hook 13 is provided with a second limiting hole 131 correspondingly matched with the first limiting hole 121. The axis of the first limiting hole 121 is perpendicular to the moving direction of the steering latch hook 13, and the limiting member 16 includes an elastic member. The elastic member is located in the first limiting hole 121 and the second limiting hole 131. The first limiting hole 121 and the second limiting hole 131 are arranged to enable the rotating member 12 to have an installation space, and the rotating member 12 can accommodate the limiting member 16, so that the first direction adjusting structure 10 is compact in structure. The elastic piece has elasticity, when the direction-adjusting latch hook 13 is in the locking position, the first driving piece 14 drives the direction-adjusting latch hook 13 to move towards the first direction, and the elastic piece deforms leftwards along with the movement of the direction-adjusting latch hook 13, so that the direction-adjusting latch hook 13 drives the adjusting rod 22 to move towards the first direction. Or when the second driving piece 15 drives the direction-adjusting latch hook 13 to move towards a second direction opposite to the first direction, the elastic piece deforms rightwards along with the movement of the direction-adjusting latch hook 13, so that the direction-adjusting latch hook 13 drives the adjusting rod 22 to move towards the second direction. In the two processes, the elastic member always applies a spreading force to the direction-adjusting latch hook 13, so that the direction-adjusting latch hook 13 can be in contact with the rotating member 12, and looseness is prevented when the direction-adjusting latch hook 13 moves towards the first direction or the second direction.

When neither the first driving member 14 nor the second driving member 15 drives the direction-adjusting latch hook 13 to move, and both the first driving member 14 and the second driving member 15 are separated from the direction-adjusting latch hook 13, the direction-adjusting latch hook 13 can be quickly reset under the action of the self elastic force of the elastic member.

The first limiting hole 121 of the present embodiment includes a through hole section located at the rear side of the second limiting hole 131 and a blind hole section located at the front side of the second limiting hole 131.
