The second adjustment mechanism 20 is disposed at a distance from the first adjustment mechanism 10. The second adjusting mechanism 20 includes a second adjusting sleeve 21 and a second operating member 22 disposed on the second adjusting sleeve 21, an axis of the second adjusting sleeve 21 extends along the Y-axis direction, the second operating member 22 is movably disposed in the second adjusting sleeve 21 along the Y-axis direction, a locking groove 221 is disposed on the second operating member 22, and the locking member 13 includes a hook 131 capable of being engaged with the locking groove 221. The rotation member 12 rotates to drive the locking member 13 to rotate synchronously, so that the hook head 131 of the locking member 13 has an unlocking position separated from the locking groove 221 and a locking position matched with the locking groove 221, when the hook head 131 is at the locking position, the second operation member 22 moves to enable the side wall of the locking groove 221 on the second operation member 22 to push the hook head 131 to move along the Y axis direction, and when the gear part 31 on the first operation member rotates, the rack part 32 on the locking member 13 is pushed to move along the direction perpendicular to the Y axis direction, so that the first adjustment sleeve 11 and the second adjustment sleeve 21 are close to each other or far from each other.

By applying the technical solution of the present embodiment, the first adjusting mechanism 10 may be mounted on one of the two adjacent frames 61, and the second adjusting mechanism 20 may be mounted on the other of the two adjacent frames 61. In this embodiment, when the rotating member 12 rotates, the locking member 13 is driven to rotate synchronously, so that the hook 131 of the locking member 13 has an unlocking position separated from the locking slot 221 and a locking position matched with the locking slot 221, when the hook 131 is at the locking position, an operator operates the second operating member 22 to move so that the side wall of the locking slot 221 on the second operating member 22 pushes the hook 131 to move along the Y-axis direction, so that the second adjusting mechanism 20 moves along the Y-axis direction relative to the first adjusting mechanism 10, and the height difference between the frame 61 where the second adjusting mechanism 20 is located and the other frame 61 is adjusted. And the gear portion 31 on the first operating member pushes the rack portion 32 on the locking member 13 to move in the direction perpendicular to the Y axis when rotating, so that the first adjusting sleeve 11 and the second adjusting sleeve 21 are close to or far from each other, the distance between the first adjusting mechanism 10 and the second adjusting mechanism 20 in the direction perpendicular to the Y axis can be reduced or increased, and the gap between the frame 61 where the first adjusting mechanism 10 is located and the other frame 61 can be adjusted. Thus, the height difference between the two frames 61 can be adjusted through the adjusting device of one set of frames, and the gap between the two adjacent frames 61 can be adjusted, so that the device has multiple functions. Therefore, the technical scheme of the embodiment can solve the problem that the function is single by only adjusting the gap between adjacent frames in the related technology.

In the present embodiment, the Y-axis direction is the front-rear direction, and the direction perpendicular to the Y-axis is the Z-axis direction (up-down direction), but in other embodiments, the direction perpendicular to the Y-axis also means the X-axis direction (left-right direction).

As shown in fig. 1 to 3, when the distance between the first adjusting mechanism 10 and the second adjusting mechanism 20 along the direction perpendicular to the Y-axis is reduced or increased to a distance meeting the assembly requirement of the frame 61, in order to prevent the first operating member from loosening along the Y-axis, the rotating member 12 is movably provided with a locking member 33, and the locking member 33 has a locking position for abutting against the first operating member and a retracting position for retracting the first operating member. Thus, when the locking member 33 is in the locking position, the first operating member can be limited to move along the Y-axis direction, so that the working position of the first operating member is unchanged relative to the rack portion 32, and when the locking member 33 is in the yielding position, the locking member 33 is separated from the first operating member, so that the first operating member can still loose along the Y-axis direction, and the rack portion 32 on the locking member 13 is pushed to move along the direction perpendicular to the Y-axis when the gear portion 31 on the first operating member rotates.

Thus, when the operator inserts the first operation hole 1221 to rotate by using the operation tool, the operation block 122 can be driven to rotate, and because the operation block 122 is in rotation-stopping fit with the inner hole of the rotary cylinder 121, the rotary cylinder 121 can be driven to rotate together, and when the rotary member 12 rotates, the locking member 13 can be driven to rotate synchronously. When the operator rotates by inserting the operating tool into the second operating hole 141, the operating lever rotates around the Y-axis direction relative to the operating block 122, and further drives the gear portion 31 on the first operating member to rotate.

When the locking member 13 is adjusted in place by the rack portion 32, the locking member 33 is then adjusted by a hexagonal wrench to switch from the retracted position to the locked position to press the operating lever to the full lock. When the locking piece 33 is to be unlocked, the locking position is firstly adjusted by using the hexagonal wrench to switch to the back-off position, the operating rod can freely rotate, the operating rod is rotated to drive the locking piece 13 to move and contact with the hooking state, the first limiting piece 41 is synchronously rotated to avoid the position which is in limit fit with the third limiting piece 43, the rotating piece 12 can freely rotate, the rotating piece 12 is rotated to the initial position by using the hexagonal wrench, the first limiting piece 41 is synchronously moved to the position which is in limit fit with the second limiting piece 42 to lock the rotating piece 12, the rotating piece 12 is prevented from freely rotating, and the hook 131 of the locking piece 13 is switched to the unlocking position from the locking position.
