As shown in fig. 1 and fig. 2, the present embodiment provides a plane adjustment device disposed between a fixed plane 200 and a plane 100 to be adjusted, the plane adjustment device includes a positioning component 300, a leveling component 400 and an elastic pre-tightening component 500, wherein the positioning component 300 is used to enable the plane 100 to be adjusted to have a degree of freedom of rotation relative to the fixed plane 200, and a rotation axis of the plane 100 to be adjusted is parallel to the fixed plane 200; the leveling component 400 is used for leveling the plane 100 to be adjusted and can fixedly connect the plane 100 to be adjusted and the fixed plane 200; the elastic pre-tightening assembly 500 is connected to the plane to be adjusted 100 and the fixed plane 200, and is used for providing elastic pre-tightening force between the plane to be adjusted 100 and the fixed plane 200.

When the leveling operation needs to be performed on the plane 100 to be adjusted, the leveling component 400 can be operated to enable the plane 100 to be adjusted to rotate relative to the fixed plane 200 under the action of the positioning component 300, and the leveling operation on the plane 100 to be adjusted is realized through controlling the rotation amplitude of the plane 100 to be adjusted; when the leveling operation of the plane 100 to be adjusted is completed, the plane 100 to be adjusted is fixed to the fixing plane 200 by the leveling component 400, so as to achieve the purpose of leveling the plane 100 to be adjusted.

In the above process, since the elastic pre-tightening assembly 500 provides the elastic pre-tightening force, the plane 100 to be adjusted is in a state of being capable of floating relative to the fixed plane 200 during the leveling operation, so as to provide an adjustment margin for the leveling operation. In addition, since the plane 100 to be adjusted is kept in a mutually connected state with the fixed plane 200 through the elastic pre-tightening component 500, on one hand, for the situation that the plane 100 to be adjusted is located below the fixed plane 200 (as shown in fig. 1 and fig. 2), the arrangement can ensure that the plane 100 to be adjusted does not break away from the fixed plane 200 in the leveling process, so that a worker is not required to lift the plane 100 to be adjusted all the time in the leveling operation, the situation that the leveling operation cannot be carried out smoothly due to the fact that the gravity of the plane 100 to be adjusted is too large is avoided, meanwhile, the leveling difficulty is reduced, the leveling operation of the plane 100 to be adjusted is simple, and adverse effects on the leveling operation caused by machining precision and installation level are also reduced; on the other hand, in the case that the plane 100 to be adjusted is located above the fixed plane 200 (in this case, not shown in the figure), the above arrangement can prevent the plane 100 to be adjusted from shifting during the leveling process, and even if the plane 100 to be adjusted receives external forces from other directions during the leveling process, the plane will not deviate from the fixed plane 200, thereby avoiding adverse effects on the leveling process due to external force interference, reducing requirements on the leveling environment, and also simplifying the leveling operation.
