The first direction is... Figure 1 The top and bottom directions, the second direction is Figure 1 The left and right directions in the middle, and the third direction is... Figure 1 The front and back directions in the middle;

[0038] like Figure 1 , Figure 3 and Figure 5 As shown, the plate 4 is initially fixed by the first connecting seat 51 and the second connecting seat 53. Since the axial direction of each mounting hole of the plate part is the same, the extension direction of the first connecting seat 51 is also the same.

Therefore, after the position of the insertion channel 32 is adjusted by the three-axis adjustment mechanism 2, the position of the insertion channel 32 is ensured to correspond with the mounting hole position of the plate part, thus realizing the rapid installation of the plate part. Moreover, the above structure is simple, and rapid installation can be achieved by adjusting the three-axis adjustment mechanism 2 through the automatic control system.
