[0039] In some embodiments, referring to Figures 1 to 3 The Y-axis adjusting structure 6 includes a second adjusting structure 61 and a second locking structure 62. The second adjusting structure 61 penetrates through the column 2 and abuts against the base 1 along the Y-axis direction; and the second locking structure 62 penetrates through the column 2 to the base 1 along the Y-axis direction, and is used for locking the column 2 and the base 1. Specifically, the second adjusting structure 61 and the second locking structure 62 can be arranged as bolts. The second adjusting structure 61 penetrates through the column 2 and abuts against the base 1, and by screwing the second adjusting structure 61, the second adjusting structure 61 will generate a pushing force on the base 1, so that the column 2 can move along the Y-axis direction, so as to adjust the perpendicularity between the column 2 and the base 1 along the Y-axis direction.

[0040] In some embodiments, referring to Figures 1 to 3The Y-axis adjustment structure 6 includes several groups arranged along the circumference of the column 2. Specifically, six groups of Y-axis adjustment structures 6 are arranged along the X-axis on the front side of the column 2, two groups of Y-axis adjustment structures 6 are arranged on each of the left and right sides of the column 2, and six groups of Y-axis adjustment structures 6 are arranged along the X-axis on the rear side of the column 2. The arrangement of several groups of Y-axis adjustment structures 6 along the circumference of the column 2 allows the Y-axis adjustment structures 6 to more evenly and precisely adjust the gap between the column 2 and the base 1.

[0041] Further, refer to Figures 1 to 3 The Z-axis adjustment structure 5 includes two groups, one located on either side of the back of the column 2. Specifically, the two Z-axis adjustment structures 5 correspond to the two glue-filling areas 32. The two groups of Z-axis adjustment structures 5 are distributed on the left and right sides (X-axis direction) of the column 2. By adjusting the two groups of Z-axis adjustment structures 5, the position of the column 2 relative to the base 1 can be adjusted on both the left and right sides, preventing the column 2 from tilting.

[0042] refer to Figure 2 、 Figure 3 and Figure 6 The Y-axis adjustment structure 6 is used to adjust the installation position of the column 1 and the base 2. Specifically, the Y-axis adjustment structure 6 adjusts the verticality of the column 1 and the base 2 along the Y-axis direction. For example, when the column 2 is installed on the base 1, the column 2 may tilt to the left or right along the Z-axis direction (here Figure 6 direction as a reference), so that an inclination angle is generated between the column 2 and the base 1. Therefore, adjustment can be performed by using several groups of Y-axis adjustment structures 6 arranged circumferentially on the column 2. If the column 2 tilts to the left, the second locking structure 62 of the Y-axis adjustment structure 6 located on the right side of the column 2 is used to lock it, so that the column 2 fits against the right side of the base 1, so that the column 2 and the base 1 are straight; or, the second adjustment structure 62 of the Y-axis adjustment structure 6 located on the left side of the column 2 is used to push against the base 1, so that the column 2 is perpendicular to the base 1. Similarly, if the column 2 tilts to the right, the second locking structure 62 located on the left side of the column 2 is used to lock it, so that the column 2 is perpendicular to the base 1. In the process of adjusting the column 2 to be perpendicular to the base 1, any one or more groups of Y-axis adjustment structures 6 can be used for adjustment, with the column 2 being perpendicular to the base 1 as the standard.

[0043] refer to Figure 2 、 Figure 3 and Figure 7, the Z-axis adjustment structure 5 adjusts the parallelism of the column 2 and the base 1 along the X-axis direction, that is, the column 2 is as parallel as possible to the X-axis direction. For example, when the column 2 is installed on the base 1, the column 2 is not parallel to the X-axis direction. Then, the two groups of Z-axis adjustment structures 5 are used to adjust the column 2. If the column 2 is acute to the base 1 along the X-axis direction, the first adjustment structure 5 on the upper side (this time, the direction is the reference) is used to abut against the column 2, so that the column 2 is parallel to the X-axis direction. If the column 2 is obtuse to the base 1 along the X-axis direction, the first adjustment structure 5 on the lower side is used to abut against the column 2, so that the column 2 is parallel to the X-axis direction, so as to make the column 2 as parallel as possible to the base 1 along the X-axis direction. During the adjustment of the parallelism of the column 2 and the base 1, the column 2 is parallel to the base 1. Figure 7

[0044] In some embodiments, referring to Figures 1 to 3 The left side, the right side and the rear side of the column 2 are provided with the mounting groove 8 for arranging the Y-axis adjustment structure 6.

In this process, the column 2 is repeatedly adjusted (including pushing or pulling) by the first adjusting structure 51 and the second adjusting structure 61 until the assembly of the column 2 and the base 1 meets the installation technical requirements.

[0049] After the position of the column 2 is adjusted, the positioning structure 7 is inserted into the positioning groove for positioning to position the positions of the column 2 and the base 1. Then glue is injected into the glue pouring cavity through the injection channel 4, so that the gaps caused by the machining and assembly errors of the column 2 and the base 1 are filled with glue, and after the glue is solidified, the inlet of the injection channel 4 is sealed by a plug.

[0050] After the glue is filled, the column 2 and the base 1 are locked in the Z-axis direction by the first locking structure 52, and the column 2 and the base 1 are locked in the Y-axis direction by the second locking structure 62. Thus, the assembly of the column 2 and the base 1 is completed.
