[0041] First, the shift block 302 is manually pulled to move, and the shift block 302 drives the latch member 301 to move until the rear end of the slide groove 92 contacts the first limit block 304. At this time, the latch member 301 stops contacting the first connecting frame 3, and the truncated cone at the front end of the positioning block 306 is still located in the positioning hole 91. Then, the first connecting frame 3 is manually driven to rotate, so that the edge of the positioning hole 91 contacts the truncated cone surface of the positioning block 306, so that the first connecting frame 3 pushes the positioning block 306 to move, and the positioning block 306 compresses the first spring 305.

At this time, the first spring 305 rebounds and drives the positioning block 306 to move to the corresponding positioning hole 91. At this time, an obvious pause is felt manually, indicating that the first connecting frame 3 has been rotated into place. Then, the shift block 302 is manually pushed to move, and the shift block 302 pushes the latch member 301 to move, so that the latch member 301 is inserted into the corresponding positioning hole 91, and the second connecting column 2 and the first connecting frame 3 are fixed.

Figure 4 As shown, the support process will deviate, and then according to the deviation of the grid column and the supporting steel pipe, the first lever 204 is manually moved, and the first lever 204 drives the first screw rod 203 to rotate. Since the first screw rod 203 and the first sleeve 202 are screwed together, the first screw rod 203 drives the first sleeve 202 to move left or right, and the first sleeve 202 drives the first linkage block 201 to move left or right, so as to fine-tune the left and right positions of the second connecting column 2.

Therefore, before the first clamping block 5 clamps the grid column, the second connecting frame 403 is manually pulled upward to move, and the second connecting frame 403 drives the parts thereon to move upward, so that the third linkage block 401 moves upward, and the third linkage block 401 drives the undercut block 406 to move upward and contact the U-shaped block 405, and the undercut block 406 continues to buckle upward into the U-shaped block 405, thereby locking the third linkage block 401, starting the second motor 404, and the second motor 406 is engaged. 04 drives the second clamping block 402 to rotate, and the second clamping block 402 drives the third linkage block 401 to move, so that the third linkage block 401, the second clamping block 402 and the first clamping block 5 cooperate to clamp the lower end of the grid column, and then perform the adjustment operation. When in use, the lower end of the grid column is clamped by the third linkage block 401, the second clamping block 402 and the first clamping block 5, thereby increasing the clamping area and the clamping span of the grid column and avoiding deformation during the position adjustment of the grid column.
