[0027] When in use: the gear ring 7 and the mounting column 6 are driven to rotate by the driving wheel 8, which drives the mounting seat 3 to rotate, and then drives the clamping seat 2 above the mounting seat 3 to rotate, so as to achieve the angle adjustment of the clamping seat 2 and the parts fixed above the clamping seat 2 in the horizontal plane, and the horizontal adjustment angle of the parts is controlled by the change of the angle between the first pointer 4 and the first dial 5.

[0028] Reference Figure 1 , Figure 3 , Figure 5 Two groups of symmetrically distributed mounting frames 10 are provided in the mounting seat 3, and slide rails 13 are provided on both groups of mounting frames 10.

The two groups of slide rods 12 are arranged corresponding to the mounting frames 10, and the slide rods 12 are slidably connected with the mounting frames 10 through the slide rails 13. A mounting shaft 16 is fixedly installed on the adjusting rod 11, and the adjusting rod 11 is rotatably connected with the mounting frame 10 through the mounting shaft 16. Two groups of symmetrically distributed racks 18 are provided in the mounting seat 3, and a cylinder 20 is provided in the mounting seat 3. Two groups of symmetrically distributed gears 17 are sleeved on the mounting shaft 16, and the racks 18 are meshed and connected with the corresponding gears 17.

[0029] During use: the rack 18 is driven to slide by the cylinder 20, and the mounting shaft 16 is rotated in cooperation with the gear 17. The mounting shaft 16 drives the adjusting rod 11 and the clamping seat 2 above the adjusting rod 11 to be stable during the longitudinal angle adjustment process under the action of the slide rod 12 and the mounting frame 10. The longitudinal angle adjustment of the parts on the clamping seat 2 is controlled by the change in the angle between the second pointer 14 and the second gear disc.

Under the action of the slide bar 12 and the mounting frame 10, it is ensured that the mounting shaft 16 drives the adjusting rod 11 and the clamping seat 2 above the adjusting rod 11 to be stable during the longitudinal angle adjustment process. The longitudinal angle adjustment of the part on the clamping seat 2 is controlled by the change of the angle between the second pointer 14 and the second gear disc, thereby realizing multi-angle adjustment of the part fixed on the clamping seat 2 to facilitate its multi-angle processing on the boring machine.
