[0002] After searching, it was found that the announcement number was CN210731076U, and the name was rectangular tube drilling positioning tooling. The application proposed that three holes need to be processed in the rectangular tube in the fork frame, and there is a height difference in the center of the holes. The tool needs to be adjusted up and down when drilling the holes, which is a cumbersome processing problem. By setting up supports with height differences, the rectangular tube is tilted at an angle to reduce production costs. At the same time, the height-adjustable supports with height differences are set to meet various production needs.

[0003] However, in actual use, the boring heads of this application are located on both sides of the rectangular tube. When drilling, only the two side surfaces of the rectangular tube can be drilled. When the hole position is located in the vertical direction, the staff is required to manually turn the rectangular tube over, which is rather troublesome. At the same time, this application can only adjust the inclination angle in the length direction of the rectangular tube, but cannot adjust the inclination angle of the side surface of the rectangular tube. The flexibility of use is not high and further improvements can be made.

[0004] The existing technology has the following problems:

[0005] 1. When the hole is vertical, the staff needs to turn it over manually, which is troublesome.
