The rotating frame 4 is U-shaped, and the support frame 5 sets up the rotating frame 4. The rotating motor 3 is installed at one end of the rotating frame 4, and a bearing seat is installed at the end on the symmetrical side of the rotating motor 3. A tightening column 7 is installed in the axial hole of the bearing seat, and the tightening column 7 is hollow. The locking screw 6 passes through and tightens in the direction opposite to the rotating motor, and the 90° corner of the porous aluminum alloy bracket is locked on the rotating frame 4.

[0022] It also includes a base 8 and a support seat 9. The rotating frame 4 and the support seat 9 are installed on the base 8. The support seat 9 is divided into a horizontal support seat 90 and a vertical support seat 91. With the rotating axis of the rotating motor 3 as the center, the horizontal support seat 90 and the vertical support seat 91 are respectively arranged on the left and right sides. When the rotating frame 4 rotates to switch the angle, the horizontal part 1 and the vertical part 2 act on the horizontal support seat 90 and the vertical support seat 91 respectively.

[0023] A limiting column 10 is also provided on the base 8. The limiting column 10 is located on the base directly below the rotating frame 4 in a horizontal state. When the rotating frame 4 rotates 90° to change the direction of the porous aluminum alloy bracket, the limiting column 10 plays a role of supporting the rotating frame so that the rotating frame remains horizontal. It can also offset part of the pressure exerted on the parts by the drilling rig and the tapping machine, so as not to cause deformation of the suspended rotating frame.

[0024] The base 8 is provided with an opening window for the horizontal support seat 90 and the vertical support seat 91 to pass through. The lower ends of the horizontal support seat and the vertical support seat are provided with a lifter 12. The lifter 12 can hold the porous aluminum alloy bracket with the support seat, so that the parts will not shift when the drilling rig is drilling. The horizontal support seat is cylindrical, and a fixed column 911 embedded in the casting hole I is provided at the top, and a limit retaining ring with a diameter larger than the casting hole I is provided in the middle of the fixed column 911. The vertical support seat 90 is cylindrical, and a positioning column 901 embedded in the casting hole II is provided at the top, and a limit retaining ring with a diameter larger than the casting hole II is provided in the middle of the positioning column 901. There is a drilling distance between the limit retaining ring and the upper plane of the horizontal support seat and the vertical support seat. The support seat holds the horizontal part or the turned vertical part, which is convenient for drilling and tapping, and prevents the porous aluminum alloy bracket from shifting when facing a large pressure, thereby avoiding the occurrence of inaccurate drilling positions.

[0025] The positioning column 901 and the fixing column 91 can be replaced to adapt to porous aluminum alloy brackets of different sizes and specifications, and the lifter can also be replaced with other models with different strokes.
