[0035] like Figures 1 to 2 and Figure 4 As shown, each support assembly includes a support column 10 and a fixed seat 11. One end of the support column 10 is rotatably connected to the inside of the mounting bar 9. The support column 10 is designed to cooperate with the support column 2 12 to support the torsion body 1. The top end of the fixed seat 11 is fixedly connected to the bottom end of the support column 10. The fixed seat 11 is designed to facilitate the placement of other structures.

[0039] Working principle: When it is necessary to place the torsional vibrator on the screw pile foundation and let the torsional vibrator test the screw pile foundation, when testing is required, first fit the two clamps 2 together. Before fitting, press the pressing block 5 with your hand. The pressing block 5 will raise the driving column 6 to drive the card block 7, so that the card block 7 is retracted into the interior of the connecting seat 1 3. When the connecting seat 2 4 enters the interior of the connecting seat 1 3, the two clamps 2 are also fitted together. At this time, release the hand pressing the pressing block 5, and the spring 1 8 will push the pressing block 5, and the pressing block 5 will be pressed. The pressure block 5 will also drive the clamping block 7 through the driving column 6, so that the clamping block 7 can be re-engaged with the connecting seat 1 3, so that the connecting seat 1 3 and the connecting seat 2 4 are fixed together, and the two clamps 2 are also fixed together, so that the torsional exciter and the screw pile foundation are tightly fixed together. By allowing the clamping block 7 to engage with the connecting seat 1 3 under the drive, the connecting seat 2 4 and the connecting seat 1 3 are fixed together, and the two clamps 2 tightly hold the screw pile foundation together, the disassembly and assembly process is simpler, the disassembly and assembly time is shorter, and the detection efficiency is improved.

[0040] When the torsional vibrator is working, press the long plate 14 with your hand, so that the long plate 14 drives the long plate 2 15 and the clamping column 16 through the long rod 13, so that the clamping column 16 is separated from the support column 2 12, and the length of the support column 2 12 can be adjusted. When the adjustment is completed, release the hand pressing the long plate 14, and the spring 2 17 will push the long plate 14, thereby driving the long rod 13 and the long plate 2 15, so that the clamping column 16 and the support column 2 12 are re-engaged, thereby completing the adjustment of the length of the support column 2 12. After the length adjustment of the support column 2 12 is completed, the foot nail 18 is pressed into the ground, so that the support assembly supports the torsion body 1, and by allowing the clamping column 16 to engage and separate with the support column 2 12 under the drive of the long plate 2 15, the length of the support column 2 12 is adjusted, thereby better supporting the torsion body 1 and allowing the torsion body 1 to work more stably.
