[0025] In operation, the bridge engineering detection steel bar pulling device in the above-mentioned technology is used to clamp and fix the steel bar by rotating the screw rod. However, the screw thread will be inevitably worn during the pulling detection of the steel bar. In the long-term use, the clamping and fixing effect of the steel bar will be poor due to the serious wear of the screw thread. The clamping piece 21 in the pulling pile 1 is replaced through the structural design of the clamping mechanism. The clamping piece 21 slides in the fixed groove 20 and is fixed by the clamping mechanism. The clamping piece 21 is replaced to ensure the clamping effect of the clamping piece 21 on the steel bar. When the clamping piece 21 is replaced, the rotating block 28 is first rotated to drive the rotating rod 27 to rotate. The rotating rod 27 is provided with multiple screw threads with opposite rotation directions. Therefore, the adjacent set of moving blocks 25 moves towards each other, thereby driving the connecting rod 23 inside the movable groove 22 to move until the connecting rod 23 is no longer inserted into the insertion hole 24. At this time, the abutment between the connecting rod 23 and the inner wall of the insertion hole 24 is eliminated, so that the clamping piece 21 can be easily pushed out of the fixed groove 20.
