Then, the hand wheel 210 is fixedly installed with the screw rod 21. The screw rod 21 is threadedly connected with the threaded hole 20.

[0050] When it is necessary to cut prestressed pipe piles of different thicknesses, the collar 1 is sleeved on the prestressed pipe pile, and the handwheel 210 is manually rotated to make the clamping plate 211 closely fit the outer wall of the prestressed pipe pile. With the cooperation of the rubber pad 213, the friction force is increased for fixation. After the fixation is completed, the fastening bolt 511 is manually loosened, and the position of the adjusting plate 3 is moved so that the right end of the adjusting plate 3 is closely close to the outer wall of the prestressed pipe pile. Then the fastening bolt 511 is tightened to fix the positions of the adjusting plate 3 and the rotating plate 5. According to the required cutting depth, the wrench is manually turned to rotate the adjusting rod 33, driving the movable plate 4 to move, and the cutting knife 410 cuts to the required cutting depth to achieve the cutting of the prestressed pipe pile. Then, with the cooperation of the handle 34, the user holds the handle 34 and pushes it to rotate, so that the cutting knife 410 rotates around the collar 1 to achieve stable cutting cooperation around the sleeved prestressed pipe pile. After the cutting is completed, the wrench is turned in the reverse direction, and the movable plate 4 is taken away from the cutting outer wall of the prestressed pipe pile. Then the handwheel 210 is rotated to make the clamping plate 211 away from the prestressed pipe pile, which helps to take out and replace the whole. The overall operation is simple and convenient for quickly cutting prestressed pipe piles.
