The center of the bending disc is connected to the bottom plate through a fixed shaft. Two protruding connection parts extend from a straight edge of the bending disc toward the direction of the bottom plate, and are connected to the bottom plate through fasteners.
The semicircle of the bending disc determines that the maximum bending angle of the pipe and the steel bar is 180 degrees. At the same time, three fixed points, two connecting parts and the fixed shaft are arranged below the bending disc to ensure the strength and durability of the whole bending disc.
Preferably, the rotary arm includes a rotating part rotatably connected to the fixed shaft, a hand lever located at a tail end of the rotating part, and the bending abutting block arranged on the rotating part. The rotating part is provided with a connector configured to connect an external power piece.
Preferably, the clamping assembly includes a base fixedly arranged on the bottom plate, a connecting rod arranged on the base, and a handle hinged to a tail end of the connecting rod and the base. The other end of the connecting rod is provided with an abutting joint, which is driven by the connecting rod to move close to or away from the bending disc. A middle part of the handle is hinged with the connecting rod, and a tail end thereof is hinged with the base, so that two hinged points on the handle and the tail end of the connecting rod form a triangular structure.
Preferably, the clamping block is provided with a curved groove configured to abut against a pipe head.
