The utility model discloses basic scheme's principle and beneficial effect lie in:

the workpiece to be bent is placed between the movable plate and the fixed plate, the threaded rod is rotated, the movable plate moves towards the direction of the fixed plate under the action of thread transmission to clamp the workpiece to be bent, the rotating shaft of the rotating arm is inserted into the rotating hole of the fixed die, meanwhile, the threaded push rod on the rotating arm is rotated, the threaded push rod pushes the movable die to slide in the inverted T-shaped groove to clamp the workpiece to be bent, and the rotating arm is rotated to enable the movable die on the rotating arm to rotate around the rotating hole of the fixed die to bend the workpiece. Because the movable mould can slide on the rotating arm to be nearest to the fixed mould when clamping the workpiece, the power arm is maximized, the resistance arm is minimized, the resistance of the elbow is reduced, and the purpose of optimal labor saving is achieved.

The manual pipe bending device is small in size, does not occupy a field, is simple in structure and convenient to operate, and is suitable for pipe bending of different diameters.

Further, as the optimization of the basic scheme, an arc-shaped T-shaped groove concentric with the fixed die and a T-shaped screw rod in sliding fit with the arc-shaped T-shaped groove are arranged on the bottom plate, and a nut for fixing the T-shaped screw rod and the bottom plate is arranged on the T-shaped screw rod.

The T-shaped screw rod slides to a set position along the arc-shaped T-shaped groove, the T-shaped screw rod and the bottom plate are fixed by screwing the nut, and therefore the workpiece is bent to be in contact with the T-shaped screw rod every time, and the workpiece can be bent to be at the same angle.

Further, a rolling sleeve is sleeved outside the fixed die and is rotatably connected with the fixed die.

When the pipe bending operation is carried out, the rolling sleeve rolls along the surface of the workpiece, so that the fixed die is prevented from sliding along the surface of the workpiece when the pipe bending operation is carried out, and scratches possibly generated on the surface of the workpiece are prevented.

Further, the rolling sleeve is made of plastic.

Because the hardness of the plastic is less than that of the workpiece, the rolling sleeve can not generate indentation on the surface of the workpiece when rolling along the surface of the workpiece.

Further, one end, far away from the fixed die, of the rotating arm is provided with a holding part, and the shape of the holding part is processed into a cylinder.

The one end that the cover half was kept away from to the swinging boom is processed into the cylinder, conveniently grips the swinging boom and breaks curved processing off with the fingers and thumb to the work piece, when breaking off with the fingers and thumb the curved operation and needing bigger power, can put on with the long pipe of cylinder complex in the outside of cylinder, the extension is broken off with the fingers and thumb the power arm and then is played the afterburning effect.

Furthermore, a distance of 5mm to 10mm is reserved between the lower end face of the movable die and the bottom plate.

And a distance is set between the lower end surface of the fixed die and the bottom plate, and when the movable die rotates around the center of the fixed die to bend the pipe, the lower end of the movable die cannot contact with the bottom plate to influence the rotation of the movable die.
