the handle includes and moves handle, quiet handle, spring, move the handle and pass the bar hole on the circle and carousel fixed connection, rotate and move the handle and can drive the carousel and rotate, quiet handle is fixed on the circle and is close to the bar hole, the spring sets up and moves between handle and the quiet handle and with move the handle and link to each other with quiet handle.

Furthermore, the circle is provided with a circular cover plate on the side without the rotary table, the cover plate is fixed on the circle, and the center of the cover plate is provided with a circular hole which is opposite to the circular hole on the rotary table and has the same size.

Further, the blade and the gear are integrally formed.

The working process of the invention is as follows: inserting the rod-shaped object to be cut into the circular hole, holding the two handles by hands, moving the handles to drive the turntable to rotate in the forward direction, driving the plurality of blades to move towards the center simultaneously by the turntable, and simultaneously cutting the rod-shaped object from all directions while clamping the rod-shaped object by the plurality of blades; the handles are loosened, the two handles are opened under the action of the spring, the movable handles drive the rotating disc to rotate reversely, and the rotating disc drives the blades to move outwards simultaneously.

The invention has the beneficial effects that: when an object is sheared, the plurality of blades tightly clamp the sheared object, so that the sheared object cannot move, and the shearing surfaces are the same plane; especially when shearing hollow tubular object, because a plurality of blades are sheared to the object of being sheared simultaneously from all directions, the object periphery atress is balanced to be sheared, and the shear plane can not take place to warp.
