Long and thin rod labor-saving cutting device facilitating power coordination

The invention provides a long and thin rod labor-saving cutting device facilitating power coordination. The long and thin rod labor-saving cutting device comprises a base, two side clamps arranged at the two ends of the base correspondingly, a middle clamp and a cutting device which are arranged between the two side clamps and coaxial with the two side clamps, and a hand-cranking driving mechanism for driving the cutting device to rotate and feed. The hand-cranking driving mechanism comprises a rocker, a driving shaft, a high-speed shaft and a low-speed shaft, the high-speed shaft transmits torque to a high-speed hollow shaft which is horizontally arranged on the base through a reversing mechanism, and the high-speed hollow shaft drives the cutting device to rotate; the low-speed shaft is driven by a reversing mechanism to transmit torque to a low-speed hollow shaft lying on the other side of the base, the low-speed hollow shaft and the high-speed hollow shaft are the same in rotating direction but have a rot
