A stapler that requires exertion of less effort comprising a body, an electric motor, a power supply, a power supply switch, a motion transmission mechanism having a gear cluster driven by the electric motor, a staple driving mechanism having a driving blade and a staple magazine driven by the motion transmission mechanism. The motion transmission mechanism comprises a rocking arm, and the rocking arm is a crank which is composed of a connecting shaft and a rocking shaft. The end of the connecting shaft connects to the top of the driving blade. The end of the rocking shaft is a gear, and the gear of the rocking arm has teeth which mesh with teeth of at least one gear of the gear cluster. The motion transmission mechanism comprises a double pole changeover switch and a micro switch.

What is claimed is: 1. A stapler that requires exertion of less effort comprising a body, an electric motor, a power supply, a power supply switch, a motion transmission mechanism having a gear cluster driven by the electric motor, a staple driving mechanism having a driving blade and a staple magazine driven by the motion transmission mechanism, which is characterized in that the motion transmission mechanism comprises a rocking arm, and the rocking arm is a crank which is composed of a connecting shaft and a rocking shaft, the end of the connecting shaft connects to the top of the driving blade, the end of the rocking shaft is a gear, and the gear of the rocking arm has teeth which mesh with teeth of at least one gear of the gear cluster; the motion transmission mechanism further comprises a double pole changeover switch and a micro switch; when the gear of the rocking arm swings to a first position which is the nearest to the front end of the staple magazine, the gear of the rocking arm contacts the micro switch; when the double pole changeover switch is actuated, an electric circuit is connected; the power supply provides electricity to the electric motor, and the electric motor rotates and drives the gear cluster to rotate and the gear of the rocking arm to swing upward to a second position; when the double pole changeover switch is deactivated, it changes the electric circuit to drive the electric motor to rotate reversely, the electric motor drives the gear cluster to rotate reversely and the gear of the rocking arm to swing downward until the gear of the rocking arm contacts the micro switch, the micro switch then disconnects the electric circuit, and the electric motor ceases to rotate. 2. The stapler that requires exertion of less effort as in claim 1, wherein the staple driving mechanism comprises a staple guiding plate which is engaged with the front end of the staple magazine and connects to a compression spring, the driving blade brings along the staple guiding plate to slide downward, and the compression spring brings along the staple guiding plate to follow the driving blade to slide upward back to its original position. 3. The stapler that requires exertion of less effort as in claim 1 or 2, wherein the staple driving mechanism further comprises a button, a fastener, an outer staple magazine, an inner staple magazine, and a spring; the button connects to the fastener, the fastener connects to and is engaged with the inner staple magazine, the inner staple magazine is disposed inside the outer staple magazine and is slidingly engaged with it, the spring connects with the inner staple magazine and the outer staple magazine; and by pressing the button, it drives the fastener to rotate until it is separated from the inner staple magazine, and the inner staple magazine ejects due to the spring effect; and by pushing in the inner staple magazine, it connects to and is engaged with the fastener again. 4. The stapler that requires exertion of less effort as in claim 1, wherein the gear of the rocking arm is in the form of an arc and has straight-cut teeth, and the number of teeth is 21 and it has a module of 0.6 and a standard pressure angle of 20��. 5. The stapler that requires exertion of less effort as in claim 1 or 4, wherein the gear of the rocking arm can swing back and forth and an angle is defined between the rocking shaft and a horizontal plane, the angle between the rocking shaft and the horizontal plane is between 100�� and 102��; the rocking shaft can swing along with the gear of the rocking arm and the angle between the rocking shaft and the horizontal plane is between 139�� and 141��. 6. The stapler that requires exertion of less effort as in claim 5, wherein the gear of the rocking arm is only required to swing back and forth by 37�� to 41�� respectively. 7. The stapler that requires exertion of less effort as in claim 5, wherein the gear of the rocking arm can also swing back and forth by 37�� to 80�� respectively. 8. The stapler that requires exertion of less effort as in claim 1, wherein the gear cluster comprises 1 driving gear and 4 driven gears; the driving gear has straight-cut teeth, a module of 0.6 and a standard pressure angle of 20��, and the number of teeth is 10, the driving gear connects to the electric motor and is driven by the electric motor; the driven gears comprise a first driven gear, a second driven gear, a third driven gear, and a fourth driven gear; the first driven gear comprises one big gear and one small gear each with straight-cut teeth and the two gears are disposed parallel to each other, the number of teeth of the big gear is 30 and the big gear has a module of 0.6, the number of teeth of the small gear is 19 and the small gear has a module of 0.6, and each of the two gears has a standard pressure angle of 20��, the big gear and the driving gear are intermeshed, and the first driven gear is driven by the driving gear; the second driven gear comprises one big gear and one small gear each with straight-cut teeth and the two gears are disposed parallel to each other, the number of teeth of the big gear is 34 and the big gear has a module of 0.6, the number of teeth of the small gear is 12 and the small gear has a module of 0.6, and each of the two gears has a standard pressure angle of 20��, the big gear of the second driven gear and the small gear of the first driven gear are intermeshed, and the second driven gear is driven by the first driven gear; the third driven gear comprises one big gear and one small gear each with straight-cut teeth and the two gears are disposed parallel to each other, the number of teeth of the big gear is 34 and the big gear has a module of 0.6, the number of teeth of the small gear is 12 and the small gear has a module of 0.6, and each of the two gears has a standard pressure angle of 20��, the big gear of the third driven gear and the small gear of the second driven gear are intermeshed, and the third driven gear is driven by the second driven gear; the fourth driven gear has straight-cut teeth, a module of 0.6 and a standard pressure angle of 20��, and the number of teeth is 38, the fourth driven gear and the small gear of the third driven gear are intermeshed, the fourth driven gear is driven by the third driven gear, and the fourth driven gear and the gear of the rocking arm are intermeshed. 9. The stapler that requires exertion of less effort as in claim 1, wherein the gear of the rocking arm is disposed inside the body near the front end of the staple magazine, and the gear cluster is disposed inside the body near the rear end of the staple magazine. 10.
