Motor output shaft rotates；Motor output shaft rotation will drive support drive shaft turns by the second belt；Support driving shaft rotation
It is dynamic to drive saw blade rotation；I.e. saw blade works；When saw blade is triggered, driving motor is stopped；Support drive shaft will be along
When the arc groove sliding opened on guide plate, the second belt will unclamp；When what is opened on flexible gag lever post and drive connection plate
When limit hole is fully mated, the teeth on snap-gauge are just disengaged with the teeth on the downside of rack, and on the downside of the 6th wheel and rack
Teeth engage；At this time although driving motor is stopped, but motor output shaft also occurs that rotation under effect of inertia；At this time
Motor output shaft rotation will drive the rotation of third shaft by the first belt；The rotation of third shaft drives the rotation of the 4th gear；
The rotation of 4th gear drives the rotation of the 5th gear；The rotation of 5th gear drives the rotation of the 6th gear；6th gear rotation band moving teeth
Item moves；Rack movement will drive first gear, second gear, third gear and be drivingly connected plate movement；It is drivingly connected plate
Movement will drive saw blade to move down；So increasing the speed that sawtooth moves down in inertia rotatory force by motor output shaft
Degree；In the present invention in the initial state, position-limiting action is played to rack by snap-gauge.
Relative to traditional bench saw technology, the bench saw that the present invention designs accelerates saw blade by the transmission of rack and moves down
Speed；Prevent saw blade in locking process by the cooperation of the gag lever post that stretches, triggering driving plate, drive connection plate and saw blade simultaneously
Middle saw blade is ruined；Reduce the use cost of saw blade；The branch of saw blade is fixed during saw blade is triggered and moves down simultaneously
Spacing between support drive shaft and the motor output shaft of driving motor becomes smaller, and the second belt fluffs, to reduce driving motor
Damage.
