Laminating wood, has reached the function of quickly sawing wood；The effect of second spring is after lumbering arm has worked, to guide post one
Active force, makes drive mechanism return to original position；When arm of lumbering works, trees press the scroll saw between the first directive wheel,
Under the pulling of scroll saw, the guide post now installed in pilot hole can guide drive device to be moved along pilot hole, make on steel wire rope
The contact with wood maximum magnitude of sawtooth unit so that compensate trees parcel scroll saw；When lumbering arm does not work, installed in guarantor
The second directive wheel on frame is held, is remained stationary as all the time in existing position under the supporting role of retainer, but can be around circle
Pin rotates, and plays a part of supporting scroll saw；When arm contact of lumbering is to wood, wood meeting line ball is sawed, the guiding in drive mechanism
Bar is slided along pilot hole, and the grip slide on clamping plate is moved along the guide rail on casing, the first directive wheel is guided scroll saw parcel
Wood；When lumbering arm starts to saw wood, scroll saw can surround wood round and round, reach that scroll saw is contacted with wood maximum magnitude, now
Belt is located at the first belt pulley major diameter and at the second belt pulley minor diameter, makes the rotating speed of driving wheel very high, such scroll saw is just
Reach the function of quickly cutting wood；When soon having cut wood, due to the belt push rod on the first casing not
It is dynamic, belt can be pulled axially movable, belt is located at the first belt pulley minor diameter and at the second belt pulley major diameter, driving
Wheel speed is reduced, it is therefore an objective to is facilitated staff to watch trees toppling direction, is reached the purpose of protection staff；First spring
Effect be lumbering arm worked after, give clamping plate one active force, clamping plate is returned to original position.

Slide, the grip slide on clamping plate 1 is moved along the guide rail 9 on casing, the first directive wheel 3 is guided the parcel wood of scroll saw 44；
When lumbering arm starts to saw wood, as shown in figure 14 c, scroll saw 44 can surround wood round and round, reach scroll saw 44 and the maximum model of wood
Contact is enclosed, now belt 26 is located at the major diameter of the first belt pulley 24 and at the minor diameter of the second belt pulley 27, makes driving wheel 16
Rotating speed is very high, and such scroll saw 44 just reaches the function of quickly cutting wood；When soon having cut wood, due to installed in
Belt push rod 28 on one casing 4 is motionless, can pull belt 26 axially movable, belt 26 is located at the first belt pulley 24 small straight
At footpath and at the major diameter of the second belt pulley 27, the rotating speed of driving wheel 16 reduction, it is therefore an objective to facilitate staff to watch the trees side of toppling over
To, reach protection staff purpose；The effect of first spring 5 is after lumbering arm has worked, to give clamping plate 1 one effects
Power, makes clamping plate 1 return to original position.
