Also comprise one and regulate the regulating shaft of said alignment pin position.
Said regulating shaft comprises the eccentric structure that rotates of stirring with said knob that is suitable for the different quality saw blade is stirred knob, the other end setting of adjusting of an end setting, comprise on the said eccentric structure a plurality of can with the contacted eccentric adjusting face of said alignment pin.
Said alignment pin one end penetrates in the said connecting rod, and the other end contacts with said eccentric structure.
Said connecting rod sheathed axle sleeve on said alignment pin rotates.
Comprise one on the said eccentric structure and rotate and can snap in the locking projection in the locking hole of balance weight one end with it.
When the rotation of said eccentric structure drove in the locking hole that said locking projection inserts said balance weight one end, said eccentric structure promoted said alignment pin and moves up and down to making the recess on the said connecting rod other end be positioned at said interlock hole.
The beneficial effect that the present invention reached:
Multifunctional saw of the present invention is through the adjusting of the balance adjustment structure that is made up of balance weight, connecting rod, alignment pin, regulating shaft; The motion of balance weight and saw blade is balanced each other; Vibration when effectively reducing the saw blade cutting; Improve operating personnel's comfort, thereby further reduce operating personnel, increase work efficiency because of the hand sense of fatigue that vibration causes.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Like Fig. 1, shown in Figure 2, multifunctional saw body of tool 1 of the present invention drives driver element 6 by motor, and driver element 6 will rotatablely move through eccentric structure and be delivered to shift fork 5, and shift fork 5 is connected with main shaft 3, and main shaft 3 drives saw blade 7 and rotatablely moves.
For vibration balancing; The present invention is provided with a balance regulator 4 on multifunctional saw; Comprise that connecting rod 8, an end that an end 81 inserts in the jack 51 on the shift fork 5 penetrate alignment pin intracardiac in the connecting rod 8 11; Be connected through an axle sleeve 10 between alignment pin and the connecting rod 8, connecting rod 8 can be rotated around alignment pin 11 through axle sleeve 10, bar linkage structure is as shown in Figure 3.Connecting rod 8 other ends 82 insert in the interlock hole 21 of balance weight 2 one ends, and balance block structure is as shown in Figure 5, balance weight 2 one ends and the interlock hole 21 adjacent locking holes 22 that also are provided with.Regulating shaft 12 eccentric structures 121 are provided with a locking projection 123, and locking projection 123 can snap in the locking hole 22 of balance weight 2 one ends.
Connecting rod 8 one ends 81 embed in the jack 51 of shift fork 5, when shift fork 5 is stirred by driver element 6 drivings, and then axle sleeve 10 rotations of drivening rod 8 one ends 81 on alignment pin 11, connecting rod 8 other ends rotate thereupon and drive balance weight 2 around shift fork 5 rotations.When clockwise direction rotated when shift fork 5 was promptly overlooked by the direction of A shown in Fig. 2, driving main shaft 3 clockwise rotated, and the saw blade 7 on the main shaft 3 clockwise rotates thereupon; At this moment; The rotation of shift fork 5 drivening rods 8 one ends, connecting rod 8 direction of rotation are B direction shown in Fig. 2, connecting rod 8 other ends 82 insert in the interlock hole 21 of balance weight 2; The rotation of connecting rod 8 then drives balance weight 2 and rotates counterclockwise around main shaft 3; Balance weight 2 is opposite with the direction of rotation of saw blade 7, thereby realizes balance exercise, the vibration that produces when offsetting saw blade 7 motions.
Balance regulator 4 can carry out balance adjustment according to the quality of different saw blades 7, and the knob 122 that regulating shaft 12 is provided with in the present embodiment is 4 grades, when different quality saw blade 7 is regulated; Can reach the effect of balance through adjusting knob 122; Concrete mode is following: eccentric structure 121 is corresponding on the regulating shaft 12 is provided with four different eccentric adjusting faces 124, relies on different adjustment face 124 positions of eccentric structure 121 on the regulating shaft 12 to contact with alignment pin 11, like this position difference that moves up and down of alignment pin 11; The position that its drivening rod 8 other ends 82 insert in the balance weight 2 interlock holes 21 is also different; When connecting rod 8 rotational angles were constant, did not wait in the path that the diverse location place rotates on the connecting rod 8, and the rotation amplitude of balance weight 2 is different; Thereby can realize that balance weight 2 matches with the rotation amplitude of saw blade 7, reaches statokinetic adjusting purpose.
The other end 82 that connecting rod 8 inserts balance weight 2 is provided with flat position 83, two places; When not needing vibration balancing; Can stir knob 122 makes regulating shaft 12 turn to 0 gear; At this moment, the eccentric structure 121 of regulating shaft 12 is adjusted to alignment pin 11 flat 83 interlock hole 21 that is positioned at balance weight 2, two places of drivening rod 8 just; Locking projection 123 on the eccentric structure 121 of regulating shaft 12 is rotated in the locking hole 22 that snaps in balance weight 2 one ends just simultaneously, balance weight 2 stop motions this moment.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
