This side in portion 34 also can have a fin 344, this elastic component 50 this fin 344 sheathed and this elasticity can be made
Part 50 positions, and this elastic component 50 has elastic energy and makes this block holding part 34 have and generally hit the direction of plate 41 towards this
The trend of movement.
In actual use, when this operating mechanism 20 by pressing operation from this primary importance P1 towards this
When two position P2 move, this block holding part 34 fastens this and hits plate 41 and this hits plate 41 from this initial position P3
Move towards this off-position P4, more carefully say, this operating mechanism 20 drive this this answer back to part 30 also
Interlocking this and hit plate 41, this hits plate 41 makes this elastic panel 43 store force deformation in moving process, and this hits
Plate 41 has and is available for clashing into the strength such as following closely pin.And when the operation of this operating mechanism 20 mobile to this second
During the P2 of position, this hits plate 41 and moves to this off-position P4 simultaneously, and this block holding part 34 hits plate 41 with this
Away from one another and this elastic panel 43 makes this hit plate 41 from this off-position P4 towards this initial position P3 shifting
Move and be available for clashing into nail pin.This hits plate storage force mechanisms 40 separately can include a buffer stopper 44, this buffer stopper 44
Being fixedly arranged on this housing 10, this buffer stopper 44 is positioned at below this elastic panel 43 and is adjacent to this mobile terminal 432,
It is preferred that hit plate 41 move to this initial position P3 from this off-position P4 when this, this buffer stopper 44 with
This elastic panel 43 produces the effect of buffering against each other, it is to avoid damage parts.This hits plate and stores force mechanisms 40
Separately can include an adjustment knob part 45, this adjustment knob part 45 is located at this housing 10, this adjustment knob pivotly
The side of part 45 is convexly equipped with a protuberance 451, and this adjustment knob part 45 is positioned one for rotation and compresses position, when
This adjustment knob part 45 be positioned this when compressing position, this protuberance 451 presses on the side of this elastic panel 43
And make this elastic panel 43 can produce bigger storage force deformation, make this hit plate 41 and can produce bigger impact force
Amount, has and adjusts the effect producing difference shock strength.This assembling machine 1 additionally comprises a nail kit 60, this nail kit
60 bottom sides being located at this housing 10, one end of this nail kit 60 has hits groove 61, and this nail kit additionally comprises multiple
Number row is located at the nail pin in this nail kit 60, the trend that such nail needle set moves towards this direction hitting groove 61, is somebody's turn to do
Hit plate 41 to be slidedly arranged on this and hit groove 61 can clash into such nail pin continuously by straight line.
In another embodiment as shown in Figure 8, it is sliding to face 333 and that this sliding part 33a can include one
Roller part 334, this roller part 334 is articulated mutually with this drive rod 22 and sliding this cunning that is butted on supports face 333, should
Operating mechanism 20 similarly can be driven by this sliding part 33a and answer back to part 30a, and by side as above
Formula drives this to hit plate 41 and produces the effect clashed into.
In another embodiment as shown in Figure 9, block holding part 34a can extend integratedly to be located at and answers back to part 30b
The second end 32a, this answers back to part 30b and has one and trackslip portion 35, and this housing 10 is installed with a hinged arm 14a,
This trackslip portion 35 slidably be sheathed on this hinged arm 14a pivotally, similarly pass through when this operating mechanism 20
Pressing operation from this primary importance P1 towards this second position P2 move time, this block holding part 34a fastens this and hits
Plate 41 and this hit plate 41 and move towards this off-position P4 from this initial position P3, and when this operating mechanism
20 operations mobile to this second position P2 time, this block holding part 34a hits with this that plate 41 is away from one another and this is elastic
Plate 43 makes this hit plate 41 to move towards this initial position P3 from this off-position P4 and be available for clashing into nail pin.
