Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail:
Refering to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention has fool proof collapsible saw
Cut an embodiment of machine, comprise 20, the sawing of 10, buck of a base unit
Unit 30 and a safety device 40.
This base unit 10 has a cephalolateral margin 11, in contrast to this cephalolateral margin 11
Posterior lateral margin 12, one is extended to 13, one, the bottom surface of this posterior lateral margin 12 by this cephalolateral margin 11
End face 14 in contrast to this bottom surface 13.For structure, this base unit 10 also has one
Individual 15, two runners 16 being radially connected to these base 15 both sides of base in the form of annular discs,
And this cephalolateral margin 11, this posterior lateral margin 12 are common by this base 15 and described runners 16 respectively
Producing, this end face 14 is arranged at described runners 16 top.
This buck 20 is installed on the base 15 of this base unit 10 and between described runners
Between 16, can rotate relative to this base unit 10, and there is one in contrast to this bottom surface
13 and corresponding to this end face 14 work surface 21, corresponding to this posterior lateral margin 12 and connect
It is reversed with this axle bed 22 in the axle bed 22 of this work surface 21 and one and can extend outwardly
Buck operating handle 23, this axle bed 22 has one and is parallel to this work surface 21 and by this
Axis L that posterior lateral margin 12 extends towards this cephalolateral margin 11, an operable alignment pin 221 and
One along this axis L arrange rotating shaft 222, this rotating shaft 222 have one to should rear side
Edge 12 and be located at the scarfing unit 223 of end, this scarfing unit 223 is perpendicular to cutting of this axis L
Face is non-round shape.
This sawing unit 30 has an axle bed 22 being located in this buck 20 and can be relative to
The tumbler 31, one that this base unit 10 and this buck 20 rotate is articulated in this tumbler
The support arm of 31 32, one be installed on the saw blade 33 of this support arm 32 and one be installed on this
Support arm 32 and for driving the driver 34 that this saw blade 33 rotates.This tumbler 31 axle
It is located at this rotating shaft 222, and this support arm 32 can be driven relative for center of rotation with this axis L
Rotating with this buck 20 in this base unit 10, this tumbler 31 has one and is parallel to this
Axis L and this tumbler 31 can be locked in the keeper 311 of this axle bed 22, Shuo Geneng
Supply this alignment pin 221 inlay card and be respectively separated the hole clipping 312,313,314 of predetermined angle, should
Hole clipping 314 is in long arc-shaped.
This safety device 40 is corresponding to the posterior lateral margin 12 of this base unit 10, and has one
The contact pressing piece 41 and a connection positioned is produced relative to this buck 20 or this base unit 10
Sensing member 42 in the tumbler 31 of this sawing unit 30.In the present embodiment, this contact pressing piece
41 is plate-shaped and be fixedly arranged on this rotating shaft 222, and have one and be nested in this scarfing unit 223
Non-circular fixing hole 411 and one are convexly equipped in periphery and the portion that presses 412 in flange shape, should
Sensing member 42 can use microswitch, and have one and press portion 412 corresponding to this and can be subject to
This presses the detecting part 421 that portion 412 presses.
The most as shown in Figures 1 to 4, show that this sawing machine is positioned at a duty, at this
Under state, this driver 34 is suspended at above the work surface 21 of this buck 20, when treating cut
When part is positioned over this work surface 21, the support arm 32 operating this sawing unit 30 is utilized to drive
This saw blade 33 and relative to tumbler 31 swung downward, just can reach vertical sawing and treat cut
The purpose of part.Coordinate again refering to seeing Fig. 5, when this sawing unit 30 is positioned at duty, should
Sensing member 42 is away from this contact pressing piece 41, and this driver 34 can normal power supply.
As shown in Figure 6, when operator pulls this buck operating handle 23, and this buck 20 is made
When driving this sawing unit 30 to rotate relative to this base unit 10, this sawing list can be utilized
Unit 30 treats cut part and carries out the processing of oblique sawing.When operator operates this keeper 311
And this alignment pin 221, the tumbler 31 making this sawing unit 30 can be with this axis L for turning
The disorder of internal organs heart rotates predetermined angular relative to this buck 20, say, that shown in Fig. 1 to Fig. 6
State, if this sawing unit 30 is with this axis L, for center of rotation, to the left or right side rotates,
And make this alignment pin 221 be embedded in hole clipping 313 or the long circular arc on right side being positioned at centre respectively
In shape hole clipping 314 so that the end face of this saw blade 33 and this work surface 21 produce one and make a reservation for
During work angle, and this driver 34 is suspended at above the work surface 21 of this buck 20, energy
Reach the purpose (not shown) of this workpiece to be cut of sawing.
When sawing machine do not use and need to collect maybe need packaging transport time, operator can operate
This buck 20 drives this sawing unit 30 to turn towards the left side of Fig. 6 relative to this base unit 10
Dynamic 45 degree of angles.
Then, more as shown in Figures 7 and 8, operator operates this keeper 311 and this is fixed
Position pin 221, utilizes this alignment pin 221 to depart from hole clipping 313 or 314, and makes this tumbler 31
The effect that can rotate relative to this axle bed 22, can drive this sawing unit 30 entirety with this axle
Line L is that center of rotation rotates relative to this buck 20, until the end face convergence of this saw blade 33
During in this work surface 21 and substantially parallel to this work surface 21, this sawing unit 30 can be made
Operate into a folding state, utilize this alignment pin 221 to be embedded in hole clipping 312, make this saw
Cut unit 30 completes location, and this sawing unit 30 is when folding state, and this driver 34 becomes
Be bordering on this bottom surface 13 and to should posterior lateral margin 12 and be positioned on rear side of this buck 20 (in Fig. 7 not
Show), this tumbler 31 is also respectively positioned on rear side of this buck 20 with this support arm 32.
As shown in Figure 8, when this sawing unit 30 operates to folding state, this sawing unit
The tumbler 31 of 30 can drive detecting part 421 the touching by this contact pressing piece 41 of this sensing member 42
Splenium 412 touches, and just can cut off the power supply of this driver 34.
Therefore, the sawing machine of the present invention, utilize this sawing unit 30 to be folded into by duty
While folding state, the tumbler 31 of this sawing unit 30 can be made to drive this sensing member 42
Move relative to the rotation of this contact pressing piece 41, and reach to cut off the purpose of this driver 34 power supply, enter
And when guaranteeing folding state, operator will not cause danger because of misoperation the facts, energy
The safety of lifting operation.It is to say, utilize this foldable characteristic of sawing unit 30,
And utilize this sawing unit 30 of movable piece can not the phase of base unit 10 of moving part with this
To motion, whether judge dump, operator can be allowed visually just can judge that this drives
Whether the power supply of dynamic device 34 is cut off, can the safety of lifting operation and judgement ease.
It is noted that above-described embodiment is the safety device using contact, but
The most also contactless safety device (such as optical pickocff, not shown) can be used, should
Contactless safety device has one and produces relative to this buck 20 or this base unit 10
First sensing member of location and second sensing member being connected to this sawing unit 30 (are schemed not
Show), when this sawing unit 30 is positioned at duty, this second sensing member be away from this first
Sensing member, when this sawing unit 30 operates to folding state, this sawing unit 30 drives should
Second sensing member levels off to this first sensing member, can cut off the power supply of this driver 34, and should
After the installation position of safety device is also more than being limited in embodiment to be installed on this tumbler 31
Side, with in this rotating shaft 222, also can be installed on this sawing unit 30 and this base unit 10
Other relative position (not shown), are attained by identical safeguard protection purpose.
