Please shown in Figure 4 in conjunction with consulting again, be the exploded perspective view of the above-mentioned preferred embodiment of the present invention.Upper and lower bar 121, the 122 corresponding both ends of above-mentioned linkage unit 120 link respectively a saw blade swing limiting device of thread sawing 200, and this saw blade swing limiting device of thread sawing 200 has a swing arm that is articulated in this support 110 10, one saw blade grip slipper 20 that should swing arm 10, one are attached at the flexible connecting piece 30, one of 20 of this swing arm 10 and this saw blade grip slippers with these saw blade 300 lockings lock cell 40 and adjustment unit 50 that is installed on this support 10 at this saw blade grip slipper 20.
Above-mentioned swing arm 10, generally be microscler tabular, and have one be located in the middle of and be articulated in the articulated section 11 of this support 110, a linking part 12 and a swing part 13 that is arranged at this articulated section 11 and these linking part 12 1 sides that is arranged at these articulated section 11 1 sides, this linking part 12 with should on, lower beam 121,122 terminal parts are articulated, this swing part 13 is to be convexly equipped with on this, lower transverse tubule 111,112 outside, and has a junction 131, one is arranged at these junction 131 1 sides and is oval poroid sliding position 132 and a curved surface 133 that is arranged at the side edge, and the bearing of trend of this sliding position 132 is corresponding to the length direction of this swing arm 10.
Above-mentioned saw blade grip slipper 20 has a body 201, a pair of guide plate 202 that is articulated in 132 of this body 201 and this sliding positions;
This body 201 has that a pivot ear 203, one are arranged at these pivot ear 203 1 sides and to axle pivot portion 22 and a sticking department 23 that is arranged at these pivot portion 22 1 sides that should junction 131;
Described guide plate 202 has a pivot 204 that articulates with this pivot ear 203 and one and is the pin rod shape and is located in guide sliding part 21 in this sliding position 132.The circle footpath of this guide sliding part 21 is less than the length of this sliding position 132, and is and is articulated in slidably in this sliding position 132;
This sticking department 23 has a lockhole 231 and one and is convexly equipped with in this lockhole 231 1 sides and is the block position 232 of projection shape.
Above-mentioned flexible connecting piece 30, flexible connecting piece 30 at present embodiment is a chain, and having a first end that is articulated in this junction 131 31, a second end 32 and an interlude 33 of replacing on this curved surface 133 that is articulated in this pivot portion 22, this second end 32 can produce deflections with respect to this first end 31.
Above-mentioned lock cell 40, be with 300 lockings of this saw blade on this saw blade grip slipper 20, and have one with saw blade 300 be compressed on briquetting 41 on this block position 232 and one be locked in this lockhole 231 and this briquetting 41 of eccentric stopper with respect to these block position 232 convergences or away from operating parts 42.
Seeing also shown in Figure 7ly, is the cross-sectional schematic along Fig. 6 section line VII-VII.Above-mentioned adjustment unit 50 has an axostylus axostyle 52 that is installed in the upper lateral tube 111 of this support 10 and is articulated section 11 that inverted U-shaped bracing frame 51, one be connected these bracing frame 51 bottoms and pass top swing arm 10 and upper lateral tube 111, one and is arranged in this bracing frame 51 and supports the adjustment knob 53 that ends at this upper lateral tube 111, two guide block 54 and two locating pieces 55 that are set on this axostylus axostyle 52 and are positioned at described guide block 54 inboards that are set on this axostylus axostyle 52.Described guide block 54 drives this axostylus axostyle 52 and this swing arm 10 slides up and down along these upper lateral tube 111 generations, and described locating piece 55 limits this swing arm 10 and produces axial location, and operates the tension force that this adjustment knob 53 can be adjusted this saw blade 300.
Please consult Fig. 2, Fig. 3 and shown in Figure 5 again, Fig. 5 is the local enlarged diagram of the above-mentioned preferred embodiment of the present invention, illustrates that a swing arm is affected to lower swing by a linkage unit.Utilize upper and lower bar 121,122 ends of this linkage unit 120 to be articulated in the linking part 12 of described swing arm 10, then when this driver element 130 starts, this driver element 130 drives the extension bar 123 of this linkage unit 120 with eccentric manner, affect this upper boom 121 and lower beam 122 to move back and forth towards front and back in the opposite direction simultaneously, and the swing part 13 that can affect swing arm 10 is that the pivot center produces simultaneously up or simultaneously towards lower swing with articulated section 11.As shown in Figure 5, swing part 13 is when lower swing, and this flexible connecting piece 30, this saw blade grip slipper 20 and saw blade 300 move down.
Seeing also shown in Figure 6ly, is the operation chart of the above-mentioned preferred embodiment of the present invention, illustrates that this swing arm is subjected to this linkage unit to affect upwards swing.When swing part 13 was upwards swung, this junction 131 can affect this flexible connecting piece 30, and this flexible connecting piece 30 also affects this saw blade grip slipper 20 and saw blade 300 to move up.And in the operating process of swing arm 10 swings, the interlude 33 that utilizes this flexible connecting piece 30 is to replace on this curved surface 133 with local or most of length, produces skew and make this flexible connecting piece 30 be unlikely.
And, utilize this flexible connecting piece 30 to articulate with single-point mode and this saw blade grip slipper 20, and this guide sliding part 21 is the effect that is located in slippingly in this sliding position 132, when limiting this flexible connecting piece 30 and getting loose with respect to this swing arm 10 with this saw blade grip slipper 20 or this flexible connecting piece 30, because this guide plate 202 utilizes this guide sliding part 21 and this sliding position 132 to produce the relation that articulates, and can avoid this saw blade grip slipper 20 to produce significantly beat.
In addition, utilize the guide sliding part 21 of saw blade grip slipper 20 to be located in this sliding position 132, then provide 10 of this saw blade grip slipper 20 and this swing arms except utilizing flexible connecting piece 30 links, can increase a point of contact, when preventing these saw blade 300 breakdown, this saw blade 300 can be not significantly outwards bullet take off and injure the operator, be very suitable for practicality.
What deserves to be mentioned is that this flexible connecting piece 30 also can be cable wire (figure does not show), and can reach identical purpose and effect.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
