This swing component 14 is to be articulated on this cross bar 121 and near its front end 121a, swing component 14 is cross bars 121 and make the beat of left and right directions relatively, the beat of this left and right directions can drive saw blade 30 and be inclination, because the non-the utility model emphasis of tilt adjustments of saw blade 30 will not be given unnecessary details in this.The swing component 14 of present embodiment generally is a ㄇ template, and is provided with the pivot ear 142 of parallel and downward extension in the both sides of its top board 141;

The ㄇ template of this spin ornament 16 for being constituted by two parallel side plates 161 and a top board 162 that connects this two side plate 161, it is by being run through this two pivots ear 142 and this two side plate 161 simultaneously by a pivot pin 11 and swing component 14 articulates and between this two pivots ear 142, each side plate 161 has a grooving 161a, as shown in Figure 4, wherein side plate 161 has more a hollow-out parts 161b, in addition, top board 162 outsides of spin ornament 16 are connected with this motor 28, and the output shaft 281 of motor 28 connects establishes this saw blade 30;

This screw rod 20 parallel cross bars 121 are provided with, the one end pass this swing component 14 and and guide block 18 be spirally connected and extend between this two side plate 161, make the two ends of guide block 18 be arranged in respectively among the grooving 161a of side plate 161, then affixed this handwheel 22 of the other end of screw rod 20;

This adaptor 24 is a L type bent plate, and its front end 241 is locked in swing component 14, and 242 of rear ends pass and are positioned at side plate 161 outsides with hollow-out parts 161b from this hollow-out parts 161b;

This first connector 26 is a microscler plate body, and it has one first side 261 and one second side 262, and this first side 261 articulates by being fixed point by a pin 27 with the rear end 242 of this adaptor 24, that is this pivoting point position is constant all the time;

This second connector 32 is combined by one first plate body 13 and one second plate body 15, please cooperate Fig. 5, shown in Figure 6, wherein:

This first plate body 13 is hubbed at the output shaft 281 of this motor 28, and its rear end is by being articulated by second side 262 of a pin 29 with this first connector 26, and front end then has been bent to form a flap 131, and this flap 131 has two perforation 131a;

This second plate body 15 is that one has been bent to form side plate 151, an intermediate plate 152 and a board 153, wherein this side plate 151 has two long slot bore 151a, two bolts 17 pass respectively behind this two long slot bores 151a and this two perforation 131a and corresponding nut 19 combinations, make second plate body 15 be connected with first plate body 13; This intermediate plate 152 has a locating hole 152a; And this board 153 has two fixing hole 153a.

This chopper 34 is for having the lamellar body of a blade 341, its positon of near bottom has two oblique elongated hole 34a, as Fig. 5, shown in Figure 7, two bolts 17 ' pass behind the two fixing hole 153a of this two elongated holes 34a and this board 153 and corresponding nut 19 ' combination again, make that this chopper 34 is affixed with this second plate body 15, and this blade 341 keeps a distance with these saw blade 30 peripheries, what another was carried is, as shown in Figure 9, after the structure of present embodiment can see through and unscrews bolt 17 and second plate body 15 is moved slightly again, multiple in screwing bolt 17 to reach fine setting chopper 34 positions, make chopper 34 and the excessive dislocation of saw blade 30 unlikely generations by this, in order to do the sawing operation that is beneficial to saw blade 30;

This support member 36 is for having the microscler plate body of an arc guide barrel 361, and it is fixed in cross bar 121 and is positioned at 121b place, nearly its rear end by wearing the top by a bolt 31 and screwing in cross bar 121;

This guiding piece 38 is a bolt in the present embodiment, its terminal jag 381 that forms, this jag 381 passes arc guide barrel 361 backs and corresponding nut 19 combinations of locating hole 152a and this support member 36 of this intermediate plate 152, and this guiding piece 38 makes this second connector 32 be produced the arching trajectory displacement.

More than be saw blade stable elevation structure 10 each member of present embodiment sawing machine and the explanation of relevant position thereof, then narration to the lifting control mode of its saw blade 30 in the back:

Fig. 3 discloses this saw blade 30 and is incorporated in this fixed platform 12 belows, and at this moment, the guide block 18 on the screw rod 18 is positioned near handwheel 22 1 sides, and 38 of this guiding pieces contact at arc guide barrel 361 root edges of this support member 36, make saw blade 30 can't continue controlled decline.

As shown in Figure 8, when rising this saw blade 30, the operator utilizes and rotates handwheel 22, can turn this screw rod 20 and order about guide block 18 along screw rod 20 toward saw blade 30 direction displacements, and then to promote with pivot pin 11 be that the spin ornament 16 of pivotal point is done swing, causes saw blade 30 to rise together with splitting 34 simultaneously; Mandatory declaration be, the structure 10 of present embodiment utilizes second connector 32 to connect motor 28 and support member 36 between two parties, and the arc guide barrel 361 that is limited by support member 36 with guiding piece 38 with the pass that limit method cooperates is, make saw blade 30 can not produce double swerve when rising, the saw blade that improves common structure according to this rocks the disappearance problem easily in lifting process.

Referring again to shown in Figure 10, saw blade stable elevation structure 40 for another preferred embodiment sawing machine of the utility model, be in the binding pass of first connector and swing component different with previous embodiment of this structure is, as shown in the figure, first side 421 of first connector 42 of this structure 40 is directly to be articulated in swing component 46 through a pin 44, its second side 422 is still and is articulated in second connector 48, be with, the side plate 52 of the spin ornament 50 in the present embodiment need not offered hollow-out parts, and the setting that can save adaptor, in order to do saving cost of manufacture.

The above only is a preferable possible embodiments of the present invention, changes so use the equivalent structure that specification of the present invention and claim do such as, ought to be included in the claim of the present invention.
