Described spiral shell spare 230 and auxiliary member 240 have a relative axial through hole 231,241 respectively in the center, described spiral shell spare 230 is one to have the cylinder of biend, wherein an end face and auxiliary member 240 join, in contrast to then having a receiving room 232 (with reference to Fig. 5) that is connected with through hole 231 with a end face that auxiliary member 240 joins.
Described holding firmware 250 has first end 251 and second end 252, and first end 251 is the different cylinder of external diameter with second end 252, and on the cylinder wall of first end 251, form a groove 2511, described first end 251 be sheathed described elastic component 260 and pass spiral shell spare 230 and the through hole of auxiliary member 240 231,241 after, be combined on the groove 2511 of holding firmware 250 with fastener 270 again, holding firmware 250 and elastic component 260 can be moved in receiving room 232 and can not come off.
And described protecting cover 300 has a holding section 310, described holding section 310 is to engage with groove 222 formed openings 280, described holding section 310 also is provided with a locating hole 311, described locating hole 311 internal diameters are slightly larger than the external diameter of holding firmware 250 second ends 252, when the holding section 310 of protecting cover 300 is engaged with opening 280, second end 252 of holding firmware 250 can engage with the locating hole 311 of protecting cover 300, protecting cover 300 can't be separated with fixture 200, and the profile of described protecting cover 300 and the visual user's of thickness demand and do replacing.
Show that to Fig. 5 protecting cover 300 is fixed on the relative position figure between first holder 210 and second holder 220 with reference to Fig. 3.
With reference to Fig. 5, when protecting cover 300 is fixed between first holder 210 and second holder 220, described holding firmware 250 is subjected to the active force of elastic component 260 and engages with the locating hole 311 of protecting cover 300, protecting cover 300 is limited between first holder 210 and second holder 220, control moving of spiral shell spare 230 to reverse auxiliary member 240, make protecting cover 300 quilts clamping tightly between the spiral shell spare 230 and second holder 220.
With reference to Fig. 6 and Fig. 7, when user's desire is changed protecting cover 300, can reverse auxiliary member 240 earlier outwards moves spiral shell spare 230, and then make protecting cover 300 loosening, again auxiliary member 240 is outwards spurred, holding firmware 250 is no longer engaged with the locating hole 311 of protecting cover 300, and this moment just can be with protecting cover 300 by taking out between first holder 210 and second holder 220.
With reference to Fig. 8, described fixture 200 also can utilize described auxiliary member 240 to control gap between the spiral shell spare 230 and second holder 220, therefore when the user changes the protecting cover 300 of different-thickness, the user only need be gone to reverse and drawing auxiliary member 240 by single direction, just can reach the purpose of quick replacing protecting cover 300.
With reference to Fig. 9 and Fig. 3, described lowering or hoisting gear 400 includes a sector gear 410, one screw rod 420 and a rotating disk 430, wherein said sector gear 410 is provided with a pivoted hole 411 and a protuberance 413, described pivoted hole 411 positions are near the center of circle of sector gear 410, described pivoted hole 411 is to utilize a spiral shell spare 412 sector gear 410 to be articulated on the support body 120 of sawing unit 100,413 of described protuberances are formed with a bolt apertures 4131, described bolt apertures 4131 also utilizes a spiral shell spare 414 to connect sector gear 410 and drive unit 110, drive unit 110 can be slided in chute 121 with respect to the pivot of sector gear 410, described screw rod 420 is to be hubbed on the through hole 122 and to have two ends, wherein an end and sector gear 410 join and have an external screw thread 421, described external screw thread 421 is to be meshed with sector gear 410 and can to relatively rotate, then affixed with described rotating disk 430 in contrast to an end that joins with sector gear 410.
The user can utilize rotation rotating disk 430 to make screw rod 420 along with rotation, and then to make sector gear 410 be that central point pivots with pivoted hole 411, when sector gear 410 to support body 120 is inboard when pivoting, the position of protuberance 413 can be along with rising, because drive unit 110 is the protuberances 413 that are fixed on sector gear 410, therefore, drive unit 110 also can move to chute 121 tops along with the rising of protuberance 413, simultaneously, the position of saw blade 900 is also along with drive unit 110 rises.
With reference to Figure 11 and Figure 12, when sector gear 410 when support body 120 outsides pivot, the position of protuberance 413 then can be along with decline, because drive unit 110 is the protuberances 413 that are fixed on sector gear 410, therefore, drive unit 110 also can move to chute 121 belows along with the decline of protuberance 413, and simultaneously, the position of saw blade 900 is also along with drive unit 110 descends.
Can summarize the present invention with regard to the above and have following advantage:
1. the present invention has the saw cutting device of protection structure, and the design of wherein said fixture can allow the user only need to go to reverse and the drawing auxiliary member just can be fast and change easily protecting cover from single direction.
2. the present invention has the saw cutting device of protection structure; the relative altitude of wherein said lowering or hoisting gear capable of regulating saw blade in saw cutting device; when saw cutting device during at idle state; also can be received into saw blade in the saw cutting device fully; therefore; described lowering or hoisting gear can increase outside user's the convenience on the one hand, but on the other hand property increase user's security.
More than explanation is for the purpose of the present invention just illustrative; and nonrestrictive, those of ordinary skills understand, in the situation that does not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but all will fall within protection scope of the present invention.
