See also Figure 11 and Figure 12, in order to save the time of dismounting cutting mechanism 20, bring advantage to the user, cutting mechanism 20 can be arranged on the installed surface 24 of workbench 12 by quick-disassembly structure, as the both sides of the installed surface 24 relative openings 28 at workbench 12, two stopper slots 107 that protrude installed surface 24 and be oppositely arranged are set respectively, and the bearing of trend of stopper slot 107 is parallel with the cut direction of saw blade 30.Cutting mechanism 20 is provided with limiting plate 109, and slides along stopper slot 107 by limiting plate 109, realizes dismounting cutting mechanism 20.So arrange, the dismounting that realizes cutting mechanism 20 is very convenient, has brought facility to user.Further, in order to make cutting mechanism 20 when the cut workpiece, the position of limiting plate 109 can not change with respect to the position of stopper slot 107, can make stopper slot 107 have dismounting end 111 and positive stop end 113, and limiting plate 109 is packed into stopper slot 107 or skidded off stopper slot 107 by dismounting end 111.And positive stop end 113 employing sealings arrange and have the stop surface of backstop limiting plate 109, and the bearing of trend of described stop surface is vertical with described cut direction.After limiting plate 109 is fit into stopper slot 107, can be against on the stop surface of positive stop end 113, thereby realize the spacing reliable and stable of cutting mechanism 20.The length of stopper slot 107 is less than the width of opening 28 with respect to cut direction, so that when cutting mechanism 20 is mounted to workbench 12, first saw blade is stretched out from opening 28, and then limiting plate 109 is inserted in stopper slot 107.Because in the time of dismounting cutting mechanism 20, in most cases in order to change saw blade, so the behavior of most dismounting cutting mechanisms 20 is to carry out in the situation that it is provided with saw blade, be provided with in order to realize cutting mechanism 20 in the situation of saw blade and realize overall quick detach, make the length of stopper slot 107 be less than the described width of opening 28, now just can reserve certain space, make saw blade 30 can stretch out opening, and then slide into positive stop end 113 by limiting plate 109 with respect to stopper slot 107, now saw blade is in the interior movement of opening 28, can do not stopped by other objects, therefore realize cutting mechanism 20 and be quick mounting to workbench 12.
Be appreciated that before user's dismounting cutting mechanism 20, should first backplate 29 be taken off from workbench 12, after completing the dismounting of cutting mechanism 20, backplate 29 is being mounted to workbench 12, to prevent that backplate 29 from hindering disassembly process.
See also Figure 11 and Figure 13, in order to make bearing 14 also possess certain dust collection function, do not affect again the inner dismounting passage that forms, a base plate 108 can be set in the bottom surface of bearing 14.Base plate 108 can rotate to open or close dismounting entrance 106 with respect to bearing 14, be that base plate 108 has and closes dismounting entrance 106 and form the first POF of confined space with bearing 14 and workbench 12, and with respect to the second POF of bearing 14 rotating opening dismounting entrances 106.When base plate 108 is during in the first POF, close dismounting entrance 106, and owing to having formed confined space, thereby realize at dust collection function; When base plate 108 is during in the second POF, open dismounting entrance 106, now user can dismounting cutting mechanism 20, and also can clear up the dust in bearing 14.
Between base plate 108 and bearing 14, be connected by rotating shaft, thereby realizing base plate 108 can outwards rotate with respect to bearing 14, in the time that needs are cleared up dust or dismounting cutting mechanism 20, to pull base plate 108 outwards to rotate with respect to bearing 14, inner dust just can be discharged outside bearing 14, and opened dismounting entrance 106, now base plate 108 is in described the second POF, and user can be by dismounting entrance 106 dismounting cutting mechanisms 20.
In order to make base plate 108 when the first POF, position is more firm, can between pedestal 74 and base plate 108, position limiting structure be set, as buckle structure, or as the angle position-limit mechanism introduced above.Certainly, also exist other technical scheme to realize limit function, at this as space is limited, no longer describe in detail, but as long as the function of its realization is same or similar with effect and the present invention of reaching, all should be covered by protection domain of the present invention.
Certainly, dismounting passage in present embodiment is not limited to be formed by the bottom of bearing 14, it also can be windowed for be provided with supporting walls on the supporting walls of bearing 14, be that described supporting walls is windowed and formed described dismounting entrance, user can be windowed described cutting mechanism 20 is taken out by described supporting walls, then changes the operations such as saw blade.And also can, in conjunction with the forms of describing in above-mentioned embodiment, realize opening or closing of described dismounting entrance, at this as space is limited, no longer repeat to introduce.
It may occur to persons skilled in the art that, the bearing in the arbitrary embodiment of the present invention can adopt transparent material to make equally.Thereby user can see from different angle positions the duty of cutting mechanism, no matter change saw blade from that position, can both ensure that saw blade clamps relieving mechanism in visual state, changes saw blade safer.Certainly, the present invention is not limited in the concrete embodiment disclosing in this description.Any variation of making based on the present invention and replacement are all within protection scope of the present invention.
