Be appreciated that before user's dismounting cutting mechanism 20, should at first backplate 29 be taken off from workbench 12, after the dismounting of accomplishing cutting mechanism 20, backplate 29 is being mounted to workbench 12, hinder disassembly process to prevent backplate 29.
Please consult Figure 11 and Figure 13 in the lump, also possess certain dust collection function, do not influence the inner dismounting passage that forms again, a base plate 108 can be set in the bottom surface of bearing 14 in order to make bearing 14.Base plate 108 can rotate to open or close dismounting inlet 106 with respect to bearing 14; Be that base plate 108 has the dismounting of closing inlet 106 and forms first POF of confined spaces with bearing 14 and workbench 12 and with respect to second POF of bearing 14 rotating opening dismounting inlet 106.When base plate 108 is in first POF, closed dismounting inlet 106, and owing to formed confined space, thereby be implemented in dust collection function; When base plate 108 is in second POF, opened dismounting inlet 106, this moment, the user can dismounting cutting mechanism 20, and also can clear up the dust in the bearing 14.
Between base plate 108 and bearing 14, be connected through rotating shaft; Thereby realize that base plate 108 can outwards rotate with respect to bearing 14, when needs cleaning dust is perhaps dismantled cutting mechanism 20, will spur base plate 108 and outwards rotate with respect to bearing 14; Inner dust just can be discharged outside the bearing 14; And opened dismounting inlet 106, this moment, base plate 108 was in said second POF, and the user can be through the dismounting 106 dismounting cutting mechanisms 20 that enter the mouth.
When making base plate 108 be in first POF, the position is more firm, can between pedestal 74 and base plate 108, position limiting structure be set, like buckle structure, or the angle position-limit mechanism of introducing like preamble.Certainly, also exist other technical scheme to realize limit function, at this as space is limited, no longer describe in detail, but, all should be covered by in the protection domain of the present invention as long as the function of its realization is same or similar with effect and the present invention of reaching.
Certainly; Dismounting passage in this embodiment is not limited to formed by the bottom of bearing 14; It also can be provided with supporting walls and window for the supporting walls of bearing 14; Be that said supporting walls is windowed and constituted said dismounting inlet, the user can window through said supporting walls said cutting mechanism 20 is taken out, and changes operations such as saw blade then.And also can combine the forms described in the above-mentioned embodiment, realize opening or closing of said dismounting inlet, at this as space is limited, no longer repeat to introduce.
What it may occur to persons skilled in the art that is that the bearing in the arbitrary embodiment of the present invention can adopt transparent material to process equally.Thereby the user can see the duty of cutting mechanism from different angle positions, no matter changes saw blade from that position, can both guarantee that saw blade clamps relieving mechanism and is in visual state, and it is safer that saw blade is changed.Certainly, the present invention's concrete embodiment of being not limited in this specification to be disclosed.Any variation of making based on the present invention and replacement are all within protection scope of the present invention.
