Well known to those skilled in the art, " the first inclined-plane " and " the second inclined-plane " also can be arranged to other form, so-called " the first inclined-plane " and " the second inclined-plane " thus purposes be to realize certain member and cause this member to change with respect to another member gap in the vertical with respect to moving axially of another member, therefore " the first inclined-plane " and " the second inclined-plane " also can arrange curved surface, thereby projection or other anyly can be realized the version that certain member causes this member to change with respect to another member gap in the vertical with respect to moving axially of another member.
Well known to those skilled in the art, fine setting operating parts 473 also can be arranged to other form, as button, folding rod etc., when the operating portion 411 of operating parts 410 adopts the form of button, button movement between the two positions, make the second inclined-plane 472 towards or away from the first inclined-plane 471 motion, thereby realize the adjusting in the gap between housing 200 and base plate 300; When operating parts 473 adopts the form of folding rod, after folding rod is opened, the arm of force is longer, user's labour-saving driving the second inclined-plane 472 motions between the two positions more, make the second inclined-plane 472 towards or away from the first inclined-plane 471 motion, thereby realize the adjusting in the gap between housing 200 and base plate 300.Certainly the motion of fine setting operating parts 473, make between the first inclined-plane and the second inclined-plane 472 as long as produce relative moving axially, likely the first inclined-plane is driven together with the second inclined-plane in certain embodiments, or only drive the first inclined-plane, but still produce relative moving axially between the first inclined-plane and the second inclined-plane.And adopting separately micro-adjusting mechanism cannot realize being held and being released of base plate, it is for the minor adjustments in the gap between housing and base plate.
Below the base plate 300 of describing in detail in the second embodiment by Figure 11-14 is released and clamped process.
First, adopt micro-adjusting mechanism 470 that the gap adjustment between base plate 300 and housing 200 is arrived in suitable scope, then, as shown in Figure 8, base plate 300 is positioned at clamped position, now operating parts 410 is positioned at the primary importance of clamping, the planar portions 310 of base plate 300 and the Surface Contact of workpiece to be processed are to provide the surperficial constant cutting angle with respect to workpiece to be processed, when needs carry out base plate angular adjustment, when the angle of base plate is replaced with to the dotted line position in Figure 14, operating parts 410 is moved to the second place as shown in Figure 9 from primary importance as shown in Figure 8, now, base plate 300 is positioned at off-position, its angle with respect to housing can be adjusted to the dotted line position in Figure 14, when operating parts 410 moves to the second place from primary importance, operating parts 410 drives the first cam surface 430 rotations, make the first cam surface 430 and the second cam surface 440 depart from engagement, make to produce enough gaps with movable base plate 300 between base plate 300 and housing 200.In primary importance, securing member 420 is fixed on base plate 300 on housing 200, engagement by the first cam surface 430 and the second cam surface 440 makes to there is no gap between base plate 60 and housing 20, that is to say, base plate 300 is clamped when intermeshing at the first cam surface 430 and the second cam surface 440, as shown in Figure 12 and Figure 13, a side in the arcuation portion 320 of base plate 300 is provided with clamping plate 450, opposite side in arcuation portion 320 is provided with operating parts 410, and base plate 300 and housing 200 are clamped between operating parts 410 and clamping plate 450.
