The saw blade protective cover of plate shield composition closing.
The further preferred scheme of the invention, described movable shield are provided with what is be engaged with fixed shield end face
Limited step.
After using said structure, have the following advantages compared with the prior art and effect:One is due to unblock button and driving lever
Linkage, driving lever are linked with self-locking limit pin again, and when unblock button is moved left and right, unblock button can pass through notch or push rod band
Dynamic driving lever is turned in the same direction around hinge, and driving lever drives self-locking limit pin axially inwardly to move, and departs from self-locking limit pin right
Movable shield it is spacing, so as to reach movable shield unblock purpose, simple to operation, right-hand man can use, also significantly
Facilitate left handed user.Two be saw blade stop cutting when, bearing pin is moved proximally to along base plate guide groove from distal end, and bearing pin is being moved
While drive movable shield and movable auxiliary shield to open, be automatically composed the saw bit protective of closing with base plate shield and fixation shield
Cover；When saw blade cuts, bearing pin is proximally moved to distal end along base plate guide groove, bearing pin drive while mobile movable shield and
Movable auxiliary shield bounces back into fixed shield, is gradually opened protective cover, it is ensured that saw blade is synchronous with saw blade protective cover when cutting to be opened,
It is simple to operation, it is safe and reliable, can effectively prevent infringement of the saw blade to the person and property.
