Instead, the staff adjust the angle of the plate by themselves, which is easy to cause errors and lead to waste of plate resources. In the process of cutting the plate, the plate has a great force on the saw blade, which is easy to cause harm to the staff. Moreover, in actual use, the height of the saw blade cannot be adjusted, which is very inconvenient when it is necessary to cut the plate at different depths.

[0004] Therefore, a dust-free saw with high stability and adjustable angle is needed to solve the problems mentioned in the above background technology. Utility Model Content
