A connection member connects the discharge member with the longitudinal passage and the cut created rear of the longitudinal passage.
Claims18
A circular saw blade guard assembly comprising:
- a blade guard and a blade guard receiver;
- said blade guard comprising a cover for covering at least a portion of both a first side and a second side of a saw blade of the circular saw, the blade guard further comprising a first locking formation on an outer surface of said cover, wherein the first locking formation is located at an end portion of the cover of the blade guard and extends over portions of the cover that correlate to both the first side and the second side of the saw blade, the first locking formation including an attachment pattern facing outward from the first side and the second side of the saw blade;
- said blade guard receiver comprising a housing which defines a substantially u-shaped opening and a second locking formation on an inner surface of said substantially u-shaped opening, the second locking formation defining a cooperating formation that corresponds to the attachment pattern, the cooperating formation defining protrusions extending substantially toward the first side and the second side of the saw blade;
- wherein at least part of said blade guard, including said first locking formation, can be inserted into said substantially u-shaped opening, and wherein said first and second locking formations are arranged to cooperate with one another to lock the blade guard to the blade guard receiver when the blade guard is inserted into the blade guard receiver.
