Replaceable blade mechanism
View Patent ↗The device is a tool holder capable of holding various types of tools. The device uses a cam lock mechanism designed to quickly attach and detach the tool from the tool holder. The cam lock cinches down on the shank of the tool, which virtually eliminates any play or movement during hard use. To replace the tool, the user deactivates the cam lock by pressing upward on the cam lever. In turn, the cam lobe rotates and slides out of a recessed portion of the shank. This unlocks the shank and allows the user to freely slide the tool out of the tool holder. To prevent the cam lock from accidentally unlocking during normal use, the device also incorporates a safety lock mechanism. The safety lock requires the user to first press and hold down a button next to the cam lock before disengaging the cam lock mechanism.
