Abstract
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.

A tool holder assembly comprising:
- a main body;
- a tool;
- a cam lock;
- the main body comprising a first outer side, a proximal end, a distal end, and at least one raised section;
- the at least one raised section extending longitudinally outward from the proximal end towards the distal end;
- the at least one raised section comprising a first raised section;
