A physical coupling system for power tools may comprise an extension member protruding outwardly from a base of a power tool. The extension member may include a first end and a second end flexibly coupled to a base of a power tool. The system may also include a knob coupled to the first end of the extension member, wherein the knob has a greater profile than the extension member. The system may further include a slotted cup member configured to receive and secure the knob. The extension member may further include a flexible elastic member coupled thereto and extending from the second end. The system may further comprise an elongated member having a radius smaller than that of a hole through the base of the power tool, wherein the flexible elastic member is coupled thereto at a portion that is not an end of the elongated member.
