Referring now to FIG. 1B, a detailed example of the locking mechanism 120 is shown. In addition to the arm 130, the locking mechanism 120 includes a jaw 140 that is configured to be positioned against a portion of the enclosure to lock the system 100 into the enclosure. When the arm 130 is coupled to the rest of the locking mechanism 120, a transmission lever 150 transfers the rotation of the arm 130 to the jaw 140 in order to lock or unlock the jaw 140. The arm 130 may be selectively decoupled from the transmission lever 150, allowing the arm 130 to rotate about an arm pivot 155 in the transmission lever 150. The arm 130 includes a slider 160 that is configured to selectively decouple the arm 130 from the remainder of the locking mechanism 120. Transmission lever 150 may also include one or more detente as radially positioned features that allow arm 130 to occupy pre-set preferred angular positions.

Referring now to FIG. 2A, an example of a mechanism for decoupling the arm 130 from the rest of the locking mechanism 120 is shown in the coupled position. As shown in FIG. 2A, the arm 130 is coupled to the transmission lever 150, preventing the arm 130 from rotating about the arm pivot 155. With the arm 130 coupled to the transmission lever 150, the combination of those two elements rotates about an actuating pivot 210 in the locking mechanism 120. The jaw 140 also rotates about the actuating pivot 210 when pushed by the transmission lever 150.
