The transmission mechanism further having a linkage plate 131 driven by a cylinder lock 132. Located under the rotating block is a limit seat (140, fig.1). Preferably the radial slots are in the handle seat, rotating block and limit seat; in the slots are radially movable push block 117, unlocking block/pin 119 with lock bar/pin 120. The push block is spring biased outwardly against the rotating block. The aperture in the limit seat may align with an aperture in the rotating block.
