Patent ID: 7758295

Claim:
A handling device comprising: a vertically disposed guide rod having a plurality of threads on its outer surface and being driven to rotate; a clamping arm being movably mounted on the guide rod and being able to move both in horizontal direction and vertical direction when being driven by the guide rod; a singular C-shaped housing being formed with a single gap, the single gap defining a single linearly directed longitudinal gap for the clamping arm to move therein in such a manner that the clamping arm partially extends out of the longitudinal gap of the housing, the C-shaped housing being able to rotate when driven by the clamping arm; a locking member being driven to selectively clamp and lock the C-shaped housing to stop it from rotating in such a manner that when the locking member releases the C-shaped housing, the clamping arm and the housing will rotate synchronously with the guide rod, and when the locking member locks the C-shaped housing, the guide rod is only able to drive the clamping arm to move up and down along the single linearly directed longitudinal gap of the C-shaped housing.
