Pivotable connector for manipulator

摘要

A connector includes a pivot portion (10), a sleeve (40) and a connect portion (60). The pivot portion includes a body (12) and a head (14). The body defines two channels (16), and two through holes (18) in respective communication with the channels. The head defines two outlets (20) and two bores (22). Each bore is in communication with a corresponding through hole and outlet. The sleeve surrounds the body and defines a plurality of inlets (42) in communication with the corresponding channels. The connect portion is attached under the pivot portion and engaged with a pivot axle of a manipulator. The sleeve is fixedly attached to a fixed part of the manipulator. When the combined pivot portion and the connect portion is pivoted by action of the pivot axle, the sleeve remains stationary. Pipes connected to the inlets are thereby prevented from being twisted or distorted by the manipulator.
