<p><P>PROBLEM TO BE SOLVED: To provide a handle operation type working device of compact and simple structure, for smoothly performing work operation with a work unit at the tip of an operational pipe, by rocking operation of the handle by hand while holding a grip part. <P>SOLUTION: The handle operation type working device includes a support box 6 secured to a middle part between a grip part 3 and an operation pipe 1, a drive rotating shaft 7 which is supported in the direction orthogonal to the axial direction of the operation pipe by the support box, with a base end of a handle 5 attached through a one-way clutch, a sleeve capped over the drive rotating shaft, movable in axial direction but not movable in rotational direction, a pair of drive bevel gears arranged concentrically with the drive rotating shaft and constantly engaging with the driven bevel gear, with a one-way clutch attached on the inner peripheral surface, and a sleeve position switching device 25 for shifting the sleeve in the direction of the drive rotating shaft. Depending on the position of the sleeve, switching between forward and reverse rotations as well as locking is available. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
