A guide tube assembly for an industrial endoscope comprises a multiplicity of tube segments arranged to form therein a long guide bore. A hand actuator is connected to a proximal one of the tube segments. At least one pair of elongated members have their respective one ends fixedly secured to a distal one of the tube segments, and extend through communication bores formed in the remaining tube segments to the hand actuator. A resilient member is mounted on the hand actuator for resiliently pulling the elongated members to bias the tube segments so as to bring them into contact with each other.

A guide tube assembly for an industrial endoscope, comprising: a multiplicity of tube segments including a distal end tube segment and a proximal end tube segment and arranged to form therein a long guide bore, each of said tube segments including said proximal end tube segment having therein at least one pair of communication bores; a hand actuator connected to said proximal end tube segment, said hand actuator having one end thereof connected to said proximal end tube segment, said hand actuator having mounted thereon a rotatable drum movable along said hand actuator toward and away from said one end thereof, said pair of elongated members having their respective other ends connected to each other to form a loop trained around said drum, said resilient means biasing said drum away from said one end of said hand actuator, said hand actuator including a support pin mounted thereon so as to be slidable along said hand actuator, said drum being mounted on said support pin so as to be rotatable around an axis thereof, said resilient means comprising a coil spring having one end thereof connected to said support pin and the other end connected to said hand actuator; at least one pair of elongated members having their respective one ends fixedly secured to said distal end tube segment, said at least one pair of elongated members respectively extending through said at least one pair of communication bores in each of said tube segments including said proximal end tube segment, to said hand actuator; and resilient means mounted on said hand actuator for resiliently pulling said elongated members to bias said multiplicity of tube segments so as to bring them into contact with each other.
