Supplementary technology scheme of the present invention is as follows:
Preferably, described first fixture is the first adjustment screw, and described second fixture is the second adjustment screw, and the first adjustment screw is parallel with rotating shaft with the second adjustment screw, and traction fiber is wrapped in adjustment screw.
Preferably, described rotary part is coordinated by guide rail and guide pillar with grip.
Preferably, described grip has the guide rail with two sections of arc-shapeds, rotary part has the guide pillar coordinated with guide rail.
Preferably, described guide pillar is adjustment screw.
Preferably, rotary part has one along the passage of grip length direction, the width of this passage is arranged to, when rotary part around rotating shaft when rotating for ± 60 °, the both sides of passage can not exceed grip centrage.
Preferably, described rotary part comprises the driving upper cover and driving lower cover that are positioned at grip outside, and be positioned at the drive block of grip inside, several parts are installed together through the guide rail driven on the hole of upper cover, grip, hole on drive block and the hole that covers under driving by adjustment screw, between driving upper cover and grip, be provided with elastic seal ring, between driving lower cover and grip, be provided with elastic seal ring.
Preferably, driving upper cover or driving the both sides of lower cover to be fixed with regulating handle.
The invention has the beneficial effects as follows:
1, can manipulate two traction fiber routing motions, the far-end controlling conduit bends towards multiple directions, operates more flexible;
2, in some preferred embodiments, the design of grip and rotary part meets human engineering principle, and palm can hold the handle of rotary part completely, in operating process, finger, palm indefatigability, and in user operating process smooth operation;
3, in some preferred embodiments, grip and rotary part assembly relation rationally, make the structure of whole device more simple, reasonable, are easy to processing assembling.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
