As seen in figs. 5-6, the near-end radial orientation of handle main body 11 is provided with square fixed block chamber 1113; Handle main body 11 is provided with caging bolt groove 1112 near distal end position; Handle main body distal end is provided with control power screw thread 1111; The central shaft of handle main body 11 is upwards provided with hollow cavity 1114.
As shown in figs 6-8, stay block fixed block 112 radial direction is provided with bracing wire fixed leg chamber 1123; Stay block fixed block axial inner is provided with wire chamber 1121 and draught line chamber 1122;
As shown in Figure 9, be provided with groove 1132 bottom bracing wire fixed leg 113, the centre of groove 1132 is provided with chamber 1131.
As shown in figs. 10-11, the push rod 12 of far-end comprises straight-bar 122 and control position plate 121; The two ends of control position plate 121 connect a straight-bar 122 respectively, and the central axis direction of push rod is provided with hollow cavity 123; The near-end circumferencial direction of straight-bar 122 is provided with groove 1222; Straight-bar proximal shaft is upwards provided with the U-lag 1221 mated with caging bolt 114; Control position plate 121 near near-end one side with push rod straight-bar 122 junction for cambered surface designs; The far-end connection pipe body 2 of push rod 12; Body 2 inside is provided with hollow cavity; The far-end of body is provided with tip electrode 21 and ring electrode 22.
Preferably, described controlled Handleset 1 processing mode is Shooting Technique; The tapering of described handle main body 11 is 1: 40; The material of main part of described controlled Handleset 1 adopts acetal resin.The material of described balance ring 116 and control power silica gel ring 117 is silicone rubber; Preferably, the material of described bracing wire fixed leg 113 is aluminium alloy; Preferred draught line is made up of NiTi super elastic marmen.
Operation principle of the present utility model is as follows:
Extend in the wire chamber 1121 of wire in stay block fixed block 112, lead proximal end is looped around on groove 1132 through the chamber 1131 in bracing wire fixed leg 113, be fixed on bracing wire fixed leg 113, then bracing wire fixed leg 113 inserted in stay block fixed block 112.Stay block fixed block 112 finally inserts in the fixed block chamber 1113 of handle main body 111.Draught line draught line chamber 1122 in extend, near-end is fixed on the head end of handle main body 111.
In the central shaft that the straight-bar 122 of push rod 12 inserts handle main body 11 hollow cavity 1114 upwards, balance ring 116 is fixed on groove 1222, and gets involved in the middle of hollow cavity 1114 inwall and groove 1222.The straight-bar 122 that control power nut 115 is enclosed within push rod 12 is fixed on control power screw thread 1111, and control power silica gel ring 117 is between control power nut 115 and control power screw thread 1111.Compensating roller by control power nut 115 of operator, control the power moved axially to push rod 12, the design advantage of balance ring 116 is that operator is when mobile putter 12, prevents straight-bar 122 from radially wobbling in hollow cavity 1114, plays the effect that balance is firm.
Caging bolt 114 passes handle 111 surface and ends in the U-lag 1221 of coupling on straight-bar 122, and push rod 12 pushes the axial distance that distance is U-lag 1221 back and forth, and convenient operation person controls push rod 12 and moves axially distance.
Wire passes the internal cavity of controlled Handleset 1 and body 2, and far-end ends at tip electrode 21 and ring electrode 11 place of body 2; Draught line passes the internal cavity of controlled Handleset 1 and body 2, and far-end ends at tip electrode 21 place of body 2.
Such as: the frictional force between handle main body 11 and push rod 12, by rotating control power nut 115, is adjusted to an optimum state by Producer, thus a best manipulation impression can be provided to operator.Operator in use, finger is placed on control power plate 121, apply certain thrust the inwall of push rod 12 along the hollow cavity 1114 of handle 111 is moved axially, because the near-end of draught line and far-end are stationary state, when pushing push rod 12, push rod 12 can drive body 2 to move, such draught line near-end is slowly entered in push rod 12 from pull-out in body 2, thus drive draught line far-end fixed position proximally to drop back, the distalmost end showing as body 2 is intuitively formed different bendings by slowly stretch bending, thus operator controls the demand that length that push rod 12 releases arrives the different bending of far-end for body 2 according to actual needs.
The above is only preferred implementation of the present utility model; be not limited to this utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
