Fig. 2 is the structure for amplifying sketch map (when closing up) at A place among Fig. 1.

Fig. 3 is the structural representation of looking up of Fig. 2.

Among the figure: 1 fixed handle, 2 flexible handles, 3 back-moving springs, 4 steady pins, 5 rest pads, 6 pull rod slot, 7 pull bars, 8 draw-bar seats, 9 claw beams, 10 active clamps, 11 are poor, the 13 active clamp steady pins of clamp, 12 clamps, 14 active clamp connecting pins, 15 rotator, 16 bearing holder (housing, cover)s, 17 bearing blocks, 18 fixture blocks, 19 bearings, 20 set bolts, 21 irrigators fixedly.

The specific embodiment

Referring to Fig. 1-Fig. 3, this utility model is mainly by fixed handle 1, flexible handle 2, back-moving spring 3, rest pad 5, pull bar 7, draw-bar seat 8, claw beam 9, active clamp 10, fixedly clamp 11, rotator 15, bearing holder (housing, cover) 16, bearing block 17, fixture block 18 and irrigator 21 are formed.

Fixed handle 1 fuses with rest pad 5, and fixed handle 1 is connected with flexible handle 2 usefulness set bolts 20 and can rotates; Article two, back-moving spring 3 compresses mutually, is fixed on fixed handle 1 and the flexible handle 2 with steady pin 4 respectively, and has elasticity; Flexible handle 2 is one with pull rod slot 6.

Rotator 15 is fixed on the bearing block 17, and claw beam 9 penetrates rotator 15 and is fixed on the bearing block 17, and two bearings 19 are inserted in bearing block 17, and bearing holder (housing, cover) 16 and bearing block 17 tighten and be fixed on the rest pad 5 mutually; It is fixing that one end of fixture block 18 snaps in bearing holder (housing, cover) 16, and the other end is fixed on the rest pad 5; Irrigator 21 is fixed on the rotator 15.

Fixedly clamp 11 and active clamp 10 are provided with clamp poor 12, the binding clip of active clamp 10 and fixedly clamp 11 coupling coincide, the pincers tail of active clamp 10 is fixed on fixedly on the clamp 11 with active clamp steady pin 13 on one side and can rotates, and another side is fixed on the pull bar 7 with active clamp connecting pin 14 and can rotates.

One end of pull bar 7 is connected with active clamp 10, and the other end is connected with draw-bar seat 8; Pull bar 7 penetrates claw beam 9, and passes rotator 15, bearing block 17 and rest pad 5, and draw-bar seat 8 is inserted in pull rod slot 6 and coincide fixing.Fixed handle 1 and fixed handle 2 as long as at this moment hold with a firm grip, pull rod slot 6 pulling pull bars 7, pull bar 7 pulling active clamps 10, active clamp 10 and fixedly clamp 11 coincide sting tight; Decontrol fixed handle 1 and fixed handle 2, under the effect of two back-moving springs 3, active clamp 10 and fixedly clamp 11 reset.
