Fig. 2 is the plan structure sketch map at clamp position among Fig. 1.

Among the figure: 1 fixed handle, 2 flexible handles, 3 back-moving springs, 4 steady pins, 5 tooth bars, 6 latches, 7 pull bars, 8 claw beams, 9 pull rod slot, 10 draw-bar seats, 11 clamps, 12 harmless folder teeth, 13 release grooves, 14 rotator, 15 flushing seats, 16 clamp seats, 17 camber circles, 18 connecting plates.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment:

Referring to Fig. 1～Fig. 2, present embodiment mainly comprises fixed handle 1, flexible handle 2, claw beam 8, pull bar 7, rotator 14, clamp seat 10 and clamp 11, be connected by steady pin 4 between fixed handle 1 and the flexible handle 2, be provided with back-moving spring 3 on fixed handle 1 and the flexible handle 2, one end of back-moving spring 3 is fixed on fixed handle 1 and the flexible handle 2, the other end compresses connection mutually, and has elasticity; The bottom of flexible handle 2 is provided with tooth bar 5, and the bottom of fixed handle 1 is provided with latch 6, and latch 6 snaps in tooth bar 5 and matches each other; One end of described claw beam 8 is inserted in rotator 14 and fixing, and the other end and clamp seat 16 are fixing, and rotator 14 is connected with fixed handle 1; Pull bar 7 passes claw beam 8 and rotator 14, and an end of pull bar 7 is installed on the flexible handle 2, and the other end is connected with clamp 11; Described clamp 11 has two, has harmless folder tooth 12 and release groove 13 on two clamps 11, and matches each other, and the middle part of clamp 11 is curved; Two clamps 11 are installed on the clamp seat 16, and the end of two clamps 11 is connected with pull bar 7 by connecting plate 18.

In the present embodiment, flexible handle 2 is provided with pull rod slot 9, and pull bar 7 is provided with draw-bar seat 10, and draw-bar seat 10 snaps in the pull rod slot 9.
