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. 8, this utility model embodiment fixed handle 1, flexible handle 2, claw beam 3, rotary wheel device 4, binding clip seat 5, clamp 6, adapter sleeve 7, pull bar 8, pull bar joint chair 9, bending connector 10, curved moving runner 11, stone dead wire 12, forward nut 13, forward swivel nut 14, reverse nut 15, reverse swivel nut 16, bending pull bar 17, No. two bending pull bars 18.

Fixed handle 1 and flexible handle 2 are rotationally connected.

Rotary wheel device 4 is connected with claw beam 3 with fixed handle 1 respectively, and rotary wheel device 4 can drive claw beam 3 and rotate, and 3 drive clamps of claw beam 6 rotate.

Clamp 6 is connected on the binding clip seat 5.

Stone dead wire 12 is connected between pull bar 8 and the pull bar joint chair 9, makes pull bar 8 be connected with pull bar joint chair 9.Pull bar 8 one ends are connected with flexible handle 2, and pull bar joint chair 9 is rotationally connected with clamp 6.

Claw beam 3 one ends are connected on the fixed handle 1.Bending connector 10 is connected between binding clip seat 5 and the claw beam 3, makes binding clip seat 5 be connected with claw beam 3.Bending connector 10 is provided with and rolls seat 21 and slot rolling 22, and has bending threaded hole of steel 23 and tie rod hole 24.Two bending threaded hole of steel 23 are inserted in a bending pull bar 17 and No. two bending pull bars 18 respectively, tie rod hole 24 is inserted in stone dead wire 12, be inserted in Psychotria rubra (Lour.)
