Limit base described in the utility model is eight.

This utility model reasonable in design, structural design scissors bit cutting edge is curved, can rotate by 360 degree, and result of use is good, convenient and safe.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment.

The specific embodiment

Referring to Fig. 1, this utility model hook is cut and is comprised movable scissors 1, fixed blade 2, blade 3, link pin 4, clamp connecting pin 5, binding clip seat 6, claw beam 7, insulation sleeve 8, pincers seat 9, runner 10, rotaring wheeling sleeve 11, stage clip 12, ball 13, fixed cover 14, limit base 15, rotating shaft 16, nut 17, draw-bar seat 18, pull rod slot 19, connecting bolt 20, fixed handle 21, flexible handle 22, pull bar connecting axle 23, pull bar 24, flexible handle 22 has pull rod slot 19, and fixed handle 21 and flexible handle 22 usefulness connecting bolts 20 are connected and fixed and can rotate; Pull bar connecting axle 23 is fixing with draw-bar seat 18 welding, and pull bar connecting axle 23 is inserted in fixed handle 21, and draw-bar seat 18 snaps in 19 identical connections of pull rod slot just; Fixed cover 14 has (eight) limit base 15, and rotating shaft 16 is inserted in fixed cover 14 and can be rotated, and rotating shaft 16 1 ends are tightened with nut 17; It is fixing that fixed cover 14 snaps in fixed handle 21; Stage clip 12 and ball 13 are installed in the rotaring wheeling sleeve 11, and the other end that rotaring wheeling sleeve 11 is inserted in rotating shaft 16 is tightened fixing, and ball 13 is stuck in limit base 15 just and coincide under the effect of stage clip 12, and rotaring wheeling sleeve 11 has eight orientations in rotation.

Movable scissors 1 and fixed blade 2 respectively have blade 3, and shears clamps two blades 3 and coincide, and fixed blade 2 is fixing with 6 welding of binding clip seat, and fixed blade 2 is fixedlyed connected with claw beam 7; One side of movable scissors 1 is fixed on the binding clip seat 6 and can rotates with clamp connecting pin 5, and another side is fixed on the pull bar 24 and can rotates with link pin 4; It is fixing that insulation sleeve 8 is inserted in claw beam 7, pincers seat 9 is inserted in runner 10 to be tightened fixingly, and pincers seat 9 and runner 10 are inserted in insulation sleeve 8, and pincers seat 9 is fixing with insulation sleeve 8 gummeds, pull bar 24 is inserted in claw beam 7 back stays 24, and to be inserted in pull bar connecting axle 23 gummed fixing, and runner 10 is inserted in rotaring wheeling sleeve 11 to be tightened fixing.
