The utility model is further arranged to：The shell includes the diameter lower casing consistent with cylinder head portions and diameter is small
In the upper casing of lower casing, the upper casing is axially set in end face of the lower casing away from cylinder, and the telescopic chute is located at upper casing, the cutting
Block is arranged at lower casing and abutted against with side of the cutter away from piston rod.
By using above-mentioned technical proposal, shell is divided into upper casing and lower casing, and upper casing has less diameter, reduces
Break wire device improves space availability ratio to the occupancy in space.
The utility model is further arranged to：The upper end of the cutting cube is additionally provided with the cutting abutted against with cutter
Sword.
By using above-mentioned technical proposal, cut compared between blunt cutting cube and cutter by extruding, it is sharp
Extruding between cutting edge and cutter is more beneficial for cutting off sewing thread.
In summary, the utility model has the advantages that：
1. it is more prone to cut off sewing thread；
2. cutting process is more stable；
3. reduce space hold.
