Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Refering to fig. 1~Fig. 4, a kind of pipe cutter convenient for allowing blade replacement of the utility model, comprising: knife shell 1, is fixed blade 2
Boss 3, fixed pin 5, fixing buckle 7, promotes and detains 8 and flexible handle 9 torsional spring 4, and in the present embodiment, knife shell 1 divides for left knife shell and the right side
Knife shell, wherein the inside of right knife shell is equipped with a cylinder boss and a positioning pin, it is convex that the both ends of torsional spring 4 are respectively fitted over this cylinder
On platform and positioning pin, blade 2 is fixed in knife shell by positioning bolt 12, which can axially rotate around positioning bolt 12,
Blade 2 is equipped with card slot and latch, and the hook projected upwards among torsional spring 4 is hooked on the card slot of the blade 2, in the pipe cutter
Blade 2 can be ejected into certain angle by the elastic force of torsional spring 4 when opening, and the tail portion of the blade 2 is equipped with rack gear, and fixing lug boss 3 is arranged
On right knife shell, the surface of the fixing lug boss 3 is equipped with trapezoidal slope surface, and fixed pin 5 is fixed on left knife shell, among the fixed pin 5
To play the role of fixed torsional spring 4, torsional spring 4 is prevented to be detached from for being riveted with the positioning pin on right knife shell equipped with circular hole, fixed
It is equipped with circular through hole on boss 3 and fixing buckle 7, tension spring 6 is equipped between two circular through holes, the tension spring 6 is for limiting activity
The position of handle 9 and the elastic force pulled back is provided for fixing buckle 7；Flexible handle 9 is hinged on knife shell 1, corresponding activity on knife shell 1
Limit block face 13 is equipped at handle 9, one end of flexible handle 9 can be blocked by the limit block face 13 when pipe cutter opening state,
The angle for avoiding flexible handle 9 from opening is excessive to cause tension spring 6 to damage, and fixing buckle 7 and propulsion button 8 are hinged in flexible handle 9,
The surface of the flexible handle 9 is equipped with handle sheath 10, and the tail portion of flexible handle 9 is hinged with handle lock 11.
