When blade was locked, the blade pintle hook lock was gone into first through hole;
During the blade release, the blade lock leaves first through hole.
Preferably, also comprise knife rest, said blade is arranged in the blade storage tank of said knife rest.
Preferably, also comprise blade cover, said blade cover covers on the said blade; And have second through hole on the said blade cover, said second through hole is corresponding with said first through hole; And said second through hole and said blade lock are suitable.
Preferably, said blade lock is a screw; The inwall of second through hole is provided with the screw thread with said screw engagement;
When blade was locked, screw passed second through hole and snaps in first through hole;
During the blade release, screw through and the second through hole internal thread between engagement, leave first through hole.
Preferably, have cross recess on the nut of said screw.
Preferably, have flat recess on the nut of said screw.
Preferably, said blade cover is fixed on the said knife rest.
Preferably, the end of said blade lock has a magnet, and said magnet and said first through hole are adaptive; When blade was locked, the blade lock passed second through hole, and first through hole is gone in its terminal adhesive; During the blade release, the end of blade lock leaves first through hole.
Preferably, said blade lock front end is provided with one handle.
Compared with prior art, the utility model is simple in structure, cost is low, and it is very convenient to change blade.
Description of drawings
Fig. 1 is the exploded view of the utility model first embodiment;
Structural representation during Fig. 2 correspondence the utility model first embodiment insert retention;
Structural representation during the first embodiment release of Fig. 3 correspondence the utility model.
The specific embodiment
A kind of emergent blade is changed structure fast, comprises blade and blade lock; Said blade is provided with first through hole, and said blade lock is corresponding with said through hole.
When blade was locked, the blade pintle hook lock was gone into first through hole;
During the blade release, the blade lock leaves first through hole.
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explanation.
Fig. 1 is the exploded view of the utility model first embodiment.Emergent cutter shown in Figure 1 is changed structure applications fast on cutting knife, is merely for example, and it also can be applicable to it not made qualification here on other cutter.
The emergent cutter of first embodiment is changed structure fast and is comprised blade 1, blade lock 4, knife rest 2 and blade cover 3.Blade 1 is arranged in the blade storage tank on the knife rest 2; Blade cover 3 covers on the blade 1, and is fixed on the knife rest 2 through four Screws 5.
It is corresponding with first through hole 11 to have second through hole, 31, the second through holes 31 on the blade cover 3; And it is 4 suitable that second through hole 31 and blade are locked.
In first embodiment, blade lock 4 is a screw; The inwall of second through hole 31 is provided with the screw thread with said screw engagement.
When blade 1 was locked, blade lock 4 passed second through hole 31 and snaps in first through hole 11.
During blade 1 release, blade lock 4 through and second through hole, 31 internal threads between engagement, leave first through hole 11, at this moment, the user can take out blade easily.
For the convenience of the users, can on nut, have the groove that is fit to screwdriver work as the screw of blade lock 4.Among first embodiment, have cross recess on the nut, convenience is tightened with Phillips screwdriver or is unscrewed blade and lock 4.
When concrete the use, also can have flat recess on the nut, convenience is tightened with straight screwdriver or is unscrewed blade and lock 4.The utility model is not made qualification to this.
Structural representation when Fig. 2 and Fig. 3 corresponding first embodiment insert retention of difference and release.
Second embodiment of the utility model, emergent cutter change structure fast and comprise blade, blade lock, knife rest and blade cover.Blade is arranged in the blade storage tank on the knife rest; Blade cover covers on the blade, and is fixed on the knife rest.
