Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and the cutter that has novel blade handler lockable blade is provided, thereby realizes changing easily blade.
The technical scheme of the utility model multipurpose cutter is: a kind of band can be locked the cutter of blade side chain, comprise handle of a knife, be articulated in the blade on the handle of a knife, it is characterized in that: described blade front end is provided with the slit that blade is installed, and the blade back is provided with the handler that flexibly connects this blade.
The location grab that described handler comprises flexible substrates and is fixedly connected on this substrate front end, the flexible substrates rear end is fixed on the blade; Described blade is provided with the draw-in groove that matches with this location grab.
As further improvement of the utility model, described flexible substrates is provided with the projection of being convenient to push; Be provided with clearance position with the corresponding position of this projection on the described blade.
Described flexible substrates is made with location grab one, or flexible substrates and location grab are made separately respectively again and being connected as one.
Described projection is made with location grab one, or projection and location grab are made separately respectively again and being connected as one.
Be connected to welding or riveted joint or tight fit between described flexible substrates, location grab, the projection connect.
Described flexible substrates rear end is connected be connected to welding or riveted joint or tight fit between the blade.
Especially, the front end of described blade is connected with the blade cover that entangles the blade exposed parts.
Described projection can be made rectangle or circular arc or oval or bent limit shape.
Further improve as of the present utility model, described handle of a knife is provided with the shell fragment of fastening blade when cutter uses, and the rear end of shell fragment is fixed on the handle of a knife, and the front end overhead is at the terminal surface of blade.
The beneficial effects of the utility model are, the side chain of a band lockable blade is set by the back at blade, be the elasticity handler of changing blade specifically, the back of blade is provided with the U-shaped draw-in groove of being convenient to loading, unloading, the elasticity handler at this draw-in groove and blade back cooperatively interacts, pin the projection of elasticity handler front end, just blade can be taken out from blade, the practicality and the convenience of this multipurpose cutter replacing blade have been strengthened greatly, after the cutting edge wearing and tearing or destruction of blade, the blade that can more renew easily and the blade of different cutting edges.Particularly the exposed parts at blade is provided with the blade cover, has increased the security of cutter.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the front view of the utility model multipurpose cutter;
Fig. 2 removes the vertical view of blade cover for Fig. 1;
Fig. 3 is Fig. 2 cutaway view;
Fig. 4 is the front view of another planform blade among Fig. 3;
Fig. 5 is the front view of another embodiment of the utility model multipurpose cutter.
The specific embodiment
Embodiment 1:
Can lock the cutter of blade side chain as accompanying drawing 1, Fig. 2, the utility model band shown in Figure 3, comprise handle of a knife 1, be articulated in blade 2 on the handle of a knife 1 by bearing pin 13, blade 2 front ends are provided with the slit 5 that blade 3 is installed, and blade 2 backs are provided with the handler 4 that flexibly connects this blade 3.Handle of a knife 1 by about two handle of a knife sheets 11 be formed by connecting by 3 pins 10, handler 4 is by flexible substrate 42 and the location grab 41 that is located at these substrate 42 front ends and substrate 42 one, and flexible substrates 42 can be to make separately respectively with location grab 41, connection between them can be welding, perhaps rivet, or closely be connected by the cooperation of hole and pin.Flexible substrates 42 rear ends are fixed on the blade 2, and are same, it with blade 2 between to be connected can be welding or riveted joint or tight fit connection.Blade 3 is provided with the U-shaped draw-in groove 31 that matches with this location grab 41.After blade 3 passes the slit 5 of blade 2 front ends, draw-in groove 31 just fastening on the location grab 41 of substrate 42 front ends.And flexible substrates 42 is provided with the projection of being convenient to push 6, can be welding or riveted joint or tight fit being connected between this substrate 42 and the projection 6 and connects.Be provided with clearance position 7 with these projection 6 corresponding positions on the blade 2.A side relative with this clearance position 7 on blade 2 also is provided with the elongated slot 9 of being convenient to substrate 42 strains.Pin the projection 6 of elasticity handler 4 front ends, just blade 3 can be taken out from blade 2, strengthened the practicality and the convenience of this multipurpose cutter replacing blade 3 greatly, after the cutting edge wearing and tearing or destruction of blade 3, the blade 3 that can more renew easily and the blade 3 of different cutting edges.
In order to guarantee the security of cutter, be provided with the blade cover 12 that entangles blade 3 exposed parts at the front end of blade 3.Blade cover 12 adopts plastic cement to make, and directly is enclosed within on the blade 3, and can be retracted in the handle of a knife with blade 2 one.And as shown in Figure 4, blade 3 can be designed to different planforms, to realize different functions of use.
