Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is done and describes clearly and completely further.

Embodiment

As shown in Figures 2 and 3: a kind of safe operating knife that the present embodiment provides, comprise blade 1 and handle of a knife 2, be connected with security card slot 3 in the front end of described handle of a knife 2 by bearing pin 4, by the Access Division A31 suitable with the back of described blade 1 and with the afterbody of described blade 1, suitable Access Division B32 forms described security card slot 3.

Preferably:

Described Access Division A31 is provided with downward opening draw-in groove, the width value of described draw-in groove and the one-tenth-value thickness 1/10 of blade 1 suitable, to ensure that the back of blade can enter in the draw-in groove of Access Division A.

The length value of described Access Division A31 and the straight back of the body length value of blade 1 suitable, with ensure the point of a knife position of blade be exposed to outside, with avoid impact use.

The longitudinal length value of described Access Division B32 and the width value of blade 1 afterbody suitable, be placed in the B of Access Division to ensure that blade afterbody can block completely.

The draw-in groove width value of the wedging position 321 of described Access Division B32 and handle of a knife 2 and the one-tenth-value thickness 1/10 of handle of a knife 2 suitable, to ensure handle of a knife 2 and the fastening clamping of Access Division B32.

Described blade 1 is connected for detachable with between handle of a knife 2.

Security card slot 3 can be rotated along bearing pin 4, and what simultaneously security card slot 3 was fixed on the afterbody that handle of a knife 2 also can strengthen further blade 1 and handle of a knife 2 junction bears dynamics.

Described security card slot 3 is preferably integral structure, to process and to be connected.

Safe operating knife described in the utility model in use, security card slot 3 can be pressed forward, make it in closure state (see Fig. 2), such blade back and afterbody just can snap in the draw-in groove of security card slot 3, make blade 1 firmly be fixed on the front end of handle of a knife 2, operator can pin security card slot 3 to strengthen applying dynamics; Finish using, security card slot 3 can be holded up, make it in opened condition (see Fig. 3), blade 1 exits from security card slot 3.

Visible in sum: the safe operating knife that this utility model provides is by increasing security card slot, the blade caused because of misoperation not only can be effectively avoided to fracture and blade obscission, and the person of being convenient to operation exerts a force to blade, significantly improve the processing safety of user; Further, it is simple that scalpel provided by the utility model also has structure, assembling and the advantage such as easy to use, applied widely, has practicality and application prospect.

Finally be necessary described herein: the foregoing is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
