Description

Novel flip folding knife

Technical Field

The utility model relates to a folding sword technical field specifically is a novel flip folding knife.

Background

The traditional folding knife (as shown in fig. 7) comprises a handle shell and a knife body, wherein the rear end of the knife body is movably connected to the front end of the handle shell through a pin shaft, and a containing opening for containing the knife body is formed in the inner side of the handle shell; therefore, when the hand-held electric knife is used, the knife body can rotate by taking the pin shaft as the center of a circle, when a user holds the handle shell, the hand is easily cut by the knife body, and the use is unsafe. And after in the opening of accomodating in the blade folding into handle casing, because blade and handle casing only through round pin axle swing joint, the condition of rotating out handle casing appears easily in the blade, and the security after folding is not good, appears accidentally injuring easily. To this end, we propose a new flip folding knife.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel flip folding knife to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a novel flip folding knife comprises a handle shell, wherein the front end of the handle shell is movably connected to the rear end of a protection frame through a pin shaft, and the inner side of the handle shell is provided with a containing opening for containing the protection frame;

the inside blade of accomodating groove that is used for accomodating the blade that is equipped with of the front end of fender bracket, the blade accomodates the groove the front end side be equipped with rather than integrated into one piece's arch. Through bellied setting, be convenient for roll the fender bracket and the blade out handle casing, convenient to use.

The front end in groove is accomodate to the blade passes through connecting pin swing joint in the rear end of blade, and the rear end middle part of blade is equipped with the rectangle and leads to the groove, insert to the blade after the rectangle leads to the groove and accomodate inslot wall at the both ends of connecting pin run through the rectangle.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model, through the arrangement of the protective frame, the cutter body can not rotate towards the handle shell when in use, thus avoiding the cutter body from cutting the hand when the user holds the handle shell; and the handle casing uses the round pin axle as the centre of a circle to the fender bracket direction rotation for the fender bracket is accomodate again and is accomodate in accomodating the opening, and through the setting of fender bracket, can accomodate the blade in the blade of fender bracket inside accomodates the groove like this, and the blade can not rotate out the handle casing at will, improves the security.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: the utility model provides a novel folding sword of flip, includes handle casing 1, handle casing 1's front end is through 3 swing joint in the rear end of fender bracket 4 of round pin axle, handle casing 1's inboard is equipped with the opening 2 of accomodating that is used for accomodating fender bracket 4, the inside blade that is used for accomodating blade 8 that is equipped with of fender bracket 4's front end is accomodate groove 5, the front end that the blade was accomodate groove 5 passes through 7 swing joint in the rear end of blade 8 of connecting pin.

The side edge of the front end of the blade accommodating groove 5 is provided with a bulge 6 which is integrally formed with the blade accommodating groove. Through the setting of arch 6, be convenient for rotate handle casing 1, convenient to use with fender bracket 4 and blade 8.

The middle part of the rear end of the knife body 8 is provided with a rectangular through groove 9, and the two ends of the connecting pin 7 penetrate through the rectangular through groove 9 and then are inserted into the inner wall of the knife body accommodating groove 5.

Specifically, when the combined type electric knife is used, the front end of the protective frame 4 is pulled out through the accommodating opening 2 in the handle shell 1 through the protrusion 6, and then the knife body 8 is rotated by taking the connecting pin 7 as a circle center, so that the knife point and the knife edge of the knife body 8 are rotated out of the knife body accommodating groove 5 (as shown in fig. 2);

then, the handle case 1 is rotated toward the protection frame 4 around the pin shaft 3, so that the protection frame 4 is accommodated in the accommodating opening 2 again, and the rear end of the blade 8 is located in the blade accommodating groove 5 (in the use state shown in fig. 6). Due to the arrangement of the protection frame 4, when the handle is in use, the cutter body 8 can not rotate towards the handle shell 1, so that the cutter body 8 can be prevented from cutting hands when a user holds the handle shell 1.

When the folding knife needs to be carried out, the front end of the protective frame 4 is pulled out through the containing opening 2 on the handle shell 1 through the bulge 6, and then the knife body 8 is rotated by taking the connecting pin 7 as the center of circle, so that the knife point and the knife edge opening of the knife body 8 are rotated into the knife body containing groove 5 (as shown in the state of fig. 3);

then with handle casing 1 use round pin axle 3 as the centre of a circle to the rotation of fender bracket 4 direction for the fender bracket 4 accomodate again in accomodating opening 2 (as the state shown in fig. 4) can, through the setting of fender bracket 4 like this, can accomodate blade 8 in the blade of the inside of fender bracket 4 accomodates the groove 5, blade 8 can not rotate out handle casing 1 at will, improves the security.

The traditional folding knife (as shown in fig. 7) comprises a handle shell 1 and a knife body 8, wherein the rear end of the knife body 8 is movably connected to the front end of the handle shell 1 through a pin shaft 3, and a containing opening 2 for containing the knife body 8 is arranged on the inner side of the handle shell 1;

therefore, when the hand-held electric knife is used, the knife body 8 can rotate by taking the pin shaft 3 as the center of a circle, when a user holds the handle shell 1 by hands, the hand is easily cut by the knife body 8, and the use is unsafe. And after the blade 8 is folded into the accommodating opening 2 in the handle shell 1, because the blade 8 and the handle shell 1 are only movably connected through the pin shaft 3, the blade 8 is easy to rotate out of the handle shell 1, the safety after folding is poor, and accidental injury is easy to occur.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
