[0002] In daily life, knives can be seen everywhere. Using knives can help people cut and process objects. There are many folding knives on the market. After using the knives, the knives can be put back into the handle for storage.

[0003] The defects of traditional knife handles: When most existing folding knife handles are used, when the blade is rotated out of the handle, the handle does not have a safety structure. When the blade is used to cut objects, the blade may rotate, which is not only inconvenient to use, but also the blade can easily scratch the user's hand. In addition, when using the knife to cut hard objects, it is inconvenient to apply pressure to the blade because the back of the blade is thin.

[0004] Therefore, there is an urgent need for a handle of a knife and a tool that can solve the above problems. Utility Model Content

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figure 1-5 As shown, in an embodiment of the present invention: a cutting tool provided with a safety lock structure comprises a handle body 1 and a blade 4 made of vanadium amide.

[0026] In specific operation, the surface of the handle body 1 is equipped with a limit frame 2, and the side of the limit frame 2 is equipped with a pulling block 201. One end of the pulling block 201 is fixedly installed with a connecting block 202, and one end of the connecting block 202 is fixedly installed with a return spring 203. The side of the return spring 203 is equipped with a trapezoidal clamping block 204. The interior of the limit frame 2 is equipped with a fixed clamping plate 3.

[0027] A pressing rod 301 is fixedly installed on the top of the fixed card plate 3, a limiting rod 302 is installed on the right side of the fixed card plate 3, a pushing spring 303 is installed on the bottom end of the fixed card plate 3, a connecting rod 304 is installed on the bottom end of the fixed card plate 3, a lifting plate 305 is fixedly installed on the bottom end of the connecting rod 304, and a fixed block 306 is fixedly installed on the bottom end of the lifting plate 305.

[0028] Through the above technical solution, the fixed block 306 can be moved by pressing the pressing rod 301, so that the fixed block 306 can be inserted into the circular groove opened on the surface of the vanadium hydride blade 4. In this way, the vanadium hydride blade 4 can be locked to prevent the vanadium hydride blade 4 from rotating during use to avoid accidental injury.

[0029] The interior of the handle body 1 is provided with a mounting shaft 101 , and the interior of the handle body 1 is provided with a group of rectangular grooves.

[0030] A group of rectangular holes and slots matching the size of the connecting block 202 are opened on the left side of the limiting frame 2, and the right side of the top of the return spring 203 is a downward inclined surface.

[0031] Through the above technical solution, the connection block 202 can be moved on the side of the limit frame 2 by pulling the pulling block 201, so that the return spring 203 can move horizontally.

[0032] A group of circular through holes that match the size of the pressing rod 301 are opened at the top of the limit frame 2, and an arc surface is provided at the bottom left end of the fixed clamping plate 3. A rectangular hole groove that matches the size of the limit rod 302 is opened on the right side of the limit frame 2. A circular hole groove is opened at the bottom end of the limit frame 2, and the connecting rod 304 is inserted through the circular hole groove opened at the bottom end of the limit frame 2.

[0033] Through the above technical solution, when the pressing rod 301 is pressed downward, the fixed clamping plate 3 will move downward. When the fixed clamping plate 3 moves below the reset spring 203, the fixed clamping plate 3 can be clamped and fixed by the reset spring 203 under the elastic force of the trapezoidal clamping block 204.

[0034] The present utility model also provides a vanadium nitride cutting tool, including a vanadium nitride blade 4, a pressing gasket 401 is fixedly installed on the surface of the vanadium nitride blade 4, a group of circular through holes that are adapted to the size of the installation shaft 101 are opened inside the vanadium nitride blade 4, and the size of the vanadium nitride blade 4 is adapted to the rectangular groove opened inside the handle body 1.

[0035] Through the above technical solution, the vanadium hydride blade 4 can be installed inside the handle body 1, and the vanadium hydride blade 4 can rotate around the installation axis 101 as the center of the circle.

[0036] A group of rectangular grooves are opened on the back of the vanadium nitride blade 4, and the pressing gasket 401 is fixedly installed in the rectangular groove. Two groups of circular grooves are opened on the right side of the surface of the vanadium nitride blade 4, and the fixed block 306 is adapted to the size of the circular grooves opened on the right side of the surface of the vanadium nitride blade 4.

[0037] Through the above technical solution, the fixed block 306 is inserted into the circular hole groove opened on the surface of the vanadium hydride blade 4, so that the vanadium hydride blade 4 can be limited, so that the vanadium hydride blade 4 can be locked when in use to prevent the vanadium hydride blade 4 from rotating during use.

[0038] In summary, the working principle of the present invention is as follows: when the vanadium amide blade 4 needs to be locked during use, after the vanadium amide blade 4 is rotated out from the inside of the handle body 1, the fixed card plate 3 can be made to slide inside the limit frame 2 by pressing the pressing rod 301. When the fixed card plate 3 slides, it will squeeze the reset spring 203, and as the fixed card plate 3 moves downward, it can move to the bottom end of the reset spring 203. After the fixed card plate 3 moves to the bottom end of the reset spring 203, the fixed card plate 3 can be limited and fixed by the reset spring 203. At this time, the fixed block 306 will also move with the movement of the fixed card plate 3. When the fixing block 306 is moved to the circular groove provided on the surface of the vanadium hydride blade 4, the vanadium hydride blade 4 can be limited and locked after being inserted into the circular groove provided on the surface of the vanadium hydride blade 4, which can effectively prevent the vanadium hydride blade 4 from rotating during use and prevent accidental injury during use. By arranging a pressing gasket 401 on the back of the vanadium hydride blade 4, when the vanadium hydride blade 4 is used to cut hard objects, the pressing gasket 401 can be pressed by the other hand, which can apply pressure to the pressing gasket 401, so that the vanadium hydride blade 4 can cut hard objects more easily.

[0039] The above are merely preferred embodiments of the present invention and do not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
