If fig. 1, a special sword of cutting non-setting adhesive, including blade 2 and handle of a knife 1, blade 2 and handle of a knife 1 are for dismantling the connection, wherein, it places chamber 12 to be equipped with the blade that is used for holding blade 2 in the handle of a knife 1, the blade is placed chamber 12 and is the toper chamber of big-end-up, the blade portion of blade 2 stretches out 1 outer extension of handle of a knife and forms free end 22, the afterbody butt of blade 2 is fixed in the inner wall formation stiff end 21 that the chamber 12 was placed to the blade, place chamber 12 through the blade of seting up the link up handle of a knife in handle of a knife 1, fix blade 2 butt in the chamber 12 inner wall is placed to the blade, both realize fixedly through interference fit, when blade 2 damages, the application of force takes out blade 2 from handle of a knife 1, it can to change new blade again, this kind of detachable connected mode, moreover.

In this embodiment, the upper end of the blade placing cavity 12 is provided with a locking support placing cavity 11 communicated with the blade placing cavity, and a locking support 111 for compressing the blade fixing end 21 is arranged in the locking support placing cavity 11. The locking support column 111 applies external force to the blade fixing end 21, so that the fixing end 21 can be better fixed on the inner wall of the blade placing cavity 12, the stability is good, the blade is not easily influenced by the outside, and the connection is firm and reliable.

In this embodiment, the locking strut 111 is screwed into the locking strut placement chamber 11. The outer ring of the locking support column 111 is provided with an external thread, the inner ring of the locking support column placing cavity 11 is provided with an internal thread, the locking support column placing cavity and the internal thread are connected through threads, and the threaded connection structure is simple, the connection is reliable, and the manufacturing cost is low.

In this embodiment, the lower end of the blade placing cavity 12 is provided with a compressing part placing cavity 13 communicated with the blade placing cavity, and a compressing part sleeved on the outer ring of the blade 2 is arranged in the compressing part placing cavity 13. When the locking support column 111 rotates to continuously press the blade fixing end 21, the compression piece is stressed and compressed to store elastic potential energy, and when the blade 2 is damaged and needs to be taken out, the compressed elastic potential energy is released to assist the blade 2 to be taken out from the blade placing cavity.

In this embodiment, the compression member is a compression spring 131, and when the compression spring 131 is compressed, the compression spring can store a larger elastic potential energy, so that the force provided for taking out the blade is larger.

In this embodiment, the blade fixing end 21 is tapered with a large top and a small bottom. Because the blade placing cavity 12 is a tapered cavity with a large top and a small bottom, the shape of the blade fixing end 21 is kept consistent with that of the blade placing cavity 12, so that the blade can be fixed better, and the blade fixing end 21 is abutted and fixed on the tapered inner wall of the blade placing cavity 12 through a tapered inclined surface. Under the action of external force, the two are pressed tightly through the inclined plane to form self-locking force, so that fixation is realized. The fixing mode is simple and reliable, and the locking relation can be released at any time.

In this embodiment, blade stiff end 21 and blade are placed and are equipped with elastic rubber cover 211 between the chamber 12, because blade stiff end 21 is that the butt is fixed in the blade and places on the chamber 12 inner wall, contact site causes mechanical wear easily during the use, reduces the life of handle of a knife 1, and the chamber is placed to the protection blade that rubber elastic cover 211 can be fine, reduces wearing and tearing, increase of service life.

In this embodiment, the knife handle 1 is provided with a knife cap 3 for covering the free end 22 of the blade. In this embodiment, the knife cap 3 is a protective sleeve sleeved on the outer wall of the compression member placing cavity 13, and the knife cap 3 is mainly used for protecting the blade edge portion from external damage.

In the embodiment, the blade 2 is made of tungsten steel, the tool holder 1 is made of stainless steel, the tungsten steel is high in hardness, wear-resistant, high in strength and toughness and excellent in heat resistance and corrosion resistance, the manufactured tool has the advantages of being high in hardness, strength and wear resistance and the like, the stainless steel tool holder is firm and incomparable due to the fact that a high-frequency welding technology is adopted, the stainless steel tool holder portion can be recycled, resources are saved, and cost is reduced.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
