[0002] Ferrous metal materials are a general term for iron, chromium and manganese in industry. It also includes alloys of these three metals, especially alloy ferrous metal steel and iron and steel. Alloy steel is a type of ferrous metal, mainly composed of iron, chromium, nickel and a small amount of other elements. It is widely used for its corrosion resistance, heat resistance and beautiful appearance. Scissors are double-edged tools for cutting sheet or linear objects such as cloth, paper, steel plates, ropes, round steel, etc. The two edges are staggered and can be opened and closed. Modern household scissors are mainly made of alloy steel.

[0003] A Chinese patent with application number CN201910734276.5 discloses a pair of scissors, including a movable blade controlled by a thumb and a stationary blade controlled by a ring finger. The two parts are rotatably connected and riveted fixed by a rivet.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when using scissors to cut some harder objects, the blades of the movable blade and the stationary blade are prone to wear, thereby making the scissors unusable, thereby reducing the service life of the scissors.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a pair of scissors for ferrous metal smelting and rolling products. Figure 1 The ferrous metal smelting and rolling product scissors include a movable blade 1 and a stationary blade 2, a connecting piece 3 is arranged between the movable blade 1 and the stationary blade 2, the movable blade 1 and the stationary blade 2 are rotatably arranged through the connecting piece 3, and the connecting piece 3 is detachably provided with a sharpening block 6. When the scissors are used to cut some harder objects and the blades of the movable blade 1 and the stationary blade 2 are worn, the sharpening block 6 can be removed, and then the blades of the movable blade 1 and the stationary blade 2 are sharpened again by the sharpening block 6. By setting the sharpening block 6, the worn blades can be sharpened, thereby extending the service life of the scissors.

[0033] Reference Figure 2 and 3 The connecting member 3 includes a column 32 and a cap 31 connected to the column 32. The column 32 is firstly penetrated by the movable blade 1, and then penetrated by the stationary blade 2. A clamping gasket 4 is provided on the side of the column 32 away from the cap 31. Specifically, the column 32 is provided with a limiting groove 33, the limiting groove 33 is provided around the outer periphery of the column 32, the bottom wall of the limiting groove 33 is flush with the stationary blade 2, the clamping gasket 4 is provided with a through hole for the column 32 to penetrate, the diameter of the through hole is slightly smaller than the diameter of the column 32, and the clamping gasket 4 is inserted into the limiting groove 33. In the present embodiment, the column 32 and the cap 31 are integrally formed, and the clamping gasket 4 is made of plastic with a certain deformation ability. In other embodiments, the column 32 and the cap 31 can also be connected by welding.

[0034] By setting the pressing gasket 4, the connection between the movable blade 1 and the stationary blade 2 is made tighter, thereby reducing the looseness between the movable blade 1 and the stationary blade 2 when the scissors cut some hard objects. When the pressing gasket 4 is worn, the pressing gasket 4 can be replaced. By setting the pressing gasket 4, the service life of the scissors is further extended.

[0035] Reference Figure 4 A connecting sleeve 5 is provided between the cap 31 and the sharpening block 6. The connecting sleeve 5 is provided with a mounting groove 52 for mounting the sharpening block 6. The connecting sleeve 5 is provided with a through hole 51 for the column 32 to penetrate at the bottom wall of the mounting groove 52. The side of the cap 31 close to the column 32 abuts against the bottom wall of the mounting groove 52 of the connecting sleeve 5.

[0036] A positioning block 7 is provided on the outer periphery of the sharpening block 6, and a positioning groove 8 for the positioning block 7 to be engaged is provided on the side wall of the mounting groove 52 of the connecting sleeve 5. The positioning groove 8 includes a through groove 82 and an engaging groove 81, wherein the through groove 82 is provided perpendicular to the side wall of the mounting groove 52, and the engaging groove 81 is provided around the inner side wall of the mounting groove 52. In this embodiment, the sharpening block 6 and the positioning block 7 are integrally formed, and in other embodiments, the sharpening block 6 and the positioning block 7 may also be connected by glue or bolts.

[0037] An elastic member 9 is provided between the sharpening block 6 and the connecting sleeve 5. One end of the elastic member 9 is connected to the bottom wall of the mounting groove 52, and the end of the elastic member 9 away from the bottom wall of the mounting groove 52 abuts against the side of the sharpening block 6 close to the connecting sleeve 5. When the sharpening block 6 is installed in the mounting groove 52, the upper end surface of the sharpening block 6 is flush with the surface of the connecting sleeve 5. In this embodiment, the elastic member 9 is a compression spring, and the elastic member 9 is connected to the connecting sleeve 5 by welding. In other embodiments, the elastic member 9 can be rubber or silicone with deformation ability.

[0038] When installing the sharpening block 6, first align the positioning block 7 with the penetration groove 82, then insert the sharpening block 6 into the installation groove 52, and the elastic member 9 is compressed. Finally, the sharpening block 6 is rotated so that the positioning block 7 enters the clamping groove 81. Under the rebound force of the elastic member 9, the positioning block 7 is tightly pressed against the upper wall of the clamping groove 81, so that the installation of the sharpening block 6 is more stable.

[0039] When the sharpening block 6 is used, the sharpening block 6 is rotated. When the positioning block 7 corresponds to the penetration groove 82, the force on the sharpening block 6 is released. Under the rebound force of the elastic member 9, the sharpening block 6 will be automatically ejected from the installation groove 52, making it more convenient to take the sharpening block 6.

[0040] The sharpening block 6 is vertically provided with a sharpening opening 61, and the contact area between the sharpening block 6 and the blade is increased by the opening of the sharpening opening 61. When sharpening, the blade is detected at the sharpening opening 61, and then polished up and down. By the opening of the sharpening opening 61, the blade can be more easily restored to sharpness.

[0041] The implementation principle of the scissors for ferrous metal smelting and rolling products in the embodiment of the present application is as follows: a movable blade 1 is connected to a stationary blade 2 through a connecting member 3, and a whetstone 6 is detachably provided on the connecting member 3. When the blades of the movable blade 1 and the stationary blade 2 are worn, the whetstone 6 can be removed and sharpened to restore the blades to sharpness, thereby extending the service life of the scissors.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
