[0033] Please also read Figures 1 to 5 The split manual scissors provided in the embodiment of the present application are now described. The split manual scissors include a bolt 100, a first handle 201, a second handle 202, a blade 300 and a nut 400. Among them:

[0034] The bolt 100 has a cylindrical section 101, a square shaft section 102 and a threaded section 103 in the axial direction. The first handle 201 forms a through hole 211 and is connected to the cylindrical section 101 through the through hole 211. The second handle 202 forms a square hole 221 and is connected to the square shaft section 102 through the square hole 221. Two blades 300 are arranged flatly and are respectively clamped on the first handle 201 and the second handle 202. The blade 300 has a first clamping groove 301 that is recessed along the thickness direction. The first handle 201 and the second handle 202 respectively form an extension part 203 that is clamped in the first clamping groove 301 and abuts against the side wall of the first clamping groove 301. The bolt 100 penetrates the extension part 203 and the blade 300 along the depth direction parallel to the first clamping groove 301; the nut 400 is threadedly connected to the threaded section 103 to limit the freedom of the first handle 201, the second handle 202 and the blade 300 in the axial direction of the bolt 100.

[0035] According to the above structure provided by the present embodiment, the first handle 201 and the second handle 202 are respectively connected to the first slot 301 provided on the blade 300 through their respective extensions 203 and abut against the side wall of the first slot 301. After the first handle 201, the blade 300 and the second handle 202 are connected as a whole by the bolt 100, since the depth direction of the slot is parallel to the axial direction of the bolt 100, the first handle 201 and the second handle 202 can drive the blade 300 to rotate by interacting with the side wall of the first slot 301, thereby realizing the normal function of the scissors. When the handle is worn or damaged or needs to be replaced with a handle of a different style, by loosening the nut 400 and separating the blade 300 and the handle, the user can only replace the handle part without having to buy a new pair of scissors, which greatly saves the user's expenses. At the same time, due to the differentiated style design of the blade or the handle, the user can choose a handle of different design styles such as different materials, colors or shapes according to his own preferences and needs, so that the scissors are not only powerful, but also beautiful and personalized.

[0036] In another embodiment of the present application, please refer to Figures 1 to 5 , the side wall of the first slot 301 forms an opening for the extension portion 203 to pass through. According to the above structure provided in this embodiment, the opening provided on the side wall of the first slot 301 can make the first handle 201 and the second handle 202 better fit with the blade 300, thereby improving the rotation stability of the split manual scissors provided in this embodiment, and also facilitating the disassembly and assembly of the blade and the first handle 201 and the second handle 202.

[0037] In another embodiment of the present application, please refer to Figures 1 to 5 The blade 300 is formed with a receiving hole 302 parallel to the depth direction of the first slot 301, and the extension portion 203 is formed with a boss 231 engaged in the receiving hole 302. According to the above structure provided in this embodiment, the boss 231 provided on the extension portion 203 cooperates with the receiving hole 302 provided on the blade 300, so that the blade 300 and the extension portion 203 can be engaged more stably, which is conducive to further improving the rotation stability of the split manual scissors provided in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 5 , the through hole 211 and / or the square hole 221 are arranged on the boss 231. According to the above structure provided in this embodiment, the through hole 211 or the square hole 221 is arranged on the boss 231, and the first handle 201 and the second handle 202 can be connected by using a shorter bolt 100. On the one hand, it is beneficial to further make the split manual scissors provided in this embodiment have a thinner overall structure to reduce the overall weight and improve the comfort of use; on the other hand, it can increase the force load of the bolt 100, so that the split manual scissors in this embodiment can provide greater shearing force.

[0039] In another embodiment of the present application, please refer to Figures 1 to 5 The first handle 201 and / or the second handle 202 is provided with a second slot 204, the depth direction of the second slot 204 is set at an angle to the depth direction of the first slot 301, and the blade 300 has a lug 303 that is engaged with the second slot 204. According to the above structure provided in this embodiment, the second slot 204 set at an angle to the first slot 301 is conducive to providing a more stable engagement relationship between the blade 300 and the first handle 201 or between the blade 300 and the second handle 202, which is conducive to further improving the rotation stability of the split manual scissors provided in this embodiment.

[0040] In another embodiment of the present application, please refer to Figures 1 to 5, the depth direction of the first card slot 301 is perpendicular to the depth direction of the second card slot 204. According to the above structure provided in this embodiment, the second card slot 204 arranged perpendicular to the first card slot 301 is conducive to providing a more stable card connection relationship between the blade 300 and the first handle 201 or between the blade 300 and the second handle 202, which is conducive to further improving the rotation stability of the split manual scissors provided in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 5 The split manual scissors further include a bearing 500 sleeved on the cylindrical section 101, and the first handle 201 is also rotatably connected to the bolt 100 through the bearing 500. According to the above structure provided in this embodiment, the bearing 500 disposed between the first handle 201 and the bolt 100 is conducive to improving the smoothness of the rotation of the first handle 201 and the bolt 100, achieving the technical effects of labor saving and stable rotation.

[0042] In another embodiment of the present application, please refer to Figures 1 to 5 The first handle 201 and the second handle 202 are also provided with a receiving cavity 205, and the nut 400 and the bearing 500 are respectively received in the receiving cavity 205. According to the above structure provided in this embodiment, the receiving cavity 205 can improve the installation stability of the nut 400 and the bearing 500, and make the scissors have a thinner structure as a whole.

[0043] In another embodiment of the present application, please refer to Figures 1 to 5 The split manual scissors further include an anti-loosening gasket 600, which is arranged between the nut 400 and the bottom wall of the accommodating chamber 205. According to the above structure provided in this embodiment, the anti-loosening gasket 600 can further improve the installation stability of the nut 400, prevent the nut 400 from loosening, maintain the contact pressure between the blades 300 during cutting, and prevent the gap between the blades 300 from appearing during hair cutting, thereby preventing the hair from being caught.

[0044] In another embodiment of the present application, please refer to Figures 1 to 5 The split manual scissors further include a pressing plate 700 for pressing the bearing 500 in the accommodating cavity 205. According to the above structure provided in this embodiment, the pressing plate 700 can stably press the bearing 500 in the accommodating cavity 205.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
