This problem not only affects the cutting efficiency of the scissors, but also increases the user's physical exertion and reduces the user experience. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0034] The first scissors body 100 has a connected first cutting edge area 101 and a first matching area 102, the second scissors body 200 is arranged crosswise with the first scissors body 100 and has a connected second cutting edge area 201 and a second matching area 202, the portion of the second scissors body 200 in the second cutting edge area 201 and the portion of the first scissors body 100 in the first cutting edge area 101 abut each other, and the portion of the second scissors body 200 in the second matching area 202 and the portion of the first scissors body 100 in the first matching area 102 are spaced apart. The connecting assembly includes a bolt 301 that passes through the first matching area 102 and the second matching area 202 in sequence, and the first scissors body 100 and the second scissors body 200 are respectively rotatably mounted on the bolt 301 and can both rotate around the central axis of the bolt 301.

[0035] According to the above structure provided in the present embodiment, in the low friction resistance scissors provided in the present embodiment, the first cutting edge area 101 and the second cutting edge area 201 of the first scissors body 100 and the second scissors body 200 for cutting abut against each other to achieve a good shearing effect. When the first scissors body 100 and the second scissors body 200 abut against each other, the first matching area 102 and the second matching area 202 for connecting the bolt 301 on the first scissors body 100 and the second scissors body 200 are spaced apart, which can significantly reduce the contact area of the first scissors body 100 and the second scissors body 200 during the shearing process, thereby effectively reducing the mutual friction between the first scissors body 100 and the second scissors body 200 during the shearing process, which is far superior to the prior art.

[0036] In another embodiment of this application, please refer to Figures 1 to 3 A bearing hole 103 is formed on the first scissors body 100, and the connecting assembly further includes a bearing 302 coaxially sleeved on the bolt 301 and located in the bearing hole 103. The first scissors body 100 is connected to the outer ring of the bearing 302, and the bolt 301 is connected to the inner ring of the bearing 302. According to the above structure provided in this embodiment, the first scissors body 100 connected to the outer ring of the bearing 302 can rotate more smoothly relative to the bolt 301 connected to the inner ring of the bearing 302, which helps to further reduce the mutual friction between the first scissors body 100 and the second scissors body 200 during the cutting process.

[0037] In another embodiment of this application, please refer to Figures 1 to 3 The connecting assembly further includes an inner sleeve 303 coaxially sleeved on the bolt 301 and abutting against the second scissors body 200. The inner sleeve 303 forms a first flange 331 for abutting against the second scissors body 200, and the bearing 302 is clamped between the first flange 331 and the head of the bolt 301. According to the above structure provided in this embodiment, the first flange 331 formed by the inner sleeve 303 can not only cooperate with the head of the bolt 301 to form a stable clamping of the bearing 302, but also facilitates the axial stability of the bolt 301 during the shearing process of the low-friction resistance scissors in this embodiment, thereby further facilitating the reduction of the mutual friction between the first scissors body 100 and the second scissors body 200 during the shearing process.

[0038] In another embodiment of this application, please refer to Figures 1 to 3The head of the bolt 301 and the first flange 331 each form an annular truncated cone 304 protruding toward the bearing 302 on one side thereof, and the head of the bolt 301 and the first flange 331 each abut against the inner race of the bearing 302 via their respective annular truncated cones 304 and are spaced apart from the outer race of the bearing 302. According to the structure provided in this embodiment, the head of the bolt 301 and the first flange 331 can each pass through the annular truncated cone 304 and abut only against the inner race of the bearing 302. This reduces frictional resistance between the first scissors body 100 connected to the outer race of the bearing 302 and the bolt 301, thereby facilitating the low-friction shears of this embodiment to achieve a better low-friction shearing effect.

[0039] In another embodiment of this application, please refer to Figures 1 to 3 The first scissors body 100 is formed with a first accommodating cavity 104 coaxially connected to the bearing hole 103. The first accommodating cavity 104 has a radial dimension larger than the bearing hole 103 and is further away from the second scissors body 200 relative to the bearing hole 103. The first scissors body 100 has a stepped surface 105 perpendicular to the bolt 301 formed at the junction of the bearing hole 103 and the first accommodating cavity 104. The outer ring of the bearing 302 is formed with a second flange 321 that abuts the stepped surface 105. According to the above structure provided in this embodiment, the second flange 321 formed on the outer ring of the bearing 302 and abutting the stepped surface 105 can limit the first scissors body 100 in the axial direction of the bolt 301, thereby replacing the traditional method of limiting the scissors body by the bolt 301. This can further significantly reduce the frictional resistance between the first scissors body 100 and the bolt 301, which is conducive to the low-friction resistance scissors of this embodiment having a better low-friction cutting effect.

[0040] In another embodiment of this application, please refer to Figures 1 to 3 The head of the bolt 301 abuts against the inner wall of the first accommodating cavity 104 along the radial direction of the bolt 301. According to the above structure provided in this embodiment, the first accommodating cavity 104 can stabilize the head of the bolt 301, thereby facilitating the axial stability of the bolt 301, thereby further reducing the mutual friction between the first scissors body 100 and the second scissors body 200 during the shearing process.

[0041] In another embodiment of this application, please refer to Figures 1 to 3The second scissors body 200 is formed with an inner sleeve receiving cavity 203 for accommodating the first flange 331. The first flange 331 abuts against the inner wall surface of the inner sleeve receiving cavity 203 along the radial direction of the bolt 301. According to the above structure provided in this embodiment, the inner sleeve receiving cavity 203 abutting against the first flange 331 can also stabilize the bolt 301 in the axial direction and further reduce the mutual friction between the first scissors body 100 and the second scissors body 200 during the shearing process.

[0042] In another embodiment of this application, please refer to Figures 1 to 3 The connection assembly further includes a nut 305 threadedly connected to the bolt 301. The first scissors body 100 and the second scissors body 200 are clamped between the nut 305 and the head of the bolt 301. A second accommodating cavity 204 for accommodating the nut 305 is formed on the second scissors body 200. The nut 305 abuts against the inner end surface of the second accommodating cavity 204 along the axial direction of the bolt 301. According to the above structure provided in this embodiment, the nut 305 disposed and abutting in the second accommodating cavity 204 has a more stable installation effect, can keep the bolt 301 axially stable and further reduce the mutual friction between the first scissors body 100 and the second scissors body 200 during the shearing process.

[0043] In another embodiment of this application, please refer to Figures 1 to 3 The second accommodating chamber 204 and the inner sleeve accommodating chamber 203 are spaced apart and connected via a through hole 205 provided on the second scissors body 200. The diameter of the through hole 205 is smaller than the diameter of the second accommodating chamber 204 and the diameter of the inner sleeve accommodating chamber 203, respectively, and is capable of allowing the bolt 301 to pass through. According to the above structure provided in this embodiment, the through hole 205 connected between the second accommodating chamber 204 and the inner sleeve accommodating chamber 203 can better limit the movement or rotation of the bolt 301, making the bolt 301 more axially stable and further reducing the mutual friction between the first scissors body 100 and the second scissors body 200 during the shearing process.

[0044] In another embodiment of this application, please refer to Figures 1 to 3 The first scissors body 100 and the second scissors body 200 are further connected to a handle 400. According to the above structure provided in this embodiment, the handle 400 connected to the first scissors body 100 and the second scissors body 200 is conducive to the user to more conveniently operate the low friction resistance scissors provided in this embodiment, with good use effect.

[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 replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
