Description

Technical Field

[0001] It relates to the field of daily life, and particularly to a riveted pair of scissors. Background Art

[0002] A pair of scissors usually consists of a rotor part, a stator part and a rivet. Among them, the rotor part is composed of a rotor blade ("rotating blade") and a rotor handle ("rotating handle"), and the stator part is composed of a stator blade ("fixed blade") and a stator handle ("fixed handle"). However, the existing scissors can be opened at a large angle. The larger the angle, the more obvious the blades face outwards, and the higher the risk of hand injury when picking up the scissors; the existing scissors have a large rotation angle, which makes it difficult for the human hand to control. At the same time, the amplitude of the blades facing outwards increases, enhancing the possibility of blade hand injury. Content of the Utility Model

The limiting mechanism can limit the included angle between the first blade assembly and the second blade assembly to rotate within the included angle range between the fully unfolded state and the fully closed state. In the fully unfolded state, the included angle between the first blade assembly and the second blade assembly is the maximum rotation angle β; in the fully closed state, the included angle between the first blade assembly and the second blade assembly is 0°.

[0005] Further, the maximum rotation angle β is 30° - 45°, 45° - 60° or 60° - 75°. Specifically, it can be 30° - 35°, 35° - 40°, 40° - 45°, 45° - 50°, 55° - 60°, 60° - 65°, 65° - 70°, 70° - 75°.

[0085] To make the purpose, technical solution and advantages clearer, the following will further describe the implementation mode in detail with reference to the drawings.

[0086] Embodiment 1

[0087] AsFigure 1 As shown, the scissors 1 shown in this embodiment include a first blade assembly 11, a second blade assembly 12, and a limiting mechanism 13. The limiting mechanism 13 connects the first blade assembly 11 and the second blade assembly 12 and can limit the rotation angle between the first blade assembly 11 and the second blade assembly 12 in the natural unfolding state and the fully closed state within a preset range.

[0088] The first blade assembly 11 includes a first blade 111, a first cutting edge 112, a first extension 115, a first connecting portion 116, and a first handle 117. The first cutting edge 112 is located at the side end of the first blade 111. One side of the first cutting edge 112 facing the second blade 121 forms a cutting surface, and the surface of the first cutting edge 112 abutting against the second blade 121 is a flat surface. The first extension 115 and the first connecting portion 116 are located at the intersection of the first blade 111 and the first handle 117. The front end of the first blade 111 is the sharp and pointed first cutting edge 112, and the end is a long arc-shaped handle portion. In the middle of the front end inside the first handle 117, there is a card slot for accommodating the long arc-shaped handle portion at the end of the first blade 111. The first extension 115 is located at the outer end of the first blade 111, and the first connecting portion 116 is located at the inner end of the first blade 111. The first extension 115 can be sleeved with the first handle 117 made of non-metallic materials such as rubber and plastic. The first handle 117 has a finger ring for the little finger to the index finger to pass through and hold.

[0089] The second blade assembly 12 includes a second blade 121, a second cutting edge 122, a second extension 125, a second connecting portion 126, and a second handle 127. The second cutting edge 122 is located at the side end of the second blade 121. One side of the second cutting edge 122 facing the first blade 111 forms a cutting surface, and the surface of the second cutting edge 122 abutting against the first blade 111 is a flat surface. The second extension 125 and the second connecting portion 126 are located at the intersection of the second blade 121 and the second handle 127. The front end of the second blade 121 is the sharp and pointed second cutting edge 122, and the end is a long arc-shaped handle portion. In the middle of the front end inside the second handle 127, there is a card slot for accommodating the long arc-shaped handle portion at the end of the second blade 121, that is, the top of the second cutting edge 122 of the second blade 121 is inserted into the groove of the second handle 127 and fixed. The second extension 125 is located at the outer end of the second blade 121, and the second connecting portion 126 is located at the inner end of the second blade 121. The second extension 125 can be sleeved with a second handle 127 made of a different material. The second handle 127 is a streamline open handle designed according to ergonomics for pressing operation by the thumb or the root of the thumb.

[0090] As Figure 2 and Figure 3As shown, when the scissors need to change from the natural unfolded state to the fully closed state, a force is applied to the second handle 127 of the scissors 1 in the direction of the first handle 117, causing the second handle 127 to move in the direction close to the first handle 117. The distance between the first connecting portion 116 and the second connecting portion 126 decreases, that is, the opening angle β of the scissors 1 becomes smaller. Until the first blade portion 112 and the second blade portion 122 coincide and move downward during the movement. The surface of the first blade portion 112 abutting against the second blade 121 becomes flat, and the surface of the second blade portion 122 abutting against the first blade 111 becomes flat. The special-shaped hole 132 rotates around the special-shaped rivet 131 and approaches the first blade portion 112. At this time, the scissors 1 change from the natural unfolded state to the fully closed state. When the scissors need to change from the fully closed state to the natural unfolded state, after canceling the force applied to the second handle 127 of the scissors 1 in the direction of the first handle 117, rely on the gravity moment or apply a reverse force. At this time, the second handle 127 moves in the direction away from the first handle 117. The distance between the first connecting portion 116 and the second connecting portion 126 increases, that is, the opening angle of the scissors 1 becomes larger. Until the surface of the first blade portion 112 abutting against the second blade 121 becomes flat and the surface of the second blade portion 122 abutting against the first blade 111 becomes flat and moves to the first blade portion 112 and the second blade portion 122 coincide and move upward during the movement. The special-shaped hole 132 rotates around the special-shaped rivet 131 and moves away from the first blade portion 112. At this time, the scissors 1 are restored from the fully closed state to the natural unfolded state.

[0091] The limiting mechanism 13 includes a special-shaped rivet 131, a special-shaped hole 132, and a fixing hole 133.

[0092] As Figure 4 shown, the shape of the fixing hole 133 is a racetrack shape.

[0093] As Figure 5 and Figure 6 shown, the special-shaped rivet 131 includes a nail column 1318 and a nail head 1319. The nail column 1318 includes a first side surface 1311, a second side surface 1312, a third side surface 1313, and a fourth side surface 1314. From the cross-section of the nail column 1318, the first side surface 1311 and the third side surface 1313 are straight line segments, and the second side surface 1312 and the fourth side surface 1314 are arcs, so that the cross-section of the nail column 1318 is approximately racetrack-shaped. The fixing hole 133 is a rectangular columnar structure approximately elliptical that matches the special-shaped rivet 131 and coincides with the racetrack shape of the fixing hole 133 so that it can pass through the fixing hole 133.

[0094] In this embodiment, the special-shaped rivet 131 has a rectangular columnar structure, specifically including a special-shaped rivet head 1319 and a special-shaped rivet column 1318. The rivet column 1318 passes through the connecting special-shaped hole 132 and the fixing hole 133 in sequence and is deformed and riveted, so that the rivet head 1319 abuts against the outside of the second blade 121, and the end of the rivet column 1318 coincides with the outside of the first blade 111.

[0095] As Figure 7 shown, the special-shaped hole 132 is a string shape with a certain inclination angle, that is, a hole with a concave middle and arc-shaped ends. The special-shaped hole 132 includes a first stop portion 1321, a second stop portion 1322, a first guiding portion 1323, a third stop portion 1324, a fourth stop portion 1325 and a second guiding portion 1325. The first stop portion 1321, the second stop portion 1322, the third stop portion 1324 and the fourth stop portion 1325 are straight line segments, which are used to stop the rotation of the rivet column 1318 so as to limit the rotation angle range. The first guiding portion 1323 and the second guiding portion 1325 are arcs, which are used to guide the relative rotation of the rivet column 1318. The extension line of the straight line where the first stop portion 1321 and the fourth stop portion 1325 are located intersects at point O and has an included angle β. The relative rotation angle range of the rivet column 1318 and the rivet column 1318, that is, the relative rotation angle range of the first blade assembly 11 and the second blade assembly 12 is 0 to β, and the included angle β is preferably 30 to 75°, and more preferably 45 to 60°.

[0096] Specifically, as Figure 8 、 9 shown, the rivet column 1318 penetrates the special-shaped hole 132. When the scissors 1 are in the natural unfolded state or the fully closed state, the special-shaped hole 132 rotates around the rivet column of the special-shaped rivet 131. Specifically, the central axes of the special-shaped hole 132, the rivet column 1318 and the fixing hole 133 completely coincide, and the center is represented by point P. After the rivet column 1318 penetrates the special-shaped hole 132, when the scissors 11 are in the natural unfolded state or the fully closed state, in fact, the special-shaped hole 132 and the rivet column 1318 rotate relatively. When the scissors 1 are in the fully closed state, the first stop portion 1321 abuts against the first side surface 1311, and the third stop portion 1324 abuts against the third side surface 1313, so as to be limited; when the scissors 1 are transformed from the fully closed state to the natural unfolded state, the special-shaped hole 132 rotates counterclockwise around the special-shaped rivet 131 with point P as the center. At this time, the first stop portion 1321 moves away from the first side surface 1311, and the fourth stop portion 1324 moves away from the third side surface 1313, and the relative rotation angle changes within the range of 0 to β; when the scissors 1 are in the natural unfolded state, the fourth stop portion 1325 abuts against the second side surface 1312, and the second stop portion 1322 abuts against the first side surface 1311, so as to be limited.

[0097] Embodiment 2

[0098] As shown Figures 10 - 14 in the figure, the scissors 2 shown in this embodiment include a first blade assembly 21, a second blade assembly 22, and a limiting mechanism. The limiting mechanism can limit the included angle between the first blade assembly 21 and the second blade assembly 22 to rotate within the range of the natural unfolding state and the fully closed state. The first blade assembly 21 has a first magnet 214, and the second blade assembly 22 has a second magnet 224. When in the fully closed state, the first magnet 214 and the second magnet 224 are arranged with the same poles facing each other to drive the first blade assembly 21 and the second blade assembly 22 to return to the natural unfolding state. The distance d from the center point P of the special-shaped rivet to the center point of the magnet accounts for 0.2 of the length of the scissor blade part.

[0099] The first blade assembly 21 includes a first blade, a first blade part, a first magnetic attraction part 213, a first magnet 214, a first extension part, a first connection part, and a first handle. The first blade part is located at the side end of the first blade. One side of the first blade part facing the second blade forms a blade surface, and the surface of the first blade part abutting against the second blade is a flat surface. The first extension part and the first connection part are located at the intersection of the first blade and the first handle. The front end of the first blade is a sharp and pointed first blade part, and the end is a long strip arc-shaped handle part. In the middle of the front end inside the first handle, there is a card slot for accommodating the long strip arc-shaped handle part at the end of the first blade. The first extension part is located at the outer end of the first blade, and the first connection part is located at the inner end of the first blade. The first extension part can be sleeved with non-metallic materials such as rubber and plastic. The first handle has a finger ring for the fingers to pass through. The first magnetic attraction part 213 is arranged between the fixing hole and the first handle, and the first handle has a finger ring for the little finger to the index finger to pass through and hold.

[0100] The second blade assembly 22 includes a second blade, a second blade part, a second magnetic attraction part 223, a second magnet 224, a second extension part, a second connection part, and a second handle. The second blade part is located at the side end of the second blade. One side of the second blade part facing the first blade forms a blade surface, and the surface of the second blade part abutting against the first blade is a flat surface. The second extension part and the second connection part are located at the intersection of the second blade and the second handle. The front end of the second blade is a sharp and pointed second blade part, and the end is a long strip arc-shaped handle part. In the middle of the front end inside the second handle, there is a card slot for accommodating the long strip arc-shaped handle part at the end of the second blade, that is, the top of the second blade part of the second blade is inserted into the groove of the second handle and fixed. The second extension part is located at the outer end of the second blade, and the second connection part is located at the inner end of the second blade. The second extension part can be sleeved with a second handle made of non-metallic materials such as rubber and plastic. The second handle is a streamline open handle designed according to ergonomics for the thumb or the root of the thumb to press and operate. The second magnetic attraction part 223 is arranged between the special-shaped hole and the second handle. In this embodiment, the limiting mechanism is the same as that in Embodiment 1.

[0101] As Figures 15 - 17As shown, the first magnetic attraction part 213 and the second magnetic attraction part 223 have the same structure and are respectively used to attract the first magnet 214 and the second magnet 224. The first magnetic attraction part 213 includes a first magnetic attraction front-end hole 2131, a first magnetic attraction enclosing part 2132, and a first magnetic attraction end hole 2133. The first magnetic attraction part 213 has a frustum shape in cross section. The first magnetic attraction enclosing part 2132 is a surface with a gradually decreasing diameter. The diameter of the first magnetic attraction front-end hole 2131 is larger than that of the first magnetic attraction end hole 2133. The first magnetic attraction front-end hole 2131 faces the second blade 121, and the first magnetic attraction end hole 2133 faces the outside. The first magnet 214 has an axisymmetric structure and includes a first magnet front-end face 2141, a first magnet front enclosing part 2142, a first magnet rear enclosing part 2143, and a first magnet rear-end face 2144. The first magnet front-end face 2141 is larger than the first magnet rear-end face 2144. The first magnet front enclosing part 2142 is slightly larger than the first magnet rear enclosing part 2143, so that the first magnet rear-end face 2144 and the first magnet rear enclosing part 2143 pass through the first magnetic attraction end hole 2133 and are fixed by the first magnetic attraction end hole 2133 at the intersection of the first magnet rear enclosing part 2143 and the first magnet front enclosing part 2142. At this time, the first magnetic attraction enclosing part 2132 is on the first magnet front enclosing part 2142 and the first magnetic attraction front-end hole 2131 and the first magnet front-end face 2141 are on the same horizontal plane.

[0102] The first magnet 214 and the second magnet 224 are of the same type. It is easy to understand that when the first magnet 214 approaches the second magnet 224, the two magnets will repel and move away from each other, thereby providing a driving force for the scissors to change to the natural unfolding state.

[0103] Applying a force to the second handle of the scissors 2 in the direction of the first handle causes the second handle to move in the direction of approaching the first handle, and the distance between the first connecting part and the second connecting part decreases, that is, the opening angle of the scissors 2 becomes smaller until the scissors 2 change from the natural unfolding state to the fully closed state.

[0104] If the force applied to the second handle of the scissors 2 in the direction of the first handle is withdrawn at this time, the two relatively arranged first magnets 214 and second magnets 224 have a repulsive force. Under the action of the repulsive force, the second handle moves in the direction away from the first handle, and the distance between the first connecting part and the second connecting part increases, that is, the opening angle of the scissors 2 becomes larger until the scissors 2 automatically recover from the fully closed state to the natural unfolding state.

[0105] Embodiment 3

[0106] As Figure 18As shown, the scissors 3 include a first blade assembly 31, a second blade assembly 32 and a limiting mechanism. The first blade assembly 31 includes a first blade, a first cutting edge, a first magnetic attraction portion 313, a first magnet 314, a first extension portion, a first connecting portion and a first handle; the second blade assembly 32 includes a second blade, a second cutting edge, a second magnetic attraction portion 323, a second magnet 324, a second extension portion, a second connecting portion and a second handle.

[0107] The difference between this embodiment and Embodiment 2 is that the positions of the first magnetic attraction portion 313 and the first magnet 314 on the first blade assembly 31 are adjusted, and the first magnetic attraction portion 313 and the first magnet 314 are arranged in front of the fixing hole; and the positions of the second magnetic attraction portion 323 and the second magnet 324 on the second blade assembly 32 are adjusted, and the second magnetic attraction portion 323 and the second magnet 324 are arranged in front of the special-shaped hole. At this time, there is a larger setting space, so a greater torque can be provided.

[0108] Embodiment 4

[0109] As Figure 19 As shown, the scissors 4 include a first blade assembly 41, a second blade assembly 42 and a limiting mechanism. The first blade assembly 41 includes a first blade, a first cutting edge, a first magnetic attraction portion 413, a first magnet 414, a first extension portion, a first connecting portion, a first handle, a third magnetic attraction portion 418 and a third magnet 419; the second blade assembly 42 includes a second blade, a second cutting edge, a second magnetic attraction portion 423, a second magnet 424, a second extension portion, a second connecting portion, a second handle, a fourth magnetic attraction portion 428 and a fourth magnet 429.

[0110] The difference between this embodiment and Embodiment 2 is that a third magnetic attraction portion 418, a third magnet 419, a fourth magnetic attraction portion 428 and a fourth magnet 429 are newly added. The first magnetic attraction portion 413 and the first magnet 414, the third magnetic attraction portion 418 and the third magnet 419 are arranged on both sides of the fixing hole of the first blade assembly 41, and the second magnetic attraction portion 423 and the second magnet 424, the fourth magnetic attraction portion 428 and the fourth magnet 429 are arranged on both sides of the special-shaped hole of the second blade assembly 42. Such an arrangement can provide a greater torque.
