[0001] The utility model generally relates to the technical field of tools or learning supplies, and more specifically, to a pair of scissors. Background Art

[0002] Some existing scissors have a locking switch to prevent the scissors from accidentally opening when not in use, avoiding accidental scratches, especially for children. Due to the limited space of the scissors themselves, the space for turning the locking switch is relatively small, making it inconvenient for users to twist the locking switch with their fingers and affecting the user experience. Summary of the Utility Model

[0003] The scissors provided by the utility model are convenient to operate and have a good user experience.

[0004] According to a first aspect of the present utility model, there is provided a pair of scissors, comprising:

[0005] A body, including a first cutting blade, a second cutting blade, a first handle, and a second handle, wherein the first cutting blade is connected to the first handle, the second cutting blade is connected to the second handle, and the connection position between the first cutting blade and the first handle is rotatably connected to the connection position between the second cutting blade and the second handle;

[0006] A locking switch, disposed between the first handle and the second handle;

[0007] A sheath, sleeved outside the first cutting blade and the second cutting blade and detachably connected to the body;

[0008] Wherein, the sheath is configured to be detachably connected to the locking switch and capable of driving the locking switch to rotate relative to the body, so that the first handle and the second handle can be switched between a locking mode and an unlocking mode.

[0009] In some embodiments, one of the sheath and the locking switch is provided with a convex, and the other is provided with a groove, and the convex can be snapped into the groove.

[0010] After the convex can be snapped into the groove, the user can drive the locking switch to rotate relative to the body by rotating the sheath, realizing the switching between the unlocking mode and the locking mode.

[0011] In some embodiments, one end of the sheath along the length direction of the sheath is provided with an open end, and the open end faces the first cutting blade and the second cutting blade;

[0012] Wherein, the convex or the groove provided on the sheath is located at the end of the sheath along the length direction of the sheath.

[0013] Since the length of the sheath along the length direction of the sheath is relatively large, the clamping protrusion or the clamping groove is arranged at the end of the sheath, which is convenient for the user to hold the sheath and rotate the locking switch. In addition, when the user plugs and unplug the sheath, the clamping protrusion or the clamping groove will not affect the normal operation of the user.

[0014] In some embodiments, the clamping groove is a through groove structure, and both ends of the clamping groove penetrate through the edge of the locking switch;

[0015] And / or, the projection of the clamping groove on the first reference plane is a linear structure;

[0016] And / or, the projection of the clamping protrusion on the first reference plane is a linear structure;

[0017] And / or, the clamping protrusion extends along the width direction of the sheath;

[0018] Wherein, when the sheath is sleeved on the body, the first reference plane is arranged parallel to the width direction of the sheath, and the first reference plane is arranged perpendicular to the length direction of the sheath.

[0019] The clamping groove is a through groove structure, and both ends of the clamping groove penetrate through the edge of the locking switch, that is, the clamping groove has two openings, and the user can freely choose to slide the clamping protrusion into the clamping groove from one of the openings.

[0020] Wherein, the clamping protrusion extends along the width direction of the sheath, making full use of the limited space at the end of the sheath.

[0021] In some embodiments, the number of the clamping protrusions and the clamping grooves is multiple, the multiple clamping grooves are arranged at intervals and along the circumferential direction of the locking switch, and the multiple clamping protrusions are correspondingly clamped in the multiple clamping grooves.

[0022] The multiple clamping protrusions are correspondingly clamped in the multiple clamping grooves. In this way, when the user rotates the locking switch through the sheath, the force on the locking switch is relatively balanced, improving the stability and reliability during the mode switching process.

[0023] In some embodiments, the clamping groove penetrates through the edge of the locking switch.

[0024] That is, a clamping groove is formed by recessing along the edge of the locking switch towards the direction close to the center of the locking switch, so that the clamping protrusion of the sheath can directly slide from the edge of the locking switch into the clamping groove, or the clamping protrusion of the sheath can directly slide out of the clamping groove to outside the locking switch.

[0025] In some embodiments, along the radial direction of the locking switch, positioning protrusions are arranged between the sides of the multiple clamping grooves close to each other, and avoidance grooves are arranged between the sides of the multiple clamping protrusions close to each other, and the avoidance grooves are used to avoid the positioning protrusions.

[0026] That is, after a card slot is formed in the radial direction of the locking switch along the radial direction of the locking switch, a positioning protrusion is formed at the central part of the locking switch. In this way, the groove wall of the card slot along the radial direction of the locking switch is the outer wall of the positioning protrusion. After the clamping protrusion enters the card slot, the clamping protrusion can abut against the outer wall of the positioning protrusion, playing a role in alignment and central positioning.

[0027] In some embodiments, a vent hole is provided at the bottom of the avoidance groove.

[0028] That is, the vent hole is arranged between the two clamping protrusions, and the vent hole communicates with the open end of the sheath, avoiding situations such as blocking the trachea, esophagus, etc. after being accidentally swallowed by young users, so as to meet the requirements of relevant safety regulations.

[0029] In some embodiments, the projection of the clamping protrusion on the second reference plane is a polygonal structure;

[0030] And / or, the projection of the card slot on the second reference plane is a polygonal structure;

[0031] Wherein, the second reference plane is the plane where the length direction of the sheath and the width direction of the sheath are located when the sheath is sleeved on the body.

[0032] There are corners or tips on the outer wall of the clamping protrusion and the inner wall of the card slot, playing a certain limiting role and reducing the situation of sliding between the clamping protrusion and the card slot.

[0033] In some embodiments, the locking switch includes:

[0034] A rotary cap, detachably connected to the sheath;

[0035] A rotary column, passing through the first handle and the second handle and capable of rotating relative to the body. At least one of the first handle and the second handle is provided with a locking and cooperating portion, and the rotary column is detachably connected to the locking and cooperating portion.

[0036] The card slot is arranged on the end face of the rotary cap on the side away from the rotary column. The rotary column passes through the first handle and the second handle and can rotate relative to the body. At least one of the first handle and the second handle is provided with a locking and cooperating portion, and the rotary column is detachably connected to the locking and cooperating portion.

[0037] Exemplarily, the locking and cooperating portion can be a card hole or a clamping groove or other structures such as an end cap, as long as the rotary column can be detachably connected to the locking and cooperating portion by rotation.

[0038] An embodiment of the present utility model has the following advantages or beneficial effects:

[0039] The scissors provided by the embodiment of the present utility model, in the locking mode, the sheath is sleeved outside the first blade and the second blade, used to wrap the first blade and the second blade, avoiding the first blade and the second blade from injuring users, especially for the low-age user group, and improving the storage safety.

[0040] The locking switch is equivalent to a lock core, and the sheath is equivalent to a key. The sheath is used to screw the locking switch, facilitating the rotation operation of the locking switch. By borrowing the existing sheath, without increasing the cost, the convenience of user operation is improved, and the user experience is enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0058] This embodiment provides a pair of scissors. As Figure 1 shown, the pair of scissors includes a body 1, and the body 1 includes a first blade 11, a second blade 12, a first handle 13, and a second handle 14. The first blade 11 is connected to the first handle 13, the second blade 12 is connected to the second handle 14, and the connection position between the first blade 11 and the first handle 13 is rotatably connected to the connection position between the second blade 12 and the second handle 14.

[0059] Specifically, an included angle is formed between the first handle 13 and the second handle 14, the first blade 11 and the second blade 12 are cross - arranged, and the connection position between the first blade 11 and the first handle 13 is hingedly connected to the connection position between the second blade 12 and the second handle 14 through a rotating shaft 15, so that the first blade 11, the second blade 12, the first handle 13, and the second handle 14 form a structure similar to an X - shape. Among them, the rotating shaft 15 can be a screw, a rivet, etc.

[0060] When in use, the user's thumb and the other four fingers press the first handle 13 and the second handle 14 respectively, to drive the first handle 13 and the second handle 14 to rotate in directions approaching or moving away from each other, so as to realize the opening and closing of the first blade 11 and the second blade 12.

[0061] Among them, one of the first handle 13 and the second handle 14 is pressed by the four fingers and can be considered fixed during the operation, which can be called the stator part; the other of the first handle 13 and the second handle 14 is pressed by the thumb and is considered movable during the operation, which can be called the rotor part, and is controlled by pressing and lifting the thumb. Then, this pair of scissors can also be called a semi - automatic scissors.

[0062] As Figure 1 - Figure 2 shown, the pair of scissors further includes a locking switch 2, and the locking switch 2 is arranged between the first handle 13 and the second handle 14 to switch the first handle 13 and the second handle 14 between a locked mode and an unlocked mode.

[0063] In the unlocked mode, the locking switch 2 can be used to unlock the first handle 13 and the second handle 14, so that the first handle 13 and the second handle 14 can rotate freely, which is convenient for the first blade 11 and the second blade 12 to perform cutting operations; in the locked mode, the locking switch 2 can be used to fix the first handle 13 and the second handle 14, which is convenient for the storage of the scissors, and can prevent the first blade 11 and the second blade 12 from injuring the user, improving the safety during storage.

[0064] As Figure 2 shown, the pair of scissors further includes a sheath 3, and the sheath 3 is sleeved outside the first blade 11 and the second blade 12 and is detachably connected to the body 1.

[0065] In the locked mode, the sheath 3 is sleeved outside the first cutting blade 11 and the second cutting blade 12 for wrapping the first cutting blade 11 and the second cutting blade 12 to prevent the first cutting blade 11 and the second cutting blade 12 from damaging the user, especially for the low-age user group, and improve the storage safety.

[0066] Due to the space limitation of the scissors itself, the space for screwing the locking switch 2 is relatively small, making it inconvenient for the user to screw the locking switch 2 and affecting the user experience.

[0067] Therefore, the sheath 3 provided in this embodiment is configured to be detachably connected to the locking switch 2 and can drive the locking switch 2 to rotate relative to the body 1, so that the first handle 13 and the second handle 14 are switched between the locking mode and the unlocking mode.

[0068] For the scissors provided in this embodiment, the locking switch 2 is equivalent to a lock core, and the sheath 3 is equivalent to a key. Using the sheath 3 to screw the locking switch 2 facilitates the rotation operation of the locking switch 2. By borrowing the existing sheath 3, without increasing the cost, the convenience of user operation is improved and the user experience is enhanced.

[0069] In one embodiment, one of the sheath 3 and the locking switch 2 is provided with a clamping protrusion 31, and the other is provided with a clamping groove 21, and the clamping protrusion 31 can be clamped in the clamping groove 21.

[0070] Exemplarily, the sheath 3 is provided with a clamping protrusion 31, and the locking switch 2 is provided with a clamping groove 21; or the locking switch 2 is provided with a clamping protrusion 31, and the sheath 3 is provided with a clamping groove 21; or, both the sheath 3 and the locking switch 2 are provided with a clamping protrusion 31 and a clamping groove 21. The clamping protrusion 31 of the sheath 3 is clamped in the clamping groove 21 of the locking switch 2, and the clamping protrusion 31 of the locking switch 2 is clamped in the clamping groove 21 of the sheath 3 to achieve the double clamping effect. This embodiment takes the clamping protrusion 31 being provided on the sheath 3 and the clamping groove 21 being provided on the locking switch 2 as an example.

[0071] After the clamping protrusion 31 can be clamped in the clamping groove 21, the user can drive the locking switch 2 to rotate relative to the body 1 by rotating the sheath 3, realizing the switching between the unlocking mode and the locking mode.

[0072] In one embodiment, one end of the sheath 3 is provided with an open end, and the open end faces the first cutting blade 11 and the second cutting blade 12, so that the first cutting blade 11 and the second cutting blade 12 can enter the cavity of the sheath 3 through the open end.

[0073] Wherein, the clamping protrusion 31 or the clamping groove 21 provided on the sheath 3 is provided at the end of the sheath 3 along the length direction of the sheath 3.

[0074] Since the length of the sheath 3 in the length direction of the sheath 3 is relatively large, the clamping protrusion 31 or the clamping groove 21 is arranged at the end of the sheath 3, which is convenient for the user to hold the sheath 3 and rotate the locking switch 2. In addition, when the user inserts or removes the sheath 3, the clamping protrusion 31 or the clamping groove 21 will not affect the normal operation of the user.

[0075] Exemplarily, the number of the clamping protrusion 31 and the clamping groove 21 is one, and one clamping protrusion 31 is correspondingly clamped in one clamping groove 21, with a simple structure and convenient use.

[0076] Exemplarily, as Figure 3 - Figure 5 shown, the number of the clamping protrusion 31 and the clamping groove 21 is multiple, and the multiple clamping grooves 21 are arranged at intervals and along the circumferential direction of the locking switch 2, and the multiple clamping protrusions 31 are correspondingly clamped in the multiple clamping grooves 21. In this way, when the user rotates the locking switch 2 through the sheath 3, the force on the locking switch 2 is relatively balanced, improving the stability and reliability during the mode switching process.

[0077] For example, the number of the clamping protrusion 31 and the clamping groove 21 in this embodiment is two, the included angle between the two clamping protrusions 31 is 180°, the two clamping protrusions 31 are arranged along the width direction of the sheath 3, and the included angle between the two clamping grooves 21 is 180°.

[0078] Wherein, the clamping groove 21 penetrates through the edge of the locking switch 2, that is, a clamping groove 21 is formed by recessing along the edge of the locking switch 2 towards the direction close to the center of the locking switch 2, so that the clamping protrusion 31 of the sheath 3 can directly slide from the edge of the locking switch 2 into the clamping groove 21, or the clamping protrusion 31 of the sheath 3 can directly slide out of the clamping groove 21 to outside the locking switch 2.

[0079] In one embodiment, along the radial direction of the locking switch 2, a positioning protrusion 22 is arranged between the sides of the multiple clamping grooves 21 close to each other.

[0080] Exemplarily, after the clamping groove 21 is formed in the locking switch 2 along the radial direction of the locking switch 2, a positioning protrusion 22 is formed in the central part of the locking switch 2. In this way, the groove wall of the clamping groove 21 along the radial direction of the locking switch 2 and away from the edge of the locking switch 2 is the outer wall of the positioning protrusion 22. After the clamping protrusion 31 enters the clamping groove 21, the clamping protrusion 31 can abut against the outer wall of the positioning protrusion 22, playing a role of alignment and central positioning.

[0081] Wherein, as Figure 3 - Figure 5 shown, a relief groove 32 is arranged between the sides of the multiple clamping protrusions 31 close to each other. The relief groove 32 provides a certain accommodation space for the positioning protrusion 22, and the relief groove 32 is used to avoid the positioning protrusion 22, preventing the situation of unstable insertion between the clamping protrusion 31 and the clamping groove 21.

[0082] In one embodiment, a vent hole 33 is provided at the bottom of the avoidance groove 32. That is, the vent hole 33 is provided between two clamping protrusions 31, and the vent hole 33 communicates with the open end of the sheath 3, preventing situations such as blocking the trachea, esophagus, etc. after being accidentally swallowed by young users, so as to meet the requirements of relevant safety regulations.

[0083] In one embodiment, the projection of the clamping protrusion 31 on the second reference plane is a polygonal structure; and / or, the projection of the card slot 21 on the second reference plane is a polygonal structure; wherein, the second reference plane is the plane where the length direction and the width direction of the sheath 3 are located when the sheath 3 is sleeved on the body 1. The length direction of the sheath 3 is marked with L, the width direction of the sheath 3 is marked with B, the thickness direction of the sheath 3 is marked with H, and the length direction, width direction, and thickness direction of the sheath 3 are perpendicular to each other in pairs.

[0084] For example, the projection of the clamping protrusion 31 on the second reference plane and the projection of the card slot 21 on the second reference plane are triangular structures, and there are corners or tips on the outer wall of the clamping protrusion 31 and the inner wall of the card slot 21, which play a certain limiting role and reduce the occurrence of sliding between the clamping protrusion 31 and the card slot 21.

[0085] In another embodiment, the card slot 21 is a through slot structure, and both ends of the card slot 21 penetrate through the edge of the locking switch 2, that is, the card slot 21 has two openings, and the user can freely choose to slide the clamping protrusion 31 into the card slot 21 from one of the openings.

[0086] Exemplarily, the projection of the card slot 21 on the first reference plane is a linear structure, and the projection of the clamping protrusion 31 on the first reference plane is a linear structure; wherein, when the sheath 3 is sleeved on the body 1, the first reference plane is parallel to the width direction of the sheath 3 and perpendicular to the length direction of the sheath 3, that is, the first reference plane is the plane where the width direction and the thickness direction of the sheath 3 are located.

[0087] Wherein, the clamping protrusion 31 extends along the width direction of the sheath 3, making full use of the limited space at the end of the sheath 3.

[0088] In one embodiment, as Figure 5 shown, the locking switch 2 includes a rotary cap 201 and a rotary column 202. The rotary cap 201 is detachably connected to the sheath 3, and the card slot 21 is provided on the end face of the rotary cap 201 on the side away from the rotary column 202. The rotary column 202 passes through the first handle 13 and the second handle 14 and can rotate relative to the body 1. At least one of the first handle 13 and the second handle 14 is provided with a locking and cooperating part (not shown in the figure), and the rotary column 202 is detachably connected to the locking and cooperating part.

[0089] Exemplarily, the locking engagement portion can be optionally provided on a card hole or a clamping groove or an end cap or other structures on the first handle 13 and / or the second handle 14, as long as the rotating column 202 can be detachably connected to the locking engagement portion by rotation.
