Description

Technical Field

[0001] The present disclosure relates to the technical field of cutting tools, and particularly to a pair of scissors. Background Art

For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0047] See Figures 1 to 17 As shown, this embodiment provides a pair of scissors, which includes a first scissor body 1, a second scissor body 2, a driving mechanism 4, and a lock 3; the first scissor body 1 is movably connected to the second scissor body 2. The first scissor body 1 includes a first handle 11 and a first blade 12, and the first handle 11 is provided with a mounting portion 111; the second scissor body 2 includes a second handle 21 and a second blade 22, and the second handle 21 is provided with a card slot; the driving mechanism 4 is used to drive the first scissor body 1 to move relative to the second scissor body 2 so that the first blade 12 and the second blade 22 are in an open state; the lock 3 is movably installed in the mounting portion 111; the lock 3 can be limited in the card slot so that the first blade 12 and the second blade 22 are in a closed state.

[0048] For the pair of scissors provided in this embodiment, the lock 3 is movably installed in the mounting portion 111. When storage is needed, see Figure 1 and Figure 2 As shown, the lock 3 is limited in the card slot, so that the first blade 12 and the second blade 22 are in a closed state. At the same time, the lock 3 is not easily disengaged from the card slot, and the locking effect is better, improving safety. When use is needed, just move the lock 3 out of the card slot, and the operation is very convenient.

[0049] In this embodiment, the first scissor body 1 serves as the stator part, and the second scissor body 2 serves as the rotor part.

[0050] In other embodiments, it is also possible that the first scissor body serves as the rotor part and the second scissor body serves as the stator part.

[0051] In some embodiments, the first handle 11 and the mounting portion 111 may be integrally formed. The second handle 21 and the card slot may also be formed by injection molding.

[0052] Exemplarily, the materials of the first handle 11 and the second handle 21 are both plastics.

[0053] In one embodiment, the latch 3 includes a bendable rod-shaped structure. The bendable rod-shaped structure includes a connecting portion 31 and a locking hook portion 32. The connecting portion 31 is connected to the locking hook portion 32. The connecting portion 31 is movably mounted on the mounting portion 111, and the locking hook portion 32 can be limited in the card slot.

[0054] Exemplarily, the latch 3 can be formed by cutting and bending a bendable metal rod-shaped material, which is convenient for processing and has a low cost. Exemplarily, the material of the latch 3 can be stainless steel. The bendable rod-shaped structure can undergo elastic deformation, which is convenient for movably mounting the connecting portion 31 on the mounting portion 111 to achieve rapid assembly.

[0055] In some embodiments, the cross-sectional shape of the metal rod-shaped material is circular.

[0056] In one embodiment, as shown in Figures 11 to 13 the connecting portion 31 includes a first rod portion 311 and a second rod portion 312, and the first rod portion 311 and the second rod portion 312 are coaxially arranged; as shown in Figure 9 and Figure 10 the mounting portion 111 is provided with a first mounting hole 1111 and a second mounting hole 1112. The first rod portion 311 is inserted into the first mounting hole 1111, and the second rod portion 312 is inserted into the second mounting hole 1112.

[0057] In this embodiment, the first mounting hole 1111 and the second mounting hole 1112 are coaxially arranged, and both the first mounting hole 1111 and the second mounting hole 1112 are blind holes.

[0058] Since the bendable rod-shaped structure can undergo elastic deformation, during assembly, the first rod portion 311 and the second rod portion 312 are pulled in opposite directions to increase the distance between the free ends of the first rod portion 311 and the second rod portion 312. Then, the first rod portion 311 is inserted into the first mounting hole 1111, and the second rod portion 312 is inserted into the second mounting hole 1112. After the bendable rod-shaped structure returns to its original state, the first rod portion 311 and the second rod portion 312 can be respectively limited in the first mounting hole 1111 and the second mounting hole 1112. Since the first rod portion 311 and the second rod portion 312 are coaxially arranged, it is ensured that the latch 3 can rotate around the axes of the first rod portion 311 and the second rod portion 312.

[0059] In other embodiments, the first mounting hole 1111 and the second mounting hole 1112 may also communicate to form a through hole.

[0060] In one embodiment, see Figure 11 As shown, the lock hook portion 32 includes a transverse rod 321, a first vertical rod 322 and a second vertical rod 323, one end of the transverse rod 321 is connected to one end of the first vertical rod 322, the other end of the transverse rod 321 is connected to one end of the second vertical rod 323, the other end of the first vertical rod 322 is connected to the first rod portion 311, and the other end of the second vertical rod 323 is connected to the second rod portion 312; the slot includes a first slot portion 211, and the transverse rod 321 is limited to the first slot portion 211.

[0061] Exemplarily, the transverse rod 321, the first vertical rod 322 and the second vertical rod 323 are integrally formed. When the transverse rod 321 rotates to align with the first slot 211, the second scissors body 2 will tend to move away from the first scissors body 1 under the action of the driving mechanism 4. At this time, the first slot 211 moves toward the transverse rod 321, so that the transverse rod 321 is limited in the first slot 211. At the same time, the inner wall of the first slot 211 can also be tightly pressed against the transverse rod 321, effectively preventing the transverse rod 321 from being separated from the first slot 211.

[0062] For example, see Figure 6 As shown, the first groove portion 211 can be an arc-shaped groove, and the cross-sectional shape of the groove wall of the arc-shaped groove is a minor arc, which is beneficial to reducing the movement resistance of the lock hook portion 32, making it convenient to press the transverse rod 321 into the first groove portion 211 when locking is required, and also convenient to move the transverse rod 321 out of the first groove portion 211 when in use.

[0063] In some embodiments, when the first clip 12 and the second clip 22 are in the closed state, there is a gap between the first handle 11 and the second handle 21, and the first handle 11 can move relative to the second handle 21 to disengage the lock buckle 3 from the slot.

[0064] Because the second scissors body 2 tends to move away from the first scissors body 1 under the action of the driving mechanism 4, there is a gap between the first handle 11 and the second handle 21 when the first cutting piece 12 and the second cutting piece 22 are in the closed state. When the lock buckle 3 needs to be moved out of the slot, the first handle 11 and the second handle 21 can be grasped first to make the first handle 11 move relative to the second handle 21 until the first handle 11 abuts against the second handle 21. At this time, the first groove portion 211 will move in the direction away from the transverse rod 321, so that the transverse rod 321 is disengaged from or partially disengaged from the first groove portion.

[0065] It should be understood that the lateral rod 321 can be disengaged or partially disengaged from the first groove 211 by adjusting the size of the gap and the depth of the first groove 211. Exemplarily, when the depth of the first groove 211 is less than the gap, the lateral rod 321 can be disengaged from the first groove 211 when the first handle 11 abuts against the second handle 21; when the depth of the first groove 211 is not less than the gap, the lateral rod 321 can be manually pushed away from the first groove 211 when the first handle 11 abuts against the second handle 21.

[0066] In one embodiment, referring to Figure 4 and Figure 6 as shown, the card slot further includes a second groove 212 and a third groove 213. The second groove 212 and the third groove 213 are respectively located on both sides of the first groove 211. The first vertical rod 322 is limited in the second groove 212, and the second vertical rod 323 is limited in the third groove 213. This can further enhance the locking effect and effectively prevent the locking hook portion 32 from disengaging from the card slot.

[0067] In this embodiment, both the second groove 212 and the third groove 213 communicate with the first groove 211, which is convenient for production and processing. Exemplarily, the second groove 212 and the third groove 213 are also arc-shaped grooves.

[0068] In other embodiments, the second groove 212 and the second groove 212 may not communicate with the first groove 211 either.

[0069] In one embodiment, referring to Figure 11 as shown, the angle α formed between the lateral rod 321 and the first vertical rod 322 is an obtuse angle, and the angle β formed between the lateral rod 321 and the second vertical rod 323 is an obtuse angle.

[0070] Exemplarily, the distance between the first vertical rod 322 and the second vertical rod 323 gradually increases in the direction from the lateral rod 321 to the connecting portion 31. Correspondingly, the distance between the second groove 212 and the third groove 213 also gradually increases in the direction from the lateral rod 321 to the connecting portion 31.

[0071] When the second handle 21 abuts against the first handle 11, the portions of the first vertical rod 322 and the second vertical rod 323 close to the lateral rod 321 will disengage from the second groove 212 and the third groove 213, which is convenient for unlocking. That is to say, when the scissors need to be used, after gripping the first handle 11 and the second handle 21, the contact area between the first vertical rod 322 and the second groove 212 decreases, and the contact area between the second vertical rod 323 and the third groove 213 decreases, which is beneficial to pushing the lock 3 away from the card slot by manual means or the like.

[0072] In some embodiments, the angle α formed between the transverse rod 321 and the first vertical rod 322 may be equal to the angle β formed between the transverse rod 321 and the second vertical rod 323.

[0073] In one embodiment, referring to Figure 12 and Figure 13 as shown, the bendable rod-shaped structure further includes an operation part 33, which is integrally formed with the transverse rod 321, and the operation part 33 is located outside the card slot.

[0074] By providing the operation part 33, it is convenient for the user to operate the latch 3, thereby facilitating the quick locking and unlocking of the first scissor body 1 and the second scissor body 2.

[0075] In one embodiment, referring to Figure 12 as shown, the transverse rod 321 includes a first sub-segment 3211 and a second sub-segment 3212. One end of the first sub-segment 3211 is connected to the first vertical rod 322, and one end of the second sub-segment 3212 is connected to the second vertical rod 323. The operation part 33 is connected between the other end of the first sub-segment 3211 and the other end of the second sub-segment 3212.

[0076] In some embodiments, the operation part 33 may be a U-shaped structure.

[0077] In some embodiments, referring to Figure 13 as shown, the operation part 33 includes a first bending segment 331, a second bending segment 332, and a third bending segment 333. The third bending segment 333 is connected between the first bending segment 331 and the second bending segment 332. The first bending segment 331 is connected to the first sub-segment 3211 to form a first U-shaped inwardly retracted part, and the second bending segment 332 is connected to the second sub-segment 3212 to form a second U-shaped inwardly retracted part.

[0078] The first U-shaped inwardly retracted part and the second U-shaped inwardly retracted part can apply a tangential pulling force to the second scissor body 2 in the closed state, thereby further restricting the second scissor body 2 from rotating relative to the first scissor body 1 and opening.

[0079] It should be noted that the form of the operation part 33 is not limited to the above two, and other forms can also be selected according to actual needs.

[0080] In this embodiment, all the corners of the latch 3 are smoothly transitioned to avoid stress concentration and reduce the risk of fracture.

[0081] In addition, the latch in the scissors provided in this embodiment takes the Figure 13 shown latch structure as an example. Of course, it can also be but not limited to Figure 11 and Figure 12 shown latch structures.

[0082] In one embodiment, referring to Figure 1 and Figure 3 As shown, the installation part 111 is provided with a fixing groove 1113, and the lock catch 3 can be limited in the fixing groove 1113.

[0083] During use, the lock catch 3 can be fixed in the fixing groove 1113 to prevent the lock catch 3 from shaking during the use of the scissors.

[0084] It should be understood that the structures of the fixing groove 1113 and the clamping groove are basically the same and will not be elaborated here.

[0085] In one embodiment, referring to Figure 3 As shown, the driving mechanism 4 includes a first magnetic member 41 and a second magnetic member 42. The first cutting blade 12 is provided with a first accommodating portion, and the second cutting blade 22 is provided with a second accommodating portion. The first magnetic member 41 is installed in the first accommodating portion, and the second magnetic member 42 is installed in the second accommodating portion. The magnetic property of the end of the first magnetic member 41 facing the second magnetic member 42 is opposite to the magnetic property of the end of the second magnetic member 42 facing the first magnetic member 41.

[0086] Exemplarily, the first accommodating portion can be a through hole or a blind hole, and the second accommodating portion can be a through hole or a blind hole.

[0087] In this embodiment, both the first accommodating portion and the second accommodating portion are through holes. The shape of the through hole can be circular.

[0088] Since the magnetic property of the end of the first magnetic member 41 facing the second magnetic member 42 is opposite to the magnetic property of the end of the second magnetic member 42 facing the first magnetic member 41, when the first cutting blade 12 and the second cutting blade 22 are in a closed state, the first magnetic member 41 and the second magnetic member 42 will repel each other and move away. Therefore, when the lock catch 3 disengages from the clamping groove, under the repulsive force, the second scissor body 2 will move relative to the second scissor body 2, causing the first cutting blade 12 and the second cutting blade 22 to be in an open state.

[0089] Exemplarily, both the first magnetic member 41 and the second magnetic member 42 can be magnets. The first magnetic member 41 is fixed in the first accommodating portion by magnetic attraction, and the second magnetic member 42 is fixed in the second accommodating portion by magnetic attraction.

[0090] In one embodiment, referring to Figure 3 and Figure 7As shown, the scissors further include a fixing portion 5; the first cutting blade 12 is provided with a positioning hole 121, and the second cutting blade 22 is provided with a limiting hole 221. The hole wall of the positioning hole 121 includes two opposite first arc-shaped walls 1211 and two opposite straight walls; the hole wall of the limiting hole 221 includes two opposite second arc-shaped walls 2215 and two opposite bent walls. The axis of the second arc-shaped wall 2215 coincides with the axis of the first arc-shaped wall 1211; the fixing portion 5 is limited in the positioning hole 121; the bent wall can abut against the side wall of the fixing portion 5 to limit the rotation angle of the first cutting blade 12 relative to the second cutting blade 22.

[0091] Exemplarily, refer to Figure 8 As shown, the fixing portion 5 includes an insertion portion 51 and a limiting portion 52, and the insertion portion 51 and the limiting portion 52 can be integrally formed. The insertion portion 51 passes through the limiting hole 221 and the positioning hole 121 and is limited in the positioning hole 121. The circumferential side wall of the positioning hole 121 is adapted to the circumferential side wall of the insertion portion 51, and the insertion portion 51 is fixed in the positioning hole 121; the limiting portion 52 is located on the side of the second cutting blade 22 away from the first cutting blade 12.

[0092] Since the axis of the second arc-shaped wall 2215 coincides with the axis of the first arc-shaped wall 1211, the first scissor body 1 can rotate relative to the second scissor body 2 around this axis. When the bent wall abuts against the side wall of the fixing portion 5, the rotation angle of the first cutting blade 12 relative to the second cutting blade 22 can be limited, that is, the maximum opening angle between the first cutting blade 12 and the second cutting blade 22 is limited.

[0093] In one embodiment, refer to Figure 7 As shown, the two straight walls are respectively a first straight wall 1212 and a second straight wall 1213; the two bent walls are respectively a first bent wall and a second bent wall. Refer to Figure 14 As shown, the first bent wall includes a first stop wall 2211 and a second stop wall 2212, the second bent wall includes a third stop wall 2213 and a fourth stop wall 2214. The first stop wall 2211 is parallel to the fourth stop wall 2214, and the distance between the first stop wall 2211 and the fourth stop wall 2214 is adapted to the distance between the two straight walls; the second stop wall 2212 is parallel to the third stop wall 2213, and the distance between the second stop wall 2212 and the third stop wall 2213 is adapted to the distance between the two straight walls;

[0094] Refer to Figure 14 As shown, when the first cutting blade 12 and the second cutting blade 22 are in the closed state, the fixing portion 5 is limited between the first stop wall 2211 and the fourth stop wall 2214; refer to Figure 15 As shown, when the first cutting blade 12 and the second cutting blade 22 are in the open state, the fixing portion 5 is limited between the second stop wall 2212 and the third stop wall 2213. Figure 16In the figure, the solid line indicates that the second scissor body is in the closed state, and the dashed line indicates that the second scissor body is in the open state. Combining Figures 14 to 16 it can be seen that the insertion part 51 is stationary, that is, the fixing part 5 is stationary. When the second blade rotates relative to the first blade, different parts of the two bent walls of the limiting hole can abut against different positions of the insertion part to limit the opening angle.

[0095] In some embodiments, referring to Figure 3 as shown, the number of the first magnetic member 41 and the second magnetic member 42 can both be one. The first magnetic member 41 is located on the side of the fixing part 5 close to the first handle 11, and the second magnetic member 42 is located on the side of the fixing part 5 close to the second handle 21.

[0096] Of course, the first magnetic member 41 and the second magnetic member 42 can also be respectively located on the sides of the fixing part 5 away from the first handle 11 and the second handle 21.

[0097] In other embodiments, referring to Figure 17 as shown, the number of the first magnetic member 41 and the second magnetic member 42 can also both be two. Taking the second magnetic member 42 as an example, the two second magnetic members 42 are respectively located on both sides of the fixing part 5.
