Description

Technical Field

[0001] This utility model relates to the field of scissors technology, specifically to a hair scissors. Background Technology

[0002] Scissors are an important hair styling tool. Traditional hair scissors are mostly connected to the handle and the blade as one piece or welded together. When using this type of hair scissors, the parallel plane of the handle is hindered and the fingers are restricted when inserting into the ring. The fingers and wrist joints must rotate at any angle depending on the cutting angle. Hairdressers often experience finger pain or wrist joint injury due to improper adjustment.

[0003] Chinese patent application CN206780414U discloses an adjustable hair scissors, including a stationary blade handle and a moving blade handle that are cross-connected, a convex tube located between the stationary blade handle and the stationary blade ring, a screw that passes through the base of the stationary blade ring and the convex tube and is matched and connected to a fastening nut, a convex post located between the moving blade handle and the moving blade ring, a muffler installed at one end of the convex post and threadedly connected to a through hole, a second fastening nut and an arc-shaped bracket that are threaded to both ends of the first stud, a third fastening nut that is threaded to one end of the second stud, a U-shaped bracket that is threaded to the other end of the second stud, pin holes respectively set at both ends of the U-shaped bracket, a connecting pin that passes through the pin holes, and a circular ring connected to the U-shaped bracket through the connecting pin.

[0004] However, the aforementioned adjustable hair scissors all use nuts and studs to connect the convex post and the arc-shaped bracket, as well as the arc-shaped bracket and the U-shaped bracket. When using the scissors, the nuts need to be tightened to maintain the locked connection between the convex post and the arc-shaped bracket, and between the arc-shaped bracket and the U-shaped bracket. In other words, during use, the hairdresser needs to loosen the nuts and studs again to adjust the grip angle, and then tighten the nuts again after adjustment before using the scissors again, which is quite inconvenient.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a hair scissors with a multi-directional adjustable and flexible finger ring to solve the above-mentioned problems in the existing technology.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a hair scissors, including a moving blade, a moving blade handle, a stationary blade, and a stationary blade handle, wherein the moving blade and the stationary blade are hinged by a pivot, characterized in that: the moving blade handle is provided with a connecting arm, one end of the connecting arm is provided with a first rotating member, and the other end is provided with a first finger ring, the connecting arm is rotatably engaged with the moving blade handle through the first rotating member, and the first finger ring is provided with a second rotating member, the first finger ring is rotatably engaged with the connecting arm through the second rotating member.

[0008] By adopting the above technical solution: the rotational connection between the connecting arm and the moving blade handle, and the rotational connection between the first finger ring and the connecting arm, the first finger ring can be adjusted in multiple directions and angles relative to the moving blade handle. This allows it to keep in line with the movement of the user's thumb during the trimming process, effectively reducing discomfort caused by prolonged trimming. Furthermore, during use, the thumb can always maintain stable contact with the first finger ring, improving the stability and accuracy of controlling the scissors.

[0009] The aforementioned hair scissors can be further configured such that: the first rotating component includes a first connecting bolt, the first connecting bolt is rotatably fitted with a plurality of first bearings, the moving blade handle is provided with a first connecting port, the first connecting bolt passes through the first connecting port, the end of the first connecting bolt away from the connecting arm is provided with a first external thread, and the first connecting bolt is threadedly connected to a first limiting component through the first external thread.

[0010] By adopting the above technical solution: the first bearing reduces the frictional force when the connecting arm rotates relative to the moving blade handle, improving the smoothness of the connecting arm rotation. At the same time, multiple first bearings are set on the first connecting bolt to distribute the radial load of the first connecting bolt, ensuring smooth and stable rotation and avoiding jamming or shaking. This achieves the ease and precision of adjusting the angle of the connecting arm. In addition, the first limiting member is threaded to the end of the first connecting bolt to achieve axial limiting of the first connecting bolt, preventing the connecting arm from accidentally coming off or axially moving. When the connecting arm does not need to rotate, the first limiting member can be tightened to keep the relative position between the moving blade handle and the connecting arm fixed. Furthermore, when it is necessary to maintain or replace the connecting arm or the first bearing, the first limiting member can be disengaged from the first connecting bolt to achieve quick disassembly of the connecting arm and the first bearing, improving the convenience of scissor maintenance.

[0011] The aforementioned hair scissors can be further configured such that: the second rotating component includes a second connecting bolt, the second connecting bolt is rotatably fitted with a plurality of second bearings, the connecting arm has a second connecting port, the second connecting bolt passes through the second connecting port, the end of the second connecting bolt away from the first finger ring has a second external thread, and the second connecting bolt is threadedly connected to a second limiting component through the second external thread.

[0012] By adopting the above technical solution: the inner ring of the second bearing abuts against the inner circumferential surface of the second connecting bolt, and the outer circumferential surface abuts against the inner wall of the second connecting port, the friction force when the first finger ring rotates relative to the connecting arm is reduced, and the smoothness of the rotation of the first finger ring is improved. This allows the user to easily and precisely fine-tune the rotation angle of the first finger ring to adapt to the user's grip posture. In addition, the second limiting member is threaded to the end of the second connecting bolt to limit the axial movement of the first connecting bolt, preventing the first finger ring from axially loosening or shifting relative to the second connecting port during frequent operation, thus improving the stability of the linkage between the first finger ring and the connecting arm. When the first finger ring does not need to rotate, the second limiting member can also be tightened to keep the relative position between the connecting arm and the first finger ring fixed.

[0013] The aforementioned hair scissors can be further configured as follows: a first positioning boss is provided in the first connecting port, a first limiting ring is provided in the first bearing, the first limiting ring abuts against the end face of the first positioning boss, a second positioning boss is provided in the second connecting port, a second limiting ring is provided in the second bearing, the second limiting ring abuts against the end face of the second positioning boss, a receiving cavity is provided in the second connecting port, and a second limiting member is provided in the receiving cavity.

[0014] By adopting the above technical solution: the first limiting ring contacts the end face of the first positioning boss during the installation of the first bearing, realizing the rapid installation and positioning of the first bearing; the second limiting ring can also contact the end face of the second positioning boss, quickly positioning and installing the second bearing into the second connection port. This simplifies the installation method of the first and second bearings and improves the convenience of assembling various parts. At the same time, the first limiting ring is located at the edge of the first bearing, which can shield and protect the first bearing and the first connection port; the second limiting ring is located at the edge of the second bearing, which can shield and protect the second bearing and the second connection port, preventing foreign objects or liquids from entering the first and second connection ports and causing increased rotational friction, thus effectively extending the service life of the scissors.

[0015] The aforementioned hair scissors can be further configured such that: an elastic washer is provided between the connecting arm and the first bearing, and between the first limiting member and the first bearing, and the elastic washer is inserted through the first connecting bolt.

[0016] By adopting the above technical solution, the elastic washer can reduce the friction generated by the contact between the end face of the connecting arm and the outer surface of the moving blade handle, and the end face of the first limiting member and the outer surface of the moving blade handle, and can fill the gap between them, preventing the connecting arm from shaking or loosening during rotation, ensuring high precision and gapless feel during the rotation of the connecting arm, and improving the feel of the scissors when using them.

[0017] The aforementioned hair scissors can be further configured such that: a buffer part is provided on the side of the moving blade handle near the stationary blade handle, an installation hole is provided on the end face of the buffer part, a limiting edge extends outward from the edge of the end face of the buffer part, the limiting edge and the buffer part form an installation cavity, and a buffer element is inserted into the installation cavity.

[0018] By adopting the above technical solution, the buffer can absorb the impact force of the collision between the moving blade handle and the stationary blade handle, reduce the noise when the moving blade handle and the stationary blade handle are opened and closed, and avoid muscle soreness caused by long-term use, thus improving the operating comfort. In addition, the limiting edge of the buffer part and the end face of the buffer part form a mounting cavity, and the inner wall of the limiting edge can contact the outer surface of the buffer part, improving the stability of the connection between the buffer part and the buffer part, and at the same time facilitating the replacement of the buffer part.

[0019] The aforementioned hair scissors can be further configured such that: the stationary blade handle has a second finger ring, the stationary blade handle has a protrusion on the side away from the moving blade handle, the protrusions form a finger groove between the stationary blade handle, and a finger support extends from the outer periphery of the second finger ring on the side away from the stationary blade handle.

[0020] By adopting the above technical solution: when holding the scissors, the index and middle fingers are placed on both sides of the protrusion, and the finger grooves on both sides of the protrusion are arc-shaped, which can fit the fingertips of the index and middle fingers. The ring finger is inserted into the second finger ring, and the fingertip of the little finger contacts the outer surface of the finger support. This significantly enhances the perception and control of the lateral grip force on the static blade handle, improves the overall stability and accuracy of operation, and enhances the fit and anti-slip properties when holding the scissors, reducing hand fatigue during long-term operation.

[0021] The beneficial effects of this utility model are as follows:

[0022] First, the first finger ring rotates in conjunction with the connecting arm, and the connecting arm rotates in conjunction with the moving blade handle. When the moving blade rotates, the first finger ring can move synchronously with the thumb. Compared with existing scissors that are adjusted by tightening nuts and bolts and remain fixed during use, the first finger ring of this application can always be adjusted to a suitable position and angle when the moving blade rotates relative to the stationary blade, maintaining stable contact with the thumb. This improves the stability and precision of operating the scissors, allowing the user to maintain a more comfortable grip posture when trimming, reducing finger wear or soreness caused by prolonged use. At the same time, the connecting arm is rotatably connected to the moving blade handle through the first bearing, and the first finger ring is rotatably connected to the connecting arm through the second bearing, reducing the friction when the first finger ring rotates, improving the smoothness of the rotation, and enabling flexible movement of the first finger ring in multiple directions and angles, thus improving the applicability of the scissors.

[0023] Secondly, the first connecting bolt is installed in the first connecting port through the first limiting member, and the second connecting bolt is installed in the second connecting port through the second limiting member. This ensures the rotation capability of the first finger ring while preventing the connecting arm from moving relative to the moving blade handle along the axial direction of the first connecting bolt and the first finger ring from moving relative to the connecting arm along the axial direction of the second connecting bolt, thus improving the stability of the first finger ring during movement. At the same time, tightening the first limiting member can keep the connecting arm in a fixed relative position to the moving blade handle, and tightening the second limiting member can keep the first finger ring in a fixed relative position to the connecting arm, achieving flexibility and stability in angle and orientation adjustment, and enabling various different ways of using the scissors.

Detailed Implementation

[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figures 1 to 7 The hair scissors shown include a movable blade 1, a movable blade handle 11, a stationary blade 2, and a stationary blade handle 21. The movable blade 1 and the stationary blade 2 are hinged together by a pivot 3. The movable blade handle 11 is provided with a connecting arm 4. One end of the connecting arm 4 is provided with a first rotating member 41, and the other end is provided with a first finger ring 5. The connecting arm 4 is rotatably engaged with the movable blade handle 11 through the first rotating member 41. The first finger ring 5 is provided with a second rotating member 51, and the first finger ring 5 is rotatably engaged with the connecting arm 4 through the second rotating member 51. The rotatable connection between the connecting arm 4 and the movable blade handle 11, and the rotatable connection between the first finger ring 5 and the connecting arm 4, enables multi-directional and multi-angle positional adjustment of the first finger ring 5 relative to the movable blade handle 11. This allows it to move in sync with the user's thumb during trimming, effectively reducing discomfort during prolonged trimming. Furthermore, during use, the thumb can always maintain stable contact with the first finger ring 5, improving the stability and precision of manipulating the scissors.

[0035] like Figure 2 , Figure 3 The moving blade 1 shown includes a moving blade handle 11. The moving blade handle 11 has a first connection port 12. The first connection port 12 has a first positioning boss 13. The moving blade handle 11 has a buffer part 14 on the side near the stationary blade handle 21. The end face of the buffer part 14 has a mounting hole. The edge of the end face of the buffer part 14 extends outward to a limiting edge 141. The limiting edge 141 and the buffer part 14 form a mounting cavity 142. A buffer member 15 passes through the mounting cavity 142. The first connection port 12 is used to install a first rotating member 41, so that the relative rotation of the connecting arm 4 and the moving blade handle 11 is more stable. The buffer member 15 on the upper end face of the buffer part 14 can absorb the vibration when the moving blade 1 and the stationary blade 2 are closed, reducing the impact of vibration on the user.

[0036] like Figure 4The stationary blade handle 21 shown has a second finger ring 22. A protrusion 23 is located on the side of the stationary blade handle 21 away from the moving blade handle 11. The protrusion 23 forms a finger groove 24 between the stationary blade handle 21 and the second finger ring 22 has a finger rest 25 extending from its outer periphery away from the stationary blade handle 21. When holding the scissors, the index and middle fingers are placed on either side of the protrusion 23. The finger grooves 24 on both sides of the protrusion 23 are arc-shaped, fitting snugly against the fingertips of the index and middle fingers. The ring finger is inserted into the second finger ring 22, and the little finger's pad contacts the outer surface of the finger rest 25. This significantly enhances the perception and control of lateral grip on the stationary blade handle 21, improving overall stability and precision, while also enhancing grip fit and anti-slip properties, reducing hand fatigue during prolonged operation.

[0037] like Figure 5 The first rotating component 41 shown includes a first connecting bolt 411, which passes through the first connecting port 12. The first connecting bolt 411 has a first external thread 412 at the end away from the connecting arm 4. The first connecting bolt 411 is threadedly connected to a first limiting component 43 through the first external thread 412. The first connecting bolt 411 is rotatably fitted with a plurality of first bearings 42. The first bearings 42 are provided with a first limiting ring 421, which abuts against the end face of the first positioning boss 13. The connecting arm 4 has a second connecting port 44, and a second positioning boss 441 is provided in the second connecting port 44. The first bearing 42 reduces the frictional force when the connecting arm 4 rotates relative to the moving blade handle 11, improving the smoothness of the connecting arm 4's rotation. At the same time, multiple first bearings 42 are provided on the first connecting bolt 411, which can distribute the radial load of the first connecting bolt 411, ensuring smooth and stable rotation and avoiding jamming or shaking. This achieves the ease and precision of adjusting the angle of the connecting arm 4. In addition, the first limiting member 43 is threaded to the end of the first connecting bolt 411, realizing the axial limiting of the first connecting bolt 411 and preventing the connecting arm 4 from accidentally coming off or axially moving. When the connecting arm 4 does not need to rotate, the first limiting member 43 can be tightened to keep the relative position between the moving blade handle 11 and the connecting arm 4 fixed. When it is necessary to maintain or replace the connecting arm 4 or the first bearing 42, the first limiting member 43 can be disengaged from the first connecting bolt 411, which can achieve quick disassembly of the connecting arm 4 and the first bearing 42, improving the convenience of scissor maintenance.

[0038] An elastic washer 45 is provided between the connecting arm 4 and the first bearing 42, and between the first limiting member 43 and the first bearing 42. The elastic washer 45 passes through the first connecting bolt 411. The elastic washer 45 can reduce the friction generated by the contact between the end face of the connecting arm 4 and the outer surface of the moving blade handle 11, and between the end face of the first limiting member 43 and the outer surface of the moving blade handle 11, and can fill the gaps between them, preventing the connecting arm 4 from shaking or loosening during rotation, ensuring high precision and no gaps during the rotation of the connecting arm 4, and improving the feel of the scissors when using them.

[0039] like Figure 6 The second rotating component 51 shown includes a second connecting bolt 511. The end of the second connecting bolt 511 away from the first finger ring 5 is provided with a second external thread 512. The second connecting bolt 511 is rotatably engaged with a plurality of second bearings 52. The second connecting bolt 511 passes through the second connecting port 44. The second bearing 52 is provided with a second limiting ring 521. The second limiting ring 521 abuts against the end face of the second positioning boss 441. The second connecting port 44 is provided with a receiving cavity 442. The second limiting member 53 is provided in the receiving cavity 442. The second connecting bolt 511 is threadedly connected to the second limiting member 53 through the second external thread 512. The inner ring of the second bearing 52 abuts against the inner circumferential surface of the second connecting bolt 511, and the outer circumferential surface abuts against the inner wall of the second connecting port 44. This reduces the frictional force when the first finger ring 5 rotates relative to the connecting arm 4, and improves the smoothness of the rotation of the first finger ring 5. This allows the user to easily and precisely fine-tune the rotation angle of the first finger ring 5 to adapt to the user's grip posture. In addition, the second limiting member 53 is threaded to the end of the second connecting bolt 511 and is used to axially limit the first connecting bolt 411 to prevent the first finger ring 5 from axially loosening or displacing relative to the second connecting port 44 during frequent operation. This improves the stability of the linkage between the first finger ring 5 and the connecting arm 4. When the first finger ring 5 does not need to rotate, the second limiting member 53 can also be tightened to keep the relative position between the connecting arm 4 and the first finger ring 5 fixed.

[0040] The working principle of this embodiment is as follows:

[0041] The user inserts their thumb into the first finger ring 5, places their index and middle fingers in the finger grooves 24 on both sides of the protrusion 23 of the stationary blade handle 21, inserts their ring finger into the second finger ring 22 on the stationary blade handle 21, and places their little finger against the finger rest 25 to hold the scissors. Then, the thumb drives the moving blade 1 to rotate around the central axis of the pivot 3, causing the moving blade 1 to separate from the stationary blade 2 and the moving blade handle 11 from the stationary blade handle 21. The first finger ring 5 moves synchronously with the thumb. At this time, the first finger ring 5 rotates relative to the connecting arm 4, and the connecting arm 4 rotates relative to the moving blade handle 11. The first finger ring 5 and the thumb maintain a stable relative position, making the user's grip on the scissors more natural and the opening and closing of the scissors smoother, reducing the risk of finger wear or soreness caused by prolonged use.

[0042] It should be noted that hairdressing scissors can be divided into flat scissors and thinning scissors, and the moving blade and stationary blade of this application can be set to the corresponding types as needed.

[0043] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
