Abstract
Description
Technical Field
[0001] This utility model relates to the field of scissors technology, specifically to anti-slip scissors. Background Technology
[0002] Scissors are an important hairdressing tool; hairdressers use scissors to trim hair.
[0003] Chinese utility model patent with publication number "CN220197757U" discloses a pair of hairdressing scissors, which includes: a first blade body and a second blade body. The first blade body includes a first blade and a first grip. The second blade body includes a second blade and a second grip. The second blade body and the first blade body are connected axially by a shaft. The first blade body rotates relative to the second blade body between an open position and a closed position with the shaft as a rotation center. The shaft defines a radially extending longitudinal axis, which points towards the second blade.
[0004] Combined with paragraphs
[0058] to
[0059] of the instruction manual and the appendix to the instruction manual Figure 2 , 3 It can be seen that although the first blade of the aforementioned hairdressing scissors can slide relative to the second blade during the opening and closing process to achieve the trimming effect, both the first and second blades of the aforementioned hairdressing scissors are single arc-shaped. When trimming hair, the first and second blades are clamped together, and the first and second blades cannot prevent the hair strands from sliding. That is, the hair strands are still prone to slide significantly along the blade axis, resulting in uneven trimming and poor trimming effect.
[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content
[0006] The purpose of this invention is to provide an anti-slip scissor that can reduce hair slippage and improve the trimming effect, so as to solve the above-mentioned problems existing in the prior art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: anti-slip shears, including a first blade body and a second blade body, the first blade body and the second blade body are hinged by a pivot, the first blade body is provided with a first handle, and the second blade body is provided with a second handle, characterized in that: the first blade body is provided with ripple-shaped toothed blades, and the first blade body and the second blade body rotate around the pivot to cause the blade teeth and the flat blade to open and close.
[0008] By adopting the above technical solution: during trimming, the first handle drives the first blade to rotate, and the second handle drives the second blade to rotate, causing the first and second blades to open. Then, the hair is inserted between the first and second blades, and then the first and second blades rotate in opposite directions to close. When closing, the hair is confined between the blades, preventing the hair from slipping excessively during trimming and causing uneven trimming. This, combined with the second blade, achieves the trimming of the hair, improving the precision of hair trimming.
[0009] The above-mentioned anti-slip shear can be further configured as follows: the toothed blade includes several first cutting edges in the shape of arcs, the first cutting edge is a concave arc with radius R1, R1=1.5~40mm, and the width of the first cutting edge is d, d=1~2mm.
[0010] By adopting the above technical solution: the first cutting edge can accommodate hair strands. When the first and second cutting edges work together to cut, the hair strands slide from the end of the first cutting edge into the bottom of the concave arc. Then, the arc-shaped sidewall on the other side of the concave arc limits the hair strands, stopping them from sliding. This ensures that the relative position remains stable during trimming. At the same time, the radius R1 of the concave arc and the width d of the first cutting edge can be set according to the trimming needs to achieve different trimming effects.
[0011] The above-mentioned anti-slip shear can be further configured such that: between each two adjacent sets of first cutting edges, there is a second cutting edge in the shape of an arc, the second cutting edge being a convex arc with a radius of R2, wherein R2 = 0.25~1mm.
[0012] By adopting the above technical solution: the blade is ripple-shaped. During cutting, some hair strands will stay at the second blade located between the two sets of first blades. The second blade is set in a convex arc shape, and one end of the second blade is connected to the end of the first blade on one side, and the other end is connected to the end of the first blade on the other side. The hair strands can smoothly slide into the first blade after passing through the second blade, thereby improving the first blade's ability to limit the hair strands and improving the hair care effect of the anti-slip scissors.
[0013] The above-mentioned anti-slip shear can be further configured such that: the first blade body includes a first blade surface and a second blade surface, the first blade surface and the second blade surface have an included angle α, the included angle α being in the range of 30°~50°.
[0014] By adopting the above technical solution: the first blade body is thinner on the side closer to the second blade body and relatively thicker on the other side. The connection surface between the thinner end and the thicker end forms the first blade surface and the second blade surface. The connection between the first blade surface and the second blade surface forms an included angle α, which is in the range of 30°~50°. This can maintain the sharpness of the teeth, ensure the structural strength of the first blade body, and effectively extend the service life of the anti-slip shear.
[0015] The above-mentioned anti-slip shears can be further configured as follows: the first handle is cylindrical, a first limiting boss is formed at the connection between the first handle and the first blade, a second limiting surface is provided on the side wall of the second blade near the second handle, and the second blade contacts or separates from the outer surface of the first limiting boss through the second limiting surface.
[0016] By adopting the above technical solution: the cylindrical first handle can better fit the fingertips, improve the stability of the fingers driving the first handle to rotate, and when the first blade and the second blade are closed, the first limiting boss contacts the second limiting surface, keeping the positions of the first blade and the second blade relatively fixed, preventing the first blade and the second blade from rotating excessively, and improving the stability of the anti-slip shear when it is closed.
[0017] The above-mentioned anti-slip shears can be further configured as follows: the second handle is cylindrical, a second limiting boss is formed at the connection between the second handle and the second blade, a first limiting surface is provided on the side wall of the first blade near the first handle, and the first blade contacts or separates from the outer surface of the second limiting boss through the first limiting surface.
[0018] By adopting the above technical solution: the second handle is also cylindrical, allowing the barber to place their fingers against the first or second handle as needed, thereby changing the direction of hair trimming. Furthermore, the second limiting protrusion on the second handle and the second blade engages with the first limiting surface on the first handle. Combining the first limiting protrusion on the first handle and the second limiting surface on the second handle, the stability of the anti-slip shears when closed is further improved, preventing wobbling when the first and second blades are closed.
[0019] The aforementioned anti-slip shears can be further configured such that: a first finger ring is provided at one end of the first handle relative to the first blade body, the first finger ring is integrally formed with the first handle, and a first support rod for supporting the finger is provided on one side of the first finger ring relative to the first handle.
[0020] By adopting the above technical solution, the fingers can be inserted into the first finger ring and the fingertips can contact the inner wall of the first finger ring, preventing the first handle from detaching from the fingers and improving the stability of the fingers driving the first handle to rotate, thereby improving the stability of the first blade body during trimming. In addition, the first support rod set at the rear of the first finger ring can support the little finger, reduce fatigue during long-term trimming, and improve the comfort of holding the anti-slip shears.
[0021] The aforementioned anti-slip shears can be further configured such that: a second finger ring is provided at one end of the second handle relative to the second blade body, the second finger ring is integrally formed with the second handle, and a second support rod for supporting the fingers is provided at a certain point relative to the second handle of the second finger ring.
[0022] By adopting the above technical solution, the second handle is also equipped with a second finger ring, which, together with the first finger ring, improves the barber's grip on the first and second handles of the anti-slip scissors and effectively prevents the first and second handles from falling off. In addition, the second support bar is also set on the outside of the second finger ring, which allows the barber to maintain a consistent grip posture when changing the grip direction according to the trimming needs, thus improving the barber's consistency during trimming.
[0023] The beneficial effects of this utility model are as follows: By setting ripple-shaped teeth on the first blade, the slippage of hair strands can be effectively restricted. Compared with traditional scissors where both blades are single arc-shaped, this application sets a concave arc-shaped first cutting edge at the teeth of the first blade and a convex arc-shaped second cutting edge between two adjacent sets of first cutting edges. This allows hair strands to slide into and be confined within the first cutting edge, preventing uneven cutting caused by excessive slippage of hair strands during trimming, thus improving the smoothness and consistency of hair styling. Simultaneously, a first limiting boss is set at the connection between the first handle and the first blade, and a first limiting surface is set on the side of the first handle. A second limiting boss is set at the connection between the second handle and the second blade, and a second limiting surface is set on the side of the second handle. The first limiting boss and the second limiting surface cooperate, and the second limiting boss and the first limiting surface cooperate, maintaining the stability when the first and second blades are closed. In addition, the first handle and the second handle are symmetrically provided with a first finger ring and a second finger ring, and the first finger ring is provided with a first support rod and the second finger ring is provided with a second support rod. When trimming hair, the barber can change the running position of the first blade and the second blade while maintaining the same grip posture, which improves the comfort of holding and trimming the non-slip scissors.
[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation
[0026] 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.
[0027] like Figures 1 to 9 The anti-slip scissors shown include a first blade 1 and a second blade 2, which are hinged together by a pivot 3. The first blade 1 has a first handle 4, and the second blade 2 has a second handle 5. The first blade 1 has ripple-shaped toothed blades 11. Rotation of the first blade 1 and the second blade 2 around the pivot 3 causes the toothed blades 11 to open and close. During trimming, the first handle 4 drives the first blade 1 to rotate, and the second handle 5 drives the second blade 2 to rotate, opening the first blade 1 and the second blade 2. Then, hair is inserted between the first blade 1 and the second blade 2, and then the first blade 1 and the second blade 2 rotate in opposite directions to close. When closed, the hair is confined within the toothed blades 11, preventing excessive slippage during trimming and resulting in uneven trimming. This, combined with the second blade 2, improves the precision of hair trimming.
[0028] For example, 3 to Figure 6 As shown, the cutting edge 11 includes several arc-shaped first cutting edges 12. Each first cutting edge 12 is a concave arc with a radius R1, where R1 = 1.5~40mm, and the width d of the first cutting edge 12 is 1~2mm. The first cutting edge 12 can accommodate hair strands. When the first cutting body 1 and the second cutting body 2 work together to cut, the hair strands slide from the end of the first cutting edge 12 into the bottom of the concave arc. Then, the arc-shaped sidewall on the other side of the concave arc limits the hair strands, stopping them from sliding. This ensures that the relative position remains stable during trimming. At the same time, the radius R1 of the concave arc and the width of the cutting edge can be set according to the trimming needs to achieve different trimming effects.
[0029] Between each pair of adjacent first blades 12, there is a second blade 13 in the shape of an arc. The second blade 13 is a convex arc with a radius of R2, where R2 = 0.25~1mm. The teeth 11 are generally ripple-shaped. During cutting, some hair strands will stay at the second blade 13 located between the two sets of first blades 12. The second blade 13 is set in the shape of a convex arc, and one end of the second blade 13 is connected to the end of one side of the first blade 12, and the other end is connected to the end of the other side of the first blade 12. The hair strands can smoothly slide into the first blade 12 after passing through the second blade 13, thereby improving the limiting ability of the first blade 12 on the hair strands and improving the hair styling effect of the anti-slip scissors.
[0030] The first cutting body 1 is thinner on one side near the second cutting body 2 and relatively thicker on the other side. The connecting surface of the thinner end and the thicker end forms the first cutting surface 14 and the second cutting surface 15. The connection between the first cutting surface 14 and the second cutting surface 15 forms an included angle α, which is in the range of 30° to 50°. The included angle α is preferably 40°, which can maintain the sharpness of the tooth 11, ensure the structural strength of the first cutting body 1, and effectively extend the service life of the anti-slip shear.
[0031] like Figure 1 , Figure 2 , Figure 7 As shown, the first handle 4 is cylindrical, and a first limiting boss 41 is formed at the connection between the first handle 4 and the first blade 1. A second limiting surface 52 is provided on the side wall of the second blade 2 near the second handle 5. The second blade 2 contacts or separates from the outer surface of the first limiting boss 41 through the second limiting surface 52. The cylindrical first handle 4 can better fit the fingertips, improving the stability of the first handle 4 rotating with the fingers. When the first blade 1 and the second blade 2 are closed, the first limiting boss 41 contacts the second limiting surface 52, keeping the positions of the first blade 1 and the second blade 2 relatively fixed, preventing the first blade 1 and the second blade 2 from rotating excessively, and improving the stability of the anti-slip shears when closed.
[0032] A first finger ring 43 is provided at one end of the first handle 4 opposite to the first blade 1. The first finger ring 43 is integrally formed with the first handle 4. A first support rod 44 for supporting the fingers is provided on the side of the first finger ring 43 opposite to the first handle 4. The fingers can be inserted into the first finger ring 43 and the finger pads can contact the inner wall of the first finger ring 43, preventing the first handle 4 from slipping off the fingers and improving the stability of the fingers driving the first handle 4 to rotate. This improves the stability of the first blade 1 during trimming. In addition, the first support rod 44 provided at the rear of the first finger ring 43 can support the little finger, reduce fatigue during long-term trimming, and improve the comfort of holding the anti-slip shears.
[0033] like Figure 1 , Figure 8 , Figure 9As shown, the second handle 5 is cylindrical, and a second limiting protrusion 51 is formed at the connection between the second handle 5 and the second blade 2. The first blade 1 has a first limiting surface 42 on its side wall near the first handle 4. The first blade 1 contacts or separates from the outer surface of the second limiting protrusion 51 through the first limiting surface 42. The second handle 5 is also cylindrical, allowing the barber to place their fingers against the first handle 4 or the second handle 5 as needed, thereby changing the direction of hair cutting. Furthermore, the second limiting protrusion 51 at the second handle 5 and the second blade 2 cooperates with the first limiting surface 42 on the first handle 4. The combination of the first limiting protrusion 41 on the first handle 4 and the second limiting surface 52 on the second handle 5 further improves the stability of the anti-slip shears when closed, preventing wobbling when the first blade 1 and the second blade 2 are closed.
[0034] The second handle 5 has a second finger ring 53 at one end opposite the second blade 2. The second finger ring 53 is integrally formed with the second handle 5. The second finger ring 53 has a second support bar 54 for supporting the fingers on the side opposite the second handle 5. The second finger ring 53, which is also provided on the second handle 5, together with the first finger ring 43, improves the barber's grip on the first handle 4 and the second handle 5 of the anti-slip scissors, effectively preventing the first handle 4 and the second handle 5 from falling. In addition, the second support bar 54 is also provided on the outside of the second finger ring 53, so that the barber can maintain a consistent grip posture when changing the grip direction according to the trimming needs, thus improving the consistency of the barber during trimming.
[0035] The working principle of this embodiment is as follows: the barber inserts his thumb into the first finger ring 43, his ring finger into the second finger ring 53, his index and middle fingers on the second handle 5, and his little finger on the first support rod 44. Then the barber drives the first handle 4 and the second handle 5 to move through his fingers, and the first blade 1 and the second blade 2 rotate around the pivot 3 to open.
[0036] The hair to be trimmed is then moved between the first blade 1 and the second blade 2. Then, the first handle 4 and the second handle 5 drive the first blade 1 and the second blade 2 to rotate in opposite directions to close the cutting. During the closing process, the hair that falls into the first blade 12 will be confined within the first blade 12, while the hair between the first blade 12 will be guided by the second blade 13 to slide into the first blade 12. The hair strands are confined by the concave arc sidewall of the first blade 12 and remain within the first blade 12. When the second blade 2 and the first blade 1 close, the hair strands can be cut, thus achieving the trimming of the hair.
[0037] It is important to note that barbers can adjust the grip of the non-slip scissors with their thumb and other fingers as needed for the trimming.
[0038] 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.
