Description

A pair of scissors with adjustable handle spacing Technical Field

[0001] This utility model belongs to the field of trimming tool technology, specifically relating to a pair of scissors with adjustable handle spacing. Background Technology

[0002] Scissors are everyday tools used for cutting objects. A typical pair of scissors consists of two blades that can be opened and closed, and two handles connected to the blades. The rear ends of the blades are connected by a pivot, and rotating the handles causes the blades to open and close. To use them, first rotate the blades to the open position, then place the object to be cut between the blades, and then operate the handles to bring the blades together to cut the object. It is a convenient tool to use.

[0003] However, existing scissor designs have shortcomings. The handles and blades are fixedly connected, making the distance between the handles unadjustable. Since every user has a different hand size, these scissors with a fixed handle spacing are only suitable for most users with average hand sizes. Users with larger or smaller hands will find the lack of adjustment uncomfortable and have to make do with what they have, resulting in significant discomfort when using the scissors. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pair of scissors with adjustable handle spacing. Using this pair of scissors, the distance between the two handles can be adjusted, so that it can be used by users with different hand sizes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pair of scissors with adjustable handle spacing, comprising two scissor blades and scissor handles respectively connected to the rear ends of the two scissor blades. Rotating the two scissor handles will cause the two scissor blades to rotate relative to each other and cut and separate. The rear ends of the two scissor blades are respectively provided with first connecting members, and the front ends of the two scissor handles are respectively provided with second connecting members. The two second connecting members are respectively rotatably connected to the first connecting members on the corresponding sides. The scissor handles can rotate around the first connecting members through their second connecting members, and a locking mechanism is provided between the second connecting members and the first connecting members to restrict the rotation of the second connecting members.

[0006] In the above solution, a first connecting member is provided at the rear end of the scissor blades, and the rear end of the scissor handles is rotatably connected to the first connecting member via a second connecting member. This allows the scissor handles to rotate around the first connecting member via the second connecting member, and the locking mechanism restricts the natural rotation of the two scissor handles. When it is necessary to adjust the distance between the two scissor handles, the locking mechanism can be released first, and then the two scissor handles can be turned in the direction of separation to increase the distance between them. Turning the two scissor handles in the direction of inclination will decrease the distance between them. In this way, the user can adjust the appropriate distance between the two scissor handles according to their hand size, making the scissors suitable for users with different hand sizes and more comfortable to operate. When it is not necessary to adjust the distance between the two scissor handles, the locking mechanism can be used to lock the two scissor handles, preventing them from rotating relative to the scissor blades. Thus, operating the two scissor handles will cause the two scissor blades to rotate and cut together and separate, without affecting the normal cutting use of the scissors.

[0007] Furthermore, the aforementioned shear blade has a connecting handle at its rear end. The first connecting member consists of two rotating posts respectively located on the upper and lower sides of the connecting handle. The second connecting member consists of two collars respectively located at the front end of the shear blade. The two collars are respectively fitted onto the outer side of the rotating posts on the corresponding sides, so that the shear blade can rotate around the rotating posts through their collars, thereby realizing the structural function of the shear blade being able to rotate relative to the shear blade.

[0008] Furthermore, the aforementioned connecting handle has a connecting ring at its rear end. Two rotating posts are slidably positioned inside the connecting ring at their upper and lower sides. An elastic element is located on the inner side of the connecting ring corresponding to the position between the two rotating posts. The locking mechanism includes several protrusions evenly distributed around the outer side of the rotating posts and several slots evenly distributed around the inner side of the collar. When the collar is rotated until the slots align with the protrusions, the elastic element pushes the two rotating posts outwards, causing the protrusions to insert into the slots. At this point, the protrusions, in conjunction with the slots, prevent the collar from rotating around the rotating posts, thus locking the scissor handle and preventing it from rotating relative to the scissor blades. Pressing the two rotating posts inwards to disengage the protrusions from the slots releases the lock. Without the protrusions obstructing the movement, the collar can then rotate around the rotating posts, allowing the two scissor handles to be rotated to adjust their distance.

[0009] Furthermore, two rotating posts located within the same connecting ring are arranged vertically opposite each other. A sliding groove is provided on the inner side of the connecting ring corresponding to the protrusion positions of the two rotating posts. The protrusions of the two rotating posts slide in the sliding groove of the connecting ring, thereby allowing the two rotating posts to slide up and down along the sliding groove of the connecting ring through their protrusions.

[0010] Furthermore, the aforementioned grooves extend vertically along the connecting ring, with the number of grooves being the same as the number of protrusions. The grooves penetrate the upper and lower side walls of the connecting ring, which facilitates the sliding of the two rotating pillars into and out of the upper and lower side openings of the grooves, making it convenient to assemble and disassemble the two rotating pillars and the connecting ring.

[0011] Furthermore, the aforementioned elastic element is a spring located on the inner side of the connecting ring between the two rotating pillars. The two ends of the spring abut against the inner sides of the two rotating pillars respectively. Without external force, the spring will push the two rotating pillars to slide outwards through its own elastic force.

[0012] Furthermore, the aforementioned scissor handle includes a wristband, a connecting post at the front end of the wristband, and a connecting block at the front end of the connecting post. The two sets of rings are respectively positioned opposite each other on the upper and lower sides of the connecting block, which facilitates the setting of the two sets of rings. The gripping part of the scissor handle is shaped like a wristband, which makes it easier for the user to pass their fingers through the wristband to grip the handle, resulting in a more secure grip.

[0013] Furthermore, the two aforementioned shear blades are connected to each other by a rotating shaft, so that the two shear blades can rotate around the shaft to cut and separate.

[0014] Furthermore, the aforementioned rotating shaft includes a shaft pin and a shaft washer. The outer end of the shaft pin is provided with a shaft cap. The shaft pin passes through the rear sidewall of the two shear blades and connects with the shaft washer. This facilitates the disassembly and assembly of the shears. The shaft cap and shaft washer can prevent the two shear blades from shifting in the direction of mutual separation, making the rotation structure of the two shear blades more stable and ensuring the installation stability of the two shear blades.

[0015] Furthermore, clearance grooves are provided on the outer sides of the two aforementioned shear blades corresponding to the positions of the shaft cap and shaft pad, and the shaft cap and shaft pad are respectively placed in the clearance grooves on the corresponding sides, so that the shaft cap and shaft pad will not protrude from the outer side of the shear blade, making the structure of the scissors more compact.

[0016] This utility model's scissors feature two handles that can rotate relative to the blades, allowing adjustment of the distance between the handles. This makes them suitable for users with various hand sizes, providing greater comfort. When the handle spacing is not needed, a locking mechanism locks the handles in place, ensuring uninterrupted cutting operation. Locking and unlocking are simple and convenient. To adjust the handle spacing, simply press the protrusions on the two rotating posts to disengage them from the locking slots, releasing the lock and allowing the handles to rotate for adjustment. Releasing the rotating posts causes the springs to automatically push the protrusions into the locking slots, locking the handles and preventing rotation relative to the blades, ensuring structural stability.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0028] Example 1

[0029] As shown in Figure 1, this embodiment provides a pair of scissors with adjustable handle spacing, including two scissor blades 1 and scissor handles 2 respectively connected to the rear ends of the two scissor blades 1. Rotating the two scissor handles 2 will cause the two scissor blades 1 to rotate relative to each other and cut and separate. The rear ends of the two scissor blades 1 are respectively provided with first connecting members, and the front ends of the two scissor handles 2 are respectively provided with second connecting members. The two second connecting members are rotatably connected to the first connecting members on the corresponding sides. The scissor handles 2 can rotate around the first connecting members through their second connecting members, and a locking mechanism that can restrict the rotation of the second connecting members is provided between the second connecting members and the first connecting members.

[0030] Specifically, as shown in Figures 1 and 3, the two aforementioned scissor blades 1 are respectively provided with connecting handles 11 at their rear ends. The first connecting member consists of two rotating posts 12 respectively located on the upper and lower sides of the rear end of the connecting handles 11. The second connecting member consists of two collars 21 respectively located at the front end of the scissor handles 2. The two collars 21 are respectively fitted onto the outer side of the rotating posts 12 on the corresponding side, and the two collars 21 are respectively located on the upper and lower sides of the connecting ring 13, so that the scissor handles 2 can rotate around the rotating posts 12 through their collars 21, thereby realizing the structural function that the scissor handles 2 can rotate relative to the scissor blades 1. In this way, the distance between the two scissor handles 2 can be adjusted by rotating the two scissor handles 2, so that the user can adjust the appropriate distance between the two scissor handles 2 according to their own hand size.

[0031] When using the scissors in this embodiment, if it is necessary to adjust the distance between the two handles 2, the locking mechanism can be released first, and then the two handles 2 can be rotated in the direction of separation to increase the distance between the two handles 2, making it suitable for users with larger hands to grip and use; while rotating the two handles 2 in the direction of inclination will decrease the distance between the two handles 2, making it suitable for users with smaller hands to grip and use. Thus, the user can adjust the appropriate distance between the two handles 2 according to their own hand size, making the grip and operation more comfortable.

[0032] When there is no need to adjust the distance between the two shear handles 2, the user can lock the two shear handles 2 using the locking mechanism, preventing them from rotating relative to the shear blades 1. Operating the two shear handles 2 will then cause the two shear blades 1 to rotate and separate, without affecting the normal cutting function of the scissors. When it is necessary to cut an item, as shown in Figure 3, the two shear handles 2 can be operated to rotate and separate the two shear blades 1. Then, the item to be cut can be placed between the two shear blades 1, as shown in Figure 4. Then, the two shear handles 2 can be operated again to rotate and close the two shear blades 1, thus completing the cutting operation. The operation is convenient.

[0033] In this embodiment, the spacing between the two handles 2 of the scissors is adjustable, making it suitable for users with different hand sizes to grip and use, and more comfortable to operate.

[0034] Example 2

[0035] This embodiment is a further improvement on the structure of the adjustable handle spacing scissors of Embodiment 1. The improvement is that, as shown in Figures 1 and 2, the rear end of the connecting handle 11 is provided with a connecting ring 13, and the two rotating posts 12 are respectively slidably disposed inside the upper and lower sides of the connecting ring 13. An elastic element 4 is provided on the inner side of the connecting ring 13 corresponding to the position between the two rotating posts 12. The locking mechanism includes a number of protrusions 121 evenly distributed on the outer side of the rotating posts 12 and a number of latching grooves 211 evenly distributed on the inner side of the collar 21. The number of protrusions 121 is the same as the number of latching grooves 211.

[0036] As shown in Figures 4 and 5, when the collar 21 is rotated until the groove 211 and the protrusion 121 are aligned, the elastic element 4 pushes the two rotating posts 12 to slide outwards, causing the protrusion 121 to insert into the groove 211. At this time, with the cooperation of the groove 211 and the protrusion 121, the protrusion 121 prevents the collar 21 from rotating around the rotating post 12, thus locking the scissor handle 2 and preventing it from rotating relative to the scissor blade 1. Therefore, the distance between the two scissor handles 2 cannot be adjusted. However, as shown in Figure 6, when the two rotating posts 12 are pressed and slid inwards, causing the protrusion 121 to disengage from the groove 211 of the collar 21, the lock is released. At this time, without the obstruction of the protrusion 121, the collar 21 can rotate around the rotating post 12, allowing the two scissor handles 2 to be rotated to adjust the distance between them.

[0037] Specifically, as shown in Figures 1 and 2, the two rotating posts 12 located within the same connecting ring 13 are arranged vertically opposite each other. A groove 131 is provided on the inner side of the connecting ring 13 corresponding to the protrusions 121 of the two rotating posts 12. The protrusions 121 of the two rotating posts 12 slide within the groove of the connecting ring 13, allowing the two rotating posts 12 to slide up and down along the groove 131 of the connecting ring 13 via their protrusions 121. The groove 131 extends vertically along the connecting ring 13, and the number of grooves 131 is the same as the number of protrusions 121. The grooves 131 penetrate the upper and lower sidewalls of the connecting ring 13, facilitating the sliding and disassembly of the two rotating posts 12 from the upper and lower openings of the groove 131, respectively.

[0038] Example 3

[0039] This embodiment is a further improvement on the adjustable handle spacing scissor structure of Embodiment 2. The improvement is that, as shown in Figures 1 and 5, the elastic element 4 is a spring located inside the connecting ring 13 between the two rotating posts 12. The upper end of the spring abuts against the inner side of the rotating post 12 located on the upper side, and the lower end of the spring abuts against the inner side of the rotating post 12 located on the lower side. Without external force, the spring will push the two rotating posts 12 to slide outwards through its own elastic force.

[0040] As shown in Figure 1, the aforementioned shear handle 2 includes a wristband 22, a connecting post 23 located at the front end of the wristband 22, and a connecting block 24 located at the front end of the connecting post 23. Two sets of rings 21 are respectively positioned opposite each other on the upper and lower sides of the connecting block 24, which facilitates the installation of the two sets of rings 21. The gripping part of the shear handle 2 is shaped like the wristband 22, which allows the user to easily pass their fingers through the wristband 22 for gripping, resulting in a more secure grip on the shear handle. The aforementioned rings 21, wristband 22, connecting post 23, and connecting block 24 are an integral structure, as are the shear blade 1, connecting handle 11, and connecting ring 13, to ensure the stability of the connection between the various components of the shear blade and shear handle 2.

[0041] Specifically, the rear ends of the two aforementioned shear blades 1 are rotatably connected to each other via a pivot, allowing the two shear blades 1 to rotate around the pivot for cutting and separating. The pivot includes a pivot pin 31 and a pivot washer 32. The outer end of the pivot pin 31 is provided with a pivot cap 311. The pivot pin 31 passes through the rear end sidewalls of the two shear blades 1 and connects to the pivot washer 32. This facilitates the assembly and disassembly of the shears, and the pivot cap 311 and pivot washer 32 prevent the two shear blades 1 from shifting in the direction of separation, making the rotation structure of the two shear blades more stable and ensuring the installation stability of the two shear blades 1.

[0042] In addition, clearance grooves 10 are respectively provided on the outer sides of the two aforementioned shear blades 1 at the positions corresponding to the shaft caps 311 and shaft pads 32. The shaft caps 311 and shaft pads 32 are respectively placed in the clearance grooves 10 on the corresponding sides so that the shaft caps 311 and shaft pads 32 will not protrude from the outer side of the shear blades 1, making the structure of the scissors more compact.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
