Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, specifically relating to a pair of scissors. Background Technology

[0002] Scissors are a type of manual cutting tool primarily used for cutting objects. A typical scissor structure includes a first blade, a second blade, a first handle connected to the rear end of the first blade, and a second handle connected to the rear end of the second blade. The first and second blades are hinged together at the rear ends by rivets, allowing the blades to rotate around the rivets to cut and separate. In use, the blades are separated by holding the handles, the object to be cut is placed between the blades, and then the blades are moved to cut. The operation is convenient.

[0003] However, the aforementioned scissors still have shortcomings. Because the two blades of the scissors are stacked on top of each other, and the two blades are hinged together by rivets, they cannot be disassembled. This makes it inconvenient to clean the stacked blades. In addition, each blade has a cutting edge on its opposite side. If the two blades could be disassembled and separated, one of the blades could be used as a knife to cut objects, making it more versatile. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pair of scissors whose two blades can be disassembled and separated.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pair of scissors, including a first and a second scissor blade that can rotate and cut and separate from each other, a first scissor handle connected to the rear end of the first scissor blade, and a second scissor handle connected to the rear end of the second scissor blade. The first scissor blade has a slot with an annular groove inside. The second scissor blade has a top-opening insert seat with the opening penetrating the upper side of the second scissor blade. The insert seat can be inserted into the slot and rotate relative to the slot. The insert seat contains a sliding post, an elastic element, and a ball. A through hole is provided on the side wall of the insert seat corresponding to the lower position of the second scissor blade. The ball is located in the through hole. The sliding post is slidably disposed in the insert seat. A clearance groove is provided on the outer side of the sliding post corresponding to the position of the ball. When the insert seat is inserted into the slot and the through hole and the annular groove are aligned, the elastic element will push the sliding post upward, causing the side wall of the sliding post to push the ball out of the through hole and into the annular groove. When the sliding post is pressed downward until the clearance groove and the ball are aligned, the ball can be inserted into the clearance groove and disengaged from the annular groove.

[0006] In the above solution, a slot is provided in the first shear blade. When the insert pin is inserted into the slot and the through hole is aligned with the annular groove, the elastic element, in its natural state, will push the sliding pin upward through its own elastic force. This causes the side wall of the sliding pin to push the ball out of the through hole and into the annular groove of the slot, thus assembling the two shear blades. The ball can then slide along the annular groove without interfering with the rotation of the insert pin within the slot, allowing the two shear blades to rotate and separate. With the annular groove structure, regardless of the angle to which the two shear blades rotate, as long as the insert pin is inserted into the slot and the through hole is aligned with the annular groove, the ball will engage, making assembly and disassembly more convenient. Furthermore, in the assembled state, regardless of the angle to which the two shear blades rotate, the annular groove prevents the ball from moving up and down, thus preventing the insert pin from detaching from the slot and ensuring the stability of the assembly. This prevents the two shear blades from accidentally detaching during cutting, making it more convenient and safer to use. When it is necessary to disassemble the two shear blades, slide the sliding pin downwards until the clearance groove and the ball are aligned. Then, operate the second shear blade to move the insert seat upwards and disengage it from the slot. (With the clearance groove and the ball aligned, the clearance groove can make room for the ball. When the ball is pressed by the upper side wall of the annular groove, it will move towards the clearance groove, causing the ball to get into the clearance groove and disengage from the annular groove. At this time, the annular groove can no longer block the ball from moving upwards, allowing the insert seat to move upwards and disengage from the slot.) This allows the two shear blades to be disassembled and separated. This makes it easy to thoroughly clean both shear blades, making cleaning more convenient and thorough. One of the shear blades can also be used as a knife for cutting items, making its uses more versatile.

[0007] Furthermore, the aforementioned through holes are provided in a number of them, which are evenly distributed along the circumference of the insert base. The number of pins is equal to the number of through holes, and each pin is placed in its corresponding through hole. This scheme, through the cooperation of multiple pins with the annular groove, can better prevent the insert base from coming out of the slot, thereby improving the assembly stability of the two shear plates.

[0008] Furthermore, when the aforementioned insert base is inserted into the slot and the through hole and annular groove are aligned, the elastic element will push the sliding pin upward, causing the ball to engage in the annular groove. At this point, the two shear blades are in an assembled state, with the upper side of the first shear blade and the lower side of the second shear blade fitting together. This optimizes the cutting effect of the first and second shear blades. Additionally, after the two shear blades are fitted together, the insert base can no longer move towards the first shear blade, thus positioning the insert base at the alignment point between the through hole and the annular groove. This allows the ball to engage more precisely in the annular groove.

[0009] Furthermore, the upper end of the aforementioned sliding column is provided with a column cap, which extends out of the opening of the insert seat. This allows the sliding column to slide downwards by pressing the column cap, making it easier to disassemble the two shear blades.

[0010] Furthermore, the aforementioned elastic element is a spring located inside the insert seat corresponding to the lower side of the sliding column. A spring groove is provided on the lower end face of the sliding column, and the upper end of the spring is placed in the spring groove and abuts against the bottom of the spring groove. This can improve the installation stability of the spring. The lower end of the spring abuts against the bottom of the inner side of the insert seat. In its natural state, the spring will push the sliding column upward through its own elastic force.

[0011] Furthermore, the first shear blade has a first mounting hole at its rear end, and a retaining ring is installed in the first mounting hole. The hollow part of the retaining ring forms a slot, and an annular groove is opened on the inner side of the hollow part of the retaining ring, which facilitates the setting of the slot and the annular groove.

[0012] Furthermore, the upper inner side of the aforementioned first mounting hole is provided with a first limiting groove, and the outer side of the upper end of the buckle is provided with a first protruding ring. The buckle is inserted into the first mounting hole, and the first protruding ring cooperates with the first limiting groove. The first limiting groove can prevent the first protruding ring from moving downward, thereby preventing the buckle from moving downward along the first mounting hole. The lower end of the buckle extends out of the first mounting hole, and a first fixing ring is threadedly connected to the outer side of the lower end of the buckle. The upper side of the first fixing ring abuts against the lower side of the first shear plate. The first fixing ring can prevent the buckle from moving upward along the first mounting hole, thereby ensuring the installation stability of the buckle. By twisting the first fixing ring to disengage from the buckle, the buckle can be moved upward and disengaged from the first mounting hole, making disassembly and assembly convenient.

[0013] Furthermore, the second shear blade has a second mounting hole at its rear end, a second limiting groove at the lower inner end of the second mounting hole, and a second protruding ring on the outer side of the insert base. The insert base is inserted into the second mounting hole, and the second protruding ring engages with the second limiting groove. The upper end of the insert base extends out of the second mounting hole, and a second fixing ring is threadedly connected to the outer side of the upper end of the insert base. The lower side of the second fixing ring abuts against the upper side of the second shear blade. In this design, the second limiting groove prevents the second protruding ring of the insert base from moving upward, while the second fixing ring prevents the insert base from moving downward, thus preventing the insert base from moving up and down along the second mounting hole and ensuring the installation stability of the insert base. By unscrewing the second fixing ring from the insert base, the insert base can be moved downward and disengaged from the second mounting hole.

[0014] Furthermore, both the first and second mounting holes are non-circular structures. The outer side of the buckle mates with the inner side of the first mounting hole, which prevents the buckle from rotating within the first mounting hole. Similarly, the outer side of the insert seat mates with the inner side of the second mounting hole, which prevents the insert seat from rotating within the second mounting hole, thereby further improving the installation stability of the buckle and the insert seat.

[0015] Furthermore, the first scissor blade has a bottle-opening notch on its side wall, which can be used to open the bottle cap, thus increasing the functionality of the scissors.

[0016] The two blades of this scissors can be disassembled and separated, allowing for easy and thorough cleaning. One blade can also be used as a cutting tool, and the first blade has a bottle-opening notch for opening bottle caps, making it more versatile. The annular groove structure ensures that regardless of the blades' rotation angle, the insert pin can be inserted into and released from the groove as long as the through hole aligns with the annular groove. This makes assembling and disassembling the blades much easier. Furthermore, in the assembled state, the annular groove prevents the insert pin from moving up and down, ensuring the stability of the blades and preventing accidental detachment during cutting. This enhances both convenience and safety. In addition, the assembly and disassembly of the two shear blades is very simple. When using them, simply press the cap and insert the insert into the slot until the two shear blades are in contact. Then release the cap to allow the ball to insert into the annular groove to complete the assembly of the two shear blades. Press the cap again and move the insert upward to disengage it from the slot to complete the disassembly of the two shear blades. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0027] Example 1

[0028] like Figure 1-4 As shown, this embodiment provides a pair of scissors, including a first scissor blade 1 and a second scissor blade 2 that can rotate and cut and separate from each other, a first scissor handle connected to the rear end of the first scissor blade 1, and a second scissor handle 21 connected to the rear end of the second scissor blade 2. The upper side of the rear end of the first scissor blade 1 is provided with a slot 10, and the inner side of the slot 10 is provided with an annular groove 101. The lower side of the rear end of the second scissor blade 2 is provided with a top-opening insert seat 22, and the opening of the insert seat 22 penetrates the upper side of the second scissor blade 2. The inner side of the slot 10 is a circular groove structure that matches the outer side of the insert seat 22, so that the insert seat 22 can be inserted into the slot 10 and rotate relative to the slot 10.

[0029] The aforementioned insert base 22 is provided with a sliding post 221, an elastic element 222 and a ball 223. A through hole 220 is provided on the side wall of the insert base 22 corresponding to the position below the second shear piece 2. The ball 223 is located in the through hole 220. The sliding post 221 is slidably disposed in the insert base 22 and can slide up and down along the insert base 22. An avoidance groove 2211 is provided on the outer side of the sliding post 221 corresponding to the position of the ball 223.

[0030] like Figure 3As shown, when the insert pin 22 is inserted into the slot 10 and the through hole 220 is aligned with the annular groove 101, the elastic element 222, in its natural state, will push the sliding pin 221 upward through its own elastic force. This causes the side wall of the sliding pin 221 to push the ball 223 out of the through hole 220 and into the annular groove 101, thus assembling the two shear pieces. At this time, the ball 223 can slide along the annular groove 101, thus not interfering with the rotation of the insert pin 22 within the slot 10, allowing the two shear pieces to rotate and shear and separate. Meanwhile, the ball 223 cannot move up or down due to the obstruction of the annular groove 101, thereby preventing the insert pin 22 from dislodging upward from the slot 10 and ensuring the stability of the assembly of the two shear pieces.

[0031] like Figure 4 As shown, when the slide bar 221 is pressed down and slids down until the clearance groove 2211 is aligned with the ball 223, the clearance groove 2211 of the slide bar 221 can make room for the ball 223. At this time, when the insert seat 22 is moved upward, the ball 223 will move towards the clearance groove 2211 due to the pressure of the upper side wall of the annular groove 101. This allows the ball 223 to be inserted into the clearance groove 2211 and disengage from the annular groove 101. At this time, the insert seat 22 can be disengaged from the slot, thereby allowing the two shears to be disassembled and separated.

[0032] When using the scissors in this embodiment, to assemble two scissor blades, first slide the sliding pin 221 downwards until the clearance groove 2211 and the ball bearing 223 are aligned. Then, insert the insert base 22 into the slot 10, aligning the through hole 220 with the annular groove 101. Release the sliding pin 221, and the elastic element 222 will automatically push the sliding pin 221 upwards, causing the ball bearing 223 to engage in the annular groove 101, thus completing the assembly of the two scissor blades. Figure 2 , 3 As shown.

[0033] When it is necessary to disassemble the two shear blades, the sliding pin 221 can be pressed down again until the clearance groove 2211 and the ball 223 are aligned (at this time, the ball 223 can be inserted into the clearance groove 2211 and disengaged from the annular groove 101). Then, the insert base 22 can be moved upward to disengage from the slot 10, thus completing the assembly of the two shear blades. Figure 1 , 4 As shown.

[0034] like Figure 2 As shown, the first scissor 1 has a bottle-opening notch 5 on its side wall, which can be used to open bottle caps, increasing the functionality of the scissors. Furthermore, when the two scissors are disassembled, using the first scissor 1 alone provides greater flexibility in opening bottle caps.

[0035] The scissors in this embodiment can not only be used for cutting items, but the two blades can also be disassembled for easy and thorough cleaning, making cleaning more convenient and hygienic. Furthermore, after disassembling the two blades, one of them can be used as a knife to cut items, making its uses more versatile.

[0036] Example 2

[0037] This embodiment is a further improvement on the scissor structure of Embodiment 1. The improvement lies in that, as... Figure 5 As shown, four through holes 220 are provided, and the four through holes are evenly distributed along the circumference of the insert base 22. The number of pins 223 is equal to the number of through holes 220. Each pin 223 is placed in the corresponding through hole 220. This scheme uses the four pins to cooperate with the annular groove 101, which can better prevent the insert base 22 from coming out of the slot 10, thereby improving the assembly stability of the two shear pieces.

[0038] like Figure 3 , 4 As shown, when the aforementioned insert base 22 is inserted into the slot 10 and the through hole 220 is aligned with the annular groove 101, the elastic element 222 will push the sliding pin 221 upward, causing the ball 223 to be engaged in the annular groove 101. At this time, the two shear blades are in an assembled state, and the upper side of the first shear blade 1 and the lower side of the second shear blade 2 are in contact with each other, thus achieving the best cutting effect between the first shear blade 1 and the second shear blade 2. In addition, after the two shear blades are in contact with each other, the insert base 22 can no longer move downward, thus positioning the insert base 22 at the alignment position of the through hole 220 and the annular groove 101, allowing the ball 223 to be engaged in the annular groove 101 more accurately.

[0039] In addition, the upper end of the sliding column 221 is provided with a column cap 2212, which extends out of the opening of the insert seat 22. This allows the sliding column 221 to slide downward by pressing the column cap 2212, making it easier to disassemble the two shear blades.

[0040] Specifically, the aforementioned elastic element 222 is a spring located inside the insert seat 22 corresponding to the lower side of the sliding post 221. The lower end face of the sliding post 221 has a spring groove 2210. The upper end of the spring is placed inside the spring groove 2210 and abuts against the bottom of the spring groove 2210. This can improve the installation stability of the spring. The lower end of the spring abuts against the bottom of the inner side of the insert seat 22. In its natural state, the spring will push the sliding post 221 upward through its own elastic force.

[0041] Example 3

[0042] This embodiment is a further improvement on the scissor structure of Embodiment 2. The improvement lies in that, as Figure 5 ,6 As shown, the first shear blade 1 has a first mounting hole 13 at its rear end. A retaining ring 3 is installed in the first mounting hole 13. The hollow part of the retaining ring 3 forms a slot 10, and an annular groove 101 is formed on the inner side of the hollow part of the retaining ring 3. The upper inner side of the first mounting hole 13 has a first limiting groove 131, and the outer side of the upper end of the retaining ring 3 has a first protruding ring 31. The retaining ring 3 is inserted into the first mounting hole 13, and the first protruding ring 31 cooperates with the first limiting groove 131. The first limiting groove 131 can prevent the first protruding ring 31 from moving downward, thereby preventing the retaining ring 3 from moving downward along the first mounting hole 13. The lower end of the retaining ring 3 extends out of the first mounting hole 13, and a first fixing ring 41 is threadedly connected to the outer side of the lower end of the retaining ring 3. The upper side of the first fixing ring 41 abuts against the lower side of the first shear blade 1. The first fixing ring 41 can prevent the retaining ring 3 from moving upward along the first mounting hole 13, thereby ensuring the installation stability of the retaining ring 3. By twisting the first fixing ring 41 to disengage from the buckle 3, the buckle can be moved upward to disengage from the first mounting hole 13, making disassembly and assembly convenient.

[0043] like Figure 5 , 7 As shown, the second shear blade 2 has a second mounting hole 23 at its rear end. A second limiting groove 231 is provided at the lower inner end of the second mounting hole 23. A second protruding ring 224 is provided on the outer side of the insertion base 22. The insertion base 22 is inserted into the second mounting hole 23, and the second protruding ring 224 engages with the second limiting groove 231. The upper end of the insertion base 22 extends out of the second mounting hole 23, and a second fixing ring 42 is threadedly connected to the outer upper end of the insertion base 22. The lower side of the second fixing ring 42 abuts against the upper side of the second shear blade 2. In this design, the second limiting groove 231 prevents the second protruding ring 224 of the insertion base 22 from moving upwards, while the second fixing ring 42 prevents the insertion base 22 from moving downwards, thus preventing the insertion base 22 from moving up and down along the second mounting hole 23 and ensuring the installation stability of the insertion base 22. Tightening the second fixing ring 42 disengages the insertion base 22, allowing it to move downwards and disengage from the second mounting hole 23.

[0044] Specifically, both the first mounting hole 13 and the second mounting hole 23 are non-circular hole structures. The outer side of the retaining ring 3 mates with the inner side of the first mounting hole 13, which prevents the retaining ring 3 from rotating along the first mounting hole 13. Similarly, the outer side of the insert seat 22 mates with the inner side of the second mounting hole 23, which prevents the insert seat 22 from rotating along the second mounting hole 23, thereby further improving the installation stability of the retaining ring 3 and the insert seat 22.

[0045] 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.
