[0030] like Figure 1-5 As shown, the utility model provides a detachable scissors, the scissors comprising:
[0031] A first scissors body 100, comprising a first handle 110 and a first blade 120, wherein the first blade 120 is provided with a limit buckle 121 and a protrusion 125;
[0032] The second scissors body 200 includes a second handle 210 and a second blade 220. The second blade 220 is provided with an assembly hole 221. The protrusion 125 and the assembly hole 221 are detachably connected. The protrusion 125 is rotatably connected to the assembly hole 221 so that the protrusion 125 and the assembly hole 221 are separated or fixed. The limiting buckle 121 is located between the first handle 110 and the second blade 220. One end of the limiting buckle 121 contacts the second blade 220. The limiting buckle 121 is used to limit the second blade 220.
[0033] In the embodiment of the present invention, a limit buckle 121 is provided on the first scissors body 100, and the limit buckle 121 is connected to the first blade 120, and the limit buckle 121 contacts the second blade 220. When the detachable scissors are used, the limit buckle 121 will restrict the movement of the second blade 220, effectively preventing the detachable scissors from being separated from the first scissors body 100 and the second scissors body 200 due to an excessively large opening angle, thereby avoiding the risk of the detachable scissors accidentally falling during use; at the same time, the limit buckle 121 will move under the action of a larger rotational thrust, and after the limit buckle 121 is subjected to a larger rotational thrust, the limiting effect of the limit buckle 121 on the second blade 220 becomes invalid, and the user can disassemble the detachable scissors, which enables the user to subjectively choose whether to disassemble the detachable scissors, thereby increasing the flexibility and safety of the detachable scissors.
[0034] like Figure 1-5 As shown, in an optional embodiment of the present utility model, the limit buckle includes a limit slot, a connecting piece, and a limit buckle body. The connecting piece is located inside the limit slot, one end of the connecting piece passes through the limit slot and is connected to the first blade, and the limit buckle body is movably connected to the connecting piece along the limit slot.
[0035] Among them, the first scissors body 100 and the second scissors body 200 are combined together to form a detachable scissors. The first scissors body 100 and the second scissors body 200 are connected by the protrusion 125 and the assembly hole 221. When the detachable scissors are working, the first scissors body 100 and the second scissors body 200 rotate around the protrusion 125 and the assembly hole 221. The protrusion 125 is connected to the assembly hole 221 so that the first scissors body 100 and the second scissors body 200 are fixed or separated. , the shapes of the protrusion 125 and the assembly hole 221 are set. When the angle between the first scissors body 100 and the second scissors body 200 is too large, the shape of the protrusion 125 is adapted to the shape of the assembly hole 221, and the protrusion 125 and the assembly hole 221 can be separated. When the angle between the first scissors body 100 and the second scissors body 200 is small, the shape of the protrusion 125 and the shape of the assembly hole 221 are stuck to each other, so that the first scissors body 100 and the second scissors body 200 are fixed. The function of the connecting piece 123 is to connect the limit buckle body 124 with the first scissors body 100. The limit buckle body 124 can limit the movement of the second scissors body 200 when the first scissors body 100 and the second scissors body 200 rotate, so that the angle between the second scissors body 200 and the first scissors body 100 cannot be opened to the angle at which the protrusion 125 is separated from the assembly hole 221. The force of the limit buckle body 124 to limit the second scissors body 200 is provided by the friction between the connecting piece 123 and the limit slot 122. When the thrust applied by the second scissors body 200 to the limit buckle body 124 is greater than the friction between the connecting piece 123 and the limit slot 122, the limit buckle body 124 moves along the limit slot 122.
[0036] Specifically, the working process of the detachable scissors is as follows: when the detachable scissors need to be disassembled, the user uses the protrusion 125 as the axis, grasps the first handle 110 and the second handle 210 to expand the angle between the first handle 110 and the second handle 210 outward, and the rotation lever thrust generated by the contact position between the second blade 220 and the limiting buckle 121 causes the limiting buckle 121 to move along the limiting slot 122 toward the direction in which the second blade 220 applies force to the limiting buckle body 124. When the limiting buckle body 124 moves, the limiting buckle body 124 cannot limit the rotation angle of the protrusion 125 of the second blade 220. At this time, the protrusion 125 and the assembly hole 221 reach a separable angle, thereby disassembling the first blade 120 and the second blade 220. Disassembly; when reassembling the first blade 120 and the second blade 220, the raised portion 125 of the first scissors body 100 is aligned with the assembly hole 221 of the second scissors body 200. The user takes the raised portion 125 as the axis, grasps the first handle 110 and the second handle 210 and closes them inward, and the rotational thrust of the first handle 110 and the second handle 210 on the limiting buckle body 124 causes the limiting buckle body 124 to move along the limiting slot 122 so that one end of the limiting buckle body 124 contacts the second blade 220. At this time, the limiting buckle body 124 can limit the second blade 220. When the user operates, the opening angle of the disassembled scissors will be limited to a range so that the scissors will not be suddenly in a separated state, thereby preventing the scissors from falling.
[0037] In the embodiment of the present invention, a limit buckle 121 is provided on the first scissors body 100, and the limit buckle 121 is connected to the first blade 120. The limit buckle body 124 in the limit buckle 121 contacts the second blade 220. When the detachable scissors are used, friction is generated due to the interaction between the limit slot 122 and the connecting member 123 in the limit buckle 121. The friction force applied to the limit buckle 121 will limit the movement of the second blade 220, effectively preventing the detachable scissors from being opened due to the angle The problem of the first scissors body 100 and the second scissors body 200 being separated due to being too large is avoided, and the risk of the detachable scissors accidentally falling during use is avoided; at the same time, the limit buckle 121 will move along the limit slot 122 under the action of a large rotational thrust. After the limit buckle 121 is subjected to a large rotational thrust, the limiting effect of the limit buckle 121 on the second blade 220 becomes invalid, and the user can disassemble the detachable scissors. This allows the user to subjectively choose whether to disassemble the detachable scissors, thereby increasing the flexibility and safety of the detachable scissors.
[0038] In an optional embodiment of the present invention, the connecting member 123 is a pin, the protrusion 125 includes a nut and a screw, the top of the screw is located on the top side of the assembly hole 221, the screw passes through the assembly hole 221, and the nut is located at the bottom of the screw.
[0039] Among them, the pin is a common connecting element, which is usually used to fix two or more parts together. Connecting the limit buckle 121 and the first blade 120 together through the pin can enhance the stability of the limit buckle 121 and the first blade 120, ensuring that the limit body can stably follow the movement of the first scissors body 100. Due to the stable characteristics of the pin, the friction generated by the interaction between the pin and the limit slot 122 is greater. The greater friction can ensure that the limit buckle body 124 will not fail when limiting the rotation of the second scissors body 200, reducing the risk of accidental separation of the detachable scissors due to insufficient friction causing the movement of the second scissors body 200 to be unrestricted.
[0040] like Figure 1-3 As shown, in an optional embodiment of the present invention, the raised portion 125 includes a raised top and a raised bottom, the raised portion 125 passes through the assembly hole, the raised top is located on the top side of the assembly hole 221, the shape of the raised top corresponds to the shape of the assembly hole 221, and the shapes of the raised top and the assembly hole 224 are not circular.
[0041] The shape of the top of the protrusion 125 corresponds to the shape of the assembly hole 221, which means that the shape of the top of the protrusion 125 and the shape of the assembly hole 221 can adapt to each other. For example, if the shape of the top of the protrusion is rectangular, the shape of the assembly hole 221 should also be rectangular; if the shape of the top of the protrusion 125 is triangular, the shape of the assembly hole 221 should also be triangular; if the shape of the top of the protrusion 125 is inconsistent with the shape of the assembly hole 221, the first scissors body 100 and the second scissors body 200 cannot be combined. Figure 1 The shape of the assembly body and the shape of the top of the protrusion 125 are both rectangular. When the user assembles the detachable scissors, he only needs to align them with each other. When using the detachable scissors, due to the mutual rotation of the first scissors body 100 and the second scissors body 200, the separation angle between the protrusion top and the assembly hole 221 changes, thereby fixing them to each other.
[0042] In the embodiment of the present invention, the rotatable and detachable connection between the first scissors body 100 and the second scissors body 200 is achieved through the shape correspondence between the protrusion 125 and the assembly hole 221. This design ensures the normal use of the detachable scissors.
[0043] In an optional embodiment of the present invention, the limiting slot 122 is annular, and the apertures at both ends of the limiting slot 122 are larger than the aperture in the middle of the limiting slot 122 .
[0044] The two ends of the limit slot 122 are the locking and unlocking fixed positions of the detachable scissors. When the pin is in the locked fixed position, the detachable scissors are in the locked state; when the pin is in the unlocked fixed position, the detachable scissors are in the unlocked state. This design of large apertures at both ends and narrow in the middle is designed to take into account the detachable scissors in the locked and unlocked states (the pin is in the locked and unlocked fixed positions, and the slot is wider). This design allows the limit slot 122 and the pin to be in a relaxed state when interacting with each other, so that the pin cannot expand the limit slot 122 for a long time, thereby preventing the limit slot 122 from being in a state of plastic deformation and fatigue. The width of the narrow part in the middle of the limiting slot 122 is designed to be slightly smaller than the axial diameter of the connecting member 123. In this way, when the connecting member 123 passes through the narrow part in the middle of the limiting slot 122, it needs to overcome a certain resistance. This resistance comes from the friction generated by the connecting member 123 and the narrow part in the middle of the limiting slot 122. The magnitude of the friction is achieved by the middle annular wall of the limiting slot 122 and the outer wall of the connecting member 123. When the width of the middle annular wall of the limiting slot 122 is smaller, the friction between the limiting slot 122 and the connecting member 123 is greater. When the width of the middle annular wall of the limiting slot 122 is larger, the friction between the limiting slot 122 and the connecting member 123 is smaller. When the detachable scissors are in use, the connecting piece 123 is located in the locked fixed position of the limiting slot 122. At this time, the width of the narrow middle part of the limiting slot 122 is small (smaller than the shaft diameter of the connecting piece 123), which can provide greater friction and effectively limit the second blade 220. When the detachable scissors are disassembled, the connecting piece 123 is located in the unlocked fixed position of the limiting slot 122, and the second blade 220 does not need to be limited at this time. When the detachable scissors are in the disassembled state, the connecting piece 123 is in the limiting fixed position. The locking clasp 121 is in the unlocked fixed position of the limiting slot 122. Similarly, the friction force of the narrow middle position of the limiting slot 122 can prevent the limiting buckle 121 from moving to the other end, thereby ensuring that the limiting buckle 121 is in the unlocked state. When the detachable scissors need to reassemble the first scissors body 100 and the second scissors body 200, the limiting buckle 121 is pushed back to the locked fixed position of the limiting slot 122 through the rotating lever thrust when the second scissors body 200 is closed, thereby re-producing the limiting effect on the second blade 220.
[0045] In the embodiment of the present invention, the limiting slot 122 is annular, and the apertures at both ends of the limiting slot 122 are larger than the aperture in the middle of the limiting slot 122 , thereby enhancing the durability of the detachable scissors.
[0046] In an optional embodiment of the present invention, the material of the limiting buckle 121 is wear-resistant plastic.
[0047] Among them, wear-resistant plastic refers to a plastic material with special properties, which can maintain good performance in an environment of long-term wear and friction, such as PE (polyethylene), PAI (polyamide-imide), etc.
[0048] Wear-resistant plastic is used as the material of the limit buckle 121. The wear-resistant plastic meets the functional requirements of the limit buckle 121 and also provides advantages such as lightness, durability and cost-effectiveness. The wear resistance and durability of the wear-resistant plastic ensure that the limit buckle 121 can effectively limit the second scissors body 200 for a long time.
[0049] like Figure 4 As shown, in an optional embodiment of the present invention, the length of the limiting buckle 121 is L, the length of the connecting portion between the first blade 120 and the first handle 110 is M, and L>M.
[0050] Among them, when L>M, when reassembling the detachable scissors, the user can close the first handle 110 and the second handle 210 inward. At this time, under the action of the rotational thrust of the second handle 210, the limit buckle 121 moves the limit buckle body 124 along the limit slot 122 to a position where the second blade 220 can be limited; when the length L of the limit buckle 121 is less than M, if the limit buckle body 124 is to be moved along the limit slot 122 to a position where the second blade 220 can be limited, the user needs to press it manually.
[0051] In an optional embodiment of the present invention, the length of the connecting portion between the first blade 120 and the first handle 110 is M, and L>M improves the convenience of using the detachable scissors.
[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
