Description

Technical Field

[0001] The utility model relates to a shearing tool, in particular to an olive-pit scissors. Background Art

[0002] There are a variety of scissors on the market, including those for cutting fabrics and branches in gardens, such as the gardening scissors disclosed in Chinese Patent No. 202221887460.7. However, there are no scissors specifically designed for olive pits. Olive pits are relatively hard, so when purchasing olive pits, customers must choose branch shears with relatively strong cutting capabilities to cut olive pits.

[0003] However, the surface hardness and smoothness of the olive pit are higher than those of the tree branches, which makes it easy for the olive pit to slip when using branch shears to cut the olive pit, and the olive pit is easy to fly out when greater force is applied.

[0004] Therefore, in order to better cut the olive pit, the inventor designed a pair of olive pit scissors. Utility Model Content

[0005] The purpose of the utility model is to provide an olive pit scissors which can cut olive pits more smoothly.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A pair of olive-pit scissors, characterized in that it comprises a first handle and a second handle hinged together, the head of the first handle being a shearing portion with a blade, the head of the second handle being an annular limiting portion for being sleeved on the olive pit, the inner ring of the annular limiting portion being provided with sharp teeth, a step being provided between the sharp teeth and the side of the annular limiting portion away from the shearing portion, the step allowing the sharp teeth, which are thinner than the annular limiting portion, to be closer to the shearing portion.

[0008] Furthermore, the inner ring of the annular limiting portion is provided with a plurality of sharp teeth of different heights.

[0009] Furthermore, the annular limiting portion is in a circular ring shape, and the sharp teeth are distributed on both sides of the inner ring of the annular limiting portion.

[0010] Furthermore, the pointed teeth are flush with the side surface of the annular limiting portion close to the shearing portion.

[0011] Furthermore, the blade is an inwardly concave arc blade.

[0012] Furthermore, the olive-core scissors also include a built-in spring, which provides elastic force for opening or closing the olive-core scissors.

[0013] Furthermore, the olive-core scissors are also provided with a locking structure, which can lock the first handle and the second handle in a closed state or an open state.

[0014] Furthermore, the locking structure includes a shift block, a cam piece and a limit pin. A concave cavity is provided on the inner side surface of the second knife handle close to the first knife handle, the cam piece is provided in the concave cavity, the shift block is provided on the outer side surface of the second knife handle, the shift block is connected to the fixed end of the cam piece, and the cam piece is driven to swing by the shift block. The limit pin is provided on the first knife handle, and part of the limit pin protrudes into the concave cavity. During use, the cam piece is swung so that the swinging end of the cam piece blocks the moving path of the limit pin to lock the position of the limit pin, thereby locking the position between the first knife handle and the second knife handle.

[0015] Furthermore, the concave cavity includes a first chamber and a second chamber, the moving path of the limit pin is located in the first chamber, and the fixed end of the cam piece is located in the second chamber; by swinging the cam piece, the cam piece can be accommodated as a whole in the second chamber, and the swinging end of the cam piece can also be swung into the first chamber.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The annular limiting portion of the utility model can be put on the olive pit, and the position of the olive pit can be well limited through the cooperation of the sharp teeth.

[0018] More importantly, the utility model sets a step so that the sharp teeth with a thickness smaller than the annular limit portion can be closer to the shearing portion. When shearing the olive pit, the force point of the sharp teeth on the olive pit will be closer to the shearing portion, making the shearing smoother and the olive pit less likely to pop out during shearing.

[0019] 2. The utility model further arranges the pointed teeth into a structure of varying heights, i.e., an irregular structure, which can better clamp the olive pit during shearing. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Example:

[0033] like Figures 1 to 6The olive-core scissors of this embodiment are shown, which include a first handle 100, a second handle 200, a built-in spring 700, a hinge shaft 300 and a locking structure.

[0034] The first handle 100 and the second handle 200 are each provided with a hinge hole 800 near the head. The hinge shaft 300 passes through the hinge hole 800 to connect the first handle 100 and the second handle 200, thereby hingedly connecting the first handle 100 and the second handle 200 together and enabling relative rotation. The tail of each of the first handle 100 and the second handle 200 is covered with a rubber sleeve 500 for the user to grasp.

[0035] The head of the first handle 100 is a shearing portion 101, and a blade 102 is provided on one side of the shearing portion 101. The blade 102 of this embodiment is an inwardly concave arc blade, which can increase the force-bearing area with the olive pit during shearing.

[0036] The head of the second handle 200 is an annular retaining portion 201. This ring-shaped retaining portion 201 is designed to fit over the olive pit during cutting. The inner ring of retaining portion 201 is equipped with multiple sharp teeth 202 of varying heights. These teeth 202 are located on both sides of the inner ring and are thinner than the retaining portion 201. During cutting, the multiple sharp teeth 202 provide a secure grip on the olive pit, preventing it from popping out and ensuring smoother cutting.

[0037] Most importantly, Figure 2 As shown, a step 203 is provided between the sharp teeth 202 and the side of the annular limiting portion 201 away from the shearing portion 101. The sharp teeth 202 are flush with the side of the annular limiting portion 201 close to the shearing portion 101. The step 203 allows the sharp teeth 202, which are thinner than the annular limiting portion 201, to be closer to the shearing portion 101. When shearing an olive pit, the force point of the sharp teeth 202 on the olive pit will be closer to the shearing portion 101, that is, the plane where the force point of the sharp teeth 202 on the olive pit is located is closer to the plane where the force point of the blade 102 on the olive pit is located, making shearing smoother and preventing the olive pit from popping out during shearing.

[0038] A spring cavity 801 is provided at the inner end of the hinge hole 800 of the first handle 100 and the second handle 200, respectively. A retaining groove 802 is provided on the side of the spring cavity 801. The internal spring 700 is sleeved on the hinge shaft 300, and the two ends of the internal spring 700 are respectively located in the spring cavity 801 of the first handle 100 and the second handle 200. The two ends of the internal spring 700 are provided with a bent retaining portion 701, which is embedded in the retaining groove 802, thereby limiting the position of the internal spring 700. In this embodiment, when the first handle 100 and the second handle 200 are relatively rotated to close, the internal spring 700 is compressed. When released, the internal spring 700 opens under the elastic force of the internal spring 700.

[0039] The locking structure of this embodiment can lock the first handle 100 and the second handle 200 in a closed or open state. The locking structure includes a shift block 600, a cam plate 900, and a limit pin 400. A cavity 204 is provided on the inner side of the second handle 200 proximate to the first handle 100. The cavity 204 includes a first chamber 204a and a second chamber 204b. One end of the second chamber 204b is provided with a connecting hole 205. The cam plate 900 is disposed within the cavity 204, and the fixed end 901 of the cam plate corresponds to the connecting hole 205. The shift block 600 is disposed on the outer side of the second handle 200. A connecting shaft 601 is provided at one end of the shift block 600. The connecting shaft 601 passes through the connecting hole 205 and is fixedly connected to the fixed end 901 of the cam plate, thereby enabling the cam plate 900 to swing by shifting the shift block 600. By swinging the cam piece 900 , the cam piece 900 can be entirely accommodated in the second chamber 204 b , and the swing end 902 of the cam piece can also be swung into the first chamber 204 a .

[0040] The limiting pin 400 is installed on the first handle 100, and part of the limiting pin 400 protrudes into the first cavity 204a. The first cavity 204a is arc-shaped, and the center of the arc is the center of the hinge shaft 300. When the first handle 100 and the second handle 200 rotate relative to each other, part of the limiting pin 400 will move in the first cavity 204a, that is, the movement path of the limiting pin 400 is located in the first cavity 204a. Figure 5 As shown, when the cam piece 900 is swung so that the cam piece 900 is entirely accommodated in the second chamber 204b, the limiting pin 400 can move freely in the first chamber 204a, and the first handle 100 and the second handle 200 can rotate freely. When the olive pit scissors are in a closed state or an open state, the cam piece 900 can be swung so that the swing end 902 of the cam piece swings into the first chamber 204a, as shown in FIG. Figure 4 As shown, the swing end 902 of the cam piece will block the moving path of the limiting pin 400, thereby locking the position of the limiting pin 400 and further locking the position between the first tool handle 100 and the second tool handle 200.

[0041] When using the olive pit scissors of this embodiment, the annular limiting portion 201 is put on the olive pit, and then the tail ends of the first handle 100 and the second handle 200 are held by hand to apply force so that the first handle 100 and the second handle 200 are continuously closed. During this process, the shearing portion will shear the olive pit.

[0042] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
