Description

Technical Field

[0001] The present invention relates to a pet nail trimmer, and the present invention relates to the following tool for cutting pet nails, that is, as a tool for cutting pet nails, since a circular blade is formed in a basic setting state, a user can choose a method of directly placing the nail on the circular blade for cutting and a method of opening the blade of the tool to insert the nail from the front and cut, so that the degree of opening can be adjusted according to the classification of two objects, cats and dogs, to maximize the convenience of use. Background Art

[0002] This section merely provides background information related to the contents of the present application and does not necessarily constitute prior art.

[0003] In the existing pet nail trimmer, two parts are combined in the shape of scissors, and the semicircular blades at one end are made to face each other and overlap in a manner without distinguishing between dogs and cats, and are used after being opened like scissors.

[0004] Especially when cutting long and thin nails like cats, this kind of pet nail trimmer is easy to cut wrong. If it cuts too deep, it will hit the nerve, which may cause bleeding. In order to prevent this, in the existing technology, the circular blades (cutting blades) of each component are aligned with each other, and the nail is placed on this blade and cut. However, this is because the blade is perforated into a circle and cannot be opened in a semicircular shape. Therefore, it is impossible to approach from the front of the blade, so there is a problem that it can only be used when the diameter of the animal's nail is smaller than the diameter of the hole. In addition, some users don't like to aim the nail and put it in to cut.

[0005] Furthermore, since the nails of dogs and cats are of different sizes, a single type of blade cannot be used for the different sizes. Therefore, when raising a dog and a cat at the same time, there is the inconvenience of needing to purchase two types of trimmers for use.

[0006] In the present invention, the cutting method using two semicircular blades opened like scissors is called open cutting, and the cutting method using a blade perforated into a circular shape is called hole cutting.

[0013] Patent Document 0004: Korean Design License No. 30-1210834 Summary of the invention

[0014] The present invention is used to solve the above-mentioned problems, overcome the shortcomings of the existing tools for cutting two types of pet nails, and use only the advantages according to the orientation of the object or user of the nail trimming. In this way, the nail can be directly placed into the circular blade shape in one tool and cut (hole-type cutting method), or the blade can be opened to approach and cut from the front (open cutting method).

[0015] The pet nail trimmer of the present invention is characterized in that the cutting blades on the front sides of the first body and the second body connected by a rotating shaft include large cutting blades and small cutting blades of different sizes, and one or more of the large cutting blades and the small cutting blades are formed into a semicircle to form a circular hole or an open structure with the front side opened. The user selects a position adjustment unit to adjust the cutting blade to a position where a circular hole is formed or a position where the front side is open, and then the nail is inserted from the side or from the front to the back for use. When cutting with the small cutting blade, the first body and the second body are only rotated until the small cutting blade cuts the nail.

[0016] The present invention is characterized in that a cutting blade of a single size is used by forming a circular hole through a position adjustment unit or by being arranged in an open structure with a front side opened.

[0017] The present invention is characterized in that the large cutting blade and the small cutting blade are arranged in a row or circumferential direction, and the position adjustment unit can be used to select the first body and the second body to rotate until the small cutting blade cuts the nail or the first body and the second body to rotate until the large cutting blade cuts the nail.

[0018] The present invention is characterized in that the position adjustment unit is a combination of a position adjustment knob rotatably connected to the first body and a circular blade bracket formed on the second body, or a combination of a circular blade bracket formed on the second body and a rotation blocking wall formed on the first body.

[0019] According to the pet nail trimmer of the present invention, if it is placed in the first level according to the position of the position control knob, all the cutting blades form circular holes, and the blades with small circular holes can be cut by inserting a slender cat's nail into the blades and slightly tightening the handle. If it is placed in the second level, the slightly thick nail of a pet dog is inserted into the large circular hole and the handle is tightened more than the first level to cut. In this case, it is also possible to always place the second level to cut the nails of a cat or dog without ignoring the first level. If the position adjustment knob is placed in the third level, the blades of the first body and the second body can be opened into scissors, and the nails of a cat or dog can be placed on the blades through the front opening and cut. Cutting through the hole has the effect of preventing the nail from being inserted too deep and touching the nerve or bleeding. Cutting after opening like scissors has the effect of cutting quickly and conveniently regardless of the thickness of the nail, and also has the effect that the user can choose these two methods of use.

[0020] Since the present invention has the effect of being able to choose between the two methods of hole cutting and open cutting, it has the unique effect of being used in accordance with the orientation habits of the user. Since it has both a small cutting blade that is suitable for cat's nails and a large cutting blade that is suitable for dog's nails, only a single tool is needed to trim the nails of cats and dogs, thereby having the unique effect of reducing costs and facilitating management compared with the previous situation of purchasing and using two tools.

[0032] The present invention is described below. If it is judged that the specific description of the relevant known functions or structures may unnecessarily obscure the main purpose of the present invention, its detailed description will be omitted. In addition, the following multiple terms are defined after considering the functions in the present invention, which may be different according to the intention or convention of the user or application personnel. Therefore, the definitions should be based on the full text of this specification.

[0033] In both Example 1 and Example 2, the blade is configured in a hole-cutting manner and can be used selectively in the hole-cutting manner and the open-cutting manner. In Example 1, the small cutting blade and the large cutting blade are arranged in a row, and in Example 2, the large cutting blade and the small cutting blade are arranged along the circumferential direction with the axis as the center. In Example 3, the position adjustment knob in Example 1 and Example 2 is replaced by a rotation barrier wall.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, in the pet nail trimmer of the present invention, the first body 10 and the second body 20 are connected by a rotating shaft 30. With the rotating shaft 30 as a reference, two cutting blades (large cutting blades 11, 21 and small cutting blades 12, 22) are formed at the front ends of the first body 10 and the second body 20 respectively. The above-mentioned cutting blades are adjusted to the positions for realizing hole cutting and open cutting through the position adjustment unit (position adjustment knob 40, circular blade bracket 27, first tightening stop block 28).

[0036] The first body 10 and the second body 20 use the rotating shaft 30 as a reference to form the above-mentioned cutting blade on the front side and form handles 13 and 23 on the rear side. The above-mentioned cutting blade makes the roughly semicircular small cutting blades 12 and 22 arranged in a row at the front end, and the large cutting blades 11 and 21 are arranged in a row on the rear side.

[0037] This arrangement can be interchanged. Also the arrangement can be interchanged and the first tightening stopper 28 can be removed to be singularized into a trimmer for cats and dogs. In this case, there is a shortcoming that the nail of a thicker dog is far from the axis and needs a larger force to cut the nail.

[0038] The size of the small cutting edges 12 and 22 is enough to cut a cat's nail (diameter 1.8 mm to 2.0 mm), and the size of the large cutting edges 11 and 21 is enough to cut a dog's nail (diameter 3.5 mm to 4.5 mm).

[0039] The large cutting blades 11 , 21 and the small cutting blades 12 , 22 are maintained in a state that looks like a circle by the position adjustment knob 40 supported by the circular blade support 27 .

[0040] The stopper groove 14 and the inner stopper 24 are formed so that the first body 10 and the second body 20 can rotate only within a predetermined angle when the handles 13 and 23 of the first body 10 and the second body 20 are grasped and tightened for trimming nails.

[0041] The stopper groove 14 is formed open toward the second body 20 around the rotating shaft hole 15 of the first body 10 to form a concentric circle corresponding to the rotation of the internal stopper 24, and the internal stopper 24 stops rotating by the closed structure of the two side walls.

[0042] The inner stopper 24 is formed on the bottom surface around the rotating shaft hole 25 of the second body 20 and protrudes toward the bottom. After being inserted into the stopper groove 14 and moving along the stopper groove 14 , the movement is stopped by the two side walls of the stopper groove 14 .

[0043] The first body 10 and the second body 20 are connected by a spring to facilitate operation. To this end, spring grooves 16 and 26 facing each other are formed inside the first body 10 and the second body 20, and springs (not shown) are installed in the spring grooves 16 and 26. The springs are inserted into the spring grooves 16 and 26, and the two sides are respectively fixed to the first body 10 and the second body 20 to elastically support the first body 10 and the second body 20 (the elasticity at this time is the elasticity that allows the first body 10 and the second body 20 to be maximally opened to a direction above the open cutting).

[0044] The structure of fixation by the position adjustment knob 40 and position adjustment for performing hole cutting and open cutting is as follows.

[0045] The upper surface of the circumference of the rotating shaft hole 15 of the first body 10 is formed with three levels of fixing grooves 17 - 1 , 17 - 2 , and 17 - 3 to fix the position adjustment knob 40 at each level.

[0046] Figure 3The first-level position adjustment state formed by the first-level fixing groove 17 - 1 is shown, and only the cat's nails can be trimmed using the small cutting edges 12 , 22 , and the nails cannot be trimmed using the large cutting edges 11 , 21 .

[0047] Figure 4 The second-level position adjustment state formed by the second-level fixing groove 17 - 2 is shown, and both the large cutting edges 11 , 21 and the small cutting edges 12 , 22 can be used.

[0048] Figure 5 The third-level position adjustment state formed by the third-level fixing groove 17 - 3 is shown, which belongs to the maximum opening state and is the position adjustment state for performing an open cutting method.

[0049] A circular blade support 27 and a first tightening stopper 28 are formed on the periphery of the rotating shaft hole 25 of the second body 20 .

[0050] When the circular blade holder 27 is at the bottom supporting the position adjustment knob 40, the cutting blades 11, 21, 12, 22 maintain a circular shape. When the circular blade holder 27 is located above the position adjustment knob 40, the cutting blades 11, 21, 12, 22 are adjusted to the open cutting position.

[0051] The first tightening stop block 28 is used to prevent the large cutting blades 11 and 21 from overlapping each other by being locked on the position adjustment knob 40. That is, when the small cutting blades 12 and 22 are used to trim the cat's nails, although the small cutting blades 12 and 22 are overlapped with each other, the large cutting blades 11 and 21 are prevented from overlapping each other.

[0052] The position adjustment knob 40 is rotatably mounted on the first body 10 via a knob shaft 50 , and includes: a head 41 and a first locking shoulder 42 , which are in direct contact with the circular blade support 27 ; and a knob shaft hole 43 , which is coupled to the first body 10 shaft.

[0053] In addition, the position adjustment knob 40 includes a lock, which maintains the adjustment state of each level by being buckled into one of the three-level fixing grooves 17-1, 17-2, and 17-3. For example, the above-mentioned lock is formed into a structure including a ball that is elastically supported along the direction of being buckled into the fixing grooves 17-1, 17-2, and 17-3 by the elastic force of an elastic component.

[0054] The head 41 is supported by the circular blade support 27 so that the cutting blades 11, 21, 12, 22 are located in a circular hole cutting position or are moved away from the circular blade support 27 to an open cutting position so that the first tightening stop block 28 can pass naturally and form a curve (circle) in the shape.

[0055] The first locking shoulder 42 is used to stop the first tightening stop block 28 from rotating.

[0056] The method of using this embodiment is as follows.

[0057] 1. Hole cutting

[0058] 1) Use a small cutting edge

[0059] When the small cutting blades 12, 22 are used to trim the cat's nails in a hole-cutting manner, a Figure 2 The initial state shown is that the lock of the position adjustment knob 40 is fixed in the first level fixing groove 17-1. In this case, in order to perform hole cutting, the circular blade support 27 supports the head 41 of the knob 40 at the bottom position to make the small cutting blades 12, 22 form a circular hole.

[0060] If the cat's nail is inserted into the hole in a manner almost perpendicular to the circular hole formed by the small cutting blades 12, 22 according to the length to be trimmed and the handles 13, 23 are tightened, the nail will be cut. Figure 3 As shown, the first body 10 and the second body 20 rotate via the rotation axis 30 and make the small cutting edges 12 and 22 cross and trim the nails.

[0061] During this process, the first tightening stop block 28 is locked on the first locking shoulder 42 to prevent the second body 20 from rotating, that is, the cat's nails can be trimmed by lightly tightening.

[0062] If the handles 13 and 23 are loosened, the first body 10 and the second body 20 will rotate to the initial positions due to elasticity, so that the cutting blades 11, 21, 12, and 22 will open and return to a circular shape.

[0063] 2) Use a large cutting edge

[0064] When using the large cutting blades 11, 21 to trim the nails of a dog in a hole-cutting manner, the position adjustment knob 40 is fixed to the second level fixing groove 17-2. In this case, the circular blade bracket 27 is fixed to the bottom of the head 41 of the position adjustment knob 40 so that the large cutting blades 11, 21 form a circular hole.

[0065] If the dog's nail is inserted into the hole in a manner almost perpendicular to the circular hole formed by the large cutting blades 11, 21 according to the length to be trimmed and the handles 13, 23 are tightened, the nail will be cut. Figure 4 As shown, the first body 10 and the second body 20 rotate through the rotating shaft 30 and make the large cutting edges 11 and 21 cross and trim the nails. In this case, when the second body 20 rotates due to the fixed position of the position adjustment knob 40, the first tightening stop block 28 passes through the first locking shoulder 42 of the position adjustment knob 40 to make the large cutting edges 11 and 21 completely cross, and then stops through the stop block hole 14 and the internal stop block 24.

[0066] If the handles 13 and 23 are loosened, the first body 10 and the second body 20 will rotate to the initial positions due to elasticity, so that the cutting blades 11, 21, 12, and 22 will open and return to a circular shape.

[0067] 2. Open cutting

[0068] like Figure 5 As shown, the position adjustment knob 40 is fixed in the third-level fixing groove 17 - 3 . The third level is a position where the head 41 of the position adjustment knob 40 does not interfere with the rotation of the circular blade support 27 .

[0069] Along the diameter of the nail, the handles 13, 23 will be properly spread apart. Figure 5 The inner stopper 24 is shown in a state of being in contact with one side wall surface of the stopper groove 14 and being opened to the maximum extent.

[0070] In this way, the first body 10 and the second body 20 will rotate to open like scissors, so that the small cutting edges 12 and 22 and the large cutting edges 11 and 21 will respectively form a state in which the front side is opened. In this case, the first body 10 and the second body 20 are only opened at an angle where the inner stopper 24 is constrained by the wall surface of the stopper groove 14, and will not be opened further.

[0071] After inserting the nail between the large cutting edges 11, 21 or the small cutting edges 12, 22 from the open front side, the nail is trimmed by tightening the handles 13, 23 to cross the large cutting edges 11, 21 and the small cutting edges 12, 22.

[0072] Example 2

[0073] like Figure 6 As shown, in this embodiment, the large cutting edges 11, 21 and the small cutting edges 12, 22 are arranged along the circumferential direction with the rotation axis 30 as a reference. Compared with the first embodiment, there is no difference between the inner side and the outer side.

[0074] The structures of the large cutting edges 11, 21 and the small cutting edges 12, 22 are the same as those of the cutting edges of Example 1 (a structure in which cutting is performed by crossing two cutting edges), and both the open cutting and hole cutting described in Example 1 can be achieved.

[0075] 1. Hole cutting

[0076] 1) Use a small cutting edge

[0077] Figure 7The figure shows the situation of using the small cutting blades 12 and 22 to trim the cat's nails. The position adjustment knob 40 is fixed to the first-level fixing groove 17-1. After the cat's nail is inserted into the hole of the small cutting blades 12 and 22 that maintain the circular shape, the cutting is performed. The specific cutting operation is the same as that of the above-mentioned embodiment 1. The first body 10 and the second body 20 will rotate with a width that is cut only by the small cutting blades 12 and 22.

[0078] 2) Use a large cutting edge

[0079] like Figure 8 As shown, the position adjustment knob 40 is fixed in the second-level fixing groove 17-2, and the dog's nail is inserted into the hole of the large cutting blades 11, 21 that maintain the circular shape and then cut. The specific cutting operation is the same as that in Example 1.

[0080] 2. Open cutting

[0081] like Fig. 9 As shown, the position adjustment knob 40 is fixed in the third-level fixing groove 17-3. If the handles 13 and 23 are opened, the large cutting blades 11 and 21 and the small cutting blades 12 and 22 are opened and the front sides are opened. The dog's nail or the cat's nail is inserted from the open front sides of the large cutting blades 11 and 21 and the small cutting blades 12 and 22 to the rear sides for cutting.

[0082] Compared with the first embodiment, when the large cutting blades 11 and 21 are used, there is no structure to block the insertion of the nail to the front side of the large cutting blades 11 and 21, so the use during open cutting becomes more convenient.

[0083] On the other hand, although not shown in the drawings, the present invention can be formed in a manner in which the small blade and the large blade are arranged along the circumferential direction and the small blade is formed in a special manner for hole cutting, and the large blade can be formed in a manner in which hole cutting and open cutting can be selected.

[0084] The difference is that the large cutting blade can utilize a structure that can achieve hole-type cutting and open cutting like in Example 1 and Example 2, while the small cutting blade uses a circular cutting blade to cut the cat's nails only in a hole-type cutting manner.

[0085] Example 3

[0086] like Fig.10 and Fig.11 As shown, in the present embodiment, the position adjustment knob 40 described in the above embodiment is removed, and a rotation blocking wall 18 for preventing the cutting blades 11, 21, 12, 22 respectively formed in a semicircular shape from opening is formed above the handle 13 adjacent to the periphery of the rotating shaft hole of the first body 10.

[0087] The rotating barrier wall 18 is a structure for restraining (stopping) the rotation of the circular blade bracket 27 formed on the second body 20. If the circular blade bracket 27 contacts the rotating barrier wall 18, the cutting blades 11, 21, 12, and 22 respectively formed on the first body 10 and the second body 20 are aligned to form a pair of circles, into which a cat or dog's nail is placed for hole cutting.

[0088] like Fig.12 As shown, the circular blade support 27 and the rotation barrier wall 18 are also applicable to the configuration in which the cutting blades 11, 21, 12, 22 are arranged along the circumferential direction.

[0089] And, if Fig.13 In the example shown, the small cutting edges 11 and 21 are formed in a circular shape, whereas the large cutting edges 12 and 22 are formed in a semicircular shape, respectively.
