[0034] Combination Figures 1 to 5 As shown, the utility model discloses a nail clipper with a rotating lock 5, comprising:

[0035] An upper clamp piece 11 and a lower clamp piece 12 connected at the tail; the heads of the upper clamp piece 11 and the lower clamp piece 12 have a clamp mouth 13 for biting;

[0036] A hook nail 2, wherein the hook nail 2 is inserted through the upper clamp piece 11 and the lower clamp piece 12;

[0037] A clamp cover 3, the clamp cover 3 is located above the upper clamp piece 11, and the head of the clamp cover 3 is rotatably connected to the hook nail 2 through a pin 4;

[0038] A rotating lock 5, wherein the rotating lock 5 is rotatably connected to the hook nail 2 via the pin 4 and is located above the jaw 13 of the upper jaw 11, and the rotating lock 5 has a pressing portion for applying pressure to the upper jaw 11;

[0039] The rotating lock 5 rotates under the action of external force, and makes the pressing part have a locking position and an unlocking position relative to the pliers body; when the rotating lock 5 is in the locking position, the pressing part keeps pressing the upper pliers piece 11 to shrink the two pliers mouths 13; when the rotating lock 5 is in the unlocking position, the pressing part separates from the upper pliers piece 11 to fully open the two pliers mouths 13.

[0040] Compared with the prior art, the utility model discloses a nail clipper with a rotating lock 5, in which the rotating lock 5 is arranged at the hook nail 2. When the rotating lock 5 is turned over, the rotating lock 5 acts on the position of the jaws 13 of the upper jaw 11, which makes it easy for the upper jaw 11 to move toward the lower jaw 12, thereby reducing the opening range of the two jaws 13, and when the rotating lock 5 is rotated to the locking position, the two jaws 13 can be kept in a retracted state, so that the nail clippers are locked, the operation is simple and convenient, and the occurrence of cutting fingers and cutting fabrics can be reduced.

[0041] Furthermore, if Figure 2 As shown, the head of the pliers cover 3 has a through slot 31; the rotating lock 5 is located in the through slot 31; when the rotating lock 5 is in the locking position, the rotating lock 5 is inclined relative to the surface of the upper pliers piece 11, and the rotating lock 5 is kept against the upper edge of the through slot 31 under the reaction force of the upper pliers piece 11, so that the rotating lock 5 remains stationary when it is rotated to the locking position, thereby locking the nail clippers.

[0042] Furthermore, combined with Figure 3 and Figure 4 As shown, in order to enable the rotation of the pressing portion to switch the nail clippers between the locked state and the unlocked state, the pressing portion has a first action surface 51, a pressing arc surface 52 and a second action surface 53 connected in sequence; the pressing arc surface 52 has a center line 521, and the inclination direction of the first action surface 51 relative to the center line 521 is opposite to the inclination direction of the second action surface 53 relative to the center line 521;

[0043] When the rotating lock 5 is in the locking position, the first action surface 51 close to the pressing arc surface 52 acts on the surface of the upper clamp 11;

[0044] During the process of the rotating lock 5 rotating from the unlocked position to the locked position, the first action surface 51 acts on the upper jaw 11, exerting pressure on the upper jaw 11, causing the upper jaw 11 to move downward until the first action surface 51 transitions to the second action surface 53, and the upper edge of the through groove 31 abuts against the rotating lock 5. At this time, the reaction force of the upper jaw 11 on the rotating lock 5 causes the rotating lock 5 to rotate in the direction of the through groove 31, thereby locking the rotating lock 5.

[0045] Furthermore, the tail end of the first action surface 51 is connected with a transition arc surface 54 and a third action surface 55 in sequence; when the rotating lock 5 is rotated from the locked position to the unlocked position, after the second action surface 53 is separated from the upper pliers 11, the upper pliers 11 acts on the transition arc surface 54 until the third action surface 55 abuts against the upper pliers 11, and the third action surface 55 is connected to the first action surface 51 through the transition arc surface 54. There is a large angle difference between the third action surface 55 and the first action surface 51, so that when the third action surface 55 abuts against the upper pliers 11, the first action surface 51 is separated from the upper pliers 11, so that after the nail clippers are unlocked, the first action surface 51 will not exert pressure on the upper pliers 11, thereby effectively ensuring the normal use of the nail clippers.

[0046] Furthermore, when the rotating lock 5 is in the locked position, there is a gap 14 between the two jaws 13. When the rotating lock 5 is rotated from the locked position to the unlocked position, the pressing arc surface 52 will rotate from the side close to the first action surface 51 to the side close to the second action surface 53, and will pass through the lowest point of the pressing arc surface 52 during the rotation process, that is, during the rotation process, the pressing arc surface 52 will further press the upper jaw 11 downward, so there needs to be a certain gap 14 between the two jaws 13 to allow the upper jaw 11 to move further downward, thereby ensuring the smooth rotation of the rotating lock 5 and protecting the two jaws 13 from damage caused by the above factors.

[0047] Preferably, the first action surface 51, the second action surface 53 and the third action surface 55 can be, but are not limited to, a plane or a combination of a plane and an arc surface. In the present invention, the first action surface 51, the second action surface 53 and the third action surface 55 are all planes.

[0048] Furthermore, in order to enable the user to conveniently rotate the rotating lock 5, the rotating lock 5 has a toggle portion 56; when the rotating lock 5 is in the locked position, the toggle portion 56 is located on the upper side of the pliers cover 3; when the rotating lock 5 is in the unlocked position, the toggle portion 56 is located on the front side of the pliers cover 3, and a space for finger insertion is provided between the toggle portion 56 and the jaw 13 of the upper pliers piece 11. The toggle portion 56 includes the tail end position of the third action surface 55, and when the rotating lock piece is in the unlocked position, a space for finger insertion is provided between the third action surface 55 and the upper pliers piece 11.

[0049] like Figure 5 As shown, when the rotating lock 5 is in the unlocking position, the pliers cover 3 is flipped upward and then rotated 180° laterally. During the process of the pliers cover 3 rotating 180° laterally, since the pliers cover 3 and the rotating lock 5 are connected to the hook nail 2 through the pin 4, the rotating lock 5 will also rotate 180° laterally synchronously.

[0050] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
