Description

Technical Field

[0001] The utility model relates to the technical field of nail clippers, in particular to a pair of nail clippers with a limited locking structure. Background Art

[0002] At present, there are many types of nail clippers on the market. Their structures include a pliers head, two handles, a reset member between the handles, or a spring sheet is provided on the inner side of the two handles for resetting the handles after clamping. However, using the spring sheet to reset the two handles will result in insufficient resetting elasticity of the handles, and even cause the two handles to open excessively, which is easy to pinch the user's fingers. Moreover, when the nail clippers are not in use, the pliers heads are opened, and the sharp pliers mouths are easy to scratch when not paying attention, which poses a safety hazard.

[0003] In 2020, the inventor proposed a pair of nail groove pliers with a closed rotary locking function, Chinese patent publication number CN213758496U. The above patent solves the problem of excessive opening and closing of the pliers head through a closed rotary locking structure. However, during use, the rotary locking part easily rotates synchronously with the up and down opening and closing of the pliers body, causing the locking protrusion to accidentally enter the special-shaped locking groove, thereby increasing the difficulty of operation.

[0004] Therefore, the present invention proposes a nail clipper with a limited locking structure to solve the problem of the locking protrusion accidentally entering the special-shaped locking groove. Utility Model Content

[0051] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0052] Example 1

[0053] refer to Figure 1-3 As shown, a nail clipper with a limited locking structure includes: a first jaw part 100, a second jaw part 200, and a locking mechanism 400, wherein the front ends of the first jaw part 100 and the second jaw part 200 are rotatably connected to each other through a connecting assembly 300, a travel channel 110 is provided on the first jaw part 100, and a limit column 210 is provided on the second jaw part 200, and the limit column 210 moves in the travel channel 110. Since the two ends of the travel channel 110 are closed, the limit column 210 can only operate in a closed space to prevent the first jaw part 100 and the second jaw part 200 from opening and closing too much.

[0054] The locking mechanism 400 in this embodiment is located on the outside of the second jaw part 200, and includes: a locking member 410, and a locking hole 420 that cooperates with the locking member 410. The locking hole 420 is located on the first jaw part 100 and is in the shape of a hole. Preferably, the locking hole 420 is a threaded hole.

[0055] In this embodiment, the locking member 410 is provided with a locking post 430. The locking post 430 passes through the second jaw portion 200 and extends into the locking hole 420, thereby fixing the first jaw portion 100 and the second jaw portion 200 relative to each other and preventing them from moving. Generally, the locking member 410 and the locking post 430 are an integrated structure. The surface of the locking member 410 is provided with anti-slip grooves 440. The outer wall of the locking post 430 is threaded. The locking post 430 is screwed to the locking hole 420 and the locking post 430 is screwed to the second jaw portion 200.

[0056] Specifically, during use, the locking member 410 is rotated to drive the locking post 430 to rotate until it is completely rotated out of the locking hole 420, thereby releasing the relative fixation between the first jaw portion 100 and the second jaw portion 200, and completing the manicure operation. When not in use, the first jaw portion 100 and the second jaw portion 200 are closed, and the locking member 410 is rotated to drive the locking post 430 to rotate until it is completely inserted into the locking hole 420, thereby resetting the relative fixation between the first jaw portion 100 and the second jaw portion 200 and preventing operation.

[0057] Example 2

[0058] refer to Figure 4-5As shown, different from Example 1, a pressing spring mechanism 450 is provided between the locking member 410 and the locking column 430. When the locking member 410 is pressed once, the locking column 430 extends into the locking hole 420, so that the first jaw part 100 and the second jaw part 200 are relatively fixed and cannot move; when the locking member 410 is pressed again, the locking column 430 moves out of the locking hole 420, so that the first jaw part 100 and the second jaw part 200 can move relative to each other.

[0059] In this embodiment, the locking post 430 does not need to be provided with threads, and the locking hole 420 does not need to be a threaded hole. The above-mentioned pressing spring mechanism 450 is used for simpler and more convenient operation.

[0060] Example 3

[0061] refer to Figure 5-6 As shown, unlike Example 2, the locking hole 420 in this embodiment is located within the travel channel 110, and the limiting post is replaced by a locking mechanism 400. A pressing spring mechanism 450 is provided between the locking member 410 and the locking post 430. When the locking member 410 is pressed once, the locking post 430 extends into the locking hole 420, thereby fixing the first and second jaw parts 100, 200 relative to each other and preventing them from moving. When the locking member 410 is pressed again, the locking post 430 moves out of the locking hole 420, thereby allowing the first and second jaw parts 100, 200 to move relative to each other.

[0062] In this embodiment, the locking column 430 does not need to be provided with threads, and the locking hole 420 does not need to be a threaded hole. The use of the above-mentioned pressing spring mechanism 450 is simpler and more convenient to operate.

[0063] Example 4

[0064] refer to Figure 7-10 As shown, the present invention also proposes another nail clipper with a limited locking structure, including: a first jaw part 100, a second jaw part 200, and a locking mechanism 400, wherein the front ends of the first jaw part 100 and the second jaw part 200 are rotatably connected to each other through a connecting assembly 300.

[0065] The main difference from Example 1 is that the travel channel 110 and the limit column 210 are not shown in this embodiment, but its structure and principle are the same as those in Example 1. At the same time, the locking mechanism 400 in this embodiment is located between the first jaw part 100 and the second jaw part 200, that is, on the side of the entire device, including: a locking member 410, and a locking hole 420 that cooperates with the locking member 410. The locking hole 420 is located on the first jaw part 100 and is in the shape of a hole; preferably, the locking hole 420 is a threaded hole.

[0066] In this embodiment, a locking post 430 is provided on the locking member 410. One end of the locking post 430 is screwed into the second jaw portion 200, while the other end extends into the locking hole 420, thereby securing the first jaw portion 100 and the second jaw portion 200 relative to each other and preventing movement. Generally, the locking member 410 and the locking post 430 are an integrated structure. The surface of the locking member 410 is provided with anti-slip grooves 440, and the outer wall of the locking post 430 is threaded. The locking post 430 is threadedly connected to the second jaw portion 200.

[0067] Specifically, during use, the locking member 410 is rotated to drive the locking post 430 to rotate until it is completely screwed out of the locking hole 420. At this time, one end of the locking post 430 is completely screwed into the second jaw part 200, thereby releasing the relative fixation between the first jaw part 100 and the second jaw part 200, and the manicure operation can be completed. When not in use, the first jaw part 100 and the second jaw part 200 are closed, and the locking member 410 is rotated to drive the locking post 430 to rotate until it is completely inserted into the locking hole 420. At this time, the remaining end of the locking post 430 remains in the second jaw part 200, thereby making the first jaw part 100 and the second jaw part 200 relatively fixed and unable to be operated.

[0068] Example 5

[0069] refer to Figure 11-13 As shown, the utility model also proposes another nail clippers with a limited locking structure, including: a first jaw part 100, a second jaw part 200, and a locking mechanism 400; wherein, the front ends of the first jaw part 100 and the second jaw part 200 are rotatably connected to each other through a connecting assembly 300, a travel channel 110 is provided on the first jaw part 100, and a locking chamber 460 is provided at one end of the travel channel 110; a limit column 210 is provided on the second jaw part 200, and the limit column 210 moves in the travel channel 110 and the locking chamber 460. Since the two ends of the travel channel 110 are closed, the limit column 210 can only operate in a closed space to prevent the first jaw part 100 and the second jaw part 200 from opening and closing too much.

[0070] The locking mechanism 400 in this embodiment includes a push-pull key 470, a push-pull channel 480, and a locking post 430. The push-pull key 470 is fixedly connected to the limiting post 210 via the locking post 430. The push-pull key 470 moves within the push-pull channel 480 and drives the limiting post 210 to move into or out of the locking chamber 460. The surface of the push-pull key 470 is provided with anti-slip grooves 440.

[0071] Specifically, during use, by pushing the push-pull key 470, the limit post 210 is moved out of the locking chamber 460 and into the travel channel 110, thereby releasing the relative fixation between the first jaw portion 100 and the second jaw portion 200, and completing the manicure operation. When not in use, by pushing the push-pull key 470, the limit post 210 is moved into the locking chamber 460 and into the travel channel 110, thereby fixing the first jaw portion 100 and the second jaw portion 200 relative to each other and preventing operation.
