Description

Technical Field

[0001] The invention relates to the technical field of nail clippers, in particular to a pair of nail clippers with wide jaw openings. Background Art

[0002] Existing nail clippers are designed with a flat head and straight line, which requires the user to bend the wrist outward when trimming nails, which is a heavy burden and inconvenience for arthritis patients, pregnant women and obese people. In addition, the flat head and crescent-shaped trimming edge are not convenient for users to trim ingrown toenails; for nail clippers composed of a handle, a connecting column and a V-shaped handle, the width between the blades is limited by the design of the V-shaped handle and cannot be made too wide. The connecting column is connected to the handle through a hook structure, which is easy to fall off during use and cannot withstand strong pressure trimming; for double-handled nail clippers (wide-jaw opening nail clippers), the two handles are respectively formed with blades and are rotatably connected, and an external spring is arranged between the two handles. This design can increase the width of the two blades and is more resistant to strong trimming.

[0003] The above two types of nail clippers will cause nail fragments and toenails to fly when in use. To solve this problem, some manufacturers set barrier plate structures on both sides of the two cutting edges. However, due to the width requirements between the two cutting edges and the sharpening process of the two cutting edges, this barrier plate structure cannot achieve a fully enclosed barrier effect, that is, there is still a gap between the upper and lower barrier plates, which results in a small amount of debris still flying out during the nail trimming process.

[0004] Therefore, there is an urgent need for a nail clipper with a wide jaw opening that can solve one or more of the above problems. Summary of the invention

[0029] During assembly, the second handle 2 passes through the through slot 100 and docks with the first handle 1 , wherein the through slot 100 limits the rotation of the first blade head 10 , thereby limiting the opening width between the upper blade 11 and the lower blade 201 .

[0030] like Figure 4 , Figure 5 and Figure 7 As shown, the head end of the second handle 2 is a second blade head 20, and the second blade head 20 is provided with a docking position 21, which is the docking position of the first blade head 10 and the second blade head 20, and the docking position 21 is provided with a mounting groove 210. A lower blade 201 is formed at the front end of the second blade head 20, and the lower blade 201 extends upward and forward. The left and right ends of the lower blade 201 are marked as a lower blade head end 201A and a lower blade tail end 201B. The forward extension of the lower blade head end 201A is greater than that of the lower blade tail end 201B, and the lower blade head end 201A forms a pointed cone shape.
