The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as the case may be.

The blade of current tailor scissors is the straight form usually with the junction of handle, and this also makes on the one hand, and the handle can bulge the volume after being connected with the blade, influences the holistic pleasing to the eye degree of scissors, and on the other hand, the handle of current structure is less with the area of contact of being connected of blade, and the joint strength of handle and blade is lower, can't guarantee the quality of tailor scissors.

Based on the problems, a bending structure at the handle of the tailor scissors is urgently needed, the connection strength of the handle and the blade is improved, and the product quality of the scissors is guaranteed.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only some embodiments of the present application, and not all embodiments of the present application. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

In an implementable embodiment, as shown in fig. 1 to 5, a bending structure at a handle of a tailor's scissors can at least comprise two blades 1 hinged with each other, each blade 1 has a body 11 and a bending part 12, and each blade 1 is connected with a handle 2 at the bending part 12. Concave height difference 13 is formed between the side surface of at least one bending part 12 and the corresponding side surface of the blade 1, so that the connecting contact surface 14 between the handle 2 and the corresponding body 11 is increased, namely, when the handle is connected to the blade in a casting mode, the contact area between the handle and the blade can be increased, and the connecting strength between the handle and the blade is improved. Meanwhile, the concave height difference can accommodate the thickness of part of the handle, the protruding part of the handle relative to the blade is reduced, and the overall attractiveness of the scissors is improved.

It should be noted that the concave height difference 13 means that the side of the bending part 12 is lower than the side of the blade 1. Wherein the height of the concave height difference 13 may be between 0.5mm and 4.5 mm.

The two blades 1 may be a first blade 3 and a second blade 4, respectively.

In an embodiment, as shown in fig. 2 and 3, the bent portion 12 of the first blade 3 or the second blade 4 may have a concave height difference 13 between three sides and the corresponding side of the blade 1, so that the connection surface of the handle 2 and the blade 1 may be increased by three connection contact surfaces 14 compared to the existing straight blade structure.

In another embodiment, as shown in fig. 4 and 5, the bent portion 12 of the second blade 4 or the first blade 3 has a concave height difference 13 between two side surfaces and the corresponding side surface of the blade 1, so that two connecting contact surfaces 14 can be added to the connecting surface of the holder 2 and the blade 1 compared with the existing straight blade structure.

In practical use, the concave height difference 13 between the body 11 and the bending part 12 can be formed by placing the blade 1 in a die after high-frequency heating and pressurizing by a hydraulic press.

Of course, the concave height difference 13 can also be formed by grinding with a water mill and milling with a milling machine.

In an implementation, the handle 2 may be made of aluminum alloy and is connected to the blade 1 by aluminum alloy gravity casting.

In practical application, the bent part 12 can be heated to 800 ℃ by a high-frequency machine, and then the bent part 12 of the blade 1 is placed into a mold for aluminum alloy casting, so that aluminum alloy liquid can be fully fused with the blade 1 in the casting process, and the connection strength is improved.

In an implementable embodiment, the handle 2 comprises correspondingly a first handle 21 and a second handle 22. The first handle 21 is provided with an abutting block 211 on a side thereof adjacent to the second handle 22. The second handle 22 is provided with the anti-pinch plate 221 on the side close to the first handle 21, and when the abutting block 211 and the second handle 22 abut against each other on the side close to the first handle 21, the anti-pinch plate 221 is located on the side of the abutting block 211. In this way, when the user opens and closes the first handle 21 and the second handle 22 by holding the hands, the pinching prevention plate 221 prevents the user's hands from being pinched by separating the hands to the outside, and the contact area when the first handle 21 and the second handle 22 are closed is reduced by providing the abutting block 211, thereby similarly preventing the user's hands from being pinched when operating the scissors.

Furthermore, for the connection mode of the handle and the blade, the bent part can be firstly heated to 800 degrees by a high-frequency machine, and then the bent part of the blade is placed into a mold for aluminum alloy casting, so that aluminum alloy liquid can be fully fused with the blade in the casting process, and the connection strength is improved.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
