Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1 to 3, the frog-heart clip provided in this embodiment includes: the clamping device comprises a clamp body, a first clamping piece 31 and a second clamping piece 32, wherein an opening is formed in the upper end of the clamp body, and the part of the clamp body, which is close to the opening, is a clamping part and is usually in a clamping state; the part of the clamp body far away from the opening is a pressing part 4, and the opening of the clamping part can be opened by inwardly pinching the pressing part 4.
The clamping part comprises a first clamping part 11 and a second clamping part 12, and an opening is formed between the first clamping part 11 and the second clamping part 12; a first rotating shaft 21 is arranged at one end of the first clamping part 11 close to the opening, a second rotating shaft 22 is arranged at one end of the second clamping part 12 close to the opening, and the first rotating shaft 21 and the second rotating shaft 22 are collinear.
The first clamping piece 31 is rotatably arranged on the first clamping portion 11 through the first rotating shaft 21, the second clamping piece 32 is rotatably arranged on the second clamping portion 12 through the second rotating shaft 22, and when the clamp body is in a clamping state, the first clamping piece 31 and the second clamping piece 32 are abutted against each other.
The frog heart clip provided by the embodiment is always in a clamping state, when the frog heart clip is used, the clamping part is pinched inwards by double fingers, so that the opening is opened, and the first clamping piece 31 and the second clamping piece 32 are separated along with the clamping part; when clamping, the first clamping piece 31 and the second clamping piece 32 are abutted against each other and clamped on the frog heart. The frog heart clip has the following beneficial effects: on one hand, the first clamping piece 31 and the second clamping piece 32 improve the clamping stress area, so that the frog heart damage caused by too thin clamping ends can be prevented; on the other hand, the first clamping piece 31 and the second clamping piece 32 are respectively connected with the clamping part in a rotating mode through the rotating shaft, when the clamp body rotates downwards, the first clamping piece 31 and the second clamping piece 32 are not moved, and the clamp body can be prevented from driving the frog heart to twist, so that the frog heart is prevented from being damaged.
Specifically, the first jaw 31 and the second jaw 32 are silicone pieces. Because the silica gel sheet material is soft and elastic, can prevent to destroy frog heart.
