As a preferred embodiment, the first connecting mechanism 100 includes a first link 120 and a first spring member 110, the second clamp head 3, the first spring member 110, the first link 120 and the second handle 5 are sequentially connected, the second connecting mechanism 200 is a second link, one end of the second link is connected with the second scissor head 7, the other end is movably connected with the first link 120, and when the second handle 5 moves (can slide or rotate in combination with the previous embodiment) to the first closed position during the scissor action, the second handle 5 drives the second clamp head 3 to rotate to close with the first clamp head 2 through the first link 120 and the first spring member 110, so as to complete the clamping action; when the second handle 5 continues to move from the first closing position to the second closing position, the first spring member 110 deforms elastically, the biting force between the second clamp head 3 and the first clamp head 2 increases, and the first connecting rod 120 drives the second connecting rod to pull the second scissor head 7 to rotate to close with the first scissor head 6, so that the shearing action is completed. The present embodiment employs a linkage transmission and implements a differential transmission by providing a first spring member 110, thereby implementing a clamping-then-shearing action. The first connection mechanism 100 reaches a specific position and then drives the second connection mechanism 200 can be implemented in various manners. A preferred embodiment is given below for reference.
As a preferable mode of the above embodiment, the first link 120 and the second link are movably connected through the second pin shaft 10 and the bar-shaped hole 9, the bar-shaped hole 9 is disposed on the first link 120 or on the second link, and when the second handle 5 moves to the first closed position during the cutting nipper action, the second pin shaft 10 relatively slides to one end of the bar-shaped hole 9, so as to realize the traction of the first link 120 on the second link. The bar-shaped hole 9 is shown to be arranged on the first connecting rod 120, and the bar-shaped hole 9 is arranged on the second connecting rod to realize differential transmission based on the same principle. Of course, any other structure capable of achieving differential transmission can be adopted.
As a preferable mode of the above embodiment, when the cutting pliers complete the opening motion, the second handle 5 moves from the second closed position to the first closed position, the first spring member 110 elastically contracts, the second pin 10 relatively slides to the other end of the bar-shaped hole 9, and when the second handle 5 continues to move from the first closed position to perform the opening motion, the first connecting rod 120 drives the second connecting rod, and the second connecting rod drives the second cutting pliers to rotate to realize opening. The present embodiment achieves the opening of the shear portion by mechanical transmission, although other means may be employed. If an elastic member (such as a torsion spring) for keeping the first shear head 6 and the second shear head 7 in an open state is arranged between the first shear head 6 and the second shear head 7, when the traction force for shearing action is eliminated, the first shear head 6 and the second shear head 7 are in an open state under the action of elastic force.
The first spring member in embodiments of the present invention may be a telescoping spring or any other resilient member that is telescoping.

Under the principle of the invention, the shapes, the connection modes, the relative positions and the like of all the parts can be properly adjusted for better realizing the actions of transmission, clamping, shearing and the like. If the body 1 can be a strip-shaped plate body or a tube body, when the body 1 is a plate body, the first connecting mechanism 100 and the second connecting mechanism 200 can be located on the same side of the body 1 or on two sides of the body 1 respectively, and when the first connecting mechanism 100 and the second connecting mechanism 200 are located on two sides of the body 1 respectively, a strip-shaped hole can be formed in the body, so that the first connecting mechanism 100 and the second connecting mechanism 200 can be connected through the strip-shaped hole in a transmission manner, or the first connecting mechanism 100 and the second connecting mechanism 200 can be connected across the body 1 to clamp the body. When the forceps body is a tube body, the first and second connection mechanisms 100 and 200 may be provided inside the forceps body. In addition, for reasonable layout of the shearing part and the clamping part, the end part of the clamp body 1 can be shaped like bending, bifurcation, perforating and the like. In the embodiment of the invention, the shearing part and the clamping part are arranged side by side, namely, when the shearing part and the clamping part are opened and closed in the vertical direction, the shearing part and the clamping part are arranged side by side left and right, and one of the shearing part and the clamping part is arranged on the left side and the other is arranged on the right side according to the requirement. Likewise, the directions in which the shearing portion and the clamping portion are opened may be the same or different, for example, the rotatable second binding clip 3 and the second binding clip 7 may both be opened upward, or one (second binding clip 7) may be opened upward and the other (second binding clip 3) may be opened downward as shown in fig. 1. In addition, in order to further reduce the overall width of the shearing portion and the clamping portion, the first scissor head 6 is fixed to the side face of the first scissor head 2, or further, a blade portion is formed on the side face of the first scissor head 2 as the first scissor head, and the blade portion formed on the side face of the first scissor head 2 cooperates with the second scissor head 7 to achieve shearing. One of the points of the above embodiment is that the second binding clip 3 and the second scissor head 7 need to be opened to the same side, which is different from fig. 1.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
