Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the orientation words, if there are terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and positional relationship indicated are based on the orientation or positional relationship shown in the drawings, and only for the convenience of describing the present invention and simplifying the description, it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and not be construed as limiting the specific scope of the present invention.

The present invention will be further explained with reference to the accompanying drawings:

as shown in FIGS. 1 to 4, a preferred embodiment of the present invention comprises a pull ring 1, a pull arm 2, first connecting plates 3, second connecting plates 4 and a wire clamp 5, wherein the pull ring 1 is rotatably connected to the rear end of the pull arm 2, one end of each of the first connecting plates 3 is rotatably connected to both sides of the middle portion of the pull arm 2, and the other end thereof is rotatably connected to both sides of the rear portion of the wire clamp 5, one end of each of the second connecting plates 4 is rotatably connected to both sides of the front end of the pull arm 2, and the other end thereof is rotatably connected to both sides of the front portion of the wire clamp 5, the wire clamp 5 comprises an upper clamp arm 51 and a lower clamp arm 52, the middle portion of the upper clamp arm 51 is rotatably connected to the middle portion of the second connecting plate 4, the width of the middle portion of the second connecting plate 4 is greater than the width of both ends of the second connecting plate 4, and since there is only one connecting point between the upper clamp arm 51 and, the upper tong arm 51 and the lower tong arm 52 are combined into a whole as far as possible due to the structural design that the upper tong arm 51 and the lower tong arm 52 are closed, and the design can reduce the left-right sliding of the upper tong arm 51 and increase the protection and fixation of the upper tong arm 51 because the connecting structure of the upper tong arm 51 is relatively fragile.

The shape of going up tong arm 51 cross section is triangle-shaped, and this shape enables to go up tong arm 51 and second connecting plate 4 and is connected more firmly, and the shape of lower tong arm 52 cross section is for falling trapezoidal, and first connecting plate 3 and second connecting plate 4 are connected respectively in lower tong arm 52 bottom both ends, make the atress even, are difficult to let first connecting plate 3 or second connecting plate 4 atress alone, lead to taking place deformation after long-term the use.

The connecting mode between pull ring 1, arm 2, first connecting plate 3, second connecting plate 4 and the last tong arm 51 is for riveting, compares in bolted connection more firmly, is difficult to drop, and first connecting plate 3 and second connecting plate 4 are connected with lower tong arm 52 through

round pin axle

6, and 6 one side of round pin axle carries out the joint through the rivet and fixes, reduces the possibility that drops.

The edges of the two ends of the U-shaped wire clamping groove 521 and the inverted trapezoidal pressing block 511 are arc-shaped edges, so that wires are protected, and abrasion to the wires is reduced.

The pull arm 2 is provided with an empty groove 21, and the bottom of the lower clamp arm 52 is provided with a cavity 523, so that the weight of the wire clamp is reduced, and the possibility of deformation is reduced.

When the wire clamping device is used, only a wire rod needs to penetrate through the wire clamping pliers 5, the pull ring 1 is pulled backwards, the pull ring 1 drives the pull arm 2, the pull arm 2 controls the first connecting plate 3 and the second connecting plate 4 to rotate, the upper pliers arm 51 is pressed down, the wire rod is clamped, and wire clamping operation is achieved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
