[0019] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] like Figure 1-5As shown, the utility model is a new type of cluster tension clamp, characterized in that it includes a main body 2 formed by a pressure plate 4 and a cover plate 3, a pull rod 1 and an inclined wedge pull plate 5, wherein the inclined wedge pull plate 5 is connected to the pull rod 1, and a wire groove is formed on the upper side of the pressure plate 4 and the cover plate 3, wherein the wire groove is a circular arc groove structure, wherein friction lines are arranged in the circular arc groove. The friction lines are equal height trapezoidal tooth structures. The number of wire grooves is four, and two wire grooves are formed between a group of pressure plates 4 and the cover plate 3.

[0021] The pressure plate 4 is provided with a first inclined surface on one side facing the inclined wedge pull plate 5, and the pressure plate 4 and the cover plate 3 are both provided with two, the cover plate 3 is provided on the non-inclined surface side of the pressure plate 4, the pressure plate 4 is located on both sides of the inclined wedge pull plate 5, and second inclined surfaces are formed on both sides of the inclined wedge pull plate 5, and the first inclined surface and the second inclined surface cooperate with each other.

[0022] The number of the wire grooves is four, and two wire grooves are formed between a group of the pressing plate 4 and the cover plate 3 .

[0023] The inclined wedge pull plate 5 is formed with a sleeve for cooperating with the pull rod 1 , and a through hole is formed in the sleeve, and the pull rod 1 is arranged through the through hole.

[0024] When tightening the wire, the tooth-shaped design structure of the utility model can well compress the insulation layer of the wire, increase the friction force on the wire, and prevent the wire clamp from sliding. One side of the pressure plate 4 is designed as a slope, and the two sides of the aluminum alloy inclined wedge pull plate 5 are designed as a sloped wedge-shaped structure. The inclined surface of the inclined wedge pull plate 5 cooperates with the inclined surface of the pressure plate 4.

After the pull rod 1 is anchored, it can be tightened and fixed to obtain a greater grip; the shell of the new type of clustered tension clamp is made of galvanized iron plate, which is anti-corrosive and rust-proof.

[0025] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0026] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
