[0020] The wedge-shaped wire clamp 20 includes a wire clamp body 201 and two wedge cores 202. The wire clamp body 201 has an inner cavity for accommodating the two wedge cores 202. The opposite surfaces of the wedge cores 202 form a wire clamping groove. A guide block 2021 is formed at the end of the wedge core 202. A guide groove 2011 is correspondingly formed on the wire clamp body 201. When the wedge core 202 moves, the guide block 2021 moves along the guide groove 2011 from the first end A of the wire clamp body 201 to the second end B, and the width from the first end A to the second end B gradually decreases.

Therefore, after plugging them together, the convex block 70 can be well wrapped, and the connection effect between the two is good. Compared with the existing technology, the connection between the three is more convenient and quick, and the structure is simpler.

[0023] 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.

[0024] 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.
