[0002] In the process of power transmission and transformation, due to the need of wire direction, it is often necessary to perform wire connection operation on cables or electric wires. The electric wires or cables are generally composed of core wires and protective layers (outer skins). For power transmission and transformation, the diameters of the electric wires or cables used are different. In the wire connection operation, the outer skins of the wire connection ends of the electric wires or cables need to be peeled off to expose part of the core wires, and then the core wires of the two electric wires are wrapped with insulating tapes or insulating sleeves. In the prior art, no other treatment is performed on the two core wires, and only the insulating tapes are used to wrap the core wires, which is prone to cause poor contact between the two core wires, thereby affecting the use. Meanwhile, during butt joint, the two electric wires or cables are not easy to be fixed and detached, and are prone to be separated, thereby affecting the butt joint efficiency and being not conducive to operation. Therefore, there is an urgent need for a self-adaptive quick butt joint device for power transmission and transformation electric wires to solve the above technical problems. SUMMARY
