s2: after the first group of electric wires and cables and the second group of electric wires and cables are connected, a first wire guide (201) is butted with a second wire guide (205), a rotating sleeve (2) is rotated, the rotating sleeve (2) can drive a cam ring (209) to rotate, when the protruding end of the cam ring (209) rotates to the bottom of a fastening bolt (204), a clamping hook (203) can be jacked up through the fastening bolt (204), the end part of the clamping hook (203) is clamped into a clamping groove (207), a fixing ring (208) is rotated to clamp the clamping hook (203), and if the clamping depth of the clamping hook (203) is not enough, the fastening bolt (204) can be adjusted;
s3: after the clamping assembly is clamped, the electric wires and the cables are kept under proper tension, the sliding rod (104) is pulled out, and the two groups of electric wires and the cables are respectively fixed through the two groups of cable clamping devices (105);
s4: if meeting unexpected pulling, firstly, the wire and cable can be pulled out of the sliding rod (104) through the cable clamping device (105), the sliding rod (104) can drive the triangular rotating plate (103) to rotate by pulling, the triangular rotating plate (103) can jack up the sliding clamping plate (102) by rotating, so that the sliding clamping plate (102) slides and rises along the inner walls of the first shell (1) and the second shell (107), the wire and cable between the sliding clamping plate (102) and the fixed clamping plate (101) can be clamped, the pulling force generated by pulling is converted into the friction force of the surface of the wire and cable, the wire and cable is not influenced by the pulling force, the phenomenon of disconnection and short circuit can not occur, the normal construction and production can not be influenced, and the occurrence of electric shock accidents can also be avoided;
s5: when two sets of wire and cable tension are great when not being convenient for butt joint, fix two sets of wire and cable respectively in first casing (1) and second casing (107) after, with sliding block (3) push down spout (108), card key (302) at first can retract then block in draw-in groove (301), lock sliding block (3), penetrate tie bolt (304) at two sets of sliding block (3) inner walls, thereby it can make first casing (1) and second casing (107) be close to each other and be convenient for the butt joint to move tie bolt (304) through twisting, also can cooperate taut subassembly to use, when not needing supplementary butt joint, loosen tie bolt (304), it takes out (3) to move tie plate (109), the equipment is convenient, and is convenient to carry.
