Installation guide：
1. On two steel bars, threads in two different directions, clockwise and counterclockwise, are processed respectively;
2. JBCZ customizes positive and negative thread sleeves, 50% of the sleeves are clockwise threads and 50% are counterclockwise threads to match the steel bar threads in the first step
3. Rotate the sleeve to tighten the two steel bars at the same time, and easily complete the connection without rotating the steel bars and only rotating the sleeve
