The weight of the years
Lao Zhang is an old maintenance worker in the factory with superb skills. But he is old, especially when the production task is tight, he always has back pain, which affects the production progress.
A ray of hope
Until one day, the factory bought a new batch of equipment, and Lao Zhang debugged it as usual. Just then, the new technician Xiao Li came over with a copper joint in his hand."Master Zhang, try this copper quick-twist joint, just plug it in and twist it, and it's easy to get it done!" Xiao Li introduced enthusiastically.
Lao Zhang inserted the air duct into the joint, and with a "click", the air duct was firmly fixed. Then, Lao Zhang tested the sealing with soapy water, and there were no bubbles at all."Oh, this thing is easy to use!" Lao Zhang quickly connected the equipment with the new joint. As a result, the work that originally took half a day to complete can now be completed in two hours! And the joint is tightly connected, there is no need to worry about leakage.
The return of smiles
From then on, Lao Zhang's maintenance toolbox has added this "artifact". It not only improves work efficiency and relieves back pain, but also makes people smile more. Moreover, he often tells everyone he meets: "Copper quick-tightening fittings are really good news for us!"
