Laid-off workers invented the vehicle shock absorber repair and sealing machine patented

Liu Dongshan, a laid-off worker in Jingmen City, invented the "vehicle shock absorber repair and sealing machine". Recently, the State Intellectual Property Office issued a utility model patent certificate.

Liu Dongshan was originally an electrical assistant engineer at the Jingmen Beverage Factory. After being laid off, he found that the car shock absorbers are expensive and have a short life. Once they are broken, they can only be replaced with new ones and cannot be disassembled and repaired. After six years of trial and error, he finally solved this problem and filled the gap in the repair of domestic vehicle shock absorbers.

It is understood that the use of the shock absorber repairing machine developed by Liu Dongshan, the cost of repairing a shock absorber is not more than 10 yuan, the maintenance cost is 90% lower than the replacement of the new shock absorber.
