Description

technical field

[0001] The invention relates to the technical field of automobile safety, in particular to a full-automatic tightening device for heavy-duty vehicle fuel tank straps. Background technique

[0002] With the continuous improvement of my country's automobile technology and the continuous development of highway construction, heavy-duty vehicle transportation has become a trend in the transportation industry, but people's understanding of the maintenance of heavy-duty vehicles is still limited to changing oil and filter elements, often ignoring the need for maintenance of heavy-duty vehicles. Retightening of fuel tank straps. In fact, when the strap is loose, if it is not fastened in time, the sand will enter the gap between the strap and the fuel tank, which will cause excessive wear of the fuel tank, and in severe cases, it will cause oil leakage from the fuel tank, resulting in the failure of the fuel tank. reduced service life.

[0003] According to the maint...
