One end of the telescopic tube 42 is hinged to the connecting frame 1, and the other end of the telescopic tube 42 is hinged to the trolley. Each connecting tube 421 is sleeved on the periphery of the elastic connection member 41. Specifically, the elastic connection member 41 is used to drive the seat 2 to return to its original position. The original position of the seat 2 is set close to the trolley. When the operator drives the seat 2 to move, the elastic connection member 41 is in a stretched state. After the operator finishes the installation, there is no need to manually restore the position of the seat 2. The operator only needs to leave the seat 2, and the elastic connection member 41 drives the seat 2 to return to its original position. This is not only convenient for the operator to pick up tools next time, but also beneficial to the space optimization of the vehicle body component installation auxiliary device 100, improving the safety of the operation.
