Precise sheet metal part convenient to install

The utility model discloses a precise sheet metal part convenient to install, which comprises a fixing plate A and a fixing plate B. An electric roll shaft for driving a limiting rope to roll is fixed on one side of the fixing plate A through a bolt, a connecting plate is adhered to one end, far away from the electric roll shaft, of the limiting rope, and a fixing rod for driving a threaded rod to rotate is arranged on one side of the connecting plate. The outer side of the threaded rod is in threaded connection with a connecting sleeve driving the pressing plate to move longitudinally, and a rubber pad for improving friction between the pressing plate and the sheet metal part body is bonded to the inner side of the pressing plate. The device solves the problems that according to an existing sheet metal part, a sheet metal part body is inconvenient to install, meanwhile, the distance between a fixing plate A and a fixing plate B cannot be adjusted according to the length of the sheet metal part body, and use
