[0026] The working principle of the present utility model is as follows: During use, first place the control arm on the upper end of the support base 1 for fixation, and use the driving motor 18 to drive the mounting plate 2, the sleeve 3 and the positioning column 17 to move downward. Use the positioning column 17 to position the control arm, so that the part of the control arm with the bushing to be pressed is aligned with the cylindrical cavity 11, which is convenient for the weight pressing sleeve 13 to move downward along the cylindrical cavity 11 to press the bushing into the control arm. A bushing can be placed in each of the five placing holes 5. The bushing is placed above the two baffle plates 7 on the inner side of the placing hole 5. Use the motor 14 to drive one placing hole 5 to be aligned with the cylindrical cavity 11, and then use the electric telescopic rod 12 to drive the weight pressing sleeve 13 to move downward. When the weight pressing sleeve 13 moves downward, it can squeeze the two extrusion blocks 9 at the upper ends of the two baffle plates 7, so that the two extrusion blocks 9 are separated to both sides, and then drive the two baffle plates 7 to separate. At this time, the bushing above the baffle plate 7 can slide downward to the upper end of the control arm. As the weight pressing sleeve 13 continues to move downward, the bushing is quickly pressed in. And when the weight pressing sleeve 13 presses the bushing, bushings can be placed in the other placing holes 5, which reduces the operation time, improves the efficiency of bushing pressing processing, is more convenient to use. After processing one control arm, other control arms can be replaced for processing.
