The double-headed adjusting bolt 7 is pre-installed on the radar bracket 6, and the electric screwdriver position sensing device 4 is fixedly installed on the frame 1, and the electric screwdriver position sensing device 4 can sense the height position of the downward pressure type electric screwdriver 3 during the bolt locking process. The electric screwdriver position sensing device 4 is electrically connected and communicated with the controller 5. The electric screwdriver position sensing device 4 can transmit the height data of the downward pressure type electric screwdriver 3 during the bolt locking process to the controller 5. The controller 5 can determine whether the double-headed adjusting bolt 7 is locked in place according to the data provided by the electric screwdriver position sensing device 4. The controller 5 controls the power supply circuit and the air supply line to realize the start and stop control of the downward pressure type electric screwdriver 3.

[0018] During assembly, first place the radar bracket 6 into the radar bracket positioning carrier 2 for fixed positioning, then place the double-headed adjusting bolt 7 into the screw hole of the radar bracket 6 for pre-installation, and hold the downward-pressure electric screwdriver 3 to press down and assemble the double-headed adjusting bolt 7. When the double-headed adjusting bolt 7 is assembled to the set height, the electric screwdriver position sensing device 4 senses that the height of the downward-pressure electric screwdriver 3 has reached the designed height. The electric screwdriver position sensing device 4 gives a signal to the controller 5, and the controller 5 cuts off the gas source and power supply of the downward-pressure electric screwdriver 3, and the downward-pressure electric screwdriver 3 automatically stops working. After assembly is completed, the assembly height of the double-headed adjusting bolt 7 can be guaranteed, and the mechanism has high efficiency in assembling the double-headed adjusting bolt 7 for the radar bracket 6, low labor intensity for workers, and saving assembly costs.

[0019] A go / no-go gauge mounting frame 8 is also fixedly installed on the frame 1, and the go / no-go gauge mounting frame 8 is arranged on one side of the radar bracket positioning carrier 2.
