This allows the vent pipe to be aligned with each hole of the high-mounted brake light. Then, the cylinder controls the vent pipe to descend, and the vent connecting pipe and the sealing connecting pipe are respectively connected to each hole of the high-mounted brake light. The sealing connecting pipe blocks the corresponding hole, and then air is vented through the vent pipe containing the vent connecting pipe to inflate and pressurize the inside of the high-mounted brake light. Then, the air leakage of the high-mounted brake light is detected to complete the air tightness test of the high-mounted brake light. By controlling the movement of the guide block and the slider, the vent pipe can be aligned with the test hole of high-mounted brake lights of different specifications and models. By disassembling and installing the sealing connection pipe and the vent connection pipe, it is easy to select which vent pipe to vent, so as to ensure the air tightness test effect. At the same time, replacing the sealing connection pipe and the vent connection pipe of different sizes can also better adapt to high-mounted brake lights of different specifications and models. This utility model has high versatility and can be adapted to high-mounted brake lights of different specifications and models.
[0008] Preferably, in order to facilitate the disassembly and assembly of the venting connection pipe and the sealing connection pipe, the air inlet end is provided with a connecting part, and the venting connection pipe and the sealing connection pipe are respectively threaded to the connecting part.
[0009] Preferably, in order to ensure the stability of the rotation of the first rotating shaft, a bearing hole is provided on the side plate away from the first motor, a bearing is provided in the bearing hole, and the bearing is mounted on the first rotating shaft. Attached Figure Description
