A blocking block 9 is provided on one side of the four sets of push rods 15. A spring A14 is provided on the outer sleeves of the four sets of push rods 15. Fixed rods 26 are provided at both ends of the two sets of splints 8 away from each other. The outer sides of the two groups of fixed rods 26 on the same side are jointly sleeved with a push plate 7 that cooperates with the push rod 15. A three-pronged pipe 4 is provided on one side of the flow channel 21. The three-pronged pipe 4 is connected to the two groups of push rods 15 on the left side. The inner sides of the two groups of push rods 15 are provided with air guide tubes connected to their three-pronged pipes 4, and one side of the air guide tube passes through the inner sides of the two groups of blocking blocks 9, which can guide the detection airflow and inject the airflow into the flow channel plate. An electric push rod 2 is provided at the bottom of one side of the two groups of side plates 3, and the output ends of the two groups of electric push rods 2 are connected to the push plate 7.

[0026] Furthermore, the prompt component includes a reminder light 16, a guide hole 17, an electric contact block A18, an electric contact block B20, a piston 22, a guide rod 23 and a spring B25. A reminder light 16 is provided on the top of the piston cylinder 24, a guide hole 17 is opened on the top of the inside of the piston cylinder 24, a guide rod 23 is slidably inserted into the inner side of the guide hole 17, a piston 22 adapted to the piston cylinder 24 is provided at the bottom of the guide rod 23, a spring B25 is provided on the top of the guide rod 23, an electric contact block A18 is provided on one side of the top of the piston cylinder 24, and an electric contact block B20 matched with the electric contact block A18 is provided on one side of the top of the piston 22. The reminder light 16 can be used to remind the staff, so that the staff can judge whether the air tightness of the flow channel plate is qualified.

[0027] Furthermore, a bolt is provided on the top of the guide block 12, and a nut is threadedly connected to the outer side of the bolt. A through groove is provided on the top of the guide groove 13 to match the bolt, which can fix the position of the blocking block 9 and facilitate the blocking of the flow channel plate pipe opening.

[0028] Furthermore, a stopper is provided on one side of the outer side of the push rod 15 , and the diameter of the stopper is larger than the spring A14 . When the push rod 15 moves, the spring A14 can be pushed to be compressed, thereby facilitating the reset of the push rod 15 .

[0029] Working principle: When the device is in use, the automobile flow channel plate can be placed on the top of the base 1. At this time, according to the position of the flow channel plate pipe orifice, the staff can slide the bolt on the top of the guide block 12 to adjust the position of the blocking block 9. After the blocking block 9 is moved to the position corresponding to the flow channel plate pipe orifice, the bolt can be rotated to lock the guide block 12, so that the blocking block 9 cannot move. At this time, the two sets of electric push rods 2 are started to push the two sets of clamping plates 8 to approach each other to clamp the flow channel plate. When the clamping plates 8 are clamped on both sides of the flow channel plate, the pipe orifices on both sides of the flow channel plate can be inserted into the inner side of the blocking block 9. At this time, the push plate 7 can continue to push the push rod 15 to overcome the elastic force of the spring A14 to move, so that the blocking block 9 can be inserted into the flow channel plate pipe orifice for blocking.

[0030] After the flow channel plate is sealed, the air pump 5 can be started to operate. The air can be extracted through the air pump 5, enter the flow channel 21 through the guide of the connecting pipe 19, and then enter the guide of the three-pronged pipe 4 into the two sets of push rods 15, and the air is transported into the flow channel plate through the air guide pipe. As the air flow is gradually transported into the flow channel plate, when the flow channel plate is full of air, the air pressure continues to increase, and can enter the piston cylinder 24, and the air pressure pushes the piston 22 to overcome the elastic force of the spring B25 and move upward. When the electric contact block B20 contacts the electric contact block A18, the reminder light 16 can be started to remind the staff, proving that the air tightness of the flow channel plate is qualified;

[0031] If the air tightness of the flow channel plate is unqualified, the air flow will leak outwards and the air pressure will be insufficient, so the warning light 16 cannot be started, which can quickly determine whether the flow channel plate is qualified.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
