[0024] A connecting head 4 is arranged at the output end of the first pipeline 1 and the output end of the plurality of connecting pipes 3 respectively, and a plurality of locking assemblies 5 are arranged on the connecting head 4, and the number of the locking assemblies 5 is preferably two; the two locking assemblies 5 can be conveniently pressed at the same time;

[0025] Specifically, the locking assembly 5 comprises a groove 51 arranged on the outer surface of the connecting head 4, one end of the groove 51 is fixedly connected with a rotating shaft 52, the locking block 53 is rotatably arranged on the rotating shaft 52, the torsional spring 54 is sleeved on the rotating shaft 52, the torsional spring 54 is arranged to support the locking block 53; the two ends of the torsional spring 54 are inserted into the inside of the limiting sleeve 57, the two limiting sleeves 57 are fixedly connected with the inner side wall of the groove 51 and the inner side wall of the locking block 53 respectively, the limiting sleeve 57 is arranged to limit the torsional spring 54, so that the torsional spring 54 cannot move during use; the end of the locking block 53 away from the rotating shaft 52 is provided with a protrusion 55, one side of the groove 51 is fixedly connected with a pressing block 56 matched with the protrusion 55, the protrusion 55 and the pressing block 56 are arranged to limit the locking block 53, so that the free end of the locking block 53 cannot be separated from the inside of the groove 51.

[0026] A mounting sleeve 6 is arranged at the input end of the second pipeline 2 and the input end of the plurality of connecting pipes 3 respectively, the inner side wall of the mounting sleeve 6 is provided with a mounting groove 7, and the mounting groove 7 is provided with a locking groove 8, the mounting groove 7 and the locking groove 8 are matched, so that the locking block 53 can be quickly locked into the inside of the locking groove 8;

[0027] The connecting pipe 3 is provided with an air pressure sensor 9 for detecting air pressure. The output end of the air pressure sensor 9 is electrically connected to the input end of a controller (not shown in the figure) through a wire, and the output end of the controller is electrically connected to the input end of an alarm (not shown in the figure) through a wire. Through the arrangement of the air pressure sensor 9, the pressure in the conveying pipeline can be detected.
