Therefore, through the arrangement of the sliding module, when the power source pushes the push pipe to move upwards, on one hand, the push pipe can move upwards smoothly, and then the sealing element is compressed to expand; on the other hand, the bending of the joint of the push pipe and the power source caused by excessive stress of the push pipe multiple-time compression sealing element can be avoided.

Still further, the bottom plate supporting mechanism comprises a fixing plate, a height adjusting plate and an adapter plate, the fixing plate is fixed on the equipment workbench, the height adjusting plate is fixed on the fixing plate, the power source is arranged on the height adjusting plate, the adapter plate is arranged on the power source, and the bottom plate is matched with the adapter plate. It is thus clear that the bottom plate cooperatees with the keysets, that is to say fixed module setting is on bottom plate supporting mechanism, through the setting of fixed plate, can make the utility model discloses fix well on the equipment workstation. In addition, the height position of the power source can be adjusted through the height adjusting plate, so that the distance between the push pipe and the connector channel is within a proper range, the power source provides power to push the adapter plate and further push the sealing element pushing and pressing mechanism, and the power source on the fixed block provides power to push the push pipe to compress the sealing element to deform and expand after the push pipe is in place.

Still further, the power source includes three cylinders, three cylinders respectively with the left push tube, the right push tube and the keysets transmission connection, little push tube with the right push tube with same cylinder transmission connection. Therefore, the air cylinder can provide power to push the adapter plate, the left push pipe, the right push pipe and the small push pipe.

Still further, the sealing member and the small sealing member both adopt sealing silica gel. Therefore, the sealing silica gel has the advantages of strong adhesiveness, moisture resistance, water resistance and aging resistance, so that the through hole of the connector can be well plugged, and the service life is long.
