Air tightness detector valve terminal with multiple channels

The utility model discloses an air tightness detector valve terminal with multiple channels, relates to the technical field of valve terminals, and aims to solve the technical problems that in the prior art, in the using process of an air tightness detector, air tightness detection needs to be carried out on more products, and when the number of the products exceeds the output channel quantity of the valve terminal, the air tightness detection is inconvenient. Generally, products are carried out in batches or an original valve terminal is replaced by a valve terminal with more output channels, so that the operation is troublesome, and the air tightness detection efficiency of the products is influenced. An auxiliary confluence plate is arranged on one side of the confluence plate, an air cavity is formed in the confluence plate, an inserting hole is formed in one side of the interior of the confluence plate and communicates with the air cavity, an inserting pipe head is arranged in the inserting hole and fixe
