Specifically, the number of the first limiting grooves 41 of the interlocking piece 4 is two, and the two first limiting grooves 41 are respectively corresponding to the first position and the second position of the interlocking piece 4. The two first limit grooves have the similar gear effect, and the interlocking device can be conveniently interlocked or unlocked during rotation. More specifically, the interlocking member 4 is provided with a second limiting groove 42 for preventing the driving shaft 51 from being excessively separated from rotation. The arrangement of the second limit groove prevents the driving shaft or the driving cam from rotating excessively, so that the interlocking structure is unlocked again.

At least two interlocking members 4 are provided, and different interlocking members 4 are mutually matched and arranged around the driving shaft 51 and driven by the driving shaft 51 to move radially towards the driving shaft 51.

Specifically, the unlocking piece formed by the cooperation of the mounting plate and the driving shaft can be in a shape like a T, an inverted T or an I. The utility model takes I-shaped unlocking pieces as an example, namely mounting plates are arranged at two ends of the driving shaft, so that the product is more stable and convenient to assemble, and the utility model is a preferred mode, and can also adopt T-shaped or inverted T-shaped unlocking pieces, so that the structure of the interlocking device can be simplified, but limit structures such as stop shoulders and the like are required to be added on the driving shaft or on the inner walls of the first pipe fitting and the second pipe fitting. In the utility model, the interlocking piece is arranged at the middle position of the I-shaped unlocking piece, namely, between the mounting plates at the two ends of the I-shaped unlocking piece. When the interlocking piece is positioned at the third position, the guide block is driven to be pressed into the yielding groove by swinging, and the guide block is separated from the yielding groove through the guide inclined surface during unlocking, so that the unlocking of the product is convenient and reliable.
