Through the above, if the device becomes loose during working, the adjusting ring 4 and the second connecting port 6 are relatively close to each other, so that the sealing performance is improved, the air pressure in the conveying pipe is stabilized, and the feed is prevented from being broken under the fluctuation of the air pressure; when the device needs to be disassembled, the device can only be in a stop state (the induction part 5 is not in an action state), at the moment, the adjusting ring 4 and the second connecting port 6 are relatively far away, the sealing pretightening force is weakened, and the interface device 17 can be disassembled.
In setting the parameters, the following settings may be made, for example: when the induction element 5 does not move outwards, the diameter ratio of the friction wheel 51 to the induction column 54 is equal to or smaller than the distance ratio between the contact part of the friction wheel 51 and the friction disc and the contact part of the induction column 54 and the synchronizing ring 32 to the pipe axis, the inclination of the first smooth ramp 22 and the second smooth ramp 41 is twice of the pitch of the connecting flange 21 and the accommodating pipe 61, and the induction element 5 can move outwards by L (the size of the L is consistent with that the diameter ratio of the contact part of the friction wheel 51 and the friction disc after moving outwards by L and the radius ratio of the contact part of the induction column 54 and the synchronizing ring 32 to the pipe axis is larger than the diameter ratio of the friction wheel 51 to the induction column 54). Another example is: when the sensing element 5 is not moved outwards, the diameter ratio of the friction wheel 51 to the sensing column 54/the diameter ratio of the radius ratio of the contact part of the friction wheel 51 to the friction disc and the radius ratio of the contact part of the sensing column 54 to the synchronous ring 32 relative to the pipe axis is 1/2, the inclination of the first smooth sloping platform 22 and the second smooth sloping platform 41 is three times of the pitch of the connecting flange 21 and the accommodating pipe 61, and the sensing element 5 can be moved outwards L (both sizes are suitable), so that the above result can be achieved. Naturally, there are other embodiments that achieve the above result by properly setting the relationship between the above variables.

With the above embodiment, the use principle and the working process of the present invention are as follows:
when the interface device 17 is attached, the first connection port 2 and the second connection port 6 are relatively rotated until the first seal ring 42 and the second seal ring 63 come into contact with each other and are slightly compressed, and the connection is tightened. At this time, the first smooth ramp 22 and the second smooth ramp 41 are tightly fitted, as shown in fig. 9, the inner surface of the sensing post 54 and the inner peripheral wall surface of the adjusting ring 4 are in a tangent position (an initial position, the sensing post 54 may slightly extend into the adjusting ring 4 or be in other positions between the reserved opening and the inner peripheral wall surface of the adjusting ring 4), the friction wheel 51 is in contact with the friction plate 62, and the synchronizing ring 32 is in contact with the sensing post 54, which are both in friction fit.
