[0050] Working principle:

[0051] When installing valve body 2, firstly, the auxiliary chuck 503 is moved towards the main chuck 501 to allow them to engage. Then, air is supplied to the push chamber 5011 through the push air passage. The piston 506 moves forward, causing the push rod 504 to move synchronously. The push rod 504 pushes the locking element 502 to extend radially out of the main chuck 501 to lock the auxiliary chuck 503, thereby locking valve body 2 and valve seat 3. At the same time, the push elastic element 505 is compressed and stored. When disassembling, air is supplied to the reset chamber 5012 through the reset air passage. The piston 506 moves backward, causing the push rod 504 to move backward synchronously. The push rod 504 releases the pressure on the locking element 502, and the main chuck 501 and auxiliary chuck 503 are unlocked. The push elastic element 505 resets and pushes the auxiliary chuck 503 away from the main chuck 501.
