When the cavity unit 11 is completely inserted, the limiting spring 25 pushes the limiting ball head 23 to snap into the arc-shaped groove to fix the cavity unit 11. When removing the cavity unit 11, pull the cavity unit 11 outwards with force, and the limiting ball head 23 is compressed into the limiting cavity 24 to release the fixation. This pulling force requires the user to pull hard to achieve.

[0037] By providing the connection assembly, the elastic force of the limiting spring 25 is used to push the limiting spring 25 to fix the cavity unit 11, and the increase and decrease of the cavity unit 11 can be quickly realized, with convenient operation.

The limit ball head 23 is compressed into the limit cavity 24 under pressure, and the limit spring 25 is compressed. When the cavity unit 11 is completely inserted, the limit spring 25 pushes the limit ball head 23 to snap into the arc-shaped groove to fix the cavity unit 11. Insert the connecting pipe 13 into the corresponding moving groove 14, and then push the corresponding push button 21 according to the position of the inserted air hole 12 to move the closing plate 15 to one side, so that the air hole 12 communicates with the cavity 6. Then, rotate the threaded rod 17 to adjust the position of the positioning rod 19 according to the position of the positioning hole opened on the mold. Then hold the handle 5, and the external gas control unit sucks air to form a negative pressure inside the cavity 6 to suck up the diaphragm. Then insert the positioning rod 19 into the positioning hole to complete the positioning. Press down the device, and the diaphragm enters the cavity. Then the external gas control unit deflates to release the adsorption of the diaphragm. When removing the cavity unit 11, pull the cavity unit 11 outwards forcefully. The limit ball head 23 is compressed into the limit cavity 24 to release the fixation. This pulling force requires the user to pull forcefully to achieve.
