It will be appreciated that the second gas inlet 1231 is not opened and fed with gas only in the unlocked state, but is simultaneously opened with the first gas inlet 111 and the second gas inlet 1231, and gas is fed at the same time, when the gas of the first design pressure fed from the first gas inlet 111 drives the first moving assembly 30 to move to the accommodating groove 310 and communicate with the second limiting groove 421, the gas of the second design pressure provides a certain driving force to the limiting member 20, and drives the limiting member 20 to move out of the second limiting groove 421, so that the separating device 100 is converted into the unlocked state. The embodiment of the application can almost simultaneously complete unlocking and separating after simultaneously air intake through a simple structure, realizes the integration of pneumatic unlocking and pneumatic separating, and has low cost and strong realizability.

In some possible embodiments, referring to fig. 1, the first assembly 10 includes a cylinder 11 and a sleeve 12. The sleeve 12 includes a bottom wall 123, and first and second side walls 124, 125 that are disposed from the outside to the inside. The first limiting groove 1251 is disposed on the second sidewall 125.
The cylinder 11, the first side wall 124, the second side wall 125 and the bottom wall 123 enclose a first accommodating cavity 121, and the first air inlet 111 is formed at the cylinder 11.
The second side wall 125 and the bottom wall 123 enclose a second accommodating cavity 122, and the second air inlet 1231 is disposed at the bottom wall 123.
In this embodiment, one side of the bottom wall 123 of the sleeve 12 is connected with a first side wall 124 and a second side wall 125, the first side wall 124 is coaxially sleeved outside the second side wall 125, a certain space is provided between the first side wall 124 and the second side wall 125, one ends of the first side wall 124 and the second side wall 125 far away from the bottom wall 123 are all connected with the cylinder 11, the space formed among the inner wall of the cylinder 11, the first side wall 124, the second side wall 125 and the bottom wall 123 is a first accommodating cavity 121, the first moving assembly 30 is accommodated inside, and the first air inlet 111 is opened on the cylinder 11. The first gas inlet 111 has a smaller caliber, and when the first gas inlet 111 inputs the gas with the first design pressure, the first moving assembly 30 is pushed to move, and the first moving assembly 30 has a larger volume and is difficult to separate from the first gas inlet 111. Thus, the first mobile assembly 30 of the present embodiment remains within the first assembly 10 after the separation operation of the separation device 100, facilitating recovery during the surface test.
Alternatively, the sleeve 12 is a cylindrical sleeve 12, and has two circumferential surfaces inside, wherein the first sidewall 124 is a circumferential surface of the outer ring, and the second sidewall 125 is a circumferential surface of the inner ring.

In the locked state, one end of the first moving assembly 30 is close to the first air inlet 111. One end of the second moving assembly 40 is adjacent to the second air inlet 1231.
In the unlocked state, gas having a second design pressure drives the second moving assembly 40 through the second gas inlet 1231 to move to be separated from the first assembly 10 at least in part through the separation outlet 112.
In this embodiment, the second moving assembly 40 is locked with the sleeve 12 by the limiting member 20 in the early stage, when one end of the first moving assembly 30 receives the gas with the first design pressure from the first gas inlet 111, the first moving assembly 30 moves to enable the limiting member 20 to have a certain moving space, the second moving assembly 40 receives the driving force of the gas with the second design pressure, so that the limiting member 20 is pressed to move towards the accommodating groove 310 of the first moving assembly 30, and is separated from the limiting groove of the second moving assembly 40, so that the second moving assembly 40 is unlocked. After the second moving unit 40 is unlocked, the second moving unit is driven by the gas at the second design pressure from the second gas inlet 1231, moves toward the separation outlet 112, and is separated from the second accommodating chamber 122 from the separation outlet 112, and is further separated from the first unit 10.
Alternatively, the separation outlet 112 is formed on the cylinder 11 or the sleeve 12, which is not required here, and may be designed according to practical situations, only the second moving assembly 40 is required to be able to separate from the second accommodating cavity 122.
In some possible embodiments, the sleeve 12 has a first air inlet 111 at one end and is detachably connected to one end of the cylinder 11 at the other end.

The side wall of the pressing block 31 seals the first limit groove 1251. The end of the pressing block 31 away from the first piston 32 abuts against the end of the elastic member 50 away from the bottom wall 123.
The gas with the first design pressure drives the first piston 32 and the pressing block 31 to move through the first gas inlet 111, so that the accommodating groove 310 is communicated with the first limiting groove 1251, and the limiting piece 20 is separated from the second limiting groove 421 through the first limiting groove 1251 and moves into the accommodating groove 310 at least partially to be switched to the unlocking state.
In this embodiment, the pressing block 31 plays a role of blocking the first limiting groove 1251 in the locking state, so that the limiting piece 20 is transversely placed in the first limiting groove 1251 and the second limiting groove 421, and the second moving assembly 40 and the second side wall 125 are in a relatively static state. Then, the first piston 32 is driven to move by the gas with the first design pressure, and then the pressing block 31 contacted with the first piston 32 is driven to move, the pressing block 31 is changed from a state of blocking the first limiting groove 1251 to a state that the accommodating groove 310 of the pressing block 31 is communicated with the first limiting groove 1251, so that the limiting piece 20 has a certain movable space, slides out from the second limiting groove 421, and the limiting piece 20 is separated from the second moving assembly 40, so that the second moving assembly 40 is unlocked.

4. In some embodiments, the press block 31 functions to block the first limit slot 1251 in the locked state such that the limiter 20 is disposed transversely within the first limit slot 1251 and the second limit slot 421, and the second moving assembly 40 is in a relatively stationary state with respect to the second sidewall 125. Then, the first piston 32 is driven to move by the gas with the first design pressure, and then the pressing block 31 contacted with the first piston 32 is driven to move, the pressing block 31 is changed from a state of blocking the first limiting groove 1251 to a state that the accommodating groove 310 of the pressing block 31 is communicated with the first limiting groove 1251, so that the limiting piece 20 has a certain movable space, slides out from the second limiting groove 421, and the limiting piece 20 is separated from the second moving assembly 40, so that the second moving assembly 40 is unlocked.
