The cone structure of end face, the larger end face of top installation component 1 are fixed with turntable 16, and less end face is fixed with locating piece 2 to be connected
Connect.Locating piece 2 is fixed on the end of top installation component 1 by the 3rd screw 13 and pin a 14.The end face of turntable 16 is circumferentially square
To key 8 provided with keyway, is provided with top installation component 1 with keyway correspondence position, turntable 16 passes through keyway with top installation component 1
Coordinate with key 8 spacing.T-shaped piece 7 is additionally provided with the end face of turntable 16, T-shaped piece of 7 centers are provided with screwed hole, and top installation component 1 is with turning
It is threadedly coupled between platform 16 by the first screw 6 with T-shaped piece 7.
The top center of installation component 1 is provided with cavity, and the center of locating piece 2 is provided with for top 3 through holes stretched out, cavity and through hole
The passage for top 3 stretching motion is formed, top 3 stretching motion is arranged in passage.Distributing shaft 10 is arranged in turntable 16, point
It is fixedly connected with the one end of axle 10 with swinging quick-release connector 11, inlet channel 21, inlet channel 21 and cavity is set in distributing shaft 10
It is connected, the end of locating piece 2 is provided with two gas cautious 20, and two gas cautious 20 are in 90 ° of angles, and each gas cautious 20 includes one
The individual corresponding gas inspection passage 22 for being used to connect cavity and gas cautious 20.
Top installation component 1 is provided with the axial limiting chamber connected with cavity towards one end of turntable 16, axial limiting chamber
Internal diameter is more than cavity inside diameter.Distributing shaft 10 is more than remainder, and the position and turntable 16 towards top 3 one end outer end diameter
Between realized by the axle sleeve 9 that is set on distributing shaft 10 it is radially spacing.The end of distributing shaft 10 is provided with the second limited block 26, and second
The one end of limited block 26 and the spacing cooperation in end face of turntable 16, the other end and the spacing cooperation of axial limiting chamber, so as to which axle clamp will be distributed
Tightly, and it is limited in turntable 16.Second top installation component 26 of distributing shaft 10 is provided with screwed hole, top installation component 1 with
Distributing shaft 10 is threadedly coupled by the second screw 12 through screwed hole.It is provided with and is used for top in the cavity of top installation component 1
The annular step tread 23 of sharp 3 axial limitings, top 3 end are provided with the first limited block 24 with the 23 spacing cooperation of annular step tread.
Spring 4 is additionally provided with the cavity of top installation component 1, pad 5, the other end of spring 4 are provided between spring 4 and the end of distributing shaft 10
With top 3 elastic connection.
Top 3 are in axial direction provided with for the groove with cavity gas connection, the interior setting of the top side wall of installation component 1
Gas inspection passage 22 both ends are connected with the groove gentle cautious 20 respectively.Top 3 are provided with sealing ring 25, and the sealing ring 25 is with stretching
