[0040] exist Figures 1 to 4In an optional embodiment, the fixed block 2 also includes a slot 22. The inner joint mechanism 4 includes a first spring 41 and a fixed inner ring 42. The fixed inner ring 42 is hollow and is disposed in the slot 22. One end of the first spring 41 is connected to the fixed block 2, and the other end of the first spring 41 is connected to the fixed inner ring 42. At the same time, a spherical arc surface is provided on the outer surface of the fixed inner ring 42. The spherical arc surface on the fixed inner ring 42 can cooperate with the spherical arc surface on the first limit block 31. The steel ball 8 is located in the spherical arc surface. With the compression of the first spring 41, the fixed inner ring 42 translates along the direction of its axis, and the steel ball 8 rolls on the spherical arc surface of the fixed inner ring 42.

[0041] Furthermore, the fixed inner ring 42 includes a first gas passage 43, and gas can flow into the cylinder from the first gas passage 43. It should be noted that the fixed inner ring 42 is coaxial with the slot 22, and in order to ensure the sealing of the quick installation joint and to ensure that the airflow and lubricating oil do not leak, a third sealing ring 43 is provided between the fixed inner ring 42 and the slot 22.

[0042] exist Figures 1 to 4 In an optional embodiment, the fixing block 2 further has a circular hole 23. The driving mechanism 5 includes a handle 51 and a wear-resistant wheel 52. The driving mechanism 5 is connected to the housing 1, the handle 51 is connected to the wear-resistant wheel 52, the wear-resistant wheel 52 is connected to the inner wall of the circular hole 23, the wear-resistant wheel 52 is eccentrically arranged to the circular hole 23, and when the handle 51 rotates, the wear-resistant wheel 52 rotates around the inside of the circular hole 23, and the wear-resistant wheel 52 pushes the housing 1 to move.

[0043] It should be noted that the handle 51 is annular, and the cylinder is installed between the annular handles 51. When the quick-install connector is working, the annular handle 51 can lock the cylinder to ensure that the quick-install connector fails. When quickly detaching from the cylinder, the annular handle 51 can wrap around the cylinder to avoid secondary injuries caused by accidents.

[0044] exist Figures 1 to 4 In an optional embodiment, the quick-install connector includes a connector body mechanism 6, which is disposed in the gas interface 11, and includes a second gas channel 61, which is connected to the first gas channel 43. Gas flows in from the second gas channel 61 and flows into the cylinder from the first gas channel 43.

[0045] It should be noted that the quick-install connector also includes a safety limit mechanism 7, which is arranged on the shell 1. The safety limit mechanism 7 includes a third air duct 71, a limit rod 72, a second spring 73 and a nut 74. The nut 74 is screwed onto the shell 1, and the limit rod 72 is connected to the nut 74 through the second spring 73. The third air duct 71 is located above the limit rod 72, and the third air duct 71 is connected to the second air duct 61.

[0046] Furthermore, when the quick-install connector is working, when the gas enters from the second air channel 61, it will enter the third air channel 71, and the gas flowing into the third air channel 71 will lift the limit rod 72. Under the action of air pressure, the limit rod 72 squeezes the second spring 73, causing the second spring 73 to deform, thereby extending the limit rod 72 and limiting the movement of the shell 1 along the x-axis direction, ensuring that the quick-install connector will not pop out during operation, thereby protecting the safety of the operator.

[0047] As the previous quick-install connector, optionally, the internal connector mechanism 4 includes a buckle 44 and a second sealing ring 45, the buckle 44 is arranged adjacent to the internal thread, the second sealing ring 45 is arranged on the side of the installation interface 13, and the internal thread and the buckle 44 fix the cylinder.

[0048] The operating steps of a quick installation connector of the utility model are as follows:

[0049] A gap 21 is left between the shell 1 and the fixed block 2, the first limit block 31 is arranged in the gap 21, the outer claw 32 is engaged with the fixed block 2 in the gap 21, and the outer claw 32 has an internal thread. At the same time, the fixed block 2 has a slot 22, and the fixed inner ring 42 is arranged in the slot 22, and the fixed inner ring 42 also has a buckle 44. The cylinder can be fixed to the quick installation joint by the cooperation of the internal thread and the buckle 44. When the quick installation joint needs to be fixed to the cylinder, shake the handle 51 upwards, and the wear-resistant wheel 52 rolls along the inner surface of the circular hole 23, thereby pushing the shell 1 to move to the left along the x-axis direction (see Figure 3 ), the outer claw 32 opens under the pressure of the first sealing ring 33, and the cylinder can be conveniently fixed to the quick-install joint. When the quick-install joint needs to be operated, the handle 51 is shaken downward, and the wear-resistant wheel 52 drives the housing 1 to move to the right along the x-axis direction (see Figure 4 ), the outer claw 32 is recovered into the housing 1, and the cylinder is completely fixed. The housing 1 is driven to move by the handle 51, so that the cylinder is fixed on the quick installation connector, which has a simple structure and improves the convenience of disassembly and assembly.

[0050] By arranging a safety limit mechanism 7 on the shell 1, during operation, driven by the airflow, the limit rod 72 can be extended to ensure that during operation, the shell 1 does not shift to the left in the x-axis direction, avoiding the quick installation connector and the cylinder from falling off, and achieving extremely high safety.

[0051] By setting the handle 51 into a ring shape, when the cylinder is connected to the quick-install connector, the cylinder is located between the ring-shaped handles 51. When the quick-install connector fails and becomes disconnected from the cylinder, the ring-shaped handle 51 can embrace the cylinder to prevent the quick-install connector from flying out due to excessive air pressure, avoid secondary damage caused by the failure, and improve safety during use.
