The linkage rod 303 is driven to move through the linkage plate 302, thereby driving the linkage frame 304 and the first pin 305 to move. This allows the first pin 305 to be inserted and fixed. Furthermore, using the above structural arrangement, when the double-outlet cylinder 301 extends, the first pin 305 is in a retracted state, and when the double-outlet cylinder 301 retracts, the first pin 305 is in an extended state. In this way, when the first pin 305 is in an extended and inserted state for a long time, the telescopic shaft of the double-outlet cylinder 301 retracts into the cylinder body, avoiding the problem of the telescopic shaft being easily damaged due to long-term exposure to the outside.

[0033] The side of the linkage frame 304 is provided with a first spring 307, and the other end of the first spring 307 is provided with a sleeve 306, which is provided on the fixed connector 1.

[0034] By setting the first spring 307, the first spring 307 plays a supporting and limiting role on the linkage frame 304, so that the linkage frame 304 is always pushed outward, so that the first plug 305 remains in the extended state in the normal state, and the structure can make the first plug 305 long-term stable installation, and the double oil cylinder 301 does not need to work long-term, so that the double oil cylinder 301 only works when it needs to retract the first plug 305, reduces the working frequency of the double oil cylinder 301, and improves its service life, in addition, the first spring 307 can also stabilize the position of the linkage frame 304, avoiding the problem of sliding of the first plug 305 due to vibration factors during equipment use.

[0035] The second plug-in component 7 includes a second plug 701 which penetrates the third connecting plate 6 and is in sliding fit with the third connecting plate 6, the side surface of the second plug 701 is provided with a second spring 702 connected to the inner side of the third connecting plate 6, the tail end of the second plug 701 is provided with a wedge-shaped slot 703, the wedge-shaped slot 703 is provided with a wedge-shaped frame 704 matched in shape, and the wedge-shaped frame 704 is connected with a single-shaft oil cylinder 705, and the single-shaft oil cylinder 705 is connected to the side surface of the third connecting plate 6.

[0036] By setting the second spring 702 and the wedge-shaped frame 704, the second spring 702 can limit the second plug 701 by using its own elastic force, so that the second plug 701 remains in the plug-in state in the normal state, and avoids the problem of loosening during use, and the wedge-shaped frame 704 can move transversely under the push of the single-shaft oil cylinder 705, and press the second plug 701 by using the wedge-shaped slot 703, so that the second plug 701 is pushed inward, so that it is retracted and unplugged, and the structure achieves the above-mentioned purpose, which is compact, can be completely installed on the inner side of the third connecting plate 6, and does not affect the rotation of the third connecting plate 6, and the single-shaft oil cylinder 705 only extends and works when retracting the second plug 701, so that the single-shaft oil cylinder 705 remains retracted in long-term fixed work, avoiding the problem that the telescopic shaft is easily damaged when exposed to the outside for a long time, and the working frequency of the single-shaft oil cylinder is low, which can increase its service life.

[0037] Working principle: when the rotary oil cylinder 10 is installed, the double oil cylinder 301 moves the linkage frame 304 through the linkage plate 302 and the linkage rod 303, the linkage frame 304 drives the first plug 305 to retract into the first connecting plate 4, and the first spring 307 is in a compressed state under the extrusion of the linkage frame 304, then the second connecting plate 5 is attached to the outer side of the first connecting plate 4 through the rotary oil cylinder 10, then the double oil cylinder 301 is depressurized, the first spring 307 loses the extrusion force, and then releases its elastic force to push the first plug 305 through the linkage frame 304, so that the first plug 305 is plugged with the second connecting plate 5;

[0038] When it is needed to fix the first quick connector 9 or the second quick connector 13, the single-axle oil cylinder 705 pushes the wedge-shaped frame 704 to move, the wedge-shaped frame 704 extrudes the second plug 701 through the wedge-shaped slot 703, so that the second plug 701 is retracted into the third connecting plate 6, and the second spring 702 is compressed, then the fourth connecting plate 8 is attached to the outer side of the third connecting plate 6, then the single-axle oil cylinder 705 is depressurized, the second spring 702 releases the elastic force to push the second plug 701 out, so that the second plug 701 is inserted with the fourth connecting plate 8.

[0039] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this.
