Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a sacculus is apart from adjustable quick exchange sacculus expansion pipe, includes injection head 1, and the one end of injection head 1 is provided with first pipe 2, and first spout 7 has been seted up to the one end of first pipe 2, and the inside sliding connection of first spout 7 has hollow second pipe 3, and the one end of keeping away from injection head 1 on the second pipe 3 has been seted up a plurality of notes liquid holes 5, and the outside cladding of annotating liquid hole 5 has sacculus 4, and the tip of second pipe 3 is provided with probe 6. A sealing ring 8 is sleeved between the second guide pipe 3 and the first chute 7. A first liquid injection port 12 is formed in the outer side of the injection head 1, a second sliding groove 9 is formed in the first guide pipe 2, a first liquid conveying pipe 10 is connected in the second sliding groove 9 in a sliding mode, and two ends of the first liquid conveying pipe 10 are communicated with the second guide pipe 3 and the first liquid injection port 12 respectively. A second liquid injection port 13 is arranged on the side surface of the injection head 1, a second liquid conveying pipe 11 is arranged in the first guide pipe 2, and two ends of the second liquid conveying pipe 11 are respectively communicated with the first sliding groove 7 and the second liquid injection port 13.
