[0039] The implementation principle of a socket connection device for flexible pipe connection in an embodiment of the present application is as follows: in actual use, the outer ends of the main pipe part 11 and the auxiliary pipe part 41 are fixedly installed with connecting flanges, ensuring that the main pipe part 11 and the auxiliary pipe part 41 can be connected to the pipe through the connecting flanges during use. When the main pipe part 11 and the auxiliary pipe part 41 are connected to the external pipe, they can be spliced. The angle adjustment is achieved by adjusting the position of the angle swing tube 4 on the double-open ball head shell 3. After adjusting the angle, the middle connecting seat 2 can be inserted into the connecting clamp 12 of the main connecting pipe 1, and the matching clamp plate 222 can be clamped into the positioning clamp seat 13 by rotating the middle connecting seat 2, so that the two can be stably fixed to each other. In order to further increase the safety of the connection, a positioning half hole can be opened on the connecting clamp 12 and the matching clamp plate 222, so that a pin can be inserted between the two for locking, ensuring that the connecting clamp 12 and the matching clamp plate 222 can be locked to each other.
