[0002] At present, when connecting pipe fittings and pipes, more and more people use the crimping method to achieve the connection between the two. After one end of the pipe is inserted into the end of the pipe fitting and the crimping tool presses the socket of the pipe fitting, the inner circumferential wall of the sealing ring located on the inner side of the end of the pipe fitting can be tightly sealed with the outer circumferential wall of the pipe, and the socket of the pipe fitting can clamp the pipe, that is, the pipe fitting and the pipe are fixed and circumferentially sealed.

[0003] During the pipe production process, the sealing ring needs to be installed in the sealing ring groove located on the inner side of the pipe end. Currently, the process of installing the sealing ring in the sealing ring groove on the inner side of the pipe end is completed manually. Since the sealing ring groove is located on the inner side of the pipe end, the manual assembly of the sealing ring has the disadvantages of inconvenient assembly, low sealing ring installation efficiency and high labor cost.
