In the actual product, the adapting portion 32 and the fixing portion 31 may be provided separately and connected to each other, or may be directly connected or through an intermediate member.

In the setting details of the fixing portion 31, referring to an embodiment, the fixing portion 31 includes a plugging cavity 311 with a semi-closed structure, the shape of the inner space of the plugging cavity 311 is mutually matched with the distal end side of the pressure cylinder 1, and the fixing portion 31 is axially abutted against and circumferentially limited by the plugging cavity 311 and the pressure cylinder 1.

The plugging cavity 311 can provide a stable connection link and realize a basic positioning effect. In this embodiment, axial limitation is achieved by plugging the two, circumferential limitation can be achieved by optimizing the shapes of the two, and in the embodiment shown in the drawings, the distal end side of the pressure cylinder 1 is provided with an axially extending plugging strip 12, a plugging groove 312 corresponding to the plugging strip 12 is arranged in the plugging cavity 311, and after the plugging strip 12 and the plugging groove 312 are corresponding in place, a fastening member 313 penetrates through the side wall of the plugging cavity 311 via the outer side of the fixing part 31 to be connected with the plugging strip 12.
