An arc-shaped bulge is formed on the outer side of the acting surface, and when the mounting sheath is mounted between the mounting cavity of the rod and the mounting end of the base, deformation is generated, so that interference fit is formed between the mounting sheath and the mounting cavity of the rod as well as between the mounting sheath and the mounting end of the base; a direct insertion installation mode is adopted, convenience and rapidness are achieved, and after installation, axial and radial displacement and circumferential rotation cannot occur between the rod and the base.

Description

Technical Field

[0001] The utility model relates to an installation sheath. Background Art

[0002] In the current connection technology, the fixing methods of the square rod or polygonal rod and the base mainly include three methods: snap-fit, screw locking and threaded connection. However, each of these methods has its own limitations.

[0003] First, there may be a certain gap in the snap connection, which will cause instability and shaking between the rod and the base. This situation is particularly obvious in application scenarios that require precise fixation or high stability requirements. Secondly, although the screw locking method can provide a relatively strong connection, in some cases, especially when the screws are locked from the side of the rod, it may also cause shaking between the rod and the base. This shaking may affect the stability and service life of the overall structure. Finally, although the threaded connection can fix the rod and the base, it usually cannot accurately control the final direction of the rod. In addition, when the inside of the rod needs to pass through the line, the threaded connection may not be applicable because it may hinder the layout and maintenance of the line.
