[0031] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0032] The fixed connection in the present application refers to the connection of parts or components after being fixed without any relative movement. It is divided into two kinds of detachable connection and non-detachable connection.

[0033] (1) Detachable connection: use screw, spline, wedge pin, etc. to fix the parts together. This connection can be disassembled during maintenance and will not damage the parts. But the specifications of the connecting parts must be correct (such as the length of the bolt, key, wedge pin), and be fastened properly.

[0034] (2) Non-detachable connection: mainly refers to welding, riveting and over mortise fitting, etc. Because it needs to be forged, sawed or oxygen cut to disassemble during maintenance or replacement, so the parts generally cannot be used twice. At the same time, attention should be paid to the process quality, technical detection and remedial measures (such as correction, polishing, etc.) during connection.

[0035] The sliding connection in the present application refers to the sliding of the parts along the linear track, and the hinge in the present application refers to the constrained rotation of the parts along the axial direction.

[0036] In some cases, the sliding connection and hinge in the present application can also have damping, so that the parts have the ability to maintain in the desired position.

[0037] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
