[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. It can be categorized into two types: detachable connection and non-detachable connection.

[0035] (1) Removable connection: Components are fastened together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0036] (2) Non-detachable connections: These mainly refer to welding, riveting, and tenoning. Since parts must be forged, sawed, or oxygen-cut for disassembly during repair or replacement, they are generally not reusable. Furthermore, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration and polishing) during connection.

[0037] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinged connection referred to in this application means that the component can rotate along an axial constraint.

[0038] In some cases, the sliding connections and hinges referred to in this application may also be damped so that the components have the ability to maintain a desired position.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
