[0033] It is to be noted that the relative terms, such as first and second, and the like, are used herein solely to distinguish one from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0034] 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.

[0035] (1) Detachable connection: the parts are fixed together by using screw, spline, wedge pin, etc. This connection mode can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolt, key, wedge pin), and the fastening should be appropriate.

[0036] (2) Non-detachable connection: mainly refers to welding, riveting and over mortise fitting, etc. Since it needs to be forged, sawed or oxygen cut to disassemble during maintenance or replacement, 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.

[0037] The sliding connection in the present application refers to the sliding of the parts along a linear track, and the hinge in the present application refers to the rotation of the parts along the axial constraint.
