Further, when one element is considered as "fixed transmission connection" with another element, the two elements may be fixed in a detachable connection manner or in an undetachable connection manner, and power transmission can be achieved, such as sleeving, clamping, integrally-formed fixing, welding and the like, which can be achieved in the prior art, and is not cumbersome. When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements are perpendicular, but some vertical error may exist due to manufacturing and assembly effects. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
It should also be understood that in explaining the connection relationship or the positional relationship of the elements, although not explicitly described, the connection relationship and the positional relationship are interpreted to include an error range which should be within an acceptable deviation range of a specific value determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, without limitation.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
