Further, when one element is considered to be a "fixed transmission connection" to another element, the two can be fixed in a detachable connection, or can be fixed in a non-detachable connection, as long as power transmission can be achieved, such as socket connection, snap connection. , integral molding fixing, welding, etc., can be realized in the prior art, and will not be redundant here. When a component and another component are perpendicular or approximately perpendicular to each other, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for the purpose of illustration only and do not represent the only embodiment. 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, when interpreting the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including a margin of error, which should be acceptable for a specific value determined by those skilled in the art. within the deviation range. For example, "about", "approximately" or "substantially" can mean within one or more standard deviations, without limitation.

The technical features of the above embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features It is considered to be the range described in this specification.
