The structure is complex and the process of assembling the sliding assembly is cumbersome. The present technical solution can effectively avoid the above defects.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
