When the relative position between the plug-in part 12 and the plug-in part 21 needs to be adjusted, the locking piece 38 is pressed, the sliding piece 37 moves towards the inside of the basket-shaped piece 121, the locking piece 38 is separated from the pressing piece 214, the plug-in part 21 is moved to adjust the position, after the position adjustment is finished, the external force is removed, the sliding piece 37 moves towards the outer side of the basket-shaped piece 121 under the action of the second elastic piece, the locking piece 38 is made to contact again and press the pressing piece 214, the pressing piece 214 receives the force of the third elastic piece for moving the pressing piece inwards while moving outwards, after the elastic forces of the second elastic piece and the third elastic piece are balanced, the pressing piece 214 and the locking piece 38 are pressed and the position is kept stable, and the plug-in part 12 and the plug-in part 21 are kept at the adjusted position under the friction force between the pressing piece 214 and the locking piece 38.

In the embodiment 2, the limiting sleeve 23 is not arranged, and correspondingly, the auxiliary supporting sheet 4 is directly and rotatably connected to the second component 2 through a rotating shaft (see fig. 15).

The sliding piece 37 can be made of plastic materials, and the whole structure is lighter. The sliding element 37 and the pressing piece 214 are in a mutual pressing state for a long time, and in order to increase the service life of the sliding element 37, a structural element made of metal can be added in the sliding element 37 to enhance the strength of the sliding element 37. The pressing piece 214 may be made of metal.
