When in use, the telescopic mechanism 2 can be telescopic to adjust the supporting height; when stored, the telescopic mechanism 2 can be contained in the chassis 1 in a telescopic way.
As shown in fig. 1 to 4, a storage groove 3 is provided on the chassis 1, the telescopic mechanism 2 is rotatably mounted in the storage groove 3, and a locking mechanism 4 is provided between the telescopic mechanism 2 and the storage groove 3. When the telescopic mechanism 2 is used, the locking mechanism 4 is used for locking the telescopic mechanism 2 and the chassis 1; when the telescopic mechanism 2 is stored, the lock mechanism 4 releases the lock between the telescopic mechanism 2 and the chassis 1, and after the lock is released, the telescopic mechanism 2 is turned over with respect to the chassis 1 and stored in the storage groove 3.
Further, as shown in fig. 1 to 4, the telescopic mechanism 2 includes: an inner sleeve 5 and a telescopic rod. The hinged end of the inner sleeve 5 is rotatably mounted to the chassis 1. The fixed end of the telescopic rod is sleeved in the inner sleeve 5 and fixedly assembled with the inner sleeve 5. The telescopic end of the telescopic rod is assembled with electronic equipment or small-sized electric equipment.
Specifically, both sides of the hinged end of the inner sleeve 5 extend outward to form the rotation shafts 11, and the two rotation shafts 11 are arranged on the same axis. The chassis 1 is provided with an accommodating space 9, an installation boss 10 is arranged on the inner wall surface of one side of the accommodating space 9, and installation shaft holes 25 are respectively arranged on the positions, corresponding to the two rotating shafts 11, of the installation boss 10. The size of the installation shaft hole 25 is matched with the size of the two rotating shafts 11, and the two rotating shafts 11 are respectively inserted into the installation shaft hole 25, so that the inner sleeve 5 can be rotatably installed on the installation boss 10 through the rotating shafts 11.
The lock mechanism 4 includes: locking member 6, outer sleeve 7 and limit structure 13.
