The outer walls of the two connecting plates 7 are provided with threaded holes 8, and The outer wall of the sleeve body 2 is provided with two sets of threaded holes 3. At this time, the telescopic distance of the sleeve is adjusted according to the specific use requirements. Then, two screws 9 are rotated into the threaded holes 8. At the same time, according to the distance after the sleeve is telescoped, two screws 9 are selected to be inserted into two of the two sets of threaded holes 3 to strengthen the connection between the sleeve body 1 and the sleeve body 2.
