[0023] Example

[0024] Reference Figure 1-4As shown, this utility model discloses a microphone telescopic rod connection structure, including an adjusting tube 10, a bottom tube 20, and a locking sleeve 30. A fastening sleeve 201 is fitted onto the adjusting tube 10, and the fastening sleeve 201 is installed inside the bottom tube 20 and extends upwards from the tube opening. The locking sleeve 30 locks the fastening sleeve 201 onto the adjusting tube 10. Specifically, the fastening sleeve 201 includes two second semi-circular shells 2011, with positioning blocks 2012 provided on the outer walls of the second semi-circular shells 2011. Positioning holes 20 are opened on the side walls of the bottom tube 20. 2. Positioning block 2012 passes through positioning block 2012, so that the two semi-circular shells are installed on both sides of the inner wall of the bottom tube 20. Locking sleeve 30 is fitted into adjusting tube 10. Adjusting tube 10 is inserted from the two second semi-circular shells 2011. The threads on the inner wall of locking sleeve 30 are locked with the threads on the side of adjusting tube 10. Locking sleeve 30 locks and presses the part of the two second semi-circular shells 2011 extending out of the tube opening of the bottom tube 20 into adjusting tube 10, so as to lock and fix adjusting tube 10 in the bottom tube 20.

[0025] Reference Figure 1-4 As shown, an anti-slip sleeve 101 is provided at the bottom of the adjusting tube 10. The adjusting tube 10 is inserted into the bottom tube 20. The anti-slip sleeve 101 includes two first semi-circular shells 1011. An elastic element is installed between the two first semi-circular shells 1011. Specifically, several guide holes are symmetrically opened on the lower side of the adjusting tube 10. Several guide tubes 1012 are provided inside the first semi-circular shells 1011. The guide tubes 1012 pass through the guide holes. The two first semi-circular shells 1011 are installed on the lower side of the adjusting tube 10 through the guide tubes 1012. 1011 can only move horizontally. Furthermore, a semi-circular groove is opened on the outer wall of the first semi-circular shell 1011, and a rubber ring 1014 is set in the semi-circular groove. The rubber ring 1014 binds the two first semi-circular shells 1011 and encircles the two first semi-circular shells 1011, which restricts the distance between the two first semi-circular shells 1011 and pre-presses the first semi-circular shells 1011 against the inner wall of the bottom tube 20, thereby increasing friction and preventing the adjusting rod from falling freely.
