Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a music teaching is with flexible pole of waving, including dead lever 1, 1 outer wall cover of dead lever is equipped with slipmat 2, both ends all set firmly elastic webbing 3 around the dead lever 1, 1 left end upper side of dead lever is equipped with bolt 4, 1 upside of dead lever is equipped with movable rod A5, movable rod A5 upside is equipped with movable rod B6, telescopic mouth 7 has all been seted up at both ends about movable rod B6, telescopic mouth 7 is inside to be equipped with the

stripper bar

8, 8 middle part downside of two stripper bars are equipped with spring A9, dead lever 1 and movable rod A5 are inside all to have set firmly spring B10, movable rod B6 upside is equipped with knob 11, the 11 lower extreme of knob has set firmly connecting rod 12, the 12 lower extreme of connecting rod has set firmly cam 13.

Specifically, the end of the bolt 4 penetrates through the left end of the fixed rod 1, extends into the fixed rod, and is in pressing contact with the outer wall side of the movable rod a 5. The movable lever a5 can be fixed inside the fixed lever 1 by turning the bolt 4.

Further, the outer wall of the movable rod A5 is in sliding contact with the inner wall of the fixed rod 1, and the outer wall of the movable rod B6 is in sliding contact with the inner wall of the movable rod A5.

Furthermore, two ends of the spring A9 are respectively and fixedly connected with the inner walls of the two extrusion rods 8, and the upper ends of the two springs B10 are respectively and fixedly connected with the lower ends of the movable rod A5 and the movable rod B6. The spring a9 is provided to press the movable lever a5 and the movable lever B6 when the movable lever a5 and the movable lever B6 are in a relaxed state, so that the device can be extended, thereby enabling the device to function as an extension.
