[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a trombone, including a mouthpiece and a draw tube, the draw tube includes an inner draw tube and an outer draw tube, two parallel inner draw tubes are connected by a cross bar, wherein the inner draw tube is provided with a mouthpiece, the outer draw tube includes two connecting tubes, a cross bar, a lower section tube and a U-shaped curved tube, the two connecting tubes are fixedly connected to form mutually parallel outer draw tube upper brackets through the cross bar, the upper ends of two lower section tubes made of carbon fiber material are fixedly connected to the upper bracket after being inserted, and the lower ends of the lower section tubes are fixedly connected to the U-shaped curved tube after being inserted, forming an outer draw tube structure of two materials.

[0005] Furthermore, the wall thickness of the lower tube section is 0.5-1.2 mm.

[0006] Furthermore, both ends of the lower tube section are provided with plug-in round tables, and the plug-in round tables are slidably matched with the upper bracket and the inner diameter of the U-shaped curved tube respectively.

[0007] Furthermore, the lower tube section is fixedly connected to the upper bracket and the U-shaped curved tube by respectively bonding with strong glue.

[0008] Beneficial effects: Compared with the prior art, the utility model greatly reduces the cost of metal materials by replacing metal materials with carbon fiber tube materials. At the same time, replacing metal materials with carbon fiber tube materials not only saves metal materials but also reduces costs. Moreover, the carbon fiber tube materials are light to use, more convenient for users to remember and easy to grasp. The utility model can be applied to trombones of various voices.
