Symmetrically fixed to the outer wall of the main frame tube 1 are limiting components 5. When this frame tube is in use, a handlebar frame is installed through the connecting tube 2, and an aluminum battery is inserted into the interior of the frame tube 4, so that the aluminum battery is installed on the main frame tube 1. Among them, the limiting components 5 can fix the connecting wires on the aluminum battery, making the connecting wires fit on both sides of the main frame tube 1, and it is convenient to disassemble and assemble the connecting wires, facilitating people to repair the connecting wires.

[0020] The limiting component 5 includes a fixed clamp 6 and a cover 7. The cover 7 covers the interior of the fixed clamp 6. Fixedly connected inside the fixed clamp 6 is a fastening bolt 8. Inside the cover 7 is provided a jack 9. One end of the fastening bolt 8 passes through the interior of the jack 9 and is threadedly connected with a fastening nut 10. Inside the fixed clamp 6 is provided a circular groove. The connecting wire is wound around the outer side of the fastening bolt 8, and both ends of the connecting wire pass through one side of the fixed clamp 6. The connecting wire of the aluminum battery is wound around the outer side of the fastening bolt 8, and the connecting wire also fits and connects with the inner wall of the circular groove on the fixed clamp 6. The cover 7 is covered inside the fixed clamp 6, and the fastening bolt 8 passes through the interior of the jack 9. A fastening nut 10 is tightened on one end of the fastening bolt 8. The fastening nut 10 squeezes the cover 7 to move towards the connecting wire, and the cover 7 can clamp the connecting wire, so as to install two groups of symmetric connecting wires on both sides of the main frame tube 1. When disassembling the connecting wire, only need to unscrew the fastening nut 10 and take out the cover 7 from the interior of the fixed clamp 6, then the connecting wire can be drawn out from the interior of the fixed clamp 6. After the connecting wire is detected, the two groups of connecting wires can be installed on both sides of the main frame tube 1 again in the above manner, and it can be seen that the limiting component 5 can be recycled, avoiding the problem of waste caused by using plastic cable ties.
