The lateral swinging member 21 can swing laterally relative to the traction rod 1. The connecting member 22 is connected to the lateral swinging member 21. The connecting member 22 is used to connect the seat support rod of a large-sized bicycle.

[0026] In the utility model, by arranging the first connection assembly 2 and the second connection assembly 3 at both ends of the traction rod 1, the first connection assembly 2 is used to connect the large-size bicycle, and the second connection assembly 3 is used to connect the small-size bicycle, so that the two bicycles can be connected together, and the parent can lead the direction in front when the parent and child ride, which improves the safety of the parent-child riding; at the same time, the lateral swinging member 21 of the first connection assembly 2 can swing laterally relative to the traction rod 1, and when the large-size bicycle in front turns, the lateral swinging member 21 also swings accordingly, which improves the flexibility when turning and is safer.

[0027] In some embodiments, Figure 2 As shown, the connecting member 22 includes a first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 is connected to the lateral swinging member 21, and the second connecting portion 222 is detachably connected to the first connecting portion 221. Specifically, in this embodiment, the first connecting portion 221 and the second connecting portion 222 are connected by bolts. The first connecting portion 221 and the second connecting portion 222 are enclosed together to form a mounting hole 223. The shape of the mounting hole 223 is adapted to the seat support rod. The detachable connection between the first connecting portion 221 and the second connecting portion 222 facilitates the connection with the seat support rod. At the same time, when the two are connected by bolts, the size of the mounting hole 223 can be adjusted, so that it can adapt to the seat support rods of different models, and the adaptability is stronger.

[0028] In some embodiments, Figure 2 As shown, the rear end of the lateral swing member 21 is hinged to the front end of the connecting member 22, and the front end of the connecting member 22 is also provided with a locking member 23, which is used to lock the connecting member 22.

When connected, the frame connecting rod 42, the traction rod 1 and the front wheel mounting frame form a triangle, which is more stable and not prone to shaking during riding.

[0034] In some embodiments, Figure 5 and Figure 6 As shown, a ball joint 43 is provided on the frame clamping bracket 41, and a buckle 44 adapted to the ball joint 43 is provided at the end of the frame connecting rod 42, and the buckle 44 is clamped with the ball joint 43. When the frame connecting rod 42 is connected to the frame clamping bracket 41, the buckle 44 and the ball joint 43 can be directly clamped together, which is simpler and more convenient to operate.

[0035] In some embodiments, Figure 5 As shown, the frame clamping bracket 41 includes a first clamping portion 411 and a second clamping portion 412, which are detachably connected. The shape enclosed by the first clamping portion 411 and the second clamping portion 412 is compatible with the mounting vertical rod of the front wheel mounting frame, and the first clamping portion 411 and the second clamping portion 412 are sleeved on the periphery of the mounting vertical rod. By adopting the detachably connected first clamping portion 411 and the second clamping portion 412, it is more convenient to connect with the mounting vertical rod of the front wheel mounting frame, and the adaptability is stronger.

[0036] In some embodiments, Figure 6As shown, the frame connection assembly 4 also includes a fixing member 45, which is connected to the end of the frame connection rod 42 away from the buckle 44. The fixing member 45 is a collar and can be directly sleeved on the traction rod 1. The fixing member 45 can move along the extension direction of the traction rod 1 to change its position. When the position is determined, the fixing member 45 is locked and fixed to the traction rod 1. By connecting the fixing member 45 to the frame connection rod 42, the position of the frame connection rod 42 can be adjusted, which is convenient for connection with the frame clamping bracket 41.
