The middle parts of the first seat tube clamp 41 and the second seat tube clamp 42 are enclosed to form a circular through hole. When the seat tube 7 needs to be connected, the nuts sleeved by the bolts at the bottom of the first cam clamping rod 44 are removed. The first cam tightening rod 44 is moved to make it rotate axially along the first seat tube clamp 441, and the bolt under the first cam tightening rod 44 moves upward and disengages from the second seat tube clamp 42. The first seat tube clamp 41 and the second seat tube clamp 42 are respectively rotated axially along the fixed axis 43, so that the other ends of the first seat tube clamp 41 and the second seat tube clamp 42 are separated from each other to form an opening, and the seat tube 7 is inserted between the first seat tube clamp 41 and the second seat tube clamp 42 through the opening. Then the first seat tube clamp 41 and the second seat tube clamp 42 are rotated axially along the fixed axis 43, so that the other ends of the first seat tube clamp 41 and the second seat tube clamp 42 are close to each other, and the first cam tightening rod 44 is moved to make it rotate axially along the first seat tube clamp 441 to the initial position, and the bolt under the first cam tightening rod 44 moves downward and enters the second seat tube clamp 42, and is fixed by a nut.

[0030] like Figure 7 As shown, the support rod adjustment member 5 includes an adjustment clamp 51 and a second cam clamping rod 52. The adjustment clamp 51 is sleeved on the sleeve 11. A fixing bolt 51a is provided at the bottom of the adjustment clamp 51. The fixing bolt 51a abuts against the bottom of the sleeve 11. The second cam clamping rod 52 is fixed to the adjustment clamp 51 and connected to the adjustment clamp 51 axis. The bolt at the bottom of the second cam clamping rod 52 passes through one end of the opening of the adjustment clamp 51. When the length of the support rod 1 needs to be adjusted, the second cam tightening rod 52 is moved to move it along the adjustment clamp 51. 1 is rotated axially, and the bolt under the second cam tightening rod 52 moves downward accordingly, and the opening at one end of the adjusting clamp 51 becomes larger, so that the extrusion force in the adjusting clamp 51 becomes smaller, and the adjusting clamp 51 no longer squeezes the sleeve 11, and the insertion depth of the insert tube 12 in the sleeve 11 can be adjusted. After adjusting to a suitable length, the second cam tightening rod 52 is moved to rotate along the axial direction of the adjusting clamp 51 to return to the initial position, and the bolt under the second cam tightening rod 52 moves upward accordingly, and the opening at one end of the adjusting clamp 51 becomes smaller, squeezing the sleeve 11, so that the insert tube 12 inside the sleeve 11 is fixed on the sleeve 11.

[0031] When in use, connect the head tube connector 3 to the head tube 6, then adjust the support rod adjusting member 5 so that the insert tube 12 can move along the length direction of the sleeve 11, and then connect the seat tube connector 4 to the seat tube 7, adjust the support rod adjusting member 5 to fix the insert tube 12 on the sleeve 11, adjust the angle of the rotating connection assembly 24, so that the connecting rod 81 below the child seat 8 passes through the rotating connection assembly 24 and remains horizontal, and the child seat 8 above the connecting rod 81 remains horizontal.
