When the support seat moves later, the adjusting wheel can push the transmission belt to move, so that it maintains the tension effect and ensures the normal transmission of power.

[0036] (4) The rotation of the hose reel can be limited by the connection between the limit block and the synchronization shaft to keep it stable, and the connection between the limit block and the synchronization shaft can be controlled by the movement of the support seat. The forward movement of the support seat can automatically release the connection between the limit block and the synchronization shaft, so that the hose reel can rotate. The unwinding of the hose body can be controlled by directly pulling the hose body. It can be operated by one person to achieve automatic unwinding.

[0037] (5) The connection block can drive the limit block to move by squeezing the connection groove through the fixed block, thereby releasing the connection between the limit block and the synchronous shaft. After the tube body is released, the support seat can be moved backward and reset under the action of the second reset spring, and the limit block continues to limit the synchronous shaft, thereby realizing automatic locking of the tube body.
