The top of the front support column 22 is fixedly connected with the arc block 25, which is fixed to the top of the front support column 22 and contacts the outer part of the top connecting rod 23. The arc block 25 limits or guides the movement range of the connecting rod 23, ensuring that the connecting rod 23 remains in the predetermined track during rotation, preventing it from swinging excessively or deviating from the normal position, thereby ensuring the contact pressure and relative position between the roller 24 and the hose 21, maintaining the accuracy and reliability of the hose 21 winding and unwinding action.
