As for the cleaning end and the holding end used by the user, the adjustment technology of the device has not yet been disclosed. Therefore, applying the existing adjustment technology will cause a greater adjustment burden on the user, and there is room for improvement. Summary of the Invention

[0005] The purpose of the present utility model is to provide a steering knuckle to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a steering knuckle, comprising a steering knuckle, wherein the steering knuckle is used for freely rotating the cleaning end and the holding end of the cleaning tool, and a cleaning channel connecting the cleaning end and the holding end is provided inside the steering knuckle.

[0007] As a further solution of the present invention: the steering knuckle includes a handlebar rotating end, a steering seat and a connecting end, one side of the steering seat is fixedly connected to the connecting end, and the other side of the steering seat is movably connected to the handlebar rotating end through a control card.

[0008] As a further solution of the present invention: the handlebar rotating end includes a handlebar tube, a pipe mouth and a rotating shaft hole 1, the steering seat includes a movable hole, a rotating shaft hole 2 and a coordination groove, the control card includes a rotating shaft, the handlebar tube is plugged into the interior of the handlebar, a water pipe is embedded in the interior of the handlebar, one end of the water pipe passes through the pipe mouth and the steering seat and is led out to the connecting end away from the steering seat, and the rotating shaft hole 2 and the rotating shaft hole 1 are both adapted to the rotating shaft.

[0009] As a further solution of the present invention: a ratchet is fixedly mounted on the outer periphery of the rotating shaft, and a stop head is hingedly connected to the interior of the coordination groove through a hinge, and the stop head is adapted to the ratchet.

[0010] As a further solution of the present invention: a hoop is fixedly connected to one side of the connecting end, one end of the water pipe passes through the hoop and extends to one side of the hoop, and a pipe hoop sleeve is screwed on the outer periphery of the hoop.

[0011] As a further solution of the present invention: one end of the rotating shaft is fixedly connected to a mounting cap, and the outer periphery of the mounting cap is provided with anti-slip grooves.

[0012] As a further solution of the present invention: a shift rod is fixedly installed on the periphery of the hinge, a spring seat is fixedly connected to the side wall of the coordination groove, and the shift rod is adapted to the spring seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Since the rod barrel in the handlebar swivel end is used to connect the gripping end of the cleaning tool, and the connecting end is connected to the cleaning tool through the hoop, during use, the operator can use the steering seat as the basis to make the cleaning tool contact the ground, and the handlebar swivel end can be rotated 0-90 degrees to the left and right, so that the operator can hold and use the cleaning tool to clean the floor in a more comfortable way;

[0015] 2. Since one end of the water pipe passes through the pipe mouth and the steering seat and is led out to the end of the connection end away from the steering seat, specifically, one end of the water pipe passes through the hoop mouth and extends to one side of the hoop mouth, and the hoop mouth is directly connected to the cleaning tool, the water supplied by the water pipe to the cleaning tool will be output through a water outlet on the side of the cleaning tool. When the cleaning tool is cleaning, the water in the water outlet hole can be used to achieve the effect of washing the floor.

[0016] 3. A water outlet rod is provided on one side of the water outlet to adjust the water volume and prevent the backflow of sewage. A small hole is provided inside the water outlet rod. When water is discharged from the cleaning utensil, it can be slowly discharged outward through the small hole to adjust the water volume. The small hole has the effect of preventing the backflow of sewage, thereby avoiding the problem of the cleaning utensil being dirty due to the storage of sewage.

[0017] 4. Since ratchets are distributed in a circular array on the outer periphery of the rotating shaft, and the ratchet is a structure with a certain curvature, it cooperates with the stop head to allow the rotating shaft to rotate in one direction under certain circumstances, and the rotation relative to the rotation direction will have a self-locking function - that is, it can only rotate forward and not reverse. Therefore, during use, the person can use the hinge to rotate the stop head to the active area of ​​the ratchet. In the process of rotating the handlebar end and the steering seat, the stop head and the ratchet are specifically used to allow the rotating shaft to rotate in only one direction. Therefore, for the user, it can prevent you from causing the handlebar end and the steering seat to slide due to force deviation, which is convenient for the user to use.

[0018] 5. If the user needs to reset the handlebar end and the steering seat, the user can similarly rotate the stop head out of the range of motion of the ratchet wheel through the action of the hinge to achieve the purpose of resetting or free movement of the handlebar end and the steering seat.

[0019] 6. The pipe clamp sleeve can protect the clamp mouth when the steering knuckle is not connected to the cleaning tool, preventing the clamp mouth from being damaged.

[0020] 7. In order to prevent the lever from being accidentally touched, the present application fixes a spring seat on one side of the coordination slot so that the lever can be stored in the spring seat, thereby avoiding the problem of the stop rod being accidentally embedded in the ratchet activity area.
