A winding device is provided at the end of the rotating rod, and a steel wire rope is provided at the output end of the winding device. A rotating sleeve is provided at the end of the steel wire rope. A limiting shaft is provided on the inner side of the rotating sleeve, and a limiting ring is installed on the inner side of the limiting shaft. Two sets of flip sleeves are installed on the front side of the limiting ring, and a fixing sleeve is provided on the inner side of the flip sleeve. A right-angle plate is installed on the front side of the fixing sleeve, and the right-angle plate is located on the back of the support platform.
[0007] The adjustment component includes a movable frame located inside the limiting ring. An adjustment groove is provided inside the movable frame, and an adjustment slider is provided inside the adjustment groove. A grouting head is provided inside the adjustment slider, and an auxiliary handle is installed on the top of the grouting head. A support spring is provided at the bottom of the auxiliary handle, and a movable ring is installed at the bottom of the support spring. The movable ring is located at the top of the adjustment slider.
[0008] Preferably, the bottom of the support platform is equipped with four sets of universal wheels, and the top of the support platform is equipped with a mixing tank. The top of the mixing tank is equipped with a feed inlet and a mixing motor. The output end of the mixing motor is equipped with a mixing blade, which is located inside the mixing tank. Guide wheels are provided on both sides of the upper end of the mixing tank, and the guide wheels are located outside the wire rope.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] First, this utility model, by installing an adjustment component, uses a limiting ring to restrict the inner movable frame. The movable frame can rotate along the limiting slide groove on the inner side using a limiting slide plate. Rotation can adjust the movement path of the inner adjustment groove of the movable frame. The adjusting slider can move along the inner side to adjust the position of the grouting head inserted into the inner side. By gripping the auxiliary handle, the grouting head can be pushed into the inner side of the combination groove. After insertion, it can be rotated 90 degrees as needed to maintain the combination between the threaded grooves, thereby achieving the restriction effect. The position of the grouting port can be flexibly adjusted using the adjustment component, which is convenient for adjustment and use according to needs.
[0016] Secondly, this utility model incorporates an auxiliary folding component. Since the adjustment component, when fixed to the back, occupies significant space and hinders normal transport, a winding motor drives the rotating rod to rotate. This rotation controls the winch inside the winding unit, which in turn controls the rotating sleeve and limiting shaft at the end of the wire rope. During the pulling process, the flipping sleeve flips along the combined shaft, maintaining a perpendicular position to the ground, thus reducing space requirements. Before folding, the grouting structure needs to be removed. The auxiliary folding component allows for flexible adjustment of the limiting ring's position, further reducing space and facilitating transport. Attached Figure Description
