[0008] An operating groove is provided inside one side of the mounting piece, and a positioning rod is inserted into the operating groove and the inside of the connecting piece. A limiting disk is fixed on the left side of the positioning rod, and a spring sleeve is sleeved on the positioning rod.

[0009] In a preferred embodiment, the lower mounting ring and the upper mounting ring are hinged at the rear, and the lower mounting ring and the upper mounting ring are mounted at the front by fastening bolts.

[0010] In a preferred embodiment, a positioning clip used in conjunction with the aluminum alloy handle is fixed on the left side of the support rod, and the positioning clip is adapted to the aluminum alloy handle.

[0011] In a preferred embodiment, a positioning hole is formed in the connection member at a position relative to the positioning rod, and the positioning rod is inserted into the positioning hole.

[0012] In a preferred embodiment, one end of the spring sleeve is fixedly connected to the inner side wall of the operating groove, and the other end of the spring sleeve is fixedly connected to the limit plate.

[0013] In a preferred embodiment, the outer diameter of the spring sleeve is larger than the inner diameter of the operating groove.

[0014] In a preferred embodiment, a pull ring is fixed to a side of the limiting plate away from the positioning rod.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: the aluminum alloy hand bar can be better supported and guided by the universal wheel, which saves manpower and increases work efficiency.

[0016] 1. In the utility model, the working head can be lifted and lowered for use by the cooperation of the aluminum alloy hand rod and the front handle.

[0017] 2. In the utility model, by inserting the positioning rod into the connecting piece, the support rod and the universal wheel can be placed vertically, so that the universal wheel can support and guide the aluminum alloy hand rod, saving manpower and increasing work efficiency.

[0018] 3. In the present invention, the support rod and the universal wheel can be flipped and adjusted by pulling the positioning rod out from the inside of the connecting piece. When the positioning clip is connected to the aluminum alloy hand rod, the universal wheel can be stored, which is convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS
