[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A kind of adjustable column head pull rod comprises a round tube 1, both ends of the round tube 1 are fixed with end caps 2, an inner nut 3 is fixed on the side of the end cap 2 close to the round tube 1, the inner nut 3 is located inside the round tube 1, both ends of the round tube 1 are provided with connectors 4, a threaded column 5 is fixed on the end of the connector 4 close to the round tube 1, the threads of the two threaded columns 5 are opposite, the threaded column 5 passes through the end cap 2 on the same side and is threadedly connected to the inner nut 3, an outer nut 6 is threadedly connected to the threaded column 5, and the outer nut 6 is located between the end cap 2 and the connector 4.

[0021] When the column head pull rod is in use, the connectors 4 at both ends are fixed to prevent rotation, and the round tube 1 is rotated. Since the threads of the two threaded columns 5 are opposite, the inner nut 3 is fixed to the round tube 1, and the inner nut 3 is threadedly connected to the threaded column 5, thereby enabling the connectors 4 at both ends to move to both sides and the column head pull rod to be extended. When it moves to the specified position, the outer nut 6 is rotated and moves along the threaded column 5 toward the end 2 until it contacts the end 2, thereby fixing the threaded column 5 so that it no longer rotates relative to the inner nut 3, thereby preventing the round tube 1 and the connector 4 from loosening.

[0022] In order to achieve angle adjustment of the column head pull rod, in this embodiment, the connecting head 4 is configured to realize a hinged structure.

[0023] In order to prevent the outer nut 6 and the end head 2 from loosening, in this embodiment, a gasket 7 is sleeved on the threaded column 5 , and the gasket 7 is located between the outer nut 6 and the end head 2 .

[0024] It is found in actual use that slipping may occur when the round tube 1 is rotated. In order to avoid the above problem, in this embodiment, the outer surface of the round tube 1 is provided with anti-slip grooves.

[0025] In order to increase the fixing strength of the structure, in this embodiment, the inner nut 3 and the end head 2 are fixed by welding.
