Therefore, as the locking seat 40 is fixed relative to the fixed pipe 10 and the locking head 41 is not axially rotatable relative to the telescopic pipe 11, after the locking seat 40 and the locking head 41 are mutually inserted and locked, the fixed pipe 10 and the telescopic pipe 11 cannot circumferentially rotate, and the risk that the horizontal bar main body 102 is loosened and falls in the use process is avoided.

As shown in fig. 1 and 2, the lower side of the locking head 41 is provided with a connecting seat 42, and the second end 103b of the supporting rod 103 is connected to the connecting seat 42 through a shaft pin X, so that the supporting rod 103 and the horizontal bar body 102 can rotate. The first end 103a of the support rod 103 is hinged to the nut 31, so that the nut 31 and the support rod 103 can rotate. Furthermore, the two rotatable connections are mutually matched and linked, so that when the screw rod 30 is rotated to enable the nut 31 at the first end 103a of the supporting rod 103 to move up and down on the screw rod 30, the supporting angle of the supporting rod 103 can be synchronously and continuously changed.

However, considering that the telescopic horizontal bar may be fixedly installed under various usage scenarios, when the distance between two opposite vertical support walls is excessively small or large, there is a possibility of exceeding the adjustment range of the screw rod. In order to break through the limitations of different installation conditions and meet the requirements of consumers to the greatest extent, the sectional type length adjusting structure formed by splicing the first support rod 1 and the second support rod 2 in the embodiment of the design cost of the support rod can adapt to installation conditions of more use scenes and reduce the manufacturing cost.

In addition, the structure of the other parts of the telescopic horizontal bar 200 utilizing the lead screw to lock the support rod provided by the embodiment is the same as that of the embodiment one, and the description is omitted here.
