Abstract
The invention discloses an improved structure of a locking device between a stand pipe and an adjusting pipe. The stand pipe is inserted in the adjusting pipe freely, and relative positions of the stand pipe and the adjusting pipe are fixed through a locking mechanism. The improved structure comprises a sliding block, wherein a sliding pipe in which the sliding block moves freely is arranged on the adjusting pipe, the sliding block can move freely inside the sliding pipe along the axial direction, an opening of the sliding pipe is formed in the stand pipe, and the sliding block can just abut against and loosen the stand pipe. The sliding block is composed of a front pressing block and a rear pressing block, the front pressing block is movably clamped between the stand pipe and the rear pressing block, the front pressing block can abut against and loosen the stand pipe under the action of the rear pressing block, and the distance between the front pressing block and the rear pressing block can be located and adjusted. When the fixing of the stand pipe by the front pressing block is affected due to abrasion of the front pressing block after long-term usage, first and second screws are screwed towards the stand pipe direction, and the front pressing block is pushed to advance towards the stand pipe direction; if the abrasion of the front pressing block is serious, only the front pressing block is required to be replaced. By the aid of the structure, the phenomenon that an end face of the sliding block is not matched with the stand pipe after the long-term usage of the sliding block can be avoided, and the structure is easy to use and operate.
