Fixing frame with telescopic function

The utility model relates to the technical field of fixing frames, and discloses a fixing frame with a telescopic function, which comprises an upper fixing frame, a lower fixing frame and a connecting bracket, the upper fixing frame comprises a fixed frame, a movable frame, a moving block, a screw rod, a transverse groove and a limiting piece. During use, the screw rod is rotated to be matched with the limiting piece, so that the moving block is driven to move in the transverse groove, and then the movable frame is made to move. By the adoption of the structure, compared with the prior art, the telescopic distance can be accurately adjusted, so that a water seal bottle is better fixed, and water seal bottle structures with different lengths are better matched; meanwhile, compared with the prior art, the structure is more stable; and the movable frame and the moving block are detachably connected and can be conveniently disassembled and assembled. 本实用新型涉及固定架技术领域，且公开了一种具有伸缩功能的固定架，包括结构相同的上固定架、下固定架和连接支架；所述上固定架包括固
