The embodiment of the utility model discloses long regulation structure of leg. Referring to fig. 1 and 2, adjust the structure and include inside hollow second connecting rod 2 and sliding connection first connecting rod 1 on second connecting rod 2, first connecting rod 1 cover is established on second connecting rod 2, and the one end that first connecting rod 1 was kept away from to second connecting rod 2 is fixed with the supporting seat, and the diameter of supporting seat is greater than the diameter of second connecting rod 2, conveniently adjusts the stable subaerial placing of structure. The first connecting rod 1 is provided with an eccentric pipe clamp 4, the eccentric pipe clamp 4 is provided with a locking bolt 42 for fixing the eccentric pipe clamp 4 on the first connecting rod 1, and the locking bolt 42 is used for fixedly installing the eccentric pipe clamp 4 on the lower end of the first connecting rod 1. For better fixation of the eccentric pipe clamp 4, in this embodiment, two locking bolts 42 are provided. An adjusting assembly 3 is arranged in the eccentric pipe clamp 4, and the adjusting assembly 3 is used for adjusting the length of the first connecting rod 1 in the second connecting rod 2.

Referring to fig. 2, the adjusting assembly 3 includes a snap 31 disposed in the second link 2, the snap 31 includes a spring sheet 311 and a protrusion 312 disposed on the spring sheet 311, in this embodiment, the spring sheet 311 is V-shaped, one end of the V-shaped spring sheet 311 is pressed into the eccentric pipe clamp 4, and the protrusion 312 is disposed at the other end of the V-shaped spring sheet 311. The second link 2 is provided with a yielding hole 21 for the protrusion 312 to extend out, and the protrusion 312 on the elastic sheet 311 extends out of the yielding hole 21 all the time when the elastic sheet 311 is in a natural state. A plurality of adjusting holes 11 are formed in the first connecting rod 1, the adjusting holes 11 are arranged along the axial direction of the first connecting rod 1 at equal intervals, and the worker installs the protrusions 312 to the corresponding positions of the adjusting holes 11 of the first connecting rod 1 according to the required length.

In order to prevent the first link 1 from rotating on the second link 2, referring to fig. 1 and 2, a limiting groove 22 is formed on the second link 2, the limiting groove 22 is formed along the length direction of the second link 2, and the limiting groove 22 is in a long strip shape. The eccentric pipe clamp 4 is further provided with a limiting bolt 41 in a penetrating mode, in order to enable the limiting bolt 41 to slide in the limiting groove 22, the first connecting rod 1 is provided with a jack 12, after the limiting bolt 41 penetrates through the eccentric pipe clamp 4 and the jack 12 in the first connecting rod 1, the limiting bolt 41 is connected in the limiting groove 22 in a sliding mode, and therefore the first connecting rod 1 and the second connecting rod 2 cannot rotate relatively.

Referring to fig. 2 and 3, a handle 43 is rotatably connected to the eccentric pipe clamp 4, the rotating axis of the handle 43 is different from the rotating axis of the eccentric pipe clamp 4, when a worker installs the eccentric pipe clamp 4 on the first connecting rod 1, the locking bolt 42 is tightened, then the worker rotates the handle 43, since the rotating axis of the handle 43 is different from the rotating axis of the eccentric pipe clamp 4, when the rotating handle 43 is close to the eccentric pipe clamp 4, the handle 43 acts to contract the eccentric pipe clamp 4, further contract the opening bush 5, increase friction force, and clamp the second connecting rod 2, the first connecting rod 1 and the second connecting rod 2 are relatively fixed, the friction force between the first connecting rod 1 and the second connecting rod 2 is increased, and the position is more stable.
