Detailed Embodiments

[0019] Refer to Figures 1-4, Adjustable fork carrier distance adjustment cylinder fixing structure, including a fork carrier 1, multiple distance adjustment cylinders 2 are sleeved inside the fork carrier 1, a fixed bottom plate 3 is fixed on the side wall of the upper cross beam of the fork carrier 1, multiple fixing structures 4 are arranged on the side wall of the fixed bottom plate 3, and each fixing structure 4 is respectively sleeved and fixed on the surface of the corresponding distance adjustment cylinder 2. Adjustable support plates 5 are arranged on the side wall of the fixed bottom plate 3 and on both sides of the multiple fixing structures 4. The fixed bottom plate 3 is firmly installed on the cross beam of the fork carrier 1 by welding. Two parallel and independent waist-shaped holes 6 are provided on the fixed bottom plate 3. The adjustable support plate 5 has dimensions corresponding to the waist-shaped holes 6 and can slide freely along the length direction of the waist-shaped holes 6 and be locked at any position by bolts. By adjusting the position of the adjustable support plate 5 in the waist-shaped holes 6, distance adjustment cylinders 2 of different diameters can be adapted. The fixed bottom plate 3 forms a lateral support for the adjustable support plate 5 to enhance stability;

[0020] The fixing structure 4 includes an annular metal band 41 and an adjusting bolt 42 threadedly installed on the side wall of the fixed bottom plate 3. A fixing bolt 43 is sleeved between the annular metal band 41 and the fixed bottom plate 3. One end of the adjusting bolt 42 extends into the inside of the annular metal band 41 and a metal plate 44 is fixed. A rubber pad 45 is sleeved on the surface of the metal plate 44.
