[0017] Reference Figure 1 and Figure 2 A device for controlling an acceleration pedal of a counterbalanced forklift in a darkroom comprises a first adjusting arm 1, a supporting arm 3, a second adjusting arm 4 and a third adjusting arm 7. The supporting arm 3 is provided with a second adjusting arm 4 and a third adjusting arm 7 with adjustable lengths on both sides in a horizontal direction. The second adjusting arm 4 and the third adjusting arm 7 are used to be fixed inside the forklift. Figure 2As shown, the second adjusting arm 4 and the third adjusting arm 7 are fixed to the forklift support plate 1 5 and the forklift support plate 2 8 respectively. The forklift support plate 1 5 and the forklift support plate 2 8 can be the inner wall of the forklift, or can be the mounting brackets of various instruments inside the forklift. The support arm 3 is vertically mounted with a first adjusting arm 1 with adjustable length. The first adjusting arm 1 is used to press down the accelerator pedal 9 of the forklift to a specified position. The material of the first adjusting arm 1, the support arm 3, the second adjusting arm 4 and the third adjusting arm 7 is a non-metallic material that neither absorbs nor reflects electromagnetic waves and has a target strength. The non-metallic material is nylon or hard rubber.
