Two forks 19 are symmetrically provided on the left and right ends of the front side of the lifting slide 3 corresponding to the positions of the clamping plates 6, and the special-shaped limiting plates 7 are pushed to slide back and forth inside the inner cavity 11. In this way, the distance between the special-shaped limiting plate 7 and the lifting slide 3 is changed according to the width of the goods. After the goods are forked onto the forks 19, the motor 12 drives the screw rod 13 to rotate, and the screw rod 13 drives the pressing plate 6 to move downward through the driving plate 5 until the goods are pressed. When the goods are pressed, the special-shaped limiting plate 7 blocks the front side of the goods to ensure that the goods will not slide directly to the front of the forklift due to inertia, so as to solve the problem that common counterbalanced forklifts only include a clamping function for the goods, which can clamp the goods on the forks 19, but lack an adjustable limiting function, and cannot guarantee that its position can be limited according to the width of the goods. It is easy for the goods to slide directly to the front of the forklift due to inertia after being clamped on the forks 19, affecting the stability of cargo transportation.

When the position of the special-shaped limit plate 7 needs to be adjusted according to the width of the cargo, the bolts on the special-shaped limit plate 7 are first removed, and then the special-shaped limit plate 7 is pushed to slide back and forth inside the inner cavity 11, so as to change the distance between the special-shaped limit plate 7 and the lifting slide 3 according to the width of the cargo. After the position adjustment of the special-shaped limit plate 7 is completed, the bolt is passed through the adjustment hole 8 and then screwed into the inside of the fixing hole 9 to fix it to the clamping plate 6, realizing an adjustable limit function, preventing the cargo from sliding directly to the front of the forklift due to inertia after being compressed on the cargo fork 19, affecting the stability of cargo transportation.

[0026] When the goods are forked onto the fork 19, the motor 12 drives the screw rod 13 to rotate, and the screw rod 13 drives the pressing plate 6 to move downward through the driving plate 5 until the goods are pressed. When the position of the special-shaped limiting plate 7 needs to be adjusted according to the width of the goods, the bolts on the special-shaped limiting plate 7 are first removed, and then the special-shaped limiting plate 7 is pushed back and forth inside the inner cavity 11 to change the distance between the special-shaped limiting plate 7 and the lifting slide 3 according to the width of the goods. After the position adjustment of the special-shaped limiting plate 7 is completed, the bolt is passed through the adjusting hole 8 and then screwed into the inside of the fixing hole 9 to fix it with the pressing plate 6, realizing an adjustable limiting function.

[0027] Through the above steps, the special-shaped limiting plate 7 is pushed to slide back and forth inside the inner cavity 11, so as to change the distance between the special-shaped limiting plate 7 and the lifting slide 3 according to the width of the goods. After the goods are forked onto the fork 19, the motor 12 drives the screw rod 13 to rotate, and the screw rod 13 drives the pressing plate 6 to move downward through the driving plate 5 until the goods are pressed. When the goods are pressed, the special-shaped limiting plate 7 blocks the front side of the goods to ensure that the goods will not slide directly to the front of the forklift due to inertia, so as to solve the problem of common counterbalanced forklifts, which only include a clamping function for the goods and can clamp the goods on the fork 19, but lack an adjustable limiting function, and cannot guarantee that its position can be limited according to the width of the goods.
