[0007] The adjustment assembly has its bottom connected to the seat or cover via a connecting part. The adjustment assembly includes a longitudinal adjustment plate with a longitudinally arranged guide groove. The lower end of the armrest is slidably connected in the guide groove and is provided with a first locking member to lock its position in the guide groove. The upper end of the armrest is hinged to a fixed support and is provided with a second locking member to lock the relative angle between the two. The armrest is mounted on the fixed support.

[0008] Preferably, the lower end of the armrest is provided with a guide rail roller, which is located in the guide groove and rolls and guides the guide groove up and down; the guide groove is provided with a guide rail limiting block to restrict the movement height of the roller.

[0009] Preferably, the first locking member includes a first locking handle and a first bushing. The first locking handle and the first bushing are fitted together and installed in the lower hole of the armrest. When the first locking member is locked, the armrest is pressed against the longitudinal adjustment part.

[0010] Preferably, the upper end of the armrest is provided with a first connecting hole and a first waist-shaped hole arranged radially on the first connecting hole. The fixed support is rotated around the first connecting hole, and the lower end of the fixed support is connected to the first waist-shaped hole.

[0021] like Figure 1 As shown, this embodiment provides an adjustable handrail for a forklift, including: a handrail portion disposed on one side of the forklift seat; an operating portion disposed on the front side of the handrail portion, on which an operating component is provided; an adjusting component, the bottom of which is connected to the seat or machine cover via a connecting portion, the adjusting component including a longitudinal adjusting plate, on which a longitudinally arranged guide groove 21 is provided; the lower end of the handrail arm 26 is slidably connected in the guide groove 21, and a first locking member is provided to lock its position in the guide groove 21; the upper end of the handrail arm 26 is hinged to a fixed support 213, and a second locking member is provided to lock the relative angle between the two; the handrail portion is mounted on the fixed support 213.

[0022] As described above, one end of the armrest 26 can move up and down along the guide groove 21, and the fixed support 213 connected to the armrest can rotate back and forth relative to the armrest wall, thereby enabling the armrest to move up and down and back and forth to adjust, thus adapting to different drivers' operating postures or habits, conforming to ergonomic design, and improving the driving experience.

[0023] Combination Figure 2 In this embodiment, the lower end of the handrail 26 is provided with a guide roller 23, which is located in the guide groove 21 and rolls vertically with the guide groove 21 for guidance. A guide rail limiting block 24 is provided in the guide groove 21 to limit the height of the roller movement. The guide roller 23 makes the adjustment of the handrail 26 along the guide groove 21 more stable. In one embodiment, the diameter of the guide roller 23 is approximately equal to the width of the guide groove 21. In another embodiment, at least two guide rollers 23 are arranged vertically side-by-side. With this arrangement, it is not necessary for the diameters of the guide rollers 23 to be approximately equal to achieve the guiding engagement with the guide groove 21. The first locking member includes a first locking handle and a first bushing. The first locking handle and the first bushing are fitted into the lower hole of the handrail 26. In the locked state, the handrail 26 is pressed against the longitudinal adjustment part.
