Abstract

The invention relates to a position adjustable handle lever and an agricultural machinery steering handle. The position adjustable handle lever comprises a handle lever seaming, a limiting bracket, arotary support, a pull rod and a limiting pin, wherein the lower end of the handle lever seaming is hinged to the rotary support; the limiting bracket is fixed in the middle of the handle lever seaming; a guiding groove is formed in the limiting bracket; the pull rod is movably arranged on the limiting bracket; the pull rod and the handle lever seaming are arranged side by side; the limiting pin is arranged at the lower end of the pull rod, is in elastic connection onto the limiting bracket and is positioned in the guiding groove; a plurality of limiting grooves are sequentially formed in therotary support side by side; the limiting bracket is partially coincided with the rotary support, so that the guiding groove can be partially coincided with any of limiting grooves when the handle lever seaming rotates relative to the rotary support, wherein when the handle lever has position switching, the pull rod is pulled to move the limiting pin out of one limiting groove; the handle lever seaming is rotated to another position, so that the guiding groove is corresponding to another limiting groove, and the limiting pin is released and enters another limiting groove.

Description

technical field [0001] The invention relates to the related technical field of agricultural motor vehicles, in particular to a position-adjustable handle bar and an agricultural machinery steering handle. Background technique [0002] At present, the steering and lifting handles of the cab models of agricultural vehicles (such as crawler vehicles) on the market are located on the right console of the cab, and the angle of the joystick lever is fixed, which cannot meet the needs of different groups of people for the comfort of the joystick position. After the assembly of the control assembly is completed, the handle is bent beyond the console, and it is easy to touch it when the driver enters and exits the aisle of the cab, resulting in misoperation and potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is that the position of the handle bar on the console of the agricultural motor vehicle cab cannot be a...
