Description

Technical Field

[0001] The utility model relates to the technical field of steering handlebar limiting, in particular to a steering handlebar limiting device for a walking tractor. Background Art

[0002] A walking tractor is a small tractor, and the steering of the walking tractor is achieved by clutch steering by pinching the handle on the handle, and the steering angle is adjusted according to the amplitude of the handle force rotation. This leads to the tractor oversteering and tipping over due to unskilled or accidental force on the handle during operation. For this reason, we propose a walking tractor steering handle limit device to solve the above problem.

[0003] In the Chinese utility model patent application disclosure specification CN214084420U, a steering handle limit device for a walking tractor is disclosed, comprising a fixed seat, a sleeve hole is provided on the fixed seat, and a clamping mechanism is installed in the sleeve hole, a slide groove is vertically provided at the left end of the fixed seat, and a useful second rod is vertically installed in the slide groove through a bearing, the upper end of the second screw rod passes through the fixed seat and is placed outside, the upper end of the second screw rod is fixedly welded with a second turning handle, a second nut is sleeved on the second screw rod, and a slider is fixedly sleeved on the second nut, and an L-shaped plate is fixedly welded on the slider. The utility model is installed on the handle of the tractor through the clamping mechanism, and the installation and disassembly are simple, and the position of the L-shaped plate can be adjusted by rotating the second turning handle, so as to limit the upper side of the steering handle through the L-shaped plate, so that the space for the handle to move is limited, thereby preventing the handle from being accidentally pinched too much and causing oversteering, but the adjustment ability of the device is slightly insufficient, not convenient, and the device cannot install handles of different diameters, and the flexibility is poor. For this reason, we propose a steering handle limit device for a walking tractor. Utility Model Content
