The technical solution of the utility model is as follows: a kind of handrails of micro-cultivator left and right adjusting device, comprise arm-rest frame (1), guard shield (2) and armrest seat (3), the crosspiece of described arm-rest frame (1) front end is connected with guard shield (2), guard shield (2) is fixedly installed on the tail end of armrest seat (3), its key is: locating dowel (4) is inserted in the bottom of described armrest seat (3) front end, both matched in clearance, locating dowel (4) is vertically fixed on the top board (5a) of vertical tube socket (5), and on top board (5a), have a plurality of by the locating holes (5b) of even circumferential distribution, the place ahead at described armrest seat (3) front end arranges positioning pipe (6), the lower end of lifting arm (7) is stretched in positioning pipe (6), and be connected with the upper end of telescopic head (8), insert in one of them locating hole (5b) lower end of described telescopic head (8), on described lifting arm (7), be arranged with stage clip (9), the end face butt of the lower end of this stage clip (9) and telescopic head (8), the fixing catch (10) in the upper end of stage clip (9) and positioning pipe (6) top connects.
Adopt above technical scheme, telescopic head inserts in one of them locating hole, and armrest seat is positioned, and stage clip makes the top board of telescopic head and vertical tube socket peg graft closely under the effect of its elastic force, to prevent that armrest seat from shaking.When position, needs adjustable handrail left and right, first, carry lifting arm, make lifting arm drive telescopic head to leave corresponding locating hole, follow rotary handle frame to the left or to the right, arm-rest frame is turned an angle around locating dowel together with armrest seat, armrest seat drives positioning pipe, lifting arm and telescopic head to rotate together, make telescopic head turn to the position of another locating hole on corresponding top board, finally unclamp lifting arm, under the effect of stage clip screen resilience, lifting arm and telescopic head are descending, and telescopic head inserts in new locating hole, again complete the location after the position adjustments of armrest seat left and right.As can be seen here, the utility model is simple in structure, easy to assembly, and production cost is low, and position adjustments operation in left and right is not only convenient but also quick on the one hand; On the other hand, the scope of left and right position adjustments is larger, and the good reliability regulating.
At the rear side fixing and locking clamp (11) of described armrest seat (3) front bottom end, on this locking clamp (11), be formed with Ka Tai, described card decometer enters in the annular groove of offering in locating dowel (4).Above structure, when not affecting the rotation of armrest seat relative positioning post, can prevent that armrest seat from upper and lower play occurring.
The lower end of described lifting arm (7) and telescopic head (8) threaded engagement, both easy accessibility like this, it is firm to connect; Upper end at lifting arm (7) is provided with drop handle, so that control lifting arm.
Easier in order to make telescopic head insert locating hole, on described top board (5a), have 10 locating holes (5b), this locating hole (5b) is kidney-shaped.
Beneficial effect: the utility model is the position, left and right of adjustable handrail as required, and not only adjustable range is larger, and operation is not only convenient but also reliable, has the features such as design is ingenious, simple in structure, transformation is easy, improvement cost is low.
