The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of height adjustment mechanism of push rod, the housing, the push rod that comprise machine, it is characterized in that: be provided with a rotating hole above the sidepiece of described housing, described push rod is bend pipe structure, the upper end of the kink of described push rod is provided with a rotating shaft cover, and described push rod is arranged on the housing sidepiece rotationally by rotating shaft cover and coordinating of rotating hole; Be provided with a support below the sidepiece of described housing, laterally offer a mounting hole on support, be provided with slidably a square neck screw on mounting hole, the lower end of the kink of described push rod is provided with through hole, through hole and a knob that described square neck screw passes mounting hole, push rod lower end are connected and fixed, the adjusting by knob realize push rod centered by the rotating shaft cover, carry out adjusting and the locking of angle take mounting hole as track.
As improvement, be provided with a mount pad above the sidepiece of described housing, described rotating hole is opened in the center of mount pad, both sides at rotating hole have arc groove, described rotating shaft cover is placed on mount pad, the rotating shaft that rotating shaft puts is inserted in rotating hole, is provided with at the tail end of rotating shaft the circular arc boss that coordinates with arc groove.
As improvement, described rotating shaft puts along rotating shaft and has screw, the outer face of rotating shaft cover forms the groove of the semicircle that coordinates with the push rod sidepiece, and the kink upper end of described push rod is embedded in the groove of rotating shaft cover, and by screw pass push rod upper through hole, be screwed in the screw of rotating shaft cover and fix.
Improve, be provided with the Connection Block for mounting bracket below the sidepiece of described housing, Connection Block is provided with some joint pins, described support cross section takes the shape of the letter U, and is provided with corresponding installation counterbore, passes the installation counterbore by screw, be screwed in joint pin, support is fixed on housing.
The lower end of the kink of described push rod is compressed to flat, and the through hole that described square neck screw passes mounting hole and push rod is connected with knob, by square neck screw and coordinating of knob push rod being locked.
At last, described machine adopts trimmer or mower.
Compared with prior art, the invention has the advantages that: rotating hole is set on housing, has the U-shaped support of mounting hole, by rotary sleeve, push rod be can be rotatably set on housing, by making square neck screw and coordinating of knob the locking of push rod adjustable ground, wherein keyed end is positioned at the below of the point of rotation, and one section long distance is arranged, making only needs less power just push rod can be locked, realize the adjusting of push rod angle by the slip of push rod lower end edge mounting hole, and then the height of regulating pushing rod.The present invention is simple in structure, need not to increase the accessories such as telescoping tube, but only needs the adjusting height of quick adjustment push rod just by angle, and easy accessibility simultaneously uses solid and reliablely, realizes the unspecified angle adjusting without the gear restriction in the adjusting angle scope.
