Summary of the invention
Technical problem to be solved by this invention is the height adjustment mechanism of the push rod providing a kind of structure simple, easy to adjust for the above-mentioned state of the art, by adjusting the height of push rod to the adjustment of push rod angle, and within the scope of adjusting angle, realize the angular adjustment without gear restriction.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of height adjustment mechanism of push rod, comprise the housing of machine, push rod, it is characterized in that: above the sidepiece of described housing, be provided with a rotating hole, 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 housing sidepiece by rotating shaft cover rotationally with coordinating of rotating hole; A support is provided with below the sidepiece of described housing, support laterally offers a mounting hole, mounting hole is provided with slidably a square neck screw, the lower end of the kink of described push rod is provided with through hole, described square neck screw is connected and fixed through through hole and a knob of mounting hole, push rod lower end, and realizing push rod centered by rotating shaft is overlapped, with mounting hole by the adjustment of knob is adjustment and the locking that track carries out angle.
As improvement, a mount pad is provided with above the sidepiece of described housing, described rotating hole is opened in the center of mount pad, arc groove is had in the both sides of rotating hole, described rotating shaft cover is placed on mount pad, the rotating shaft that rotating shaft puts is inserted in rotating hole, is provided with the circular arc boss coordinated with arc groove at the tail end of rotating shaft.
As improvement, described rotating shaft puts and has screw along rotating shaft, the outer face of rotating shaft cover forms the groove with the semicircle of push rod lateral engagement, and the kink upper end of described push rod is embedded in the groove of rotating shaft cover, and by screw through push rod upper through hole, be screwed into rotating shaft cover screw in fixing.
Improve, be provided with the Connection Block for mounting bracket below the sidepiece of described housing, Connection Block is provided with some joint pins again, described bracket cross section takes the shape of the letter U, and is provided with corresponding installation counterbore, by screw through installing counterbore, 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 described square neck screw is connected with knob through the through hole of mounting hole and push rod, is locked by push rod with coordinating of knob by square neck screw.
Finally, described machine adopts trimmer or mower.
Compared with prior art, the invention has the advantages that: rotating hole is set on housing, there is the U-shaped support of mounting hole, push rod is made to can be rotatably set on housing by rotary sleeve, with coordinating of knob, push rod adjustable ground is locked by square neck screw, wherein keyed end is positioned at the below of the point of rotation, and have the distance of a section longer, make only to need less power just push rod can be locked, the adjustment of push rod angle is realized by the slip of push rod lower end edge mounting hole, and then the height of regulating pushing rod.Structure of the present invention is simple, without the need to increasing the accessories such as telescoping tube, only need just can the height of quick adjustment push rod by the adjustment of angle, and easy accessibility, uses solid and reliable simultaneously, realizes the unspecified angle adjustment limited without gear within the scope of adjusting angle.

Fig. 2 is the scheme of installation that rotating hole of the present invention and rotating shaft are overlapped;
Fig. 3 is perspective view of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in the figure, a kind of height adjustment mechanism of push rod, comprise the housing 1 of machine, push rod 2, rotary sleeve 3 and knob 5, described push rod 2 is the bend pipe structure of approximate " L " shape, one end bending of push rod 2 forms the kink be connected with housing 1 afterwards, a mount pad 11 is provided with above the sidepiece of described housing 1, the center of mount pad 11 offers a rotating hole 12, the both sides of rotating hole 12 have arc groove 121, described rotating shaft cover 3 is provided with the rotating shaft 31 coordinated with rotating hole 12, rotating shaft 31 has screw, the afterbody of rotating shaft 31 is provided with the vertical slot 35 being convenient to elastic deformation, the tail end of rotating shaft 31 is provided with the circular arc boss 34 coordinated with arc groove 121, the outer surface of rotating shaft cover 3 forms the groove 32 with the semicircle of push rod 2 lateral engagement, described rotating shaft cover 3 is nested with on mount pad 11, housing 1 sidepiece is arranged on rotationally with coordinating of rotating hole 12 by rotating shaft 31, be embedded in the kink upper end of push rod 2 by the outside groove 32 of rotating shaft cover 3 simultaneously, and by the upper through hole 22 of screw 7 through push rod 2, be screwed in the screw of rotating shaft cover 3, push rod 2 and rotating shaft are overlapped 3 be connected and fixed, and due to coordinating of circular arc boss 34 and arc groove 121, buckle is formed after making rotation one low-angle, guarantee that rotating shaft cover 3 can not come off from housing 1, realize the firm stable of rotating shaft cover and rotating hole connection,
Connection Block 13 is provided with below the sidepiece of described housing 1, Connection Block 13 is provided with some joint pins 14, one cross section is that the support 4 of U-shaped is provided with corresponding installation counterbore 42, by screw 8 through installing counterbore 42, be screwed in joint pin 14, support 4 is fixed on housing 1, support 4 laterally offers the mounting hole 41 of an one end open, mounting hole 41 is provided with slidably a square neck screw 6, the lower end of the kink of described push rod 2 is shaped to flat cambered surface, cambered surface is provided with through hole 21, described square neck screw 6 is through mounting hole 41, the through hole 21 of push rod 2 lower end and a knob 5 are connected and fixed, push rod 2 is realized centered by rotating shaft cover 3 by the adjustment of knob 5, with mounting hole 41 for track carries out adjustment and the locking of angle.
When needing regulating pushing rod 2 height, as long as unscrew knob 5, make push rod 2 along with rotating shaft cover 3 turn to certain angle after knob 5 tightened lock, because push rod 2 is designed to the bend pipe structure of " L " shape, so along with the adjustment of angle, the height of push rod 2, also in change, therefore only needs adjusting angle just can realize adjustment highly, very convenient, and the unspecified angle that can realize within the scope of adjusting angle without gear restriction regulates.The height adjustment mechanism of this push rod is adapted at the garden instrument such as trimmer or mower is applied.
