Abstract
The invention discloses a gardening cutting tool which comprises a machine head component, a frame component and a rotary component arranged between the machine head component and the frame component. The rotary component comprises a first end tooth element and a second end tooth element connected with the first end teeth element in a matching mode. The first end tooth element is fixedly arranged on the frame component, and the second end tooth element is fixedly arranged on the machine head component. When and only when the frame component rotates relative to the machine head component can the first end teeth element and the second end tooth element mutually separate from each other. When the frame component is fixed relative to the machine head component, the first end tooth element is meshed with the second end tooth element. And therefore the gardening cutting tool can achieve angle adjustment of the machine head component and the frame component conveniently and simply, and is simple and reliable in structure.

Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is done further nonrestrictive detailed description.
Seeing figures.1.and.2, is a kind of grass mower or pruning machine corresponding to the gardening cutting tool of preferred embodiment of the present invention, and it is used for the lawn is placed under repair.This gardening cutting tool comprises nose assembly 1, chassis assembly 5 and is arranged on rotary components 7 between described nose assembly 1 and described chassis assembly 5.
Above-mentioned nose assembly 1 is provided with housing 11 and removably matched with described housing 11 holder 18.The blade assembly 14 and the first switch 16 that are provided with motor 10, driving wheel 12 in described housing 11, are driven by driving wheel.Described holder 18 is provided with elastic card buckle portion 13, described elastic card buckle portion 13 can with described housing 11 phase buckles.
The handle 53 that above-mentioned chassis assembly 5 is provided with a pair roller 50, is arranged on the push rod 52 between this pair roller 50 and is arranged on the end of push rod 52.The inside of this push rod 52 also is provided with bearing pin 54.The inside of handle 53 arranges second switch 55.
With further reference to Fig. 3 and Fig. 4, above-mentioned rotary components 7 comprises the first end tooth spare 72, the second end tooth spare 74 and flexible member 76 that can be matched with described the first end tooth spare 72.Above-mentioned the first end tooth spare 72 is fixedly installed to described chassis assembly 5, and corresponding to preferred embodiment of the present invention, this first end tooth spare 72 is fixedly connected by the push rod 52 of screw 78 with described chassis assembly 5.Above-mentioned the second toothed elements 74 is fixedly installed to the holder 18 of described nose assembly 1 by screw-threaded engagement, and on the push rod 52 of this second toothed elements 74 holder 18 of being set in simultaneously described nose assembly 1 and described chassis assembly 5.In addition, described first, second end tooth spare 72,74 be respectively equipped with can be intermeshing end tooth section 71,73, described end tooth section 71 and 73 has respectively slope 75,77, when producing like this rotation relatively between first, second end tooth spare 72,74, this slope 75,77 first, second the end tooth spare 72,74 that is arranged so that are easy to just can mutually slip over and cause mutual disengagement.Above-mentioned flexible member 76 is spring, and it is arranged between described nose assembly 1 and described chassis assembly 5.Particularly, this flexible member 76 is set on the bearing pin 54 of described chassis assembly 5, and one end (for label) is resisted against on the holder 18 of described nose assembly 1, and its other end is resisted against on the push rod 52 of described chassis assembly 5.
Like this, when grass mower of the present invention or pruning machine in the corner that cuts the grass on a lawn or during other specific positions and when needing to adjust the cutting angle of nose assembly 1, only need nose assembly 1 is carried out clockwise or is rotated counterclockwise with respect to chassis assembly 5, this moment, flexible member 76 was because of stressed compression, thereby was convenient to first, second end tooth spare 72,74 mutual disengagement; When nose assembly 1 rotates extremely suitable position, discharge, this moment, flexible member 76 can apply an elastic-restoring force in chassis assembly 5, thereby make first, second end tooth spare 72,74 return to again engagement, make to interfix motionlessly between nose assembly 1 and chassis assembly 5, keep the needed adjustment angle of user.As seen, grass mower of the present invention or pruning machine, its rotary components that provides 7 can be realized relative spinning movement between nose assembly 1 and chassis assembly 5 by a step rotary manipulation, so simple, convenient; And this rotary components 7 is relatively simple for structure, reliable.
In addition, described gardening cutting tool also comprises the switch changer-over device 19 that is arranged between described nose assembly 1 and described chassis assembly 5.This switch changer-over device 19 be provided with plug 21, with matched socket 23 and the feeler lever 25 of plug 21.This switching device 19 optionally is electrically connected mutually with the first switch 16 or second switch 55; Particularly, when described nose assembly 1 connected mutually with described chassis assembly 5, described switch changer-over device 19 can electrically separate mutually and electrically conduct mutually with described second switch 55 with described the first switch 16; When described nose assembly 1 was separated from each other with described chassis assembly 5, described switch changer-over device 19 can electrically conduct mutually and electrically separate mutually with described second switch 55 with described the first switch 16.Like this, the user directly just can control the Push And Release of machine on the handle 53 of chassis assembly 5, need not to walk to nose assembly 1 neighbouring to control the Push And Release of machine, has facilitated user's controlling machine.
It is pointed out that above-mentioned preferred embodiment only is explanation technical conceive of the present invention and characteristics, its purpose is to allow person skilled in the art scholar can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
