Description
Technical field
The present invention relates to a kind of mower, particularly relate to a kind of mower with dismountable guard shield.
Background technology
In prior art, in order to prevent the mower foreign material such as grass bits splashing in use, the working head of mower all can install guard shield, by guard shield, foreign material are directed to the side deviating from user, foreign material are thrown away user by the centrifugal force produced by the rotation of working head, ensure that the safety of user; Owing to contacting with foreign material for a long time, guard shield needs periodic cleaning, therefore guard shield and working head need to be designed to dismountable annexation, will cause a problem like this: general guard shield is all connected with working head by the relation of being rigidly connected, this no matter how precision of being rigidly connected must be apertured, and working head has very strong rocking when beating the grass, this gap of long duration can be increasing, until guard shield loosens, causes potential safety hazard; A kind of technical scheme is had to be fastened on working head by screw by guard shield, but after working head work a period of time, screw still inevitably loosens, user is needed often to use other instruments to tighten screw, add the burden of user, user is also easy to forget and tightens, and also can produce certain potential safety hazard.
Summary of the invention
The object of this invention is to provide a kind of mower, this mower can make guard shield produce hardly when working head is beaten the grass to rock, significantly reduce potential safety hazard.
In order to overcome the defect of prior art, the invention provides a kind of mower, the guard shield comprising fuselage, be fixed on the working head with function of beating the grass of described fuselage one end, be removably connected with described working head, described working head is provided with connector, described guard shield is provided with the link slot that can match with described connector, described connector is removably plugged in described link slot, and the sidewall of described link slot is provided with the elastic component that described connector can be pressed in described link slot.
Preferably, described elastic component is arranged on the sidewall of described link slot both sides symmetrically.
Further preferably, described elastic component is metal clips, described guard shield offers the mounting groove be connected by interconnecting part with described link slot, described metal clips is fixed in described mounting groove by securing member, described metal clips has the bossing of the elastic-restoring force that can provide perpendicular to described link slot bearing of trend, described bossing is extended in described link slot by described interconnecting part.
Further preferably, described metal clips is L shape, and described bossing is the knuckle place of L shape.
Further preferably, described securing member is screw.
Connection between working head and guard shield to be become by elastic component and is flexible coupling by mower of the present invention, elastic component absorbs the position deviation that working head and guard shield operationally produce, enable each parts smooth working, guard shield can not depart from working head because loosening, and reduces potential safety hazard; This mounting means does not need additionally to use other instruments simultaneously, brings facility to user.

Embodiment
Be described in detail below in conjunction with the preferred embodiment of accompanying drawing to mower of the present invention.
See accompanying drawing 1-5, mower of the present invention comprises fuselage 1, and fuselage 1 is generally elongated rod shape, and its one end is provided with working head 2, working head 2 forms primarily of motor and element of beating the grass, guard shield 3 is removably connected with working head 2, specifically, working head 2 is provided with connector 21, guard shield 3 is provided with link slot 31, connector 21 can be plugged in link slot 31, and the sidewall of link slot 31 is provided with elastic component 32, and connector 21 can be pressed in link slot 31 by this elastic component 32.Specifically, guard shield 3 offers the mounting groove 34 that can hold elastic component 32, be communicated with by an interconnecting part between mounting groove 34 with link slot 31, elastic component 32 has bossing, and when elastic component 32 is housed in mounting groove 34, bossing extends in link slot 31 by above-mentioned interconnecting part, in the present embodiment, connector, by applying the power perpendicular to link slot 31 bearing of trend to connector 21, clamps by elastic component 32, realizes the connection of guard shield 3 and working head 2.
As a preferred version, elastic component 32 can be arranged in the bilateral symmetry of link slot 31, and such as left and right respectively arranges an identical connector 32, and making to be applied to, connector 21 is the contrary power in two equal and opposite in direction directions, the better effects if clamped like this; Simultaneously, elastic component 32 uses metal clips, such as with steel disc after bending, form L shape, the knuckle place of L shape is exactly above-mentioned bossing, and this bossing, by the interconnecting part between mounting groove 34 and link slot 31, extends in link slot 31, when connector 21 inserts in link slot 31, will contact with this bossing.
Can be fixed on better in mounting groove 34 to make elastic component 32, securing member 33 is used to be pressed in mounting groove 34 by elastic component 32 in the present embodiment, specifically, because elastic component 32 have employed metal clips, therefore securing member 33 have employed screw, can more sheathed pads on screw, like this when metal clips is housed in mounting groove 34, screw pushes down metal clips from top to bottom together with pad, like this, even if working head 2 operationally creates and rocks, because screw does not directly contact with working head 2, therefore can not produce loosening, such user does not need additionally to carry the instruments such as screwdriver in case loosened screw when using mower.
When mower works, working head 2 creates and rocks, but due to connector 21 and elastic component 32 close contact, the position deviation that working head 2 rocks generation is all absorbed by elastic component 32, therefore can not produce gap after working long hours, between working head 2 and guard shield 3, still be in close-connected state.
The present invention is compared to prior art, the position deviation produced because rocking between working head 2 and guard shield 3 is sponged by the elasticity of elastic component 32, make the anatomical connectivity of whole mower compact, guard shield 3 can not loosen for a long time because of service time, the mounting means of this connector-link slot is comparatively convenient simultaneously, user just can complete installation without any need for instrument, has both alleviated the burden of user, has also eliminated potential safety hazard.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
