Detailed description of the invention
It is embodiment of the present invention brush cutter as shown in Figures 1 to 3, it includes work 1, mobile jib 2, handle 3, adjusting part 4 and Power Component 5, described work 1 and Power Component 5 lay respectively at mobile jib 2 two ends, and the power that Power Component produces makes work 1 work, thus cutting shrub. Mobile jib 2 is provided with handle 3, and handle 3 is arranged on mobile jib 2 by adjusting part 4. Handle 3 has use position and non-use position, it is preferred that use position to only have one in the present embodiment. When handle 3 is positioned at use position, handle 3 can be fixed on mobile jib 2 by adjusting part 4, and now handle 3 cannot rotate. When handle 3 is positioned at non-use position, handle 3 cannot be fixed by adjusting part 4. It is the central axis of mobile jib that described mobile jib 2 has mobile jib axis Y, mobile jib axis Y. Described handle 3 includes pipe portion 31 and operating portion 32, and operating portion 32 has two, lays respectively at both sides, pipe portion 31, the shape making handle 3 substantially becomes U-shaped, pipe portion 31 has pipe portion axis X, and pipe portion axis X is the central axis in pipe portion 31, and vertical axis Z is perpendicular to axis X and Y place plane. Adjusting part 4 makes handle fix by fixing pipe portion 31, grips and controls when operating portion 32 is for using machine to operator. When handle 2 is when operating position, mobile jib axis Y and pipe portion axis X oblique, form pincer attack A, included angle A range for 75 �� to 85 ��, more specifically, the present embodiment included angle A is 80 ��. In operator P(Fig. 1, circle represents operator) stand on the left of brush cutter, when operator's both hands hold operating portion 32, work 1 is positioned at the dead ahead of operator's sight line, and now handle 3 is parallel to operator's health, and will not keep off lower limb, meets human engineering. When operation adjusting part 4 release handle 3 fixing after, handle 3 can rotate around pipe portion axis X and vertical axis Z simultaneously, and handle 3 can be turned to non-use position, and at non-use position, handle 3 cannot be fixed by adjusting part 4. Described non-use position includes reception position, handle 3 is rotated to pipe portion axis X around vertical axis Z almost parallel with mobile jib axis Y, now the space shared by handle 3 is reduced by, further, being rotated around pipe portion axis X by handle 3, make operating portion towards mobile jib side (as shown in Figure 3), now handle 3 would not take the big quantity space above brush cutter, space, instant packed and storage are saved. Described handle 3 also can move along axis X direction, pipe portion, and therefore operator's adjustable handle is in the position of the mobile jib left and right sides, and namely handle 3 can move to operator's left hand or right-hand lay.
As in figure 2 it is shown, adjusting part 4 includes knob 41, Handleset and mobile jib assembly, Handleset includes handle upper cover 42, handle lower cover 43. Mobile jib assembly includes mobile jib upper cover 44 and mobile jib lower cover 45, during assembling, first mobile jib upper cover 44 and mobile jib lower cover 45 are fixed on mobile jib 2, then with handle upper cover 42 and handle lower cover 43, handle 3 is fixed, connect with mobile jib upper cover, together with now Handleset connects with mobile jib assembly, insert knob 41 after then adjusting angle and fix.Knob 41 includes screw rod 411, and knob is screwed by screw rod and threaded engagement. Shown vertical axis Z is the central axis of screw rod. Described adjusting part 4 also includes the first spring 46 and the second spring 47, first spring 46 is arranged between handle upper cover 4 and handle lower cover 43, after unscrewing knob 41, handle upper cover is separated with handle lower cover by the first spring by elastic force so that handle 3 can rotate around pipe portion axis X. Second spring is arranged between handle lower cover 43 and mobile jib upper cover 44, and after unscrewing knob 41, handle lower cover 43 and mobile jib upper cover 44 are separated by the second spring so that Handleset and mobile jib assembly can relatively rotate, and therefore handle 3 can rotate around vertical axis Z. Fixed by teeth portion 441 and the slot fit being arranged on handle lower cover 43 between Handleset and mobile jib assembly. The adjusting part 4 of the present invention is operated by knob 41 i.e. fixed handle or releases fixing, it is not necessary to other instruments, also without pulling down handle during packaging storage, it is therefore prevented that user is wrongly installed or the risk of neglected loading parts.
Brush cutter provided by the invention, operator's handle when operating machine is parallel to operator's health, and work head is positioned at operator's dead ahead, operates comfortable and handle and will not keep off lower limb. Handle can rotate around both direction simultaneously, can effectively reduce and take up room, convenient for collecting. It is pointed out that above-mentioned preferred embodiment is only the technology design and feature that the present invention is described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this. All equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
