Fig. 1 is embodiment of the present invention brush saw schematic diagram.
Fig. 2 is embodiment of the present invention adjusting part cutaway view.
Fig. 3 is embodiment of the present invention brush saw reception position schematic diagram.
Embodiment
Be embodiment of the present invention brush saw as shown in Figures 1 to 3, it comprises working head 1, mobile jib 2, handle 3, adjusting part 4 and Power Component 5, described working head 1 and Power Component 5 lay respectively at mobile jib 2 two ends, and the power that Power Component produces makes working head 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 location and non-use position, and preferred, in the present embodiment, use location only has one.When handle 3 is positioned at use location, adjusting part 4 can be fixed on handle 3 on mobile jib 2, and now handle 3 cannot rotate.When handle 3 is positioned at non-use position, adjusting part 4 cannot be fixing by handle 3.Described mobile jib 2 has mobile jib axis Y, and mobile jib axis Y is the central axis of mobile jib.Described handle 3 comprises pipe portion 31 and operating portion 32, and operating portion 32 has two, lays respectively at pipe portion 31 both sides, make the shape of handle 3 roughly become U-shaped, pipe portion 31 has pipe portion axis X, and pipe portion axis X is the central axis of pipe portion 31, and vertical axis Z is perpendicular to axis X and Y place plane.Adjusting part 4 fixes handle by stationary pipes portion 31, and operating portion 32 grips when using machine to operator and controls.When handle 2 is during at operating position, mobile jib axis Y and pipe portion axis X oblique, form pincer attack A, and the scope of included angle A is 75 ° to 85 °, and more specifically, the present embodiment included angle A is 80 °.In operator P(Fig. 1, circle represents operator) stand in brush saw left side, when operator's both hands are held operating portion 32, working head 1 is positioned at the dead ahead of operator's sight line, and now handle 3 is parallel to operator's health, and can not keep off leg, meets ergonomics.When operation adjusting part 4 is removed after fixing of handle 3, handle 3 can be simultaneously around pipe portion axis X and vertical axis Z rotation, and handle 3 can be turned to non-use position, and at non-use position, adjusting part 4 cannot be fixing by handle 3.Described non-use position comprises reception position, handle 3 is rotated to pipe portion axis X and mobile jib axis Y almost parallel around vertical axis Z, now the shared space of handle 3 has just reduced, further, handle 3 is rotated around pipe portion axis X again, make operating portion towards mobile jib side (as shown in Figure 3), now handle 3 just can not take the large quantity space of brush saw top, saved space, instant packed and take in.Described handle 3 also can move along pipe portion axis X direction, so operator's capable of regulating handle is in the position of the mobile jib left and right sides, and handle 3 can move to operator's left hand or right-hand lay.
As shown in Figure 2, adjusting part 4 comprises knob 41, Handleset and mobile jib assembly, and Handleset comprises handle upper cover 42, handle lower cover 43.Mobile jib assembly comprises 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, then adjust that to insert knob 41 after angle fixing.Knob 41 comprises screw rod 411, and knob screws by screw rod and threaded engagement.Shown in the vertical axis Z central axis that is screw rod.Described adjusting part 4 also comprises the first spring 46 and the second spring 47, the first spring 46 is arranged between handle upper cover 4 and handle lower cover 43, unscrew after knob 41, the first spring is separated with handle lower cover by handle upper cover by elastic force, and handle 3 can be rotated around pipe portion axis X.The second spring is arranged between handle lower cover 43 and mobile jib upper cover 44, unscrews after knob 41, and the second spring is separated with mobile jib upper cover 44 by handle lower cover 43, and Handleset and mobile jib assembly can be relatively rotated, so handle 3 can rotate around vertical axis Z.Between Handleset and mobile jib assembly, by tooth portion 441, be fixed with the groove being arranged on handle lower cover 43.Adjusting part 4 of the present invention is fixed handle by operation knob 41 or removes fixingly, and do not need other instruments, packing does not need to pull down handle while taking in yet, and prevented the risk of the wrongly installed or neglected loading parts of user.
Brush saw provided by the invention, operator's handle when operating machines is parallel to operator's health, and working head is positioned at operator dead ahead, operates comfortable and handle and can not keep off leg.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 explanation technical conceive of the present invention and feature, its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the 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.
