Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1 to Fig. 3, hand-held tool of the present invention comprise housing, enclosure interior Power Component (not shown), drive the work package 1 with executing means function by Power Component, described work package 1 from housing along the longitudinal axis stretch out forward.
In order to make instrument have higher flexible applicability, install one outward for providing the power brick 2 of electric power for instrument at housing.Power brick 2 is dismountable, and can arrange in power brick 2 for forming with housing the slide rail be slidably connected, and certainly, housing must be provided with the slide construction coordinated with slide rail, this is apparent, does not repeat herein.
Preferred as one, we in a handheld electric trimmer be that example is described, work package 1 is shrub and hedge trimmer, and its position of centre of gravity is positioned at the G1 place shown in Fig. 1.Power brick 2 and Power Component are the main weight places of instrument, and wherein, Power Component is positioned at enclosure interior, and in order to ensure that user can keep balance, laborsaving, indefatigability in operation, we are optimized design to the position of power brick 2.It should be noted that, length direction involved in the present invention all refers to: the direction of the vertical join line on corresponding parts between distance two faces farthest.
The first in command 3 for holding is also had in the outside of housing, and this first in command 3 is arranged at the outside of housing and is arranged in the rear of the center of gravity G2 of hand-held tool, the first in command 3 is a longitudinal handle in the present embodiment, and described power brick 2 is installed from the side of hand-held tool and described power brick is at least mainly arranged at the below of the first in command.
Also be provided with a second in command 4 in hull outside, and this second in command 4 forms or is arranged at the outside of housing and is arranged in the front of the first in command, the second in command is a horizontal handle in the present embodiment.Preferred as one, the second in command 4 is shaped with housing split, and is provided with for the fixed arm fixing with housing.Reliable fixing in order to ensure, the fixed arm of the second in command 4 is fixed together by screw and housing.
It should be noted that, shown in Figure 3, by the center of gravity G1 of work package 1 and the straight line being parallel to its length direction is middle separated time 6, wherein, separated time 6 is identical with the direction of housing longitudinal axis or parallel, and the first in command 3 and the second in command 4 are about middle separated time 6 one-tenth symmetry; And two handles are all provided with the handle for finger grip, increase operation time comfortableness, wherein, in the length direction of the first in command 3 handle, separated time 6 is in a plane, both can structure at a certain angle, also can be parallel to each other; The length direction of the second in command 4 handle is then perpendicular to the plane that middle separated time 6 is formed jointly with the first in command.Like this, the strength advantageously in operator is distributed and gravity's center control, not easily produces sense of fatigue.
In addition, in order to ensure safety when operating further, have safeguard structure in the position of hull outside installment work assembly 1, this safeguard structure can be integrally formed with housing, also can be mounted in parts on hand-held tool, safeguard structure is preferably protective plate 5.
In order to understand better and describe the present invention, see Fig. 4, we define a 3 D stereo coordinate system, using the plane being not only parallel to middle separated time 6 but also being parallel to power brick 2 and the relative sliding direction of housing as XY plane, Y-axis overlaps with middle separated time 6, and the direction that work package 1 extends is the positive direction of Y-axis, so, the positive direction along Y-axis sets gradually: power brick 2, the second in command 4, safeguard structure and work package 1; Power brick 2 extends to the first in command 3 and is set to the positive direction of Z axis with the direction of XY plane orthogonal.
Said above, power brick 2 slips into housing and forms with housing and be connected, in the present invention, in the angle that glide direction and Y-axis are formed, less one is greater than 0 degree, that is, as shown in Figures 5 to 7, power brick 2 can be installed on the housing of hand-held tool in following three kinds of modes, is respectively to be installed on housing, from the back sweep of the side of hand-held tool from the lateral vertical of hand-held tool to be installed on housing, from the front, side of hand-held tool to tilt to be installed on housing.
Figure 8 shows that the first in command 3, the second in command 4 and the projection of power brick 2 in YZ plane, the projection of the first in command 3 is positioned at the upper left side of power brick 2 projection and defines encirclement to the projection of power brick 2.Wherein, a left side refers to the negative direction of Y-axis, above refers to the positive direction of Z axis.The projection of the second in command 4 is then tilted to the positive direction of Y-axis.So, power brick 2, between the second in command 4 and the first in command 3, ensures reliably to grip, controls center of gravity, and operator not easily feels tired, can increase work efficiency.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
