Second device 2 comprises one first element 21, one second element 22 and a three element 23.First element 21 comprises one first connecting portion 211 and one first contact site 212, wherein, first connecting portion 211 is articulated in first articulated section 121 of second body 12, first contact site 212 is to extend away from the mode of first connecting portion 211, and first contact site 212 is the first basal plane b01 that are contacted with pedestal B in separable mode, so to have constituted a cantilever rod member.Second element 22 comprises one second connecting portion 221 and one second contact site 222, wherein, second connecting portion 221 is articulated in second articulated section 122 of first body 11, second contact site 222 is to extend away from the mode of second connecting portion 221, and second contact site 222 is the first basal plane b01 that are contacted with pedestal B in separable mode, so to have constituted another cantilever rod member.Three element 23 articulates a Y type member that is arranged between first element 21 and second element 22, and setting element T1 is arranged on the three element 23 in the mode of protruding.Three element 23 comprises a Y type body 230, a first axle part 231 and a second axle part 232.Setting element T1 is to protrude from the outer surface of Y type body 230.Y type body 230 comprises a U type opening 2300, wherein, Y type body 230 is cross-placed on second body 12 via U type opening 2300, be to be arranged at Y type body 230 between the first axle part 231 and the second axle part 232, and the first axle part 231 and the second axle part 232 are articulated in first element 21, second element 22 of second device 2 respectively with space and the mode by U type opening 2300.Hence one can see that, first element 21 of second device 2 is articulated in first articulated section 121 of second body 12, the first axle part 231 of three element 23 in order, and second element 22 of second device 2 is articulated in second articulated section 122 of second body 12, the second axle part 232 of three element 23 in order.Under the induced effect of three element 23 movably with the restriction of second body 12 of first device 1 under, first element 21 that is parallel to each other, second element 22 and first install 1 second body 12 and have constituted a double rocker mechanism jointly.In the present embodiment, first element 21, second element 22 are for having two rod members of same structure.
The 3rd device 3 is for power set of the Y type body 230 that is connected in second device, 2 three element 23, and is mobile between primary importance h1 and second place h2 to drive first body 11 by the 3rd device 3.The 3rd device 3 comprises a hawser 31, a motor 32 and a guide wheel group 33.Motor 32 is arranged on the first parts b-1 of pedestal B, and guide wheel group 33 is arranged on the second parts b-2 of pedestal B.Hawser 31 is connected in first element 21 of second device 2 via guide wheel group 33, motor 32 so moves between primary importance h1 and second place h2 with first body 11 that drives first device 1 in order to drive hawser 31.
Therefore, install at each second device, 2 first element 21 and second element the 22, the 3rd under the co-operate of 3 hawser 31, keep a both set a distance and guarantee that first installs 1 first body 11 and (for example: level) remain on a set state between the interior sidewall surface 110 of first device, 1 first body 11 and the first basal plane b01 of the first parts b-1 of pedestal B, and under the driving effect of the 3rd device 3 hawser 31, first body 11 of first device 1 can move back and forth between primary importance h1 and second place h2.
By the mobile route figure of setting element T1 shown in Figure 3 as can be known, be subjected to as setting element T1 under the driving of the 3rd device 3 hawser 31, setting element T1 moves along direction d1 and when being contacted with first section b21 of portion of the second basal plane b02, at this position that setting element T1 is contacted with first section b21 of portion of the second basal plane b02 is defined as one first reference position h01.
When by the 3rd device 3 hawser 31 continue to drive for setting element T1 the time, setting element T1 just moves along first section b21 of portion and has passed through the arc end part r01 of the first guidance part r1, and at first device 1 and a plurality of second device, part weight W of 2 that setting element T1 is connected ' effect under, setting element T1 just is led to the b20 of positioning section portion between first section b21 of portion and the second section b22 of portion, and this moment, first contact site 212, second contact site 222 of second element 22 of first element 21 kept in touch in the first basal plane b01.
When the 3rd device 3 hawser 31 stops to drive for setting element T1, setting element T1 just can be located in the b20 of positioning section portion between first section b21 of portion and the second section b22 of portion, will be defined as the first both allocation h3 in the position of the setting element T1 of the b20 of positioning section portion between first section b21 of portion and the second section b22 of portion in this.In other words, when the 3rd device 3 hawser 31 stops to drive for setting element T1 and setting element T1 when being positioned the b20 of positioning section portion between first section b21 of portion and the second section b22 of portion, just first of the assembled unit M1 device 1 is in a location state, and first contact site 212 of first element 21, second contact site 222 of second element 22 still keep in touch in the first basal plane b01 at this moment.
When by the driving once more for the b20 of positioning section portion of position between first section b21 of portion and second section b22 of portion of the 3rd device 3 hawser 31, setting element T1 has left the b20 of positioning section portion and has moved and passed through the arc end part r02 of the second guidance part r2 along second section b22 of portion along direction d1.At this position that setting element T1 is contacted with the arc end part r02 of the second guidance part r2 is defined as one second reference position h02.At first device 1 and a plurality of second device, part weight W of 2 that setting element T1 is connected ' effect under, setting element T1 just is led to the 3rd section b23 of portion and carries out along the moving down of direction d2 along the 3rd section b23 of portion, and this moment, first contact site 212, second contact site 222 of second element 22 of first element 21 still kept in touch in the first basal plane b01.
Under the driving force of the hawser 31 of suitably adjusting the 3rd device 3, the setting element T1 that moves along the 3rd section b23 of portion just can fully break away from from the second basal plane b02 of the 3rd parts b-3, in this setting element T1 is defined as one the 3rd reference position h03 from the position that the second basal plane b02 of the 3rd parts b-3 breaks away from fully.Under the second basal plane b02 with respect to the 3rd parts b-3, the second reference position h02 is the accessible extreme higher position of setting element T1, and the 3rd reference position h03 is the accessible extreme lower position of setting element T1.
In brief, no matter be the forward and backward of the setting element T1 second basal plane b02 that is contacted with the 3rd parts b-3, or setting element T1 contacts mobile along the second basal plane b02 of the 3rd parts b-3, first contact site 212 of first element 21, second contact site 222 of second element 22 remain and are contacted with the first basal plane b01, remain on set state with first body 11 of guaranteeing first device 1 thus.
Thus, by jacking system E1 just can be easily for the objects such as light fixture desiring to hang position, install or remove.
