The specific embodiment

Being preferred embodiment elaborated to the utility model clamping device below in conjunction with accompanying drawing.

Referring to accompanying drawing 1-2.Boatswain chair 1 is positioned at the top of whole utility model clamping device, offers a lifting hole(eyelet) on it, the parts such as suspension hook of driving can be hooked in lifting hole(eyelet); Boatswain chair 1 below is fixed with the first adapter shaft 3, and its effect is connecting hanging arm support 2.Wherein the quantity of arm support 2 can be a plurality of, is preferably 2 in the present embodiment, and it is located at respectively the two ends of the first adapter shaft 3; If the quantity of arm support 2 surpasses 2, can the parallel distribution along the length direction of the first adapter shaft 3.Each arm support 2 is by connecting rod 21 on first, on second, connecting rod 22, the first lower link 23 and the second lower link 24 form, wherein on connecting rod 21 and second, the upper end of connecting rod 22 is hinged on the first adapter shaft 3 on first, on the upper end of the first lower link 23 and first, the lower end of connecting rod 21 is hinged by the second adapter shaft 4, on the upper end of the second lower link 24 and second, the lower end of connecting rod 22 is hinged by the 3rd adapter shaft 5, the first adapter shaft 3, the axial line of the second adapter shaft 4 and the 3rd adapter shaft 5 be take parallel to each other as best, the rod member of all like this arm supports 2 can be accomplished synchronously when occurrence positions changes, the middle part of the first lower link 23 and the second lower link 24 is hinged, and both just become X-shaped to connect like this.Because the rod member of hinge-point everywhere can rotate, therefore whole arm support 2 can vertically fold or launch.Lower end at the first lower link 23 and the second lower link 24, is equipped with hook 25, and hook 25 is oppositely arranged, and forms a grasping part that can clamp object, and in the folding process of arm support 2, the size of this grasping part can change.In order to increase the intensity of a plurality of arm supports 2, can between them, add the 4th adapter shaft 7, the four adapter shafts 7 preferably and the axis parallel of the first adapter shaft 3.

For the function of clamping is realized, just need to there is pair grasping part stationary device, in the present embodiment, adopted adjust bar 6.One end of adjust bar 6 is fixedly connected on the 3rd adapter shaft 5, the other end passes from the direction of the second adapter shaft 4, and being provided with a plurality of detents 61 in the one end near the second adapter shaft 4, the opening of each detent 61 is downward, and distributes along the length bearing of trend of adjust bar 6.The size of a grasping part that each detent 61 is corresponding, is arranged in the second adapter shaft 4 in corresponding detent 61, just can realize the locking to this grasping part.
