Friction sleeve 141, described friction sleeve is removably attachable on described leg.
Further, the bottom side of described leg 142 is the first bar-shaped trough 1422 and the second bar-shaped trough 1425, the bottom side of the inwall of described friction sleeve is the first groove 1411 and the second groove 1412, it is first lobe suitable with described first groove in described first bar-shaped trough, is second lobe suitable with described second groove in described second bar-shaped trough.
Further, described first lobe includes the first projection 1421, and described first projection is slided relative to described first bar-shaped trough and arranged.
Further, described second lobe includes the second projection 1424, and described second projection is slided relative to described second bar-shaped trough and arranged.
Further, described first is protruding and be the second spring 1423 between described first bar-shaped trough, and described second is protruding and be the 3rd spring 1426 between described second bar-shaped trough.
Further, the section configuration of described first lobe, the section configuration of the i.e. first projection is convex shape, the section configuration of described second lobe, the section configuration of the i.e. second projection is to be also convex shape, and so, leg and friction sleeve are in addition to mating with each other in shape, the bonding strength between them is further enhanced, it is to avoid balance makes unnecessary colliding with during carrying or moving also by first protruding, the second projection and the first bar-shaped trough, the second bar-shaped trough.
Work process of the present utility model is as follows:
nullWhen operator uses this utility model，Friction sleeve is first connected on leg by operator，A support component is rotated，It is at vertical state，So，When article to be measured are positioned on the first pallet or the second pallet by operator，Due to himself gravity，Corresponding side the first load bearing arm or the second load bearing arm move downward，Simultaneously，First support arm or the second support arm are moved downward，Simultaneously，Support beam is moved downward along cylinder，And then the first load bearing arm or the second load bearing arm moved downward carry out buffer shock-absorbing，When counterweight is placed on the second pallet or the first pallet by person to be operated，Balance gradually restores balance state，So，Effectively shorten the time required for balance adjustment during balance measurement，The first pallet or the second pallet without one hand rest of operator，Another hands places article to be measured or counterweight，More or two operator's work compounds，Simultaneously，Pedestal will not be collided with by the first load bearing arm or the second load bearing arm，Whole operating process is simple.
The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to scope of the present utility model.Any those skilled in the art, equivalent variations done on the premise of without departing from design of the present utility model and principle and amendment, the scope of this utility model protection all should be belonged to.
