A kind of suspension gear that rises certainly comprises strut bar 1 and cantilevered leg 2, and it is characterized in that: strut bar 1 has elasticity, head has one group of breach that goes in ring, the height of breach is greater than the thickness of cantilevered leg 2, and the afterbody of cantilevered leg 2 has unthreaded hole, and the unthreaded hole diameter is greater than the diameter of strut bar 1;

Three described strut bars 1 are fixed on the support, and three described cantilevered leg 2 are fixed on and treat on the hanging object, and there is deviation in the triangle that the unthreaded hole center constitutes on triangle that the kernel of section on strut bar 1 top forms and the cantilevered leg 2; The top of mobile strut bar 1 in elastic limit, two triangle can overlap.

For realizing the purpose of this utility model, container or parts are fixed, cantilevered leg can be fixed on and treat on the hanging object, cantilevered leg is being treated distribution triangular in shape on the hanging object, the afterbody of each cantilevered leg has unthreaded hole, the unthreaded hole diameter is bigger slightly than strut bar, and the center of unthreaded hole constitutes triangle on three cantilevered leg.Correspondingly strut bar is fixed on the support, the kernel of section on its top forms a triangle similar to above-mentioned triangle, and the triangle that the center of unthreaded hole constitutes on the length of side and the cantilevered leg is deviation to some extent.The strut bar head is manufactured with one group of breach that goes in ring for one section, and the thickness of the aspect ratio cantilevered leg of breach is bigger.Make strut bar respectively by the unthreaded hole of cantilevered leg afterbody then, the elasticity owing to strut bar snaps in the belt breach of strut bar cantilevered leg, thereby plays the effect of location.In the time of need regulating the position of fixture, as long as the top of pulling strut bar, make to move up and down after the centres of unthreaded hole on the kernel of section of supporting bar top and the cantilevered leg and treat fixed object, after three place's contact points move the breach of same number, can guarantee to treat the level relatively of fixture position.

For the object that the utility model is hung more stable, can make the state for the treatment of that the cantilevered leg on the hanging object is evenly distributed that is fixed on, the center of unthreaded hole constitutes equilateral triangle on three cantilevered leg, make the center of gravity for the treatment of hanging object be positioned at equilateral triangle the center, and determine that correspondingly strut bar is fixed on the position on the support.For regulating the position for the treatment of hanging object easily, the belt breach of strut bar head can be made as equidistant belt breach, whenever moves a breach, moves or move down identical distance on the hanging object.

The principle that the utility model utilized is, 3 on same straight line can not determine a plane, there are two groups of 3 points on the different straight lines in the utility model, first group of three point wherein, promptly be fixed on the center of the unthreaded hole on three cantilevered leg 2 treating on the hanging object, its relative position is determined, can't be changed; Be made up of the kernel of section that is fixed on strut bar 1 top on the support for second group 3, be distributed in three positions, because strut bar 1 usefulness elastic body constitutes, each point its center is relatively made slight displacement.Because first group 3 relative size and second group 3 relative size is deviation to some extent, if first group 3 and second group 3 are overlapped fully, elastic body strut bar 1 is inevitable stressed like this, thereby plays the purpose of tensioner.

It is not high that the utility model can be widely used in position accuracy demand, container that weight is less and parts fixing, and quick release need not use any instrument, gives and safeguards that cleaning brings great convenience; Save lot of materials simultaneously, reduced cost.
