The two edges of the bottom plate are respectively provided with an upturning barrier strip, which is helpful for stopping and limiting the mainframe box placed on the bottom plate.

The bottom plate is provided with two hollowed lightening holes, which is beneficial to lightening the whole weight of the bottom plate.

Two pairs of elastic binding bands are connected between the two barrier strips, so that the mainframe box can be bound on the bottom plate, and the fixing effect is enhanced.

The bottom plate upper surface is equipped with many parallel convex strips that go up protrudingly, and the convex strip is the elasticity strip, reinforcing frictional force, improves anti-skidding effect.

With the prior art, the utility model, following beneficial effect has.

The utility model discloses a rotatory butterfly screw rod drives the lifter then and rises or descends, during the removal bracket, upwards spins the butterfly screw rod and makes the sucking disc highly be higher than ground bottom, when needs fixing bracket, only needs make sucking disc and glossy floor brick face contact adsorb ground downwards with the butterfly screw rod, with the firm fixed of bottom plate under the effect of 4 sucking discs, can not take place to rock.
