The utility model principle: the feeding amount of the two side tables into the containing space is controlled by adjusting the fixing device, different specifications of counterweight blocks are matched in turn, and the gap formed by the reduction of the counterweight blocks is filled, which is safe and reliable and has strong universality.

[0005] As an improvement, the main frame is in the shape of U, the main frame is provided with a containing groove, and the main column enters the containing space along the containing groove.

[0006] As an improvement, the fixing member is a locking bolt and a locking nut, the main frame is provided with a first fixing hole and a welded nut, the welded nut is fixed at the first fixing hole, and the locking bolt passes through the locking nut, the welded nut and the first fixing hole in sequence and abuts against the main column.

[0007] As improvement, the fixing member is a locking bolt and a locking nut, the main frame is provided with a first fixing hole, the two ends of the connecting plate are provided with a second fixing hole and a welding nut, the welding nut is fixed at the second fixing hole, and the locking bolt passes through the locking nut, the welding nut, the second fixing hole and the first fixing hole in sequence and abuts against the main column.

[0008] As improvement, the top and bottom of the two main frames are respectively provided with six connecting plates which are equidistantly distributed.

[0009] The utility model discloses the beneficial effects are: through the adjustment fixed device to control two side station's into the accommodation space's feed quantity, in turn to match different specifications of counterweight, and then fill up the gap formed by the reduction of counterweight, safe and reliable and strong versatility, the utility model discloses with channel steel groove iron as raw material, low cost and reusable.
