Composite tool for hollow glass

The hollow glass compounding tool comprises a rectangular rack, a plurality of positioning devices and a plurality of multi-directional linkage mechanisms, the positioning devices on the left side andthe right side of the rack are connected with first driving devices respectively and driven by the first driving devices to move, and the first driving devices are further connected with the multi-directional linkage mechanisms; the multi-directional linkage mechanism is connected with the positioning devices on the front side and the rear side of the rack through a second driving device so as todrive the positioning devices on the front side and the rear side of the rack to act. And the positioning device is used for positioning and aligning the outer side edges of each layer of glass and the keel. The hollow glass is simple in structure, convenient to operate and high in cost performance, the size precision of the relative position of hollow glass compositing is improved, the overall strength of the hollow glas
