Hollow glass complex tool

The invention discloses a hollow glass complex tool which comprises a rectangular rack as well as a plurality of positioning devices and a multidirectional linkage mechanism mounted on the rack, wherein the positioning devices on the left and right sides of the rack are connected with a first driving device and is driven by the first driving device to act; the first driving device is further connected with the multidirectional linkage mechanism; the multidirectional linkage mechanism is connected with the positioning devices on the front and rear sides of the rack via a second driving device,so that the positioning devices on the front and rear sides of the rack are driven to act; and the positioning devices are used for positioning and enabling the outer edges of all layers of glass andkeels to be aligned with each other. The hollow glass composite tool is simple in structure, convenient to operate and high in cost performance, improves the size precision of the composite relative position of hollow glass, i
