The invention relates to a bonding tool capable of simultaneously bonding various parts onto a glass panel. The bonding tool comprises a frame body which is provided with a table board and an upper mounting plate, and at least one set of a bonding structure. The bonding tool is characterized in that the bonding structure comprises a peripheral limiting structure for peripherally restraining the glass panel, a first lay-up block which is fixed on the table board for restraining a glass panel bracket, a second lay-up block which is fixed on the table board for restraining a first switch bracket, a third lay-up block which is fixed on the table board for restraining a second switch bracket, and a pressure maintaining block which is arranged above the table board, is driven by a pressure maintaining air cylinder mounted on the upper mounting plate to move up and down vertically, wherein the pressure maintaining block is pressed for pressing the glass panel to the bonding surface of each bracket to carry out pressure maintaining. The tool works once, so that not only can the glass bracket and the switch bracket be bonded onto the glass panel, but also bonding mounting of switch brackets of different models on the glass panel can be adapted, and therefore, the tool has the advantages of high bonding efficiency and high bonding precision, less processes, and convenient operation.
