Problems solved by technology
[0002] In the field of construction, thermal insulation boards have been used as energy-saving and environmentally friendly components. The existing construction technology is to bond expansion nails to make it firmly connected with the building facade. The existing expansion nails have a vertical structure after fixing the building facade. Screw, the screw has a flat head to penetrate the insulation board. It is laborious, and the position of the insulation board is not easy to align after the insertion. The screw sticks out of the insulation board. Insulation boards, these issues are still to be solved by technology

Description
technical field [0001] The invention relates to a tool used for installing a thermal insulation board, in particular to a fixed connection device for an outer top type thermal insulation board. Background technique [0002] In the field of construction, thermal insulation boards have been used as energy-saving and environmentally friendly components. The existing construction technology is to bond expansion nails to make it firmly connected with the building facade. The existing expansion nails have a vertical structure after fixing the building facade. Screw, the screw has a flat head to penetrate the insulation board. It is laborious, and the position of the insulation board is not easy to align after the insertion. The screw sticks out of the insulation board. Insulation boards, these problems still need to be solved by technology. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fixed connection device for an ou...
