The fixing device is used to fix the embedded part 4 in the mechanical and electrical formwork 5. Among them: Fixing holes are drilled on the formwork 5 with an electric drill. The riveting body 2 and the threaded core pull 1 are installed in the fixing holes and the embedded part 4. The threaded core pull 1 is pulled with an electric rivet gun to make the riveting body 2 clamp tightly, and then the reverse pull expansion tube 3 is inserted into the threaded core pull 1.
[0006] The utility model also has the following additional technical features:

The middle of the core pull 1 is a core body with the same specification and does not break during the pulling process.
[0009] As a further specific optimization of the technical solution of the utility model: The four sides of the riveting body 2 are provided with three long holes for expanding and clamping at the bottom of the formwork 5 after the core pull 1, and the length can be controlled to adapt to different thicknesses of the formwork 5.
[0010] As a further specific optimization of the technical solution of the utility model: The reverse pull expansion tube 3 is made of plastic and has toughness; the outer side is provided with barbs around it to increase the reverse pulling force in the floor slab, and the inner side is provided with expansion holes for installing the threaded core pull 1.
