Currently, the method of fixing objects on cement is with cement nails or expansion screws. Cement nails are objects made of hard alloy steel that look like iron nails, which are composed of nail tips and nail bodies. Cement nails are hammered into the cement. Cement nails are easy to drive in, but not removable. The expansion screw is composed of a large end screw, a slotted sleeve, a gasket, a spring washer, and a nut. When using, first drill a hole in the cement with an electric hammer, put in the expansion screw, and tighten the nut to make the slotted sleeve expand at the tail of the big tail screw, so as to fix the expansion screw on the cement. At this time, unscrew the nut to install a fixed object on the expansion screw. Although this method can be disassembled, an electric hammer is required for the first installation, which is inconvenient.

When using ordinary hexagon head bolts or ordinary T-bolts with the oval groove structure, the bolts need to be inserted from the back of the groove. When the bolts cannot be inserted from the back of the groove due to the structural limitations of the steel base or the platform itself, it is often necessary to open the installation surface. Large diameter hand holes allow for easy mounting of bolts, which weakens the inherent strength and rigidity of a steel base or platform.

When fixing the centrifugal fan, since the gaskets, washers and nuts are separate parts, many parts are used in the whole process, and it is easy to miss the installation of parts; The volume of the parts is relatively small, and it is not easy to remove them when they are transferred into the air conditioner through the gap of the centrifugal fan blades, resulting in foreign bodies in the machine.

When people use a screwdriver and other tools to screw a screw into an object, they need one hand to hold the screw and the other to hold the screwdriver and other tools, which brings some inconvenience to the user; especially when the screw is not correctly set, it will cause work and time delays, affecting work efficiency. .

The grooved embedded parts are usually connected by bolts, and there are many types of T-bolts used with the grooved embedded parts. position, so that the T-bolt can form a stable connection with the groove-type embedded part, but in the actual installation process, the T-bolt pressed into the groove-type embedded part is prone to loosening problems, so it is difficult to better Fixed in trough embedded parts.
