The installation groove 31 is used for penetrating a prestressed steel wire rope, so as to fix the connection device on the prestressed steel wire rope. The pressing grooves 50 on both sides between the middle bracket 10 and the top bracket 20 are used for installing the photovoltaic module 70. Since the photovoltaic module 70 can be installed on both sides of the connection device, the installation quantity of the connection device is reduced, thereby improving the construction efficiency.
