Inside each plug-in hole, a magnet block 7 for adsorbing the metal sheet 6 is fixed. The metal sheet 6 is fixed on the end surface of the head of each plug-in end 8. A plurality of plug-in ends 8 are all fixed to the side wall of the vertical end of the same L-shaped cover 5;

A magnet 11 is provided inside the polyurethane sleeve. A reserved groove for installing the first electromagnetic shielding cloth 12 is formed inside the lower end wall of the housing 1. Considering that most of the existing LED driving power supplies for outdoor use are installed at high altitudes or placed on the ground. When using the LED driving power supply at a concert or a large music festival, high-altitude installation is not conducive to disassembly after the event, and it is inconvenient for the staff to debug the LED device. And placing it on the ground is prone to damage. The utility model uses the polyurethane sleeve located at the bottom of the housing 1 and the magnet 11 inside it to magnetically fix the device. When using the LED driving power supply outdoors or at a concert venue, it only needs to use the magnet 11 to magnetically adsorb the device on a metal plate that can be adsorbed. And in order to protect the surface of the magnet 11 from swelling and generating wounds during the adsorption process, a polyurethane protective sleeve 10 is sleeved on the surface of the magnet 11, which can protect the contact surface between the magnet 11 and the metal plate from damage. And in order to avoid the magnetic force of the magnet 11 affecting the inside of the device, a first layer of barrier is carried out between the housing 1 and the magnet 11 through the connecting seat 9, and a second layer of barrier can be carried out by using the first electromagnetic shielding cloth 12, so as to protect the inside of the housing 1 from interference.
