[0012] As a further description of the above technical solution:

[0013] The top end of the top plate is connected with an annular plate, and the connecting strip is slidably connected to the top end of the annular plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, by setting up an auxiliary component, the mounting block can be moved to a specified angle by rotating the connecting strip, and at the same time, by rotating the screw rod, the mounting block can be moved to a specified position, so that the bolt can be passed through the vent hole at the bottom end of the host power supply chamber and connected to the inside of the mounting block, thereby fixing the bottom end of the power supply and the bottom end of the power supply chamber to avoid a gap therebetween, which would cause the cooling fan inside the power supply to generate greater vibration and noise when working.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
