[0008] By adopting the above technical solution, the mounting plate abuts against the machine body, the mounting hole on the mounting plate coincides with the mounting hole on the machine body, the abutment block drives the two abutment rods to pass through the mounting holes, and under the action of the driving device and the abutment assembly, the ends of the abutment rods abut against the inner wall of the machine body, thereby realizing the installation of the fan cover.

[0009] Optionally, the driving device includes a driving spring and a driving ring which are sleeved on the connecting rod, wherein two ends of the driving spring are respectively fixed on the driving ring and the abutment block and pull the driving ring to move in a direction close to the abutment block, and the driving ring is rotatably connected to two telescopic rods, one end of the telescopic rod is rotatably connected to the driving ring, and the other end of the telescopic rod is rotatably connected to the corresponding abutment rod, and a positioning ring is fixed on the connecting rod, and the positioning ring is located between the abutment block and the driving ring. When the driving ring abuts against the positioning ring under the action of the driving spring, the end of the abutment rod abuts against the machine body.

[0010] By adopting the above technical solution, during the installation process, the two abutment rods pass through the mounting hole. In the process of sliding along the inner wall of the mounting hole, the angle between the two abutment rods becomes smaller, which facilitates the abutment rod to pass through the mounting hole. After the abutment rod completely passes through the mounting hole, under the action of the driving spring, the driving ring is pulled toward the direction close to the abutment block and abuts against the positioning ring. The telescopic rod leads the two abutment rods to move in the direction of increasing the angle, and under the joint action of the abutment assembly, the ends of the two abutment rods are pressed tightly against the inner wall of the machine body.

[0013] Optionally, a driving rod is fixed on the driving ring for facilitating pulling the driving ring to move on the connecting rod, the driving rod is parallel to the connecting rod, and the driving rod passes through the abutting disk and the fixed disk.

[0014] By adopting the above technical solution, the setting of the drive rod makes it easy to pull the drive ring to slide on the connecting rod, thereby making it easy to reduce the angle between the two abutment rods, and then making it easy for the connecting rod to drive the abutment rod to disengage from the mounting hole, thereby facilitating the removal of the fan cover.

[0015] Optionally, a positioning groove is provided at one end of the driving rod away from the driving ring, and a positioning rod is rotatably connected in the positioning groove.

At this time, the angle between the two abutting rods is reduced, which facilitates the removal of the connecting part.

[0016] By adopting the above technical solution, the staff can pull the driving rod to drive the driving ring to move in the direction away from the positioning ring, so that the angle between the two abutting rods becomes smaller, which is convenient for removing the connecting part. At this time, the positioning rod is rotated to make the positioning rod accommodated in the positioning groove, and the positioning block abuts against the fixed plate to prevent the driving ring from moving toward the positioning ring under the action of the driving spring.

[0017] Optionally, the cover assembly includes a cover fixed on a mounting plate, the cover is in a cylindrical shape, and a mounting cover with a mesh is threadedly connected to the cover.
